[ubuntu] MySQL wont start after IP change

view story

http://ubuntuforums.org – Does anyone know how to change the LAN IP of your server and maintain connection to MySQL server. I have phpmyadmin installed and when I changed the LAN IP I lost the ability to log in. I recieved and error with: SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) I have a MySQL based website that also became unavailable when I try to access it.
