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.

• What directory structure do I need?
• What do I have to put in the vhost conf file?
• I understand I need a rackup file. What goes in it and why?

Answer 1

Basic directory structure:

app |-- config.ru         # <- rackup file |-- hello-app.rb      # <- your application |-- public/           # <- static public files (passenger needs this) `-- tmp/                   `-- restart.txt   # <- touch this file to restart app 

Virtual host file:

<VirtualHost *:80>   ServerName    app.example.com   DocumentRoot  /path/to/app/public   <Directory    /path/to/app/public>     Order       allow,deny     Allow       from all   </Directory> </VirtualHost> 

config.ru

# encoding: UTF-8 require './hello-app' run Sinatra::Application 

hello-app.rb (sample application):

#!/usr/bin/env ruby # encoding: UTF-8 require 'rubygems' # for ruby 1.8 require 'sinatra'  get '/hi' do   "Hello World!" end 

restart.txt is empty.
