It’s worth nothing, first of all, that I’ve got a fully-functional Apache2 server (on a Ubuntu 12.04 VPS) with multiple working virtual hosts (but this is my first attempt to deploy a Rails site). Additionally, the Rails site I’m trying to launch is fully functional on my local WEBRick server.

I’ve referenced various online instructions for making Apache, Ruby, Rails & Passenger play nice together, including:

To summarize, so far I’ve:

  1. Installed Ruby (ruby -v in site root returns 1.9.3), RVM, Ruby Gems, Rails (rails -v in app folder returns 3.2.8 and I can start a rails server in the app folder) & Passenger (including all dependencies)

  2. As instructed by passenger-install-apache2-module, I’ve added the following lines to the bottom of /etc/apache2/apache2.conf:

    LoadModule passenger_module /var/lib/gems/1.8/gems/passenger 3.0.17/ext/apache2/mod_passenger.so
PassengerRoot /var/lib/gems/1.8/gems/passenger-3.0.17
PassengerRuby /usr/bin/ruby1.8

  3. Created & enabled (it’s listed in /etc/apache2/sites-enabled/) a virtual host /etc/apache2/sites-available/foo.com that contains the following: 

    <VirtualHost *:80>
  ServerName foo.com
  DocumentRoot /home/user/public/foo.com/public
  <Directory /home/user/public/foo.com/public>
    AllowOverride all
    Options -MultiViews
  </Directory>
</VirtualHost>

  4. Uploaded my Rails app to /home/user/public/foo.com/

  5. Did a bundle install in /home/user/public/foo.com/

  6. On my local OSX machine, I’ve add xxx.xxx.xxx.xxx foo.com [the VPS IP] to /etc/hosts.

  7. Restarted Apache

But when I navigate to foo.com in the browser, I simply see a listing of /home/user/public/foo.com/public. Also, there are no recent entries in the Apache error.log. However, whenever I restart Apache I get: 

 * Restarting web server apache2
[Fri Oct 26 00:04:12 2012] [warn] module passenger_module is already loaded, skipping
 ... waiting [Fri Oct 26 00:04:13 2012] [warn] module passenger_module is already loaded, skipping
   ...done.

I’m hoping I’ve overlooked something really stupid. Any help figure out what that is would be much, much appreciated. Thanks!

    If you’re working with apache2.2, you should not include the following in apache2.conf

    LoadModule passenger_module /var/lib/gems/1.8/gems/passenger 3.0.17/ext/apache2/mod_passenger.so
PassengerRoot /var/lib/gems/1.8/gems/passenger-3.0.17
PassengerRuby /usr/bin/ruby1.8

    Instead you should create 2 files on /etc/apache2/mods-available:

    passenger.load with:

    LoadModule passenger_module /var/lib/gems/1.8/gems/passenger3.0.17/ext/apache2/mod_passenger.so

    passenger.conf with:

    PassengerRoot /var/lib/gems/1.8/gems/passenger-3.0.17
PassengerRuby /usr/bin/ruby1.8

    Finally you just run:

    a2enmod passenger

    And it’s done. By the way, when you make it work you might consider using a more recent version of ruby (1.9.3… or so). The best way to do that is using RVM.
