I'm trying to get a wordpress local install working on my Mac.
I've recently set up a database, username and password using the MySQL client as per the instructions in the wordpress codex. That part is ok.
When I go to the local site on my computer I'm prompted by wordpress to set up the wp-config.php file. Putting in the same details that definitely work with the MySQL client returns an error.
Manually updating these details in the 'wp-config-sample.php' file and renaming it as 'wp-config.php' also doesn't work - I'm now greeted with a big bold message: "Error establishing a database connection".
From what I can gather, php and mysql are not communicating with each other properly.
I've changed the apache 2 configuration file found in 'etc/apache2/httpd.conf' and uncommented the line which loads the php5 module: LoadModule php5_module libexec/apache2/libphp5.so
and restarted the apache server. This has still not fixed my problem. I'm stuck on what to do next... help appreciated please!
It's been fixed now.
php was looking in the wrong place for the mysql.sock file, and couldn't communicate with the mysql database, meaning wordpress couldn't be set up.
On the command line I typed
ps aux | grep mysql
to bring up as much info about mysql that I could. From this I saw that the mysql socket on my computer is being used at /tmp/mysql.sock
Meanwhile, in the "wp-config.php" file, I changed the line define('WP_DEBUG', false); to define('WP_DEBUG', true); and refreshed my web browser that was showing my localhost setup. This now said a lot more info than "Error establishing a database connection" - infact I could see that the mysql.sock was not configured correctly at all.
Creating a 'phpinfo.php' file with just the single line of code <?php phpinfo(); ?> was the pivotal turning point for me.
Putting that 'phpinfo.php' file in my localhost directory and then viewing it from my web browser not only definitely confirmed that the mysql.sock file was not configured properly, but it also showed where the configurations were being loaded from on my machine: '/private/etc/php.ini'
The next thing I did was open up the 'php.ini' file in a text editor and doing a quick find and replace to update the correct location of mysql.sock.
Finally, a restart of the local apache server needed to be done to fully update all the new settings that I'd been fiddling about with.
sudo apachectl restart
Now everything works fine!
The Error-Message "Error establishing a database connection" indicates clearly, that the php-script can not establish the connection. This can have one of the following reasons:
Your host in the wp-config.php is not correct.
The mysql-server does not listen on that host
The user you set up in the mysql has no privileges to connect the way you are trying
The firewall blocks the access of the php-script to your mysql-host
Try to connect the database with the same settings of your wordpress using Sequel Pro (or any other GUI to connect a mysql database). If the connection works, the problem 2. and 3. isn't your problem.
Look in your firewall-log to make sure 4. is also not your problem.
If all problems are excluded (even 1. after a final check), try to run something like phpMyAdmin to connect your database, to make sure your php-installation has the needed drivers.

Please do not close this question, it's not a duplicate and the suggested link explaining how to use quotes on MySQL does nothing for me since this problem is inside a WP script. Thanks
I’m trying to install WP 5.4.1 on a clean Windows 2019 Server virtual machine.
I didn’t use Microsoft Web Platform Installer since it download old versions of WP / MySQL and PHP, so I’m trying to install from scratch.
Here are the steps I’ve taken:
Downloaded and Installed latest PHP 7.4.5, non thread safe version
and installed it
renamed php.ini-production to php.ini
Edited php.ini to:
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300
extesion=mysqli (removed the semicolon here since PHP needs this driver to connect to MySQL8)
In IIS I created the *.php mapping and added default.php and index.php
Created the dummy phpinfo.php file and tested on IIS, all working correctly and phpinfo() shows data
Downloaded MySQL 8.0.20 and installed with the following options:
Server only
Standalone
Server computer
For the authentication method I choose ‘Use Stron password encryption’ as suggested by the PHP installer
added MySQL BIN folder to path environment variable
opened %PROGRAMDATA%\MySQL\MySQL Server 8.0\my.ini and disabled sha2 and enable native_password:
;default_authentication_plugin=caching_sha2_password
default_authentication_plugin=mysql_native_password
created a new database for WP, called wp1 (in MySQL 8, the ‘one liner’ to create the user and grant access at the same time doesn’t work, so we need to do it in 2 lines)
mysql -u root -p
create database wp1;
CREATE USER ‘wp1’#’%’ IDENTIFIED BY ‘password’;
GRANT ALL PRIVILEGES ON wp1.* TO ‘wp1’#’%’;
FLUSH PRIVILEGES;
EXIT
created the folder C:\intepub\wwroot\wp1 and give full access to IUSR and Users windows groups so WP can write the config files
In IIS, right click on the Default Web Site and click on Add Application pointing to the new wp1 folder
navigate to localhost/wp1 to start WP installation
So after selecting the language and entering the DB info, I get this error
WordPress database error Unknown column ‘wp_’ in ‘field list’ for query SELECT wp_
After hours fighting with this, here’s what I found:
the error came from the DB, not WP.
tried with both wp1 and root users during the installation
tried with both localhost and 127.0.0.1 during the installation
the error generates in setup-config.php file, line 315 $wpdb->query("SELECT $prefix")
seems the problem is that what arrives at MySQL is the string select wp_ insted of select 'wp_' (note the missing quotes)
If I go to MySQL and execute select wp_ I get the exact same error
So the issue seems to be related to how MySQL 8.0 is handling quotes in the query it receives from WP installer…
I restored a snapshot just before installing MySQL 8.0.20 and this time, instead of
Use Strong Password Encryption for Authentication
I selected
Use Legacy Authentication Method (Retain MySQL 5.x Compatibility) but the error is still the same
Before answering, please consider:
I’m looking to solve the issue, not to start a discussion whatever I should use MySQL 5.x instead of MySQL 8.x
Yes, the connection to the database is Ok, that’s not the problem, please read all the my post
Yes, wp-config is being written with the correct values
Even tough I saw many messages with this same error on the WP forum, they normally have no answer, or the answer don’t make any sense (like asking to OP to check the DB credentials and write access to the WP folder), still I posted on the WP forum, but I no answer yet.
Sorry for my poor formatting!
Can anyone please help?
Finally found the issue...
TLDR; edit your php.ini and make sure you have both:
display_errors = On
error_log = php_errors.log
Setting error_log solves the issue... I guess that when error_log has no value (default configuration), PHP decides to send the error back to the calling program, resulting in the error message column 'wp_' in 'field list' during the WP installation.

I just deleted lines 317 to 322 in wp-admin\setup-config.php re-ran the setup and it all worked fine.
Might not be the right solution but the only thing that worked for me.
This was for WP 5.5.3, previous versions I had no issues downloading and installing
This error is possible if WordPress version doesn't support server's PHP version.
In my case I recently installed the latest XAMPP with PHP 8.1.1 and had to downgrade PHP to 8.0.14 in order for WordPress 5.8.2/5.8.3 to be installed and work properly.
I just deleted lines 317 to 322 in wp-admin\setup-config.php re-ran the setup and it all worked fine.

Same for me on version 5.6.2 when trying to install a second site using the same database so needed new table prefix
None of the above solutions is worked for my case. Because I have already installed Mysql workbench on my windows machine. I stopped the already running mysql server, I have followed the below mentioned steps.
Open command prompt, then navigate to the following path
C:\Program Files\MySQL\MySQL Server 8.0\
Then ran the following command
mysqladmin -u root -p shutdown
After that I restarted the apache and mysql on xampp server it is working fine.
I found a solution, for me the problem was in php folder (exactly "php.ini" file), so to get the standard settings I just installed windows server 2019 in VMWare then installed "php 7.4" using web platform, then I copied the PHP folder from VMWare "C:\Program Files (x86)\PHP\v7.4" to my PC (windows10), then I download "wordpress5.8.2", and "mysql8.0.1", after installing mysql and creating DB for wordpress(just create DB) and setup the IIS in my windows10, I ran localhost and every thing working good and wordpress installed without any errors.
So try to get the php.ini that installed with web platform and overwrite it on your php folder and run, if it does not work try to copy the whole php folder and try again, I tried this with php 8.0 but have many errors.
I just set up XAMPP and, when I start the Apache localhost, it displays all of these errors when I search "localhost/phpmyadmin"
I am very new to this (just downloaded XAMPP) and I watched this tutorial: https://www.youtube.com/watch?v=hqfIksHKPPg on setting it up (I didn't install phpmyadmin since it was already installed with XAMPP)
I edited the notepad text files as stated in the video, but instead of a login, I get all of the error messages shown in the above picture...
I also opened config.inc.php and edited the line:
['Servers'][$i]['(MySQL root password)'] = '';$cfg
so it matched MySQL root password
Even if you have a suggestion to fix one of the errors, please still comment
Also, if you need any more information please let me know
You're getting several error messages because you have several problems :)
Cannot connect: invalid settings
Some setting is incorrect, most likely something in your config.inc.php is misspelled or incorrectly copied and pasted. Specifically, if the line ['Servers'][$i]['(MySQL root password)'] = '';$cfg is actually how it appears in your configuration, that is clearly the problem as the line should actually be $cfg['Servers'][$i]['password'] = 'green'; except with you password instead of 'green'...except that only applies if your auth_type is 'config', otherwise the 'password' line isn't used at all (since you're prompted for the password at log in). I'm not sure what XAMPP does here for auth_type, but I don't think you should have had to edit the configuration file at all, since you used the XAMPP installer which should have configured everything.
The server requested authentication method unknown to the client [sha256_password]
This appears to be a bit of a version mismatch in your installed files. Access denied after setting user's password with SHA256 in phpMyAdmin goes in to more detail, but this most often occurs when you've got MySQL 8 and PHP older than 7.4. Normally, I'd suggest upgrading your PHP version — but you're using the packaged XAMPP, which certainly wouldn't ship with conflicting MySQL and PHP versions, so something is odd here. Please confirm for us your MySQL and PHP versions. You didn't happen to have an existing MySQL or PHP installation before you installed XAMPP, did you?
Connection for controluser as defined in your configuration failed
This is probably related to the MySQL 8/PHP 7.4 conflict. There is an administrative user (called the controluser) that phpMyAdmin can use to manage some extra features, ordinarily you wouldn't need it to access phpMyAdmin (only to access those additional features), but it seems XAMPP has configured this for you. Since the authentication fails, you get an additional message that the controluser was not able to connect.
You could bypass this by commenting out the configuration lines referencing controluser and controlpass, although again the XAMPP package should have this all configured so I don't recommend that at this point.
The other messages are basically echoes of the previous messages; you get an additional protocol notification because the controluser is trying the same sha256 connection type that the main user was, and then finally phpMyAdmin is telling you that MySQL rejected the connection.
If this is a fresh XAMPP install, I'd suggest reinstalling, because something got a bit confused. I'd also suggest making sure that you don't have any other conflicting software running — XAMPP is a package of all the included parts, so you don't want to install or run your own Apache or MySQL instance which would interfere with the packaged kit.
I'm trying to set up WAMPServer for the first time on my personal computer to do some WordPress work. When I try to log into phpadmin with the root login, I get an error screen. The Error reads as such:
SQL query: Edit
SET lc_messages = 'en_US';
MySQL said:
1193 - Unknown system variable 'lc_messages'
I've tried running PHP version 7.0.10 and 5.6.25 but the errors occurred on both.
I'm running MySQL version 5.7.14
I've tried looking at a StackOverflow forum with the same issue, linked here, but none of the suggested fixes worked for me there, since I'm running a pretty updated version of phpMyAdmin.
The correct name for that parameter is lc-messages note a hyphen and not an underscore.
Have you amended anything in the 'my.ini'?
RE: Your Comment
Then potentially you have another MySQL runing or maybe just a rouge my.ini file on your system.
Search for my.ini and if you find it anywhere other then inside the \wamp\ or \wamp64\ folders, remove or rename it. There should not be one outside the wamp folder structure.
Worked for me
On my system there was another SQL SERVER was running, that was the problem.
Simply go to WAMPMANAGER-> MySQL-> Use a port other than 3306
(In my case, Wamp Manager automatically selected port 3308)
click ok and restart the wamp server.
I have installed WAMP server for PHP. MySQL extensions are enabled. I have written echo "hi" and run it on WAMP , it did show me proper output as Hi. When I use following snippet:
mysql_connect("localhost","root","")
I get message as Internet explorer can not displays web page.User Id and password are correct.
Replacing localhost with 127.0.0.1:3306 does not resolve this issue.
From what you posted in comments, it looms like the MySQL module might not be activated in your php configuration (php.ini).
To check this, write a blank page and put 'phpinfo();' in there. Look for installed modules and check whether MySQL is in there.
If not, edit your configuration accordingly.
I'm venturing out of the world of .NET and into the world of open-source. However, I've hit a few roadblocks while trying to get my development environment set up. And I'm kind of stuck on the most recent one.
I have installed: Apache 2.2, php 5.3.2, and mySQL 5.1.48
everything is working pretty much; apache is serving up PHP pages, and I'm able to create databases and tables in mySQL, however, I can't seem to get php to communicate correctly with mySQL. My php.ini has these lines un-commented:
extension=php_mysql.dll
extension=php_mysqli.dll
However, I keep getting this error message:
Warning: mysqli_connect(): (HY000/2002): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\mysql_test.php on line 15
any help would be greatly appreciated.
(btw, the php code runs properly when I put it on my web host)
This is most likely a configuration problem with the MySql server. It sounds like it either isn't listening on the correct port or something else is going on with the connection. You have the extensions loaded correctly because PHP is able to find the mysql functions. I would make sure you don't have a firewall blocking any of the requisite ports (actually, just try turning off your firewall and see what happens...just don't forget to turn it back on ;-) ). Also make sure if you are following a tutorial you didn't deviate from the MySQL setup instructions at all. If those don't work, post an update and we can try again.
This looks like bug #45150 : MySQL functions cannot be used with 5.3.x on Vista when using "localhost" -- I've had this problem once, and it took me some time to figure out what was causing it...
If you are working with Windows Vista (and possibly seven ?), and trying to connect to MySQL using "localhost" as host, try to replace that by the corresponding IP address : "127.0.0.1"
Or try to edit the hosts file, and to un-comment the line that corresponds to localhost in IPv4 :
127.0.0.1 localhost
(Remove the # at the beginning of the line)
Or to comment the line that corresponds to localhost in IPv6 :
#::1 localhost
(Add a # at the beginning of the line)
And here's an interesting article about that : PHP 5.3 and MySQL connectivity problem
Use XAMPP - it'll remove any headaches like this for local development.
XAMPP is a very easy to install Apache Distribution for Linux, Solaris, Windows and Mac OS X. The package includes the Apache web server, MySQL, PHP, Perl, a FTP server and phpMyAdmin.
