Consider:
./mysqladmin -u root -p** '_redacted_'
Output (including typing the password):
Enter password:
mysqladmin: connect to server at 'localhost' failed error:
'Access denied for user 'root'#'localhost' (using password: YES)'
How can I fix this?
All solutions I found were much more complex than necessary and none worked for me. Here is the solution that solved my problem. There isn't any need to restart mysqld or start it with special privileges.
sudo mysql
-- for MySQL
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
-- for MariaDB
ALTER USER 'root'#'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('root');
With a single query we are changing the auth_plugin to mysql_native_password and setting the root password to root (feel free to change it in the query).
Now you should be able to log in with root. More information can be found in MySQL documentation or MariaDB documentation.
(Exit the MySQL console with Ctrl + D or by typing exit.)
Open and edit /etc/my.cnf or /etc/mysql/my.cnf, depending on your distribution.
Add skip-grant-tables under [mysqld]
Restart MySQL
You should be able to log in to MySQL now using the below command mysql -u root -p
Run mysql> flush privileges;
Set new password by ALTER USER 'root'#'localhost' IDENTIFIED BY 'NewPassword';
Go back to /etc/my.cnf and remove/comment skip-grant-tables
Restart MySQL
Now you will be able to login with the new password mysql -u root -p
None of the previous answers helped me with this problem, so here's the solution I found.
The relevant part:
In Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. This allows for some greater security and usability in many cases, but it can also complicate things when you need to allow an external program (e.g., phpMyAdmin) to access the user.
In order to use a password to connect to MySQL as root, you will need to switch its authentication method from auth_socket to mysql_native_password. To do this, open up the MySQL prompt from your terminal:
sudo mysql
Next, check which authentication method each of your MySQL user accounts use with the following command:
SELECT user,authentication_string,plugin,host FROM mysql.user;
Output
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | | auth_socket | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
In this example, you can see that the root user does in fact authenticate using the auth_socket plugin. To configure the root account to authenticate with a password, run the following ALTER USER command. Be sure to change password to a strong password of your choosing, and note that this command will change the root password you set in Step 2:
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
Then, run FLUSH PRIVILEGES which tells the server to reload the grant tables and put your new changes into effect:
FLUSH PRIVILEGES;
Check the authentication methods employed by each of your users again to confirm that root no longer authenticates using the auth_socket plugin:
SELECT user,authentication_string,plugin,host FROM mysql.user;
Output
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | *3636DACC8616D997782ADD0839F92C1571D6D78F | mysql_native_password | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
You can see in this example output that the root MySQL user now authenticates using a password. Once you confirm this on your own server, you can exit the MySQL shell:
exit
I tried many steps to get this issue corrected. There are so many sources for possible solutions to this issue that is is hard to filter out the sense from the nonsense. I finally found a good solution here:
Step 1: Identify the database version
mysql --version
You'll see some output like this with MySQL:
mysql Ver 14.14 Distrib 5.7.16, for Linux (x86_64) using EditLine wrapper
Or output like this for MariaDB:
mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1
Make note of which database and which version you're running, as you'll use them later. Next, you need to stop the database so you can access it manually.
Step 2: Stopping the database server
To change the root password, you have to shut down the database server beforehand.
You can do that for MySQL with:
sudo systemctl stop mysql
And for MariaDB with:
sudo systemctl stop mariadb
Step 3: Restarting the database server without permission checking
If you run MySQL and MariaDB without loading information about user privileges, it will allow you to access the database command line with root privileges without providing a password. This will allow you to gain access to the database without knowing it.
To do this, you need to stop the database from loading the grant tables, which store user privilege information. Because this is a bit of a security risk, you should also skip networking as well to prevent other clients from connecting.
Start the database without loading the grant tables or enabling networking:
sudo mysqld_safe --skip-grant-tables --skip-networking &
The ampersand at the end of this command will make this process run in the background so you can continue to use your terminal.
Now you can connect to the database as the root user, which should not ask for a password.
mysql -u root
You'll immediately see a database shell prompt instead.
MySQL Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
MariaDB Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>
Now that you have root access, you can change the root password.
Step 4: Changing the root password
mysql> FLUSH PRIVILEGES;
Now we can actually change the root password.
For MySQL 5.7.6 and newer as well as MariaDB 10.1.20 and newer, use the following command:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'new_password';
For MySQL 5.7.5 and older as well as MariaDB 10.1.20 and older, use:
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('new_password');
Make sure to replace new_password with your new password of choice.
Note: If the ALTER USER command doesn't work, it's usually indicative of a bigger problem. However, you can try UPDATE ... SET to reset the root password instead.
[IMPORTANT] This is the specific line that fixed my particular issue:
mysql> UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost';
Remember to reload the grant tables after this.
In either case, you should see confirmation that the command has been successfully executed.
Query OK, 0 rows affected (0.00 sec)
The password has been changed, so you can now stop the manual instance of the database server and restart it as it was before.
Step 5: Restart the Database Server Normally
The tutorial goes into some further steps to restart the database, but the only piece I used was this:
For MySQL, use:
sudo systemctl start mysql
For MariaDB, use:
sudo systemctl start mariadb
Now you can confirm that the new password has been applied correctly by running:
mysql -u root -p
The command should now prompt for the newly assigned password. Enter it, and you should gain access to the database prompt as expected.
Conclusion
You now have administrative access to the MySQL or MariaDB server restored. Make sure the new root password you choose is strong and secure and keep it in safe place.
After trying all others answers, this it what finally worked for me:
sudo mysql -- It does not ask me for any password
-- Then in MariaDB/MySQL console:
update mysql.user set plugin = 'mysql_native_password' where User='root';
FLUSH PRIVILEGES;
exit;
I found the answer in the blog post Solved: Error “Access denied for user ‘root’#’localhost’” of MySQL — codementor.tech (Medium).
For Ubuntu/Debian users
(It may work on other distributions, especially Debian-based ones.)
Run the following to connect as root (without any password)
sudo /usr/bin/mysql --defaults-file=/etc/mysql/debian.cnf
If you don't want to add --defaults-file each time you want to connect as root, you can copy /etc/mysql/debian.cnf into your home directory:
sudo cp /etc/mysql/debian.cnf ~/.my.cnf
And then:
sudo mysql
In my experience, if you run without sudo it will not work. So make sure your command is;
sudo mysql -uroot -p
For new Linux users this could be a daunting task. Let me update this with MySQL 8 (the latest version available right now is 8.0.12 as on 2018-09-12)
Open "mysqld.cnf" configuration file at "/etc/mysql/mysql.conf.d/".
Add skip-grant-tables to the next line of [mysql] text and save.
Restart the MySQL service as "sudo service mysql restart". Now your MySQL is free of any authentication.
Connect to the MySQL client (also known as mysql-shell) as mysql -u root -p. There is no password to be keyed in as of now.
Run SQL command flush privileges;
Reset the password now as ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPassword';
Now let's get back to the normal state; remove that line "skip-grant-tables" from "mysqld.cnf" and restart the service.
That's it.
In my case under Debian 10, the error
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
was solved by (good way)
sudo mysql -u root -p mysql
Bad way:
mysql -u root -p mysql
I did this to set my root password in the initial set up of MySQL in OS X. Open a terminal.
sudo sh -c 'echo /usr/local/mysql/bin > /etc/paths.d/mysql'
Close the terminal and open a new terminal.
And the following worked in Linux, to set the root password.
sudo /usr/local/mysql/support-files/mysql.server stop
sudo mysqld_safe --skip-grant-tables
(sudo mysqld_safe --skip-grant-tables: This did not work for me the first time. But on the second try, it was a success.)
Then log into MySQL:
mysql -u root
FLUSH PRIVILEGES;
Now change the password:
ALTER USER 'root'#'localhost' IDENTIFIED BY 'newpassword';
Restart MySQL:
sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server start
My Station here:
UBUNTU 21.04
PHP 5.6.40-57
MYSQL 5.7.37
let's config it
nano /etc/mysql/mysql.conf.d/mysqld.cnf
at the bottom, write this
skip-grant-tables
reload it
service mysql restart
In your MySQL Workbench, you can go to the left sidebar, under Management select "Users and Privileges", click root under User Accounts, in the right section click tab "Account Limits" to increase the maximum queries, updates, etc., and then click tab "Administrative Roles" and check the boxes to give the account access.
Ugh - nothing worked for me! I have a CentOS 7.4 machine running MariaDB 5.5.64.
I had to do this, right after installation of MariaDB from YUM;
systemctl restart mariadb
mysql_secure_installation
The mysql_secure_installation will take you through a number of steps, including "Set root password? [Y/n]". Just say "y" and give it a password. Answer the other questions as you wish.
Then you can get in with your password, using
mysql -u root -p
It will survive
systemctl restart mariadb
The Key
Then, I checked the /bin/mysql_secure_installation source code to find out how it was magically able to change the root password and none of the other answers here could. The import bit is:
do_query "UPDATE mysql.user SET Password=PASSWORD('$esc_pass') WHERE User='root';"
...It says SET Password=... and not SET authentication_string = PASSWORD.... So, the proper procedure for this version (5.5.64) is:
Log in using mysql -u root -p, using the password you already set.
Or, stop the database and start it with:
mysql_safe --skip-grant-tables --skip-networking &
From the mysql> prompt:
use mysql;
select host,user,password from user where user = 'root';
(observe your existing passwords for root).
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root' AND host = 'localhost';
select host,user,password from user where user = 'root';
flush privileges;
quit;
Kill the running mysqld_safe. Restart MariaDB. Log in as root: mysql -u -p. Use your new password.
If you want, you can set all the root passwords at once. I think this is wise:
mysql -u root -p
(login)
use mysql;
select host,user,password from user where user = 'root';
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root';
select host,user,password from user where user = 'root';
flush privileges;
quit;
This will perform updates on all the root passwords: i.e., for "localhost", "127.0.0.1", and "::1"
In the future, when I go to RHEL 8 or what have you, I will try to remember to check the /bin/mysql_secure_installation and see how the guys did it, who were the ones that configured MariaDB for this OS.
Use sudo to alter your password:
sudo mysql
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'insert_password';
Source: Phoenixnap - Access denied for user root localhost
Fix for macOS
Install MySQL from https://downloads.mysql.com/archives/community/ (8.x is the latest as on date, but ensure that the version is compatible with the macOS version)
Give password for root (let <root-password> be the password) during installation (don't forget to remember the password!)
Select Use Legacy Password Encryption option (that is what I had used and did not try for Use Strong Password Encryption option)
Search and open MySQL.prefPane (use search tool)
Select Configuration tab
Click Select option of Configuration File
Select /private/etc/my.cnf
From terminal open a new or existing file with name /etc/my.cnf (vi /etc/my.cnf) add the following content:
[mysqld]
skip-grant-tables
Restart mysqld as follows:
ps aux | grep mysql
kill -9 <pid1> <pid2> ... (grab pids of all MySQL related processes)
mysqld gets restarted automatically
Verify that the option is set by running the following from terminal:
ps aux | grep mysql
> mysql/bin/mysqld ... --defaults-file=/private/etc/my.cnf ... (output)
Run the following command to connect (let mysql-<version>-macos<version>-x86_64 be the folder where MySQL is installed. To grab the actual folder, run ls /usr/local/ and copy the folder name):
/usr/local/mysql-<version>-macos<version>-x86_64/bin/mysql -uroot -p<root-password>
If you are like me and all the information in previous answers failed, proceed to uninstall all versions of MySQL on your machine, search for all remaining MySQL files using the command sudo find / -name "mysql" and rm -rf every file or directory with the "mysql" name attached to it (you should skip files related to programming language libraries).
Now install a fresh version of MySQL and enjoy. NB: You will lose all your data so weigh your options first.
Sometimes a default password is set when you install it - as mentioned in the documentation. This can be confirmed by the following command.
sudo grep 'temporary password' /var/log/mysqld.log
It can happen if you don't have enough privileges.
Type su, enter the root password and try again.
After trying a lot with the following answer:
ALTER USER 'root'#'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('root');
And similar answers, my terminal was still throwing me the following error:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near...
So after researching on the web, this line solved my problem and let me change the root user password:
sudo mysqladmin --user=root password "[your password]"
windows :
cd \Ampps\mysql\bin :
mysql.exe -u root -pmysql
after mysql start (you can see shell like this mysql> )
use this query :
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
try again access with root root
If you reached this page via Google like I did and none of the previous solutions worked, what turned out to be the error was 100% foolishness on my end. I didn't connect to the server. Once connected everything was smooth sailing.
In case it helps to know my setup, I'm using Sequel Pro and am trying to connect to it with Node using the NPM package, mysql. I didn't think I needed to actually connect (other than run Sequel Pro), because I was doing that from my application already.
I was getting the same error while setting up the mysql-8 zip version. Finally, switched to installer version which worked seamlessly. During installation, there is a prompt to set up the root password. Once set, it works for sure.
According to MariaDB official documentation, in MariaDB 10.4.3 and later, the unix_socket authentication plugin is installed by default.
In order to disable it, and revert to the previous mysql_native_password authentication method, add line below in [mysqld] section of my.cnf file:
[mysqld]
unix_socket=OFF
And then run:
mysql_install_db --auth-root-authentication-method=normal
And then start mysqld
This command will then work fine:
mysqladmin -u root password CHANGEME
For additional information, see Configuring mysql_install_db to Revert to the Previous Authentication Method.
I was trying to leverage Docker desktop on Mac to get 5.7.35 running and this docker-compose.yml configuration allowed it to work:
In particular it was the addition of the line...
command: --default-authentication-plugin=mysql_native_password
...that did the trick
version: '3.3'
services:
mysql_db:
image: mysql:5.7
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: 'your_password'
ports:
- '3306:3306'
expose:
- '3306'
volumes:
- ~/your/volume/path:/var/lib/mysql
One thing to check is the from-host filter. It may be "localhost" by default. Are you trying to connect from a remote client? Change this to "%".
On Arch Linux
Package: mysql 8.0.29-1
What worked for me:
Edit my.cnf file, normally can be found at /etc/mysql/my.cnf and append this skip-grant-tables at the bottom/end of the file.
Restart mysql service by invoking sudo systemctl restart mysqld
Ensuring mysql service has started properly by invoking sudo systemctl status mysqld
Login to mysql using 'root' by invoking mysql -u root -p
Flush privileges by invoking flush privileges;
Create new user by CREATE USER 'root'#'localhost' IDENTIFIED BY 'rootpassword';
(If you plan to use this db with PHP), you should instead use this CREATE USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'rootpassword';
Check whether your changes have reflected in db by invoking the following in sequence:
use mysql;
SELECT User, password_last_changed FROM user;
Exit mysql console and comment/remove skip-grant-tables by editing my.cnf file (Refer to step 1 for the location)
Restart the mysql service (Refer to step 2 and step 3)
And that's all.
The '-p' argument doesn't expect a space between the argument name and value.
Instead of
./mysqladmin -u root -p 'redacted'
Use
./mysqladmin -u root -p'redacted'
Or just
./mysqladmin -u root -p
which will prompt you for a password.
Solution: Give up!
Hear me out. I spent about two whole days trying to make MySQL work to no avail, always stuck with permission errors, none of which were fixed by the answers to this question. It got to the point that I thought if I continued I'd go insane.
Out of patience for making it work, I sent the command to install SQLite, only using 450 KB, and it worked perfectly right from the word go.
If you don't have the patience of a saint, go with SQLite and save yourself a lot of time, effort, pain, and storage space..!
I am continuously receiving this error.
I am using mySQL Workbench and from what I am finding is that root's schema privileges are null. There are no privileges at all.
I am having troubles across platforms that my server is used for and this has been all of a sudden issue.
root#127.0.0.1 apparently has a lot of access but I am logged in as that, but it just assigns to localhost anyways - localhost has no privileges.
I have done a few things like FLUSH HOSTS, FLUSH PRIVILEGES, etc
but have found no success from that or the internet.
How can I get root its access back? I find this frustrating because when I look around people expect you to "have access" but I don't have access so I can't go into command line or anything and GRANT myself anything.
When running SHOW GRANTS FOR root this is what I get in return:
Error Code: 1141. There is no such grant defined for user 'root' on
host '%'
If you have that same problem in MySql 5.7.+ :
Access denied for user 'root'#'localhost'
it's because MySql 5.7 by default allow to connect with socket, which means you just connect with sudo mysql. If you run sql :
SELECT user,authentication_string,plugin,host FROM mysql.user;
then you will see it :
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | | auth_socket | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *497C3D7B50479A812B89CD12EC3EDA6C0CB686F0 | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
To allow connection with root and password, then update the values in the table with command :
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'Current-Root-Password';
FLUSH PRIVILEGES;
Then run the select command again and you'll see it has changed :
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | *2F2377C1BC54BE827DC8A4EE051CBD57490FB8C6 | mysql_native_password | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *497C3D7B50479A812B89CD12EC3EDA6C0CB686F0 | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
And that's it. You can run this process after running and completing the sudo mysql_secure_installation command.
For mariadb, use
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('manager');
to set password.
More at https://mariadb.com/kb/en/set-password/
Use the instructions for resetting the root password - but instead of resetting the root password, we'll going to forcefully INSERT a record into the mysql.user table
In the init file, use this instead
INSERT INTO mysql.user (Host, User, Password) VALUES ('%', 'root', password('YOURPASSWORD'));
GRANT ALL ON *.* TO 'root'#'%' WITH GRANT OPTION;
It didn't like my user privilege so I SUDO it.
(in bash << sudo set user and password)
(this gives username of root and sets the password to nothing)

I was using ubuntu 18 and simply installed MySQL (password:root) with the following commands.
sudo apt install mysql-server
sudo mysql_secure_installation
When I tried to log in with the normal ubuntu user it was throwing me this issue.
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
But I was able to login to MySQL via the super user. Using the following commands I was able to log in via a normal user.
sudo mysql
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
exit;
Then you should be able to login to Mysql with the normal account.
If you are getting this error in Workbench but you are able to log in from terminal then follow this steps.
First simply log in with your current password:
sudo mysql -u root -p
Then change your password because having low strength password gives error sometimes.
ALTER USER 'root'#'localhost' IDENTIFIED BY 'new-strong-password';
FLUSH PRIVILEGES;
Then simply exit and again login with your new password:
quit
sudo mysql -u root -p
Once you successfully logged in type the command:
use mysql;
It should show a message like 'Database changed' then type:
UPDATE user SET plugin='mysql_native_password' WHERE User='root';
After that type:
UPDATE mysql.user set authentication_string=PASSWORD('new-strong-password') where user='root';
Then type:
FLUSH PRIVILEGES;
Then simply exit:
quit
Now try to log in with your new password in your WORKBENCH. Hope it will work. Thank you.
A simple way to reset root password on Linux systems :
sudo dpkg-reconfigure mysql-server-5.5
Checkout some other reasons for Access denied :
https://dev.mysql.com/doc/refman/5.7/en/problems-connecting.html
I faced this problem while installing Testlink on Ubuntu server, I followed these steps
mysql -u root
use mysql;
update user set password=PASSWORD("root") where User='root';
flush privileges;
quit
Now stop the instance and start again i.e
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start
For my case, I found this error after fresh installation of mysql on Mac OS Big Sur.
What i did to fix it was:
I click on the apple logo, go to system preferences and then click on mysql.
There's an initialize database button on the opened settings window, I click on that, and then when I try to access again, it's solved.
in mysql 5.7 the password field has been replaced with authentication_string so you would do something like this instead
update user set authentication_string=PASSWORD("root") where User='root';
See this link MySQL user DB does not have password columns - Installing MySQL on OSX
Well the easiest way to reset root password is:
restart mysqld --skip-grant-tables option. This enables anyone to
connect without a password and with all privileges. Because this is
insecure, you might want to use --skip-grant-tables in conjunction
with --skip-networking to prevent remote clients from connecting.
Connect to the mysqld server with this command:
shell> mysql Issue the following statements in the mysql client.
Replace the password with the password that you want to use.
mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass')
-> WHERE User='root'; mysql> FLUSH PRIVILEGES;
Stop the server, then restart it normally (without the --skip-grant-tables and --skip-networking options).
Source Mysql documentation and personal experience:
http://dev.mysql.com/doc/refman/5.6/en/resetting-permissions.html
I resolved the same issue by running Workbench as administrator.
...I guess it's because of restrictions on company computers, in my case...
MySQL default password for root is assigned depending on the way you have installed MySQL.
If you have installed it from MySQL Yum repository, MySQL SUSE repository, or RPM packages directly downloaded from Oracle, you can obtain the password using following command:
sudo grep 'temporary password' /var/log/mysqld.log
In my case:
I set plugin authentication to "" (empty) and I can't run mysql server:
SOLUTION:
nano /etc/mysql/my.cnf
edit:
[mysqld]
skip-grant-tables
service mysql restart
mysql -u root
use mysql
UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root'
flush privileges
Try out the following steps to overcome this issue:
Open terminal / command prompt and navigate to the bin folder of the MySQL installation folder. Then run the command mysqld --console.
If you can see that line 171010 14:58:22 [Note] --secure-file-priv is set to NULL. Operations related to importing and exporting data are disabled, after executing the above command from the command prompt.
Then you need to check that the mysqld is either blocked by the Windows Firewall or another program.
If it's blocked by Windows Firewall then need to unblock from it and save settings.
To unblock the mysqld or mysql application, follow the below steps:
Go to command prompt and type wf.msc to open the firewall settings.
Click on Allow an app or feature through Windows Firewall.
Check the mysqld or mysqld instances are available in the list and check the checkbox for the domain, public and private and save the settings.
Return to the bin folder and try the command from step 1 again.
It should work fine and not show any errors.
It should be possible to run the MySQL console without any problems now!
I resolved the same issue using next sql and restarting MySQL server:
update mysql.user set Select_priv='Y',Insert_priv='Y',Update_priv='Y',Delete_priv='Y',Create_priv='Y',Drop_priv='Y',Reload_priv='Y',Shutdown_priv='Y',Process_priv='Y',File_priv='Y',Grant_priv='Y',References_priv='Y',Index_priv='Y',Alter_priv='Y',Show_db_priv='Y',Super_priv='Y',Create_tmp_table_priv='Y',Lock_tables_priv='Y',Execute_priv='Y',Repl_slave_priv='Y',Repl_client_priv='Y',Create_view_priv='Y',Show_view_priv='Y',Create_routine_priv='Y',Alter_routine_priv='Y',Create_user_priv='Y',Event_priv='Y',Trigger_priv='Y',Create_tablespace_priv='Y'
where user='root';
I worked on Access Denied for User 'root'#'localhost' (using password: YES) for several hours, I have found following solution,
The answer to this problem was that in the my.cnf located within
/etc/mysql/my.cnf
the line was either
bind-address = 127.0.0.1
(or)
bind-address = localhost
(or)
bind-address = 0.0.0.0
I should prefer that 127.0.0.1
I should also prefer 0.0.0.0, it is more flexible
because which will allow all connections
I don't think you have to escape the --init-file parameter:
"C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld.exe" --defaults-file="C:\\Program Files\\MySQL\\MySQL Server 5.6\\my.ini" --init-file=C:\\mysql-init.txt
Should be:
"C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld.exe" --defaults-file="C:\\Program Files\\MySQL\\MySQL Server 5.6\\my.ini" --init-file=C:\mysql-init.txt
for the above problem ur password in the system should matches with the password u have passed in the program because when u run the program it checks system's password as u have given root as a user so gives u an error and at the same time the record is not deleted from the database.
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.Statement;
import java.sql.ResultSet;
class Delete
{
public static void main(String []k)
{
String url="jdbc:mysql://localhost:3306/student";
String user="root";
String pass="jacob234";
try
{
Connection myConnection=DriverManager.getConnection(url,user,pass);
Statement myStatement=myConnection.createStatement();
String deleteQuery="delete from students where id=2";
myStatement.executeUpdate(deleteQuery);
System.out.println("delete completed");
}catch(Exception e){
System.out.println(e.getMessage());
}
}
}
Keep ur system password as jacob234 and then run the code.
With me was the same problem, but it was caused, because i was using the mysql server on 32 (bit) and the workbench was running on 64(bit) version. the server and the workbench need to has the same version.
xpress
I was facing the same problem when I'm trying to connecting Mysql database using the Laravel application.
I would like to recommend please check the password for the user. MySQL password should not have special characters like #, &, etc...
cause might be missing mysqld file in /var/run/mysqld
sudo service mysql stop
sudo mysqld_safe --skip-grant-tables
sudo service mysql start
if file does not exits then create file
mkdir -p /var/run/mysqld
chown mysql:mysql /var/run/mysqld
check now you are able to login mysql -uroot -p123
otherwise do
sudo mysql -u root
use mysql;
show tables;
describe user;
update user set authentication_string=password('1111') where user='root';
FLUSH PRIVILEGES;
exit;
mysql -uroot -p123
link - mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists
For windows:-
If the instance configuration fails with similar issue and if you cannot log in to the root account.
Steps I followed to fix the issue:-
Stop MySql service if running.
Uninstall MySql using 'remove' option from the installation wizard.
If MySql service is not removed from services,
sc delete <MYSQL_SERVICE_NAME>
Delete all data containing in the MySql folder ('Program files', 'Program data' or the custom installation directory you have given).
Remove MySql path from the environmental variable.
Disable windows firewall.
Reinstall and config root account with new password.
the only thing that worked was sudo mysql followed by adding skip-grant-tables in [mysqld] section of /etc/my.cnf file - Ubuntu Mysql 5.5
alter user 'root'#'localhost' identified with mysql_native_password by '$your_password$';
it worked for me.
note: use strong password
for example
alter user 'root'#'localhost' identified with mysql_native_password by 'root';
Same issue occurred with me also, turned out my db username was wrong
Consider:
./mysqladmin -u root -p** '_redacted_'
Output (including typing the password):
Enter password:
mysqladmin: connect to server at 'localhost' failed error:
'Access denied for user 'root'#'localhost' (using password: YES)'
How can I fix this?
All solutions I found were much more complex than necessary and none worked for me. Here is the solution that solved my problem. There isn't any need to restart mysqld or start it with special privileges.
sudo mysql
-- for MySQL
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
-- for MariaDB
ALTER USER 'root'#'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('root');
With a single query we are changing the auth_plugin to mysql_native_password and setting the root password to root (feel free to change it in the query).
Now you should be able to log in with root. More information can be found in MySQL documentation or MariaDB documentation.
(Exit the MySQL console with Ctrl + D or by typing exit.)
Open and edit /etc/my.cnf or /etc/mysql/my.cnf, depending on your distribution.
Add skip-grant-tables under [mysqld]
Restart MySQL
You should be able to log in to MySQL now using the below command mysql -u root -p
Run mysql> flush privileges;
Set new password by ALTER USER 'root'#'localhost' IDENTIFIED BY 'NewPassword';
Go back to /etc/my.cnf and remove/comment skip-grant-tables
Restart MySQL
Now you will be able to login with the new password mysql -u root -p
None of the previous answers helped me with this problem, so here's the solution I found.
The relevant part:
In Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. This allows for some greater security and usability in many cases, but it can also complicate things when you need to allow an external program (e.g., phpMyAdmin) to access the user.
In order to use a password to connect to MySQL as root, you will need to switch its authentication method from auth_socket to mysql_native_password. To do this, open up the MySQL prompt from your terminal:
sudo mysql
Next, check which authentication method each of your MySQL user accounts use with the following command:
SELECT user,authentication_string,plugin,host FROM mysql.user;
Output
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | | auth_socket | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
In this example, you can see that the root user does in fact authenticate using the auth_socket plugin. To configure the root account to authenticate with a password, run the following ALTER USER command. Be sure to change password to a strong password of your choosing, and note that this command will change the root password you set in Step 2:
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
Then, run FLUSH PRIVILEGES which tells the server to reload the grant tables and put your new changes into effect:
FLUSH PRIVILEGES;
Check the authentication methods employed by each of your users again to confirm that root no longer authenticates using the auth_socket plugin:
SELECT user,authentication_string,plugin,host FROM mysql.user;
Output
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | *3636DACC8616D997782ADD0839F92C1571D6D78F | mysql_native_password | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
You can see in this example output that the root MySQL user now authenticates using a password. Once you confirm this on your own server, you can exit the MySQL shell:
exit
I tried many steps to get this issue corrected. There are so many sources for possible solutions to this issue that is is hard to filter out the sense from the nonsense. I finally found a good solution here:
Step 1: Identify the database version
mysql --version
You'll see some output like this with MySQL:
mysql Ver 14.14 Distrib 5.7.16, for Linux (x86_64) using EditLine wrapper
Or output like this for MariaDB:
mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1
Make note of which database and which version you're running, as you'll use them later. Next, you need to stop the database so you can access it manually.
Step 2: Stopping the database server
To change the root password, you have to shut down the database server beforehand.
You can do that for MySQL with:
sudo systemctl stop mysql
And for MariaDB with:
sudo systemctl stop mariadb
Step 3: Restarting the database server without permission checking
If you run MySQL and MariaDB without loading information about user privileges, it will allow you to access the database command line with root privileges without providing a password. This will allow you to gain access to the database without knowing it.
To do this, you need to stop the database from loading the grant tables, which store user privilege information. Because this is a bit of a security risk, you should also skip networking as well to prevent other clients from connecting.
Start the database without loading the grant tables or enabling networking:
sudo mysqld_safe --skip-grant-tables --skip-networking &
The ampersand at the end of this command will make this process run in the background so you can continue to use your terminal.
Now you can connect to the database as the root user, which should not ask for a password.
mysql -u root
You'll immediately see a database shell prompt instead.
MySQL Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
MariaDB Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>
Now that you have root access, you can change the root password.
Step 4: Changing the root password
mysql> FLUSH PRIVILEGES;
Now we can actually change the root password.
For MySQL 5.7.6 and newer as well as MariaDB 10.1.20 and newer, use the following command:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'new_password';
For MySQL 5.7.5 and older as well as MariaDB 10.1.20 and older, use:
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('new_password');
Make sure to replace new_password with your new password of choice.
Note: If the ALTER USER command doesn't work, it's usually indicative of a bigger problem. However, you can try UPDATE ... SET to reset the root password instead.
[IMPORTANT] This is the specific line that fixed my particular issue:
mysql> UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost';
Remember to reload the grant tables after this.
In either case, you should see confirmation that the command has been successfully executed.
Query OK, 0 rows affected (0.00 sec)
The password has been changed, so you can now stop the manual instance of the database server and restart it as it was before.
Step 5: Restart the Database Server Normally
The tutorial goes into some further steps to restart the database, but the only piece I used was this:
For MySQL, use:
sudo systemctl start mysql
For MariaDB, use:
sudo systemctl start mariadb
Now you can confirm that the new password has been applied correctly by running:
mysql -u root -p
The command should now prompt for the newly assigned password. Enter it, and you should gain access to the database prompt as expected.
Conclusion
You now have administrative access to the MySQL or MariaDB server restored. Make sure the new root password you choose is strong and secure and keep it in safe place.
After trying all others answers, this it what finally worked for me:
sudo mysql -- It does not ask me for any password
-- Then in MariaDB/MySQL console:
update mysql.user set plugin = 'mysql_native_password' where User='root';
FLUSH PRIVILEGES;
exit;
I found the answer in the blog post Solved: Error “Access denied for user ‘root’#’localhost’” of MySQL — codementor.tech (Medium).
For Ubuntu/Debian users
(It may work on other distributions, especially Debian-based ones.)
Run the following to connect as root (without any password)
sudo /usr/bin/mysql --defaults-file=/etc/mysql/debian.cnf
If you don't want to add --defaults-file each time you want to connect as root, you can copy /etc/mysql/debian.cnf into your home directory:
sudo cp /etc/mysql/debian.cnf ~/.my.cnf
And then:
sudo mysql
In my experience, if you run without sudo it will not work. So make sure your command is;
sudo mysql -uroot -p
For new Linux users this could be a daunting task. Let me update this with MySQL 8 (the latest version available right now is 8.0.12 as on 2018-09-12)
Open "mysqld.cnf" configuration file at "/etc/mysql/mysql.conf.d/".
Add skip-grant-tables to the next line of [mysql] text and save.
Restart the MySQL service as "sudo service mysql restart". Now your MySQL is free of any authentication.
Connect to the MySQL client (also known as mysql-shell) as mysql -u root -p. There is no password to be keyed in as of now.
Run SQL command flush privileges;
Reset the password now as ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPassword';
Now let's get back to the normal state; remove that line "skip-grant-tables" from "mysqld.cnf" and restart the service.
That's it.
In my case under Debian 10, the error
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
was solved by (good way)
sudo mysql -u root -p mysql
Bad way:
mysql -u root -p mysql
I did this to set my root password in the initial set up of MySQL in OS X. Open a terminal.
sudo sh -c 'echo /usr/local/mysql/bin > /etc/paths.d/mysql'
Close the terminal and open a new terminal.
And the following worked in Linux, to set the root password.
sudo /usr/local/mysql/support-files/mysql.server stop
sudo mysqld_safe --skip-grant-tables
(sudo mysqld_safe --skip-grant-tables: This did not work for me the first time. But on the second try, it was a success.)
Then log into MySQL:
mysql -u root
FLUSH PRIVILEGES;
Now change the password:
ALTER USER 'root'#'localhost' IDENTIFIED BY 'newpassword';
Restart MySQL:
sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server start
My Station here:
UBUNTU 21.04
PHP 5.6.40-57
MYSQL 5.7.37
let's config it
nano /etc/mysql/mysql.conf.d/mysqld.cnf
at the bottom, write this
skip-grant-tables
reload it
service mysql restart
In your MySQL Workbench, you can go to the left sidebar, under Management select "Users and Privileges", click root under User Accounts, in the right section click tab "Account Limits" to increase the maximum queries, updates, etc., and then click tab "Administrative Roles" and check the boxes to give the account access.
Ugh - nothing worked for me! I have a CentOS 7.4 machine running MariaDB 5.5.64.
I had to do this, right after installation of MariaDB from YUM;
systemctl restart mariadb
mysql_secure_installation
The mysql_secure_installation will take you through a number of steps, including "Set root password? [Y/n]". Just say "y" and give it a password. Answer the other questions as you wish.
Then you can get in with your password, using
mysql -u root -p
It will survive
systemctl restart mariadb
The Key
Then, I checked the /bin/mysql_secure_installation source code to find out how it was magically able to change the root password and none of the other answers here could. The import bit is:
do_query "UPDATE mysql.user SET Password=PASSWORD('$esc_pass') WHERE User='root';"
...It says SET Password=... and not SET authentication_string = PASSWORD.... So, the proper procedure for this version (5.5.64) is:
Log in using mysql -u root -p, using the password you already set.
Or, stop the database and start it with:
mysql_safe --skip-grant-tables --skip-networking &
From the mysql> prompt:
use mysql;
select host,user,password from user where user = 'root';
(observe your existing passwords for root).
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root' AND host = 'localhost';
select host,user,password from user where user = 'root';
flush privileges;
quit;
Kill the running mysqld_safe. Restart MariaDB. Log in as root: mysql -u -p. Use your new password.
If you want, you can set all the root passwords at once. I think this is wise:
mysql -u root -p
(login)
use mysql;
select host,user,password from user where user = 'root';
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root';
select host,user,password from user where user = 'root';
flush privileges;
quit;
This will perform updates on all the root passwords: i.e., for "localhost", "127.0.0.1", and "::1"
In the future, when I go to RHEL 8 or what have you, I will try to remember to check the /bin/mysql_secure_installation and see how the guys did it, who were the ones that configured MariaDB for this OS.
Use sudo to alter your password:
sudo mysql
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'insert_password';
Source: Phoenixnap - Access denied for user root localhost
Fix for macOS
Install MySQL from https://downloads.mysql.com/archives/community/ (8.x is the latest as on date, but ensure that the version is compatible with the macOS version)
Give password for root (let <root-password> be the password) during installation (don't forget to remember the password!)
Select Use Legacy Password Encryption option (that is what I had used and did not try for Use Strong Password Encryption option)
Search and open MySQL.prefPane (use search tool)
Select Configuration tab
Click Select option of Configuration File
Select /private/etc/my.cnf
From terminal open a new or existing file with name /etc/my.cnf (vi /etc/my.cnf) add the following content:
[mysqld]
skip-grant-tables
Restart mysqld as follows:
ps aux | grep mysql
kill -9 <pid1> <pid2> ... (grab pids of all MySQL related processes)
mysqld gets restarted automatically
Verify that the option is set by running the following from terminal:
ps aux | grep mysql
> mysql/bin/mysqld ... --defaults-file=/private/etc/my.cnf ... (output)
Run the following command to connect (let mysql-<version>-macos<version>-x86_64 be the folder where MySQL is installed. To grab the actual folder, run ls /usr/local/ and copy the folder name):
/usr/local/mysql-<version>-macos<version>-x86_64/bin/mysql -uroot -p<root-password>
If you are like me and all the information in previous answers failed, proceed to uninstall all versions of MySQL on your machine, search for all remaining MySQL files using the command sudo find / -name "mysql" and rm -rf every file or directory with the "mysql" name attached to it (you should skip files related to programming language libraries).
Now install a fresh version of MySQL and enjoy. NB: You will lose all your data so weigh your options first.
Sometimes a default password is set when you install it - as mentioned in the documentation. This can be confirmed by the following command.
sudo grep 'temporary password' /var/log/mysqld.log
It can happen if you don't have enough privileges.
Type su, enter the root password and try again.
After trying a lot with the following answer:
ALTER USER 'root'#'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('root');
And similar answers, my terminal was still throwing me the following error:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near...
So after researching on the web, this line solved my problem and let me change the root user password:
sudo mysqladmin --user=root password "[your password]"
windows :
cd \Ampps\mysql\bin :
mysql.exe -u root -pmysql
after mysql start (you can see shell like this mysql> )
use this query :
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
try again access with root root
If you reached this page via Google like I did and none of the previous solutions worked, what turned out to be the error was 100% foolishness on my end. I didn't connect to the server. Once connected everything was smooth sailing.
In case it helps to know my setup, I'm using Sequel Pro and am trying to connect to it with Node using the NPM package, mysql. I didn't think I needed to actually connect (other than run Sequel Pro), because I was doing that from my application already.
I was getting the same error while setting up the mysql-8 zip version. Finally, switched to installer version which worked seamlessly. During installation, there is a prompt to set up the root password. Once set, it works for sure.
According to MariaDB official documentation, in MariaDB 10.4.3 and later, the unix_socket authentication plugin is installed by default.
In order to disable it, and revert to the previous mysql_native_password authentication method, add line below in [mysqld] section of my.cnf file:
[mysqld]
unix_socket=OFF
And then run:
mysql_install_db --auth-root-authentication-method=normal
And then start mysqld
This command will then work fine:
mysqladmin -u root password CHANGEME
For additional information, see Configuring mysql_install_db to Revert to the Previous Authentication Method.
I was trying to leverage Docker desktop on Mac to get 5.7.35 running and this docker-compose.yml configuration allowed it to work:
In particular it was the addition of the line...
command: --default-authentication-plugin=mysql_native_password
...that did the trick
version: '3.3'
services:
mysql_db:
image: mysql:5.7
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: 'your_password'
ports:
- '3306:3306'
expose:
- '3306'
volumes:
- ~/your/volume/path:/var/lib/mysql
One thing to check is the from-host filter. It may be "localhost" by default. Are you trying to connect from a remote client? Change this to "%".
On Arch Linux
Package: mysql 8.0.29-1
What worked for me:
Edit my.cnf file, normally can be found at /etc/mysql/my.cnf and append this skip-grant-tables at the bottom/end of the file.
Restart mysql service by invoking sudo systemctl restart mysqld
Ensuring mysql service has started properly by invoking sudo systemctl status mysqld
Login to mysql using 'root' by invoking mysql -u root -p
Flush privileges by invoking flush privileges;
Create new user by CREATE USER 'root'#'localhost' IDENTIFIED BY 'rootpassword';
(If you plan to use this db with PHP), you should instead use this CREATE USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'rootpassword';
Check whether your changes have reflected in db by invoking the following in sequence:
use mysql;
SELECT User, password_last_changed FROM user;
Exit mysql console and comment/remove skip-grant-tables by editing my.cnf file (Refer to step 1 for the location)
Restart the mysql service (Refer to step 2 and step 3)
And that's all.
The '-p' argument doesn't expect a space between the argument name and value.
Instead of
./mysqladmin -u root -p 'redacted'
Use
./mysqladmin -u root -p'redacted'
Or just
./mysqladmin -u root -p
which will prompt you for a password.
Solution: Give up!
Hear me out. I spent about two whole days trying to make MySQL work to no avail, always stuck with permission errors, none of which were fixed by the answers to this question. It got to the point that I thought if I continued I'd go insane.
Out of patience for making it work, I sent the command to install SQLite, only using 450 KB, and it worked perfectly right from the word go.
If you don't have the patience of a saint, go with SQLite and save yourself a lot of time, effort, pain, and storage space..!
I installed phpmyadmin on my ubuntu server following these steps here:
https://www.rosehosting.com/blog/install-phpmyadmin-on-ubuntu-16-04/
I installed apache, php, mysql following these steps:
https://vijayasankarn.wordpress.com/2017/01/17/setting-lamp-stack-in-ubuntu-16-04-using-aws-ec2/
and when I goto login to http://myserver.com/phpmyadmin I get this error:
mysqli_real_connect(): (HY000/1045): Access denied for user
'root'#'localhost' (using password: YES)
What am I doing wrong? Am I missing a step that is not in the links above?
I have tried this:
mysql> USE mysql;
mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> exit;
$ service mysql restart
and this
mysql -u root -p
use mysql;
update user set plugin="" where user='root';
flush privilege;
This error can be fixed, the following command will reconfigure your phpMyAdmin credentials to gain access to the MYSQL DB:
sudo dpkg-reconfigure phpmyadmin
/!\ This will provide few interactive menus that will allow you to reconfigure the phpMyAdmin package with NEW credentials /!\
But you could also reconfigure it manually :
1 - Log into mysql as root
mysql -u root -p
2 - Make sure 'phpmyadmin' user exists :
SELECT User FROM mysql.user;
3 - Switch to the appropriate MYSQL DB :
use phpmyadmin;
4 - Set new password for the phpmyadmin user
UPDATE user SET password=PASSWORD('yourNewPassword') WHERE User='phpmyadmin';
sudo mysql -u root -p
USE mysql;
UPDATE user SET plugin='mysql_native_password' WHERE User ='root';
FLUSH PRIVILEGES;
exit;
sudo systemctl restart mysql
Check to see that you have actually set the root password in MySQL. You might find that when logged in as the root Linux user you can run
mysql -u root -p
and get access to your database no matter which password you specify, because the password hasn't actually been set. Use
ALTER USER 'root'#'localhost' IDENTIFIED BY 'PASSWORD'; FLUSH PRIVILEGES; EXIT;
to set your password, then try phpMyAdmin again.
Consider:
./mysqladmin -u root -p** '_redacted_'
Output (including typing the password):
Enter password:
mysqladmin: connect to server at 'localhost' failed error:
'Access denied for user 'root'#'localhost' (using password: YES)'
How can I fix this?
All solutions I found were much more complex than necessary and none worked for me. Here is the solution that solved my problem. There isn't any need to restart mysqld or start it with special privileges.
sudo mysql
-- for MySQL
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
-- for MariaDB
ALTER USER 'root'#'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('root');
With a single query we are changing the auth_plugin to mysql_native_password and setting the root password to root (feel free to change it in the query).
Now you should be able to log in with root. More information can be found in MySQL documentation or MariaDB documentation.
(Exit the MySQL console with Ctrl + D or by typing exit.)
Open and edit /etc/my.cnf or /etc/mysql/my.cnf, depending on your distribution.
Add skip-grant-tables under [mysqld]
Restart MySQL
You should be able to log in to MySQL now using the below command mysql -u root -p
Run mysql> flush privileges;
Set new password by ALTER USER 'root'#'localhost' IDENTIFIED BY 'NewPassword';
Go back to /etc/my.cnf and remove/comment skip-grant-tables
Restart MySQL
Now you will be able to login with the new password mysql -u root -p
None of the previous answers helped me with this problem, so here's the solution I found.
The relevant part:
In Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. This allows for some greater security and usability in many cases, but it can also complicate things when you need to allow an external program (e.g., phpMyAdmin) to access the user.
In order to use a password to connect to MySQL as root, you will need to switch its authentication method from auth_socket to mysql_native_password. To do this, open up the MySQL prompt from your terminal:
sudo mysql
Next, check which authentication method each of your MySQL user accounts use with the following command:
SELECT user,authentication_string,plugin,host FROM mysql.user;
Output
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | | auth_socket | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
In this example, you can see that the root user does in fact authenticate using the auth_socket plugin. To configure the root account to authenticate with a password, run the following ALTER USER command. Be sure to change password to a strong password of your choosing, and note that this command will change the root password you set in Step 2:
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
Then, run FLUSH PRIVILEGES which tells the server to reload the grant tables and put your new changes into effect:
FLUSH PRIVILEGES;
Check the authentication methods employed by each of your users again to confirm that root no longer authenticates using the auth_socket plugin:
SELECT user,authentication_string,plugin,host FROM mysql.user;
Output
+------------------+-------------------------------------------+-----------------------+-----------+
| user | authentication_string | plugin | host |
+------------------+-------------------------------------------+-----------------------+-----------+
| root | *3636DACC8616D997782ADD0839F92C1571D6D78F | mysql_native_password | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
+------------------+-------------------------------------------+-----------------------+-----------+
4 rows in set (0.00 sec)
You can see in this example output that the root MySQL user now authenticates using a password. Once you confirm this on your own server, you can exit the MySQL shell:
exit
I tried many steps to get this issue corrected. There are so many sources for possible solutions to this issue that is is hard to filter out the sense from the nonsense. I finally found a good solution here:
Step 1: Identify the database version
mysql --version
You'll see some output like this with MySQL:
mysql Ver 14.14 Distrib 5.7.16, for Linux (x86_64) using EditLine wrapper
Or output like this for MariaDB:
mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1
Make note of which database and which version you're running, as you'll use them later. Next, you need to stop the database so you can access it manually.
Step 2: Stopping the database server
To change the root password, you have to shut down the database server beforehand.
You can do that for MySQL with:
sudo systemctl stop mysql
And for MariaDB with:
sudo systemctl stop mariadb
Step 3: Restarting the database server without permission checking
If you run MySQL and MariaDB without loading information about user privileges, it will allow you to access the database command line with root privileges without providing a password. This will allow you to gain access to the database without knowing it.
To do this, you need to stop the database from loading the grant tables, which store user privilege information. Because this is a bit of a security risk, you should also skip networking as well to prevent other clients from connecting.
Start the database without loading the grant tables or enabling networking:
sudo mysqld_safe --skip-grant-tables --skip-networking &
The ampersand at the end of this command will make this process run in the background so you can continue to use your terminal.
Now you can connect to the database as the root user, which should not ask for a password.
mysql -u root
You'll immediately see a database shell prompt instead.
MySQL Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
MariaDB Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>
Now that you have root access, you can change the root password.
Step 4: Changing the root password
mysql> FLUSH PRIVILEGES;
Now we can actually change the root password.
For MySQL 5.7.6 and newer as well as MariaDB 10.1.20 and newer, use the following command:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'new_password';
For MySQL 5.7.5 and older as well as MariaDB 10.1.20 and older, use:
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('new_password');
Make sure to replace new_password with your new password of choice.
Note: If the ALTER USER command doesn't work, it's usually indicative of a bigger problem. However, you can try UPDATE ... SET to reset the root password instead.
[IMPORTANT] This is the specific line that fixed my particular issue:
mysql> UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost';
Remember to reload the grant tables after this.
In either case, you should see confirmation that the command has been successfully executed.
Query OK, 0 rows affected (0.00 sec)
The password has been changed, so you can now stop the manual instance of the database server and restart it as it was before.
Step 5: Restart the Database Server Normally
The tutorial goes into some further steps to restart the database, but the only piece I used was this:
For MySQL, use:
sudo systemctl start mysql
For MariaDB, use:
sudo systemctl start mariadb
Now you can confirm that the new password has been applied correctly by running:
mysql -u root -p
The command should now prompt for the newly assigned password. Enter it, and you should gain access to the database prompt as expected.
Conclusion
You now have administrative access to the MySQL or MariaDB server restored. Make sure the new root password you choose is strong and secure and keep it in safe place.
After trying all others answers, this it what finally worked for me:
sudo mysql -- It does not ask me for any password
-- Then in MariaDB/MySQL console:
update mysql.user set plugin = 'mysql_native_password' where User='root';
FLUSH PRIVILEGES;
exit;
I found the answer in the blog post Solved: Error “Access denied for user ‘root’#’localhost’” of MySQL — codementor.tech (Medium).
For Ubuntu/Debian users
(It may work on other distributions, especially Debian-based ones.)
Run the following to connect as root (without any password)
sudo /usr/bin/mysql --defaults-file=/etc/mysql/debian.cnf
If you don't want to add --defaults-file each time you want to connect as root, you can copy /etc/mysql/debian.cnf into your home directory:
sudo cp /etc/mysql/debian.cnf ~/.my.cnf
And then:
sudo mysql
In my experience, if you run without sudo it will not work. So make sure your command is;
sudo mysql -uroot -p
For new Linux users this could be a daunting task. Let me update this with MySQL 8 (the latest version available right now is 8.0.12 as on 2018-09-12)
Open "mysqld.cnf" configuration file at "/etc/mysql/mysql.conf.d/".
Add skip-grant-tables to the next line of [mysql] text and save.
Restart the MySQL service as "sudo service mysql restart". Now your MySQL is free of any authentication.
Connect to the MySQL client (also known as mysql-shell) as mysql -u root -p. There is no password to be keyed in as of now.
Run SQL command flush privileges;
Reset the password now as ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPassword';
Now let's get back to the normal state; remove that line "skip-grant-tables" from "mysqld.cnf" and restart the service.
That's it.
In my case under Debian 10, the error
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
was solved by (good way)
sudo mysql -u root -p mysql
Bad way:
mysql -u root -p mysql
I did this to set my root password in the initial set up of MySQL in OS X. Open a terminal.
sudo sh -c 'echo /usr/local/mysql/bin > /etc/paths.d/mysql'
Close the terminal and open a new terminal.
And the following worked in Linux, to set the root password.
sudo /usr/local/mysql/support-files/mysql.server stop
sudo mysqld_safe --skip-grant-tables
(sudo mysqld_safe --skip-grant-tables: This did not work for me the first time. But on the second try, it was a success.)
Then log into MySQL:
mysql -u root
FLUSH PRIVILEGES;
Now change the password:
ALTER USER 'root'#'localhost' IDENTIFIED BY 'newpassword';
Restart MySQL:
sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server start
My Station here:
UBUNTU 21.04
PHP 5.6.40-57
MYSQL 5.7.37
let's config it
nano /etc/mysql/mysql.conf.d/mysqld.cnf
at the bottom, write this
skip-grant-tables
reload it
service mysql restart
In your MySQL Workbench, you can go to the left sidebar, under Management select "Users and Privileges", click root under User Accounts, in the right section click tab "Account Limits" to increase the maximum queries, updates, etc., and then click tab "Administrative Roles" and check the boxes to give the account access.
Ugh - nothing worked for me! I have a CentOS 7.4 machine running MariaDB 5.5.64.
I had to do this, right after installation of MariaDB from YUM;
systemctl restart mariadb
mysql_secure_installation
The mysql_secure_installation will take you through a number of steps, including "Set root password? [Y/n]". Just say "y" and give it a password. Answer the other questions as you wish.
Then you can get in with your password, using
mysql -u root -p
It will survive
systemctl restart mariadb
The Key
Then, I checked the /bin/mysql_secure_installation source code to find out how it was magically able to change the root password and none of the other answers here could. The import bit is:
do_query "UPDATE mysql.user SET Password=PASSWORD('$esc_pass') WHERE User='root';"
...It says SET Password=... and not SET authentication_string = PASSWORD.... So, the proper procedure for this version (5.5.64) is:
Log in using mysql -u root -p, using the password you already set.
Or, stop the database and start it with:
mysql_safe --skip-grant-tables --skip-networking &
From the mysql> prompt:
use mysql;
select host,user,password from user where user = 'root';
(observe your existing passwords for root).
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root' AND host = 'localhost';
select host,user,password from user where user = 'root';
flush privileges;
quit;
Kill the running mysqld_safe. Restart MariaDB. Log in as root: mysql -u -p. Use your new password.
If you want, you can set all the root passwords at once. I think this is wise:
mysql -u root -p
(login)
use mysql;
select host,user,password from user where user = 'root';
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root';
select host,user,password from user where user = 'root';
flush privileges;
quit;
This will perform updates on all the root passwords: i.e., for "localhost", "127.0.0.1", and "::1"
In the future, when I go to RHEL 8 or what have you, I will try to remember to check the /bin/mysql_secure_installation and see how the guys did it, who were the ones that configured MariaDB for this OS.
Use sudo to alter your password:
sudo mysql
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'insert_password';
Source: Phoenixnap - Access denied for user root localhost
Fix for macOS
Install MySQL from https://downloads.mysql.com/archives/community/ (8.x is the latest as on date, but ensure that the version is compatible with the macOS version)
Give password for root (let <root-password> be the password) during installation (don't forget to remember the password!)
Select Use Legacy Password Encryption option (that is what I had used and did not try for Use Strong Password Encryption option)
Search and open MySQL.prefPane (use search tool)
Select Configuration tab
Click Select option of Configuration File
Select /private/etc/my.cnf
From terminal open a new or existing file with name /etc/my.cnf (vi /etc/my.cnf) add the following content:
[mysqld]
skip-grant-tables
Restart mysqld as follows:
ps aux | grep mysql
kill -9 <pid1> <pid2> ... (grab pids of all MySQL related processes)
mysqld gets restarted automatically
Verify that the option is set by running the following from terminal:
ps aux | grep mysql
> mysql/bin/mysqld ... --defaults-file=/private/etc/my.cnf ... (output)
Run the following command to connect (let mysql-<version>-macos<version>-x86_64 be the folder where MySQL is installed. To grab the actual folder, run ls /usr/local/ and copy the folder name):
/usr/local/mysql-<version>-macos<version>-x86_64/bin/mysql -uroot -p<root-password>
If you are like me and all the information in previous answers failed, proceed to uninstall all versions of MySQL on your machine, search for all remaining MySQL files using the command sudo find / -name "mysql" and rm -rf every file or directory with the "mysql" name attached to it (you should skip files related to programming language libraries).
Now install a fresh version of MySQL and enjoy. NB: You will lose all your data so weigh your options first.
Sometimes a default password is set when you install it - as mentioned in the documentation. This can be confirmed by the following command.
sudo grep 'temporary password' /var/log/mysqld.log
It can happen if you don't have enough privileges.
Type su, enter the root password and try again.
After trying a lot with the following answer:
ALTER USER 'root'#'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('root');
And similar answers, my terminal was still throwing me the following error:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near...
So after researching on the web, this line solved my problem and let me change the root user password:
sudo mysqladmin --user=root password "[your password]"
windows :
cd \Ampps\mysql\bin :
mysql.exe -u root -pmysql
after mysql start (you can see shell like this mysql> )
use this query :
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
try again access with root root
If you reached this page via Google like I did and none of the previous solutions worked, what turned out to be the error was 100% foolishness on my end. I didn't connect to the server. Once connected everything was smooth sailing.
In case it helps to know my setup, I'm using Sequel Pro and am trying to connect to it with Node using the NPM package, mysql. I didn't think I needed to actually connect (other than run Sequel Pro), because I was doing that from my application already.
I was getting the same error while setting up the mysql-8 zip version. Finally, switched to installer version which worked seamlessly. During installation, there is a prompt to set up the root password. Once set, it works for sure.
According to MariaDB official documentation, in MariaDB 10.4.3 and later, the unix_socket authentication plugin is installed by default.
In order to disable it, and revert to the previous mysql_native_password authentication method, add line below in [mysqld] section of my.cnf file:
[mysqld]
unix_socket=OFF
And then run:
mysql_install_db --auth-root-authentication-method=normal
And then start mysqld
This command will then work fine:
mysqladmin -u root password CHANGEME
For additional information, see Configuring mysql_install_db to Revert to the Previous Authentication Method.
I was trying to leverage Docker desktop on Mac to get 5.7.35 running and this docker-compose.yml configuration allowed it to work:
In particular it was the addition of the line...
command: --default-authentication-plugin=mysql_native_password
...that did the trick
version: '3.3'
services:
mysql_db:
image: mysql:5.7
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: 'your_password'
ports:
- '3306:3306'
expose:
- '3306'
volumes:
- ~/your/volume/path:/var/lib/mysql
One thing to check is the from-host filter. It may be "localhost" by default. Are you trying to connect from a remote client? Change this to "%".
On Arch Linux
Package: mysql 8.0.29-1
What worked for me:
Edit my.cnf file, normally can be found at /etc/mysql/my.cnf and append this skip-grant-tables at the bottom/end of the file.
Restart mysql service by invoking sudo systemctl restart mysqld
Ensuring mysql service has started properly by invoking sudo systemctl status mysqld
Login to mysql using 'root' by invoking mysql -u root -p
Flush privileges by invoking flush privileges;
Create new user by CREATE USER 'root'#'localhost' IDENTIFIED BY 'rootpassword';
(If you plan to use this db with PHP), you should instead use this CREATE USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'rootpassword';
Check whether your changes have reflected in db by invoking the following in sequence:
use mysql;
SELECT User, password_last_changed FROM user;
Exit mysql console and comment/remove skip-grant-tables by editing my.cnf file (Refer to step 1 for the location)
Restart the mysql service (Refer to step 2 and step 3)
And that's all.
The '-p' argument doesn't expect a space between the argument name and value.
Instead of
./mysqladmin -u root -p 'redacted'
Use
./mysqladmin -u root -p'redacted'
Or just
./mysqladmin -u root -p
which will prompt you for a password.
Solution: Give up!
Hear me out. I spent about two whole days trying to make MySQL work to no avail, always stuck with permission errors, none of which were fixed by the answers to this question. It got to the point that I thought if I continued I'd go insane.
Out of patience for making it work, I sent the command to install SQLite, only using 450 KB, and it worked perfectly right from the word go.
If you don't have the patience of a saint, go with SQLite and save yourself a lot of time, effort, pain, and storage space..!
