Solved: Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’

June 28, 2015   /   by Marco  / Categories :  Technology

My VPS server experienced an issue with mySQL server and thought I’d better document how to resolve it in case it happens again.

The symptoms

  • An Error message saying unable to connect to the database comes up when trying to access websites using WordPress
  • Manually starting the mysqld came back with “Failed”- using the command
service mysqld restart
  • Rebooting didn’t fix the problem
  • When trying to run “mysql” an error message came back with
    Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'

The solution

For some reason this worked for me – it may not work for you.  All you have to do is run the database in recovery mode so follow these instructions:

SSH into your VPS server

Edit the my.cnf file in the folder /etc and add the following line:

innodb_force_recovery = 1

Then save the file

Restart mysqld by using the following command:

service mysqld restart

It should now work. If the server started with OK then it worked.

Go back and disable the innodb recovery by either removing the line or just adding a # at the front.

Hopefully this has fixed your issue.
