How to change WAMP server port

TO CHANGE THE WAMP SERVER PORT NUMBER:

1. Stop the WAMP server, if it is running already.
2. Open the file [WAMPP Installation Folder]/apache/conf/httpd.conf.
3. Now search for the string Port 80 (I’m assuming that your WAMP was using the port 80. Otherwise, just search for the string “Listen”). This is the port number which WAMP uses. Change this 80 to any other number which you prefer.
4. Then search for the string “ServerName” and update the port number there also.
5. Now save and re-start WAMP server and you are done.
