Setting up Ubuntu for Rails App via Passenger

These instructions apply to Ubuntu 11.04 (natty).

Run the following to install Ruby, the Apache2 web server, Curl Development Headers with SSL Support.

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install ruby ruby1.8-dev
sudo apt-get install apache2 apache2-mpm-prefork apache2-prefork-dev libcurl4-openssl-dev

Next download Ruby Gems, extract the package, install Ruby Gems, and then create a symbolic link from /usr/bin/gem1.8 to /usr/bin/gem

cd ~
tar -zxvf rubygems-1.8.10.tgz
cd rubygems-1.8.10
sudo ruby setup.rb
ln -s /usr/bin/gem1.8 /usr/bin/gem

With Ruby Gems installed we can install the Passenger gem.

sudo gem install passenger

Now we can run the installation of Passenger for Apache2.


At the end of the build the installation instructions tell you to add something like the following to your Apache configuration file.

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.9/ext/apache2/
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.9
PassengerRuby /usr/bin/ruby1.8

Do this by copying the commands, then pasting them into /etc/apache2/mods-available/passenger.load

sudo nano /etc/apache2/mods-available/passenger.load

After saving the file, run the following commands to load the module and restart the Apache web server.

a2enmod passenger
/etc/init.d/apache2 restart

Now you can create a virtual host file for your site under /etc/apache2/sites-available

sudo nano /etc/apache2/sites-available/

Then setup this virtualhost file to load and tell Apache to reload the configuration

/etc/init.d/apache2 reload

For your application to run you’ll need to install the Rails gem of course.

sudo gem install rails
