Need Help Increasing MYSQL Connections!

I have a small VPS and up to now I've never had to increase the max MYSQL connections. I'd love some help in this depertment:

Step By Step, exactly what I need to type in SSH to get this to work right.

 

If it doesn't exist, create the file /etc/my.cnf and add the following lines:

[mysqld]
max_connections=300

You can change 300 for whatever you wish.

 

Thanks. It was set to 100 and with 50 sites all running heavy, the server was spitting out errors like no tomorrow.

 

You're welcome
