MySQL Error

[DazzyB]

I'm having issues with MySQL... I have installed Ubuntu Dapper LAMP Server and after installation MySQL works, then I setup my Hosts file and networking etc... and after I restart I get this:

root@mail:~# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
root@mail:~#
I have re-installed 3 times already, and been up and down google and I have yet to find an answer, can anyone help?

[falko]

What's the output of netstat -tap and ps aux | grep mysql?
What's in /etc/mysql/my.cnf?

netstat -tap:

Looks ok. Can you connect using
mysql -u root -p?

[DazzyB]

Well it askes for a password, but the mysql client is trying to connect via /tmp/mysql.sock

and the sock file is in /var/run/mysqld/mysql.sock

so I set that in webmin, and it works... in webmin that is, but thats all I need, its also fine on port 3306, so alls good.

root@carterweb:~# mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
