MySQL connection not working: 2002 No such file or directory
Solution 1:
I had a similar problem and was able to solve it by addressing my mysql with 127.0.0.1 instead of localhost.
This probably means I've got something wrong in my hosts setup, but this quick fix get's me going for right now.
Solution 2:
If you use Linux: the path to the mysql.sock file is wrong. This is usually because you are using (LAMPP) XAMPP and it isn't in /tmp/mysql.sock
Open the php.ini file and find this line:
mysql.default_socket
And make it
mysql.default_socket = /path/to/mysql.sock
