For some reason my MySQL can't connect any more. I'm running three WordPress sites and I need to save the tables. That's what I really really really really care about.

Here is the problem:

root@dev:/var/log/mysql# mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

The same error is displayed when logging in with phpMyAdmin..

All of the websites display this error:

Error establishing a database connection

Have you tried restarting MySQL? You might have just run out of sockets because of a DDOS attack. – Paul Tomblin Aug 31 '12 at 23:34

mysql server is down... database files should not be deleted, if they are deleted or corrupted check binlogs, you can recover db from binlogs if enabled – Hawili Aug 31 '12 at 23:34
Shut down your web server, and try restarting MySQL server. Probably everything is fine. If not, aren't you glad you take daily backups? – Paul Tomblin Aug 31 '12 at 23:35

mysql is not running - why don't you try starting it

And of course none of this should be a real issue because you have regular backups right?

What if he isn't an admin? – njk Aug 31 '12 at 23:36
I think the answer to that is obvious – Adrian Cornish Aug 31 '12 at 23:37
linode's business grants ssh access to customers. If the original questioner isn't an admin, he surely has a colleague who is. – Ollie Jones Aug 31 '12 at 23:39
