Apache Webserver – A quick tutorial for new Admins
Apache is one of the most commonly used web servers out there. If you are running your own cPanel server your websites will actually run on Apache. If you’re new to administering a web server or just want to learn to keep your managed server under control without yelling for support each and every time it is useful to know some basic Linux commands for Apache. Unless specified otherwise – all commands listed need to be executed from the command line on your server.
