After upgrading to OS X 10.8, some of you might have noticed that the “Web Sharing” option is no longer available from the Sharing Panel of Systems Preferences.

Fear not!

While Apple has removed the user-interface (a mere checkbox) for Apache (the Web/HTTP service), it is still available and installed in Mountain Lion, fully functional.

To turn it on:

$ sudo apachectl start

To turn it off:

$ sudo apachectl stop

Apache configuration files are available in /etc/apache2/.

You might want to use it with Pow if you do Ruby development.
