ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")

Error:

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2 “No such file or directory”)

After following all the steps of a tutorial to make a cluster with galley and mariadb. Everything worked fine until I made a copy and then create a new drop.

No matter what I do I always encounter this error when restarting mysql.

If I never turn off the drop or never recover with a previous image does not give the bug.

But I turn off the drop to make it bigger. Or I just turn it off and on.

It gives me this error and I did not step from this step.

Did anyone else tube this error?

While this is an old question I though it might be good to answer for someone else who is having the same issue. For me it was a matter of /var/lib/mysql/tc.log growing rapidly in size. After removing the tc.log mariadb started working again.

I had the same problem. I just need to run sudo service mysql start it happen to me and worked on it for 15 mins and then I wanted to kick myself in the butt once I figure I need to start mysql. Sometimes it doesn’t always start. :)

One of the most common issues I’ve ran in to is the systemd or init script is passing a different path than is defined in your my.cnf file for the socket, thus when you attempt to start or restart MySQL, it fails.

So the best thing to do would be to check my.cnf and the associated configuration files to see what is being defined for the socket. If your MySQL configuration is defining something other than what the startup script is asking for, change socket= to /var/run/mysqld/mysqld.sock, save + exit, and then try to restart MySQL/MariaDB again.

Otherwise, you could do the reverse. Check the startup script and change the path of the socket to match that of what’s defined in your MySQL configuration.
