h1. Moving to Rails 3

h2. Test environment

We have a Redmine 2.2 pristine branch (redmine-2.2) and an integration branch (redmine-2.2-integration) in which to fix errors arising from merging our own changes back in to Redmine 2.2.

For Rails 2, we have been using Ruby Enterprise Edition v1.8.7 with Phusion Passenger v3.0.1.

For Rails 3 we want to use a more mainstream Ruby v1.9.3, with Phusion Passenger v3.0.18.

Ubuntu 10.04 LTS only has Ruby 1.9.1, so we use the Brightbox packages.

<pre>

 $ sudo apt-add-repository ppa:brightbox/ruby-ng

 $ sudo apt-get update

 $ sudo apt-get install ruby1.9.3

 $ sudo gem1.9.3 install rails

 $ sudo gem1.9.3 install passenger

 $ sudo apt-get install libcurl4-openssl-dev

 $ sudo passenger-install-apache2-module 

</pre>

The Passenger installer prints out:

<pre>

Please edit your Apache configuration file, and add these lines:

   LoadModule passenger_module /var/lib/gems/1.9.1/gems/passenger-3.0.18/ext/apache2/mod_passenger.so

   PassengerRoot /var/lib/gems/1.9.1/gems/passenger-3.0.18

   PassengerRuby /usr/bin/ruby1.9.1

</pre>

(Note that the Brightbox PPA "Ruby 1.9.1" is in fact 1.9.3, unlike the Ubuntu repo package which is 1.9.1 -- confusing)
