I have been trying to learn php and MySQL stuff for hosting my own website. I will write a separate post on how to configure and initial settings.

But main problem all will encounter will be the port 80 already running.

If any other service runs in port 80, then the apache server service wont start. It will keep begging you to clean port or change port.

The one simple solution is to change the listen port in the httpd.conf
Change Listen 80 to Listen 90. Here the port 90 can be anyother free port.

If not and you desperately wanted to change the port, then you need to scan all your ports. Check which process is using port 80 and kill it.

The one of the best freeware command prompt port scanner i use is fport.

Use it to find the port, and stop the process. Continue with your port 80. :)
