Ruby on Rails Software Collections

The following collections are available for Ruby on Rails, rebuilt from RHSCL:

• ruby193, with Ruby on Rails 3.2 and Ruby 1.9.3
• ror40, with Ruby on Rails 4.0 and Ruby 2.0
• rh-ror41, with Ruby on Rails 4.1 and Ruby 2.2

The following RoR collections are developed in the SCLo:

• sclo-ror42, with Ruby on Rails 4.2 and Ruby 2.2

1. Using with Passenger

The main Ruby collections are integrated with the rh-passenger40 and httpd24 collections, which makes it easy to run Ruby on Rails applications under a full SCL stack.

First install the Passenger module, which will also install httpd24, and the appropriate Passenger/Ruby combination for the collection in use:

yum install rh-passenger40-mod_passenger rh-passenger40-ruby22

Use the VirtualHost example from /opt/rh/httpd24/root/etc/httpd/conf.d/passenger.conf to configure the site in /opt/rh/httpd24/root/etc/httpd/conf.d/, e.g.

<VirtualHost *:80>
   ServerName example.com
   PassengerRuby /opt/rh/rh-passenger40/root/usr/libexec/passenger-ruby22
   DocumentRoot /var/www/public
   <Directory /var/www/public>
      AllowOverride all
      Require all granted
      Options -MultiViews
   </Directory>
</VirtualHost>

Change the passenger-ruby* binary referred to in the PassengerRuby setting as appropriate. The app root is expected to be /var/www in the example here.

Start the web server using service httpd24-httpd start.

If using sclo-ror42 (or another non-rh* collection), the collections that get activated may need to be changed in /opt/rh/rh-passenger40/service-environment. For example, using sclo-ror42, edit RH_PASSENGER40_RUBY22_SCLS_ENABLED and change rh-ror41 to sclo-ror42. If asset precompilation isn't used or runtime compilation is desired, add v8314 too.
