Can't connect to MySQL with PHP

[admin]

I have run out of ideas and need some help. I've tried implementing all the solutions outlined throughout this site and nothing works yet.I'm running RedHat 7.1. I installed the latest release of MySQL and run every test in the books. Everything works perfectly.When I try to connect with either MySQLGUI or PHP I get the error:Can't connect to local MySQL server though socket " (111)I've ensured that the mysql.sock exists in var/lib/mysql.I've created the link in the /tmp/ folder.I've updated the my.cnf fileI've rest all permissions on those files to chmod 777etc. etc. etc...As I stated, the MySQL is running and everything tests fine.Any help would definately be appreciated. I've spent two days on this so far and read every thread, readme file, and help file I can find.
