Phusion Passenger on Ubuntu 9.10

At first I was thrown by the Phusion Passenger installation instructions when it talked about enabling the Passenger module in apache .conf file. In Ubuntu the enabling/disabling of modules does not sit in a .conf file but, in fact, split into individual .load/.conf files in the /etc/apache2/mods-available folder.

This means when you enable a module with a2enmod in Ubuntu it simply makes a symlink from mods-enabled -> mods-available and disabling a module (with a2dismod is just as easy. No more hunting in those .conf files.

So I wanted to keep things using the same idea of using the mods-enabled directory as opposed to using one large apache2.conf file.

Phusion Passenger Installation

Passenger is drop dead simple to install, here’s the steps.

Update the system

?View Code BASH
sudo apt-get update
sudo apt-get install apache2-prefork-dev

Now Install Phusion Passenger

?View Code BASH
sudo gem install passenger
sudo passenger-install-apache2-module

Passenger is now installed; let’s get it enabled.

Create the .load/.conf in mod-available

Create the .load file with sudo nano /etc/apache2/mods-available/passenger.load and paste in the following:

?View Code TEXT
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.9/ext/apache2/mod_passenger.so

Note: The version numbers I’ve used might not be what you have installed; Passenger will give you the correct version numbers on screen once installation is complete.

Create the .conf file with sudo nano /etc/apache2/mods-available/passenger.conf and paste in the following:

?View Code TEXT
<IfModule passenger_module>
   PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.9
   PassengerRuby /usr/bin/ruby1.8
</IfModule>

Enable Passenger

Enabling Passenger is as simple as:

?View Code BASH
sudo a2enmod passenger
sudo /etc/init.d/apache2 restart

And you will need to change your /etc/apache2/sites-available/default to read:

?View Code TEXT
<VirtualHost *:80>
    ServerName www.rackapp.com
    DocumentRoot /webapps/rackapp/public
</VirtualHost>

And you’re done. You’re up and running with Phusion Passenger.
