I've a Red Hat dedicated server with Plesk installed. Saturday I got this error on all my PHP pages: MySQL Connection Failed Can't connect to local MySQL server through socket '/tmp/mysql.sock'

I looked at all the doc and it really seems that this mysql.sock file has dissappeared from my server, probably because of some maintenance that deleted all files on my tmp dir. I now protected this /tmp/ directory but I still don't have this necessary mysql.sock file

Anyone knows if I have to re-install completely MySQL to get this file back? Or is there a command that would create it again automatically? I tried to restart MySQL but it doesn't solve the problem I need to have my server working for thursday!

Thanks A LOT in advance

That happened to me except for the file lived somewhere else. do a locate mysql.sock and then create a symbolic link from /tmp/mysql.sock to its real location.

i tried locating the mysql.sock file but it's gone!

how can i create this file again?

You need to restart MySQL in order to get it back, first you need to do killall mysqld, killall safemyslqd, then you need to start mysql with which ever daemon you use.

ah thanks! you saved my life!!! it's strange because i was doing a 'ps' command and it was telling me mysql deamon was not running. still the killall worked and i was able to restart mysql... thanks!

Yeah, that was exactly the problem I got at tera-byte (shared server!), but I didn't have to fix it, just a message to support (though it took 4hrs!)

It took me a few hours to work it out, on our old server we had a spate of it happening. MySQL partly crashes and you need to killall before you can restart it, we solved it before our provider did (Alabanza). But like I say it had me for about 4 hours while I searched through manuals and what not.
