'''Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’'''

This error can be quite a pain when setting up a new server.  It normally is not hard to fix so here are the ways we have used the most:

* Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’

 Your mysql.sock might be located elsewhere use ‘find / -name mysql.sock’
 If it is located else where then ln -s [target] [nameoflink] this will link the file and allow it to start.

* Permissions

 If you didnt find mysql.sock on your system then do ‘cd /’
 Then ‘chmod 777 tmp’

Those should fix the issue
