Installing Ruby On Rails in Fedora

After noticing the struggle to install Ruby on Rail in Fedora by some of my dear fellows near me and having a lot of push talk by our branch manager I am going to post the way that I used to install Ruby on Rails in Fedora. Of course you can find help online, but none of them are straight forward and many time you can fall in a situation like “now what to do” if you are a novice in ROR like me. (Actually I know the installation only. hehe…). Hope you find it useful.

Install       8 Package(s)

# yum install rubygem-git

(the following will not be needed if first command dont install these)
# yum install rubygem-actionmailer rubygem-activerecord rubygem-activesupport 

APACHE CONFIGURATION:
---------------------------
# yum install ruby-devel
# gem install passenger
# passenger-install-apache2-module

This will create an .so file in: /usr/lib/ruby/gems/1.8/gems/passenger-X.X.X/ext/apache2/mod_passenger.so and the shell will tell you to add some code in httpd.conf and create virtual host.
e.g.
Edit the httpd.conf and at the eld of LoadModules section add the lines:

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.5/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.5
PassengerRuby /usr/bin/ruby

VHOST:

   ServerName relvurvey.jlk
   DocumentRoot /opt/www/relativesolutions-survey/public
   RailsEnv production

## Don't forget to edit the /etc/hosts file to reflect your newly created domain in conf

1) Application error....
The best way to locake the problem is to run the dispach.cgi. This will detect the problems that is causing problem running the application.
# cd to/public
# ./dispach.cgi
	Error A)
		/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- pdfkit (LoadError)
		from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
		from ./../config/environment.rb:12
		from ./dispatch.cgi:3:in `require'
		from ./dispatch.cgi:3
	Sol: gem install pdfkit

2) Internal Server Eroor...:
   >> Your log file may not be writable by the web server. (log/*)
   >> Your database configuration may not be correct. (config/database.yml)
   >> May be you need to restart the apache server if you are in middle of any erver configuration. But have a try with it anyway.
