Installing Phusion Passenger on Ubuntu 10.04 LTS

Before installing Phusion Passenger you will need a working installation of Rails:

apt-get install ruby rubygems # distro packages rubygems 1.3.7
gem install rubygems-update
PATH=$PATH:/var/lib/gems/1.8/bin
update_rubygems
gem install rails -v=2.3.4 # or whatever

The Phusion installation script builds an Apache loadable module by linking various libraries. Make sure these libraries are installed before running the script.

apt-get install build-essential ruby1.8-dev libopenssl-ruby
apt-get install apache2 apache2-prefork-dev libapr1-dev libaprutil1-dev
apt-get install libcurl4-openssl-dev

gem install passenger
passenger-install-apache2-module # compilation dependencies satisfied above

The Passenger installation script displays a message to add some lines to your Apache configuration script. One way to do this with Apache2 on Ubuntu is:

cat > /etc/apache2/mods-available/passenger.load <
   LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.15/ext/apache2/mod_passenger.so
   PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.15
   PassengerRuby /usr/bin/ruby1.8
EOF
a2enmod passenger
/etc/init.d/apache2 restart
