XAMPP apache服务无法启动

Hello if you are using Skype then from Skype Tools->options->Advanced->Connection in this check Use-port there one text box may be there default port using 80 so make that box empty. and save logout from Skype and login again now your skype use port other than 80 so now your Apache is working fine.

And there is other solution is also you can also change your default port for Apache 80 to other from Apache httpd.conf ServerName localhost:80 to any other free port like ServerName localhost:81 may helps you.

Here's how I figured it out:

1. In Control Panel, click on Apache ---- Config button and open the file in the first line (httpd.conf), here

2. Search for these lines
   #Listen 12.34.56.78:80

   Listen 80

   ServerName localhost:80

And replace 80 in these lines by another number x, probably a unique one to avoid duplicate. Eg, 2017.

3. In Control Panel, click on Config button in upper right corner, here.

   Service and Port Settings > Main Port: replace the old one with x

That's how mine works. Hope it helps you.
