[CentOS] Centos 6.6 Can't connect to local MySQL server through socket /var/lib/MySQL/MySQL.sock (error 2002)‏

 Hi 
 
Total newby to centos I am currently assisting a community radio station set up in the Uk we are using a server based system for our playout software, unfortunately at the moment one of our client servers is experience the above error I came across the error on our main server a few weeks ago and found the solution just by reinstalling the MySQL db but I have tried to deploy the same fix on our client server otherwise known as studio-b client but unfortunately this has not solved the problem any assistance with this would be very much appreciated.
 
All the best
