I've installed mysql and when I try to use it, it says that 'Can't connect to local MySQL server through socket /var/lib/mysql/mysql.sock
I've checked and the file doesn't exist. How do I create it? Or do I have to create it manually. If yes then what do I write in it?

Ok I looked after it I start it with 'mysqld_safe &' and it gives me the following message:

[1] 20497

You must make sure that mysqld is running.

This is pretty common, where you expect to see the socket, just create a link to the real one, which can be found with a locate. You will need something like ln -s /the/real/socket mysql.sock

I agree with Spirit_Receiver. If the mysqld server isn't running, how can you expect the client to connect to it?

To fix all the "No such file or directory" errors, make sure that the directory
/usr/local/var exists and is writable to the user that MySql runs under.

Hey, you're cheating. You changed your first post considerably.

Now that I know you're using SUSE, I can make the following suggestion: If you want to start the server manually, su to root and use the command "rcmysql start". Then you should be fine.
Alternatively, you can also use YaST to specify the runlevels in which mysqld should always be started automatically. See YaST->System->Runlevel-Editor.

Thnx I fixed it from YAST.
