Problems:- Whenever I try to select all tables in a database the connection is just lost and unknown error is given by the server to the browser and the browser just reloads with its own error page stating that the server gave unknown error. (This is in phpmyadmin)
I tried to solve this by adding max_allowed_packet to my.cnf first time and restarting mysql , and then adding it by mysql --max_allowed_packet=32M and restarting mysql, but the changes were not reflected in mysql. The limit was still set to default which is 16M.
Can anyone please suggest possible solutions for this
First I'll assume you are using apache
log in to your server
run the command
tail -f /var/log/httpd/error_log <== may be different depending on your install
then run the same query in phpmyadmin
watch the output of the tail command and see what it says.
restart server and try again by using command reboot

I've tried many methods but it could not work. Apache is working fine but MySQL service is not able to start. Wamp icon is orange and showing only 1 of 3 services running.
I have tried all points mentioned in MySQL service not starting on WAMP?
After so much exploring, it is rectified now. The my.ini file inside the Windows folder was the real problem. It is conflicting with the WAMP mysql my.ini. Now it is working fine after deleting that file from the Windows folder.
after lots of struggling, I found the solution in this answer
for me, the reason for this issue was the wrong config data was cached for mysql so did this:
I tried going to: C:\wamp64\bin\mysql\mysql5.7.24\data and deleted the
following:
auto.cnf, xxxxxxxxx.err, xxxxxxxxx.pid, ib_logfile0 and ib_logfile1
But I left the ibdata1 alone as it references all local databases.(dont delete that at all!) I
then restarted wamp and it worked like a charm.
Delete the my.ini file inside the folder work
Go to cmd and run 'netstat /a' to get a list of all the ports running.
Check to see if TCP 0.0.0.0:3006 is on the list. On mine, it was not and 0.0.0.0:3008 was on the list instead.
To verify the database is in fact running:
Change directory to the folder holding the mysql version I expected to be running. Then I attempted to login with command line to the mysql database I instantiated with phpMyAdmin... using 'mysql -u yourloginId -p yourDataBaseName'
Hit enter and then enter your pass word. If you did not setup a password... skip the '-p'.
If you database is running you'll get a bunch of info related to it and changes the prompt to 'mysql'.... type in 'quit' and hit enter to exit out. Then you are done with cmd.
Since the database is running and WAMP is using ports in the 3000 range, then I assumed that 3008 is the correct port. Go to the WAMP icon click on it... go to php then php.ini and edit it. Do a find on 3006... and you will likely find it as mysql port... change it to the port actually running mysql... for me it was 3008. Save it and restart WAMP... Issue should be resolved.
going to C:\wamp64\bin\mysql*yourmysqlversion* you should find my.ini
After deleting that file you should be fine. Be sure to use your Wamp testing tools in wamp settings to test the ports for Mysql/Maria DB and Apache. Microsoft IIS is a common culprit for not making all services run.
All of a sudden I am encountering this problem on my mac. I cant start my MySQL Database. I can only start my ProFTPD and Apache Web Server.
This is the application log:
Starting all servers...
Starting MySQL Database...
Starting Apache Web Server...
/Applications/XAMPP/xamppfiles/apache2/scripts/ctl.sh : httpd started
Starting ProFTPD...
Checking syntax of configuration file
/Applications/XAMPP/xamppfiles/proftpd/scripts/ctl.sh : proftpd started
I have even did some research through stackoverflow. First i tried to end the process through my activity monitor by i couldnt find the keyword sql on the filter search area. The second method i tried was adding the unset DYLD_LIBRARY_PATH
but that didnt even worked for me.
Can i know how to solve this problem. Helps would be really appreciated. Thank you
#1. Open XAMPP Installation Directory
#2. Open "etc" Folder
#3. Find "my.cnf" file and open it in any text editor
#4. Change Port from 3306 to 3307 (if you have installed skype or other apps)
#5. Add "innodb_force_recovery=1" under "myisam_sort_buffer_size=8M"
#6. Save "my.cnf" file
#7. Restart Mysql Server By Your Terminal by command:
"sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start"
You Get A message "Starting MySQL SUCCESS! "
For me, Xampp Control panel was not launching, and in Stackoverflow some where it was mentioned to add Read / Write for every one on every file of xampp, when I did that. It allowed me to launch xampp control panel but mysql was not starting.
Later I debuged and found that /Applications/XAMPP/xamppfiles/etc/my.cnf should not be writeable by everyone, mysql will ignore my.cnf if it is for everyone. I changed the permission to read only for this file, and able to start mysql server
I just solve the answer by going to the activity monitor and search for sql under all process and terminate it. then i restart my mac and now my sql database is working great for me.
I Know this post was originally posted last year, but I just had the same problem and I found the solution for me. So here it is, just in case this can help somebody else.
I tried all the suggestions I found online, including trying to terminate MySQL on the activity monitor, but then I realized that when you download/upgrade XAMPP - MySQL, the option to automatically start MySQLserver on Startup is ON. You need to turn it off. Here is what you do:
Go System Preferences and click on the Mysql icon, You should get this window:
Uncheck that option. You will be asked for your password. After you are done with that, restart your computer and the problem should be fixed.
I hope that help somebody who is as confused as I was. lol ✌🏼
Xampp Control Panel> Manage Server> Mysql Database > Configure > change the port from 3306 to 3307
At least it worked for me in mac.
For me using macOS Catalina, I had to delete this 2 files then quit and restart the manager-osx:
MyName-MacBook-Pro.local.err
tc.log
The folder path is this: /Applications/XAMPP/xamppfiles/var
Note: the 2 files were automatically regenerated after I start and Apache and MySQL
If mysql is not starting in xampp, it might be a port conflict issue. Mysql run by default on port 3306. you need to check if another application is occupying that port. use following command to check app occupying a port
lsof -nP -i4TCP:3306
if you find an application occupying that port, stop the application and restart xampp. As an alternative, you can go to php.ini file or click configure in the dropdown and change the mysql port to 3307
I spent whole day trying to resolve this issue. Changing the port no from 3306 to 3307 worked for me. Simply open the configure module and change the port number. Hope it works for you.
In case this may help. I followed all the steps above still nothing worked for me. And I follow this article MySQL database won't start in xampp and it worked. what is says is:
Steps
Open terminal and type
sudo su
and then put in your password
Then type
ps aux | grep mysql
You will need to get the process id of mysql. There should be number near the top, something like 739 or 8827 (in my case I got 74689, just look after mysql or _mysql process id)
Kill the process using
kill -9 {process id}
this should look something like this: kill -9 739
Restart MySQL in manager-osx
If any of the above don’t work, This should work:
sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start
I tried the suggested solutions above however none worked for me. So I uninstalled XAMPP and then reinstalled it and so now MySQL server starts up ok.
This is driving me crazy! I have MySQL preference pane on my Mac OS X Lion, and also start and stop it from Terminal. mysql works from terminal and I can connect to databases, but when I do it from PHP source code it doesn't connect. It worked last night but now it doesn't and I dont know why. Here is a few details:
I'm telling php.ini to look for mysql.sock in the correct directory
I have also set the socket variable in my.cnf of mysql to the correct path.
Just to be sure, I have created a symlink in the default directory for mysql socket (/tmp/mysql.sock) to link to the socket file in /var/tmp/mysql.sock.
When I have stopped MySQL from the preference pane, and I try to start it from Terminal, it says 'SUCCESS!' but I can't use it with the command mysql in Terminal.
Can anyone get anything out from this messed up situation??
Answering my own question:
OK so I don't know why but I had discrepancies in the configuration. Even though I had set the socket variable in my.cnf file, when I started mysql server, it always looked for a different location for the socket.
my.cnf
[mysqld]
socket=/var/tmp/mysql.sock
[client]
socket=/var/tmp/mysql.sock
and I was still getting the error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2). Note how it still looks for /tmp/mysql.sock?
After finding this link, I realised that my mysql server was never reading my config file in /usr/local/mysql/my.cnf.
This is what I got from mysqladmin command:
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf
Solution: I created a symlink in my home folder
ln -s /usr/local/mysql/my.cnf ~/.my.cnf
And yess! Problem solved :)
i just installed xampp on my pc windows 7 64bit,it seems everything was successfully installed but when i click on phpMyAdmin i get an error like this on the image below
Check to see if MySQL is started and not just Apache/PHP.
Try disabling your firewall. If that works, look into properly creating a firewall rule for it.
In the future, these questions would be better posed in other venues (consider serverfault.com or webmasters.stackexchange.com)
Open the command line and type in:
mysql -u root -p
Enter the password (if no password set, leave off -p switch).
If you can get in, at least you know MySQL is running properly. So the fault is not there.
Check phpmyadmin's config.inc.php file. It could have wrong login mechanism set, the wrong username/password set, or is using a port number other than 3306 (default for MySQL).
Also consider trying some of the other wamp packages such as : WampServer, UniformServer, ZWamp, WampDeveloper (commercial)...
http://en.wikipedia.org/wiki/Comparison_of_WAMPs
You might have better luck there. Just make sure to uninstall, delete, and reboot first.
I just reinstalled Mac Os X 10.6.2 and had to reinstall/update my MySQL server.
I run phpMyAdmin inside my localhost and I used to be able to login without a hitch.
Since the updated (latest version MySQL 5.1.45 & PMA 3.3.1) versions I only get the following error when trying to login with phpMyAdmin:
phpMyAdmin - Error
Cannot start session without errors, please check errors given in your PHP
and/or webserver log file and configure your PHP installation properly.
The only thing I noticed is that mcrypt cannot be loaded (this has always been the case, no idea what to do to install this..) but this has never been a problem before.
If anyone know what to do here that would be really appreciated.
Thanks for reading,
Jannis
PS: The MySQL server itself is running and I am able to login with as root user via the MySQL Administrator.app
Well setting log_errors to on would bring error messages to the web-server's error_log. To do so you can use an .htaccess file placed in your web root with
php_value log_errors = 1
in it. It can be not worked but there is some other ways too. You can edit your php.ini for example and restart your server after it.
Without error message it's hard to guess what is really happened. there can be something wrong with session save path or other settings
This happened to me when I changed my password from within PHPMyAdmin. The solution was simple. Clear the browser cache and try to login again. You should be good to go.
Old thread I know, but I've been struggling all day with this.
I'm on MacOSX Lion. Unfortunately, I've been struggling with the same issue all day. In my case however, I was not getting an errors in the php error_log. So I was clueless as to what was happening. I finally found a setting in phpMyAdmin's config.inc.php and used it like so:
$cfg['Error_Handler']['display'] = true;
After this I was able to see in the browser itself what the problem was with permissions on the folder specified in session.save_path (./tmp which is a symlink to /private/tmp on mac).
However, I'd like to add the setting a 777 to the session.save_path folder may not be the right thing to do. I have done the following which seems safer:
owner: root (default)
group: _www (sudo chgrp _www /private/tmp)
Then allow the group to read, write and execute using:
sudo chmod g+rwx /private/tmp
Prevent others from reading, writing or executing in this folder:
sudo chmod o-rwx /private/tmp
I too upgraded to 10.6, actually I got a new mac and migrated my system over, then I installed phpmyadmin 3.4.2 and was getting messages about not being able to login as well as message about needing mcrypt. I re-installed PHP, now I'm running PHP Version 5.3.6.
I had Navicat on my system and was able to log into mysql database without issue. I tried resetting my mysql password, but that would not take. Not sure why. I had no valuable data so I re-installed MySQL, now I'm running MYSQL 5.5.13.
Still I could not login with phpMyAdmin - however thanks to new MySQL I was no longer seeing message about needing encyption, but I was getting a #1045 error on phpmyadmin. I guess it was telling me I had wrong password. Actually I had never set a password! I guess phpMyAdmin didn't like that as it would not allow me to login without a pw. (as you can see from this post I am not well versed in linux/unix, but I am one persistent fellow! this took me three nights.)
I entered these in Terminal to set a password, then phpmyadmin worked!
1) Need to first stop the MYSQL server, enter this in Terminal, then hit enter:
/etc/rc.d/init.d/mysql stop
2) Then set a password or new password. Needless to say replace 'whatever…" with your password of choice by entering this line in Terminal, and hit enter.
UPDATE mysql.user SET Password=PASSWORD('whateverfornew') WHERE User='root';
3) Now flush the privileges by entering this line in Terminal, and hit enter:
FLUSH PRIVILEGES;
4) Now restart MySQL by entering this line in Terminal, and hit enter:
/etc/rc.d/init.d/mysql start
5) Now login to your phpmyadmin with username "root" and your new password.
Yep, I know this is rudimentary and I have no idea if I am following best practices but for those of us who are new to Mac / Unix and want to get phpmyadmin, mysql etc running this worked for me. Personally I found a lot of forums but most already assume that reader is comfortable using terminal and Unix commands…which I am not - I just wanted a working development zone.
