Https:could not reliably determine the server ' s fully qualified domain name, using Localhost.localdomain.

1.

Open with Notepad

Remove the #ServerName localhost:80 comments from the inside.

Re-execute

HTTP://LOCALHOST:80 can then be accessed through a browser if the page displays "It works! ", which means that Apache has been installed and started successfully.

or use Curl http://localhost:80
