I Would Like To Host an HTML Website Without Using Server.app I am somewhat a novice when it comes to the Apache web server. I currently host Ruby on Rails applications on my Mac Mini Server (Mavericks) using Phusion Passenger.  I know that some of the config files are in different libraries than the standard Apache implementation.  I'm currently using Server.app to host one HTML website.  I would like to stop using Server.app to host it but I do not know how to set this up in Apache on an Apple machine.  The solutions I have found are not specific to the Apple setup for Apache.

I would appreciate help on how to do this from anyone who has done this.
Apache is there by default, you just need to turn it on:

sudo apachectl start

To tweak it to do what you want you may need to adjust the .conf files located at /etc/apache2/ These behave like any other apache configuration (though there are a few OS X specific modules installed).
