Phusion Passenger is an Apache module, which makes deploying Ruby and Ruby on Rails applications on Apache a breeze. It follows the usual Ruby on Rails conventions, such as “Don’t-Repeat-Yourself” and ease of setup, while at the same time providing enough flexibility.

Phusion Passenger is a commercial supported open source product that enables people to deploy their Ruby on Rails applications in an upload-and-go manner, which is very reminiscent of the PHP way of deploying. Also, you can always get community support on Discussion board.
