After reinstalling wampserver and copying database folders from \wamp\bin\mysql\mysqlx.y.z\ to new \wamp\bin\mysql\mysqlx.y.z\data, i get this error:
Error establishing a database connection
please kindly help out.!
First Just check mysql server is running.Can you log in to MySQL with the mysql command line ? Let's start there to see if the MySQL service is running.
Sometimes it maybe a conflict with skype.If that so,first logout from the skype & the shutdown that process and after that click and restart the wamp server.

Got a new laptop [Windows 11] and for the first time I am facing issues with MySQL server. It installs alright but fails at the step "Starting server".
When I check the logs on the next tab I get the error message:
Attempting to connect to Mysql#localhost:3306 with user root with no password... MySQL error 1042: Unable to connect to any of the specified MySQL hosts.
I have tried other versions, tried to start server from services, changed to Local System Account under service properties, but still the server just wont start.
Every time I reboot my computer and try to access my mysql database it produces the following error:
ERROR 2002 (HY000):
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
any ideas on how to resolve this?
It might be that your MySQL is not started automatically on system start-up. Kindly execute mysqld to start the MySQL.
Or please refer https://askubuntu.com/questions/416309/start-mysql-on-startup, to start MySQL on system start-up, assuming that you are on Linux OS.
I've run into a problem here, and I'm not sure what to do. I migrated a Yosemite Mac to a new Mac Pro. Apache turns on, but MySql does not with this error: The operation couldn’t be completed. (XAMPPErrorDomain error 1.)
I didn't know if I need to reinstall MySql or upgrade it, or what this error means. I created the plist file as in the example and ran permissions, but that did not change the outcome. Going to websites in localhost, WordPress shows an error establishing db connection.
I went to Github to install MySql and it went fine, but it does not work with Xampp and Desktop Server. I chose to NOT start MySql when I rebooted, but apparently the Github version started anyway (and I cannot find a way to turn it off!) Now when I try to start MySql from Xampp, it says another version is already running.
Any help appreciated.
When I ask for version number in terminal I get this response:
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
HOWEVER, when I went to /var/ and temp I found an alias for mysql.sock, BUT it was not connected to an original file... Now that file does not exist anywhere on my computer.
Open /Applications/XAMPP/xamppfiles/xampp and add this line somewhere at the top:
unset DYLD_LIBRARY_PATH
I found that what was required was a complete uninstall of MySql following this procedure: http://bytearrays.com/completely-uninstall-mysql-mac-osx/
And then a reinstall. ServerPress.com was very helpful in diagnosing the problems.

There is an issues with you my.cnf file. I will suggest you please check your MySQL error logs file, With that logs you can find out the root cause of your issues
I have my websites on a VPS - CentOS. Suddenly all of them stopped working and are showing database connection error.
I have tried restarting mysql with the following command in SSH /etc/rc.d/init.d/mysqld restart but when it tries to stop it it says "Failed".
Any idea on what could I do?
Please check you mysql log file (/var/log/mysqld.log).
