This is my guide on how to change the port your server runs on.....
First find your mysql configuration file
open it up
then you should see the 3306 ports one is at the top and one is near the middle
just change it to 4337(thats is a port I found efficent)
after that open up all your configuration files and everything that says 3306 change to 4337
