How do I set up a Sinatra app under Apache with Passenger?

Question

Let\'s say I have the simplest single-file Sinatra app. The hello world on their homepage will do. I want to run it under Apache with Phusion Passenger, AKA mod_rails.

Answer 1

Example vhost file for rack app with passenger:

 ServerName   server.local
 ServerAlias  *.server.local
 DocumentRoot /dir/public
 RackEnv      development
 
 Order allow,deny
  Allow from all
 

Example Config.ru:

require File.expand_path('../boot.rb', __FILE__)
use Rack::Middleware
run Rack::Cascade.new([array])
