Error Can\'t connect to local MySQL server through socket Why How Fix Solve

the other day i was getting this error message and i wondered why do I get a MySQL "Can't connect to local MySQL server through socket" error?

Answer: This indicates that PHP cannot communicate with your MySQL server. Check to make sure that MySQL is running, and verify that it's actually on the server where you think it is. If MySQL is running on your local system try using the IP address for your host (which should be 127.0.0.1) instead of "localhost" for your database and see if that fixes the problem. For other diagnostics you can try, take a look at http://dev.mysql.com/doc/refman/5.0/en/can-not-connect-to-server.html

Another problem you might have is that you may have your credentials incorrect. check to make sure you have the username, password, database correct. A customer of mine, changed his password and forgot to change in his configuration file and that's whay he was getting this error.
