1) nano /etc/mysql/my.cnf
2) find
[mysqld] user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp language = /usr/share/mysql/English bind-address = 65.55.55.2

Just a few minutes ago, i encounted a fairly common problem that would be hard to figure out without someone telling you how to do it. A server with mysql server quit working and we were getting die errors every time we tried to connect to the database. Wanna know how i fixed it?? well here you go...

1) log on to the linux console

2) restart the mysql server
/etc/init.d/mysqld restart
(this works on debian)

3) connect to the sql server
mysql -u=root -p
(note root is the root user for mysql)

4)
mysql> show databases;
