Ruby on rails is a open-source framework very powerful and useful to optimse the development and productivity

Mod_passenger is use to run rails application via APACHE.

Requirement :

Before the install the installation of Ryby on rails with mod_passenger you need to install some packges.

If you want to use SVN with ruby for capistrano for example, you have to install subversion

yum install subversion

If your application need to access to a mysql server, you have to install the lib to enable the mysql ruby dependency.

yum install mysql-devel

For the installation of passenger, you need to install the compilation tools like GCC and the devel code for http and apr-util

yum install gcc gcc-c++ libstdc++ httpd-devel apr-util-devel

Installation of Ruby

On redhat or centos you have the base for the installation of ruby but the version of ruby is limit to 1.8.5 for the moment.

yum install ruby ruby-devel ruby-libs ruby-irb ruby-rdoc subversion-ruby

Installation of GEMS

Download GEMS

I recommend to use the archive version instead of the rpm. You can found some rpm for rubygems and dependencies but if you use it you have to follow it.

wget http://rubyforge.org/frs/download.php/60719/rubygems-1.3.5.zip

ls -al
unzip rubygems-1.3.5.zip
cd rubygems-1.3.5
ls -al
ruby setup.rb
gem update
gem
gem help command
gem update --system
cd ..
rm -Rf rubygems-1.3.5

Installation of dependencies

• Base dependencies
  

The installation of rails could take a long time and a lot of ressources

gem install rails --include-dependencies --no-rdoc --no-ri
gem install capistrano --include-dependencies --no-rdoc --no-ri
gem install mongrel --include-dependencies --no-rdoc --no-ri

• Mysql dependency

For mysql, if you have the RUBY version > at 1.8.6, you can install this dependence by gems like that :

gem install mysql -- --with-mysql-config=/usr/bin/mysql_config

If you have ruby version >1.8.6 use this way to install mysql dependency

rpm -i ftp://mirror.switch.ch/pool/1/mirror/epel/5/x86_64/ruby-mysql-2.7.3-1.el5.x86_64.rpm

Installation of passenger

For the installation of passenger, you can use the GEM install, but if you want to use a RPM Package use this SRPMS

gem install passenger

Installation of mod_passenger

passenger-install-apache2-module
Welcome to the Phusion Passenger Apache 2 module installer, v2.2.5.

This installer will guide you through the entire installation process. It
shouldn't take more than 3 minutes in total.

Here's what you can expect from the installation process:

1. The Apache 2 module will be installed for you.
2. You'll learn how to configure Apache.
3. You'll learn how to deploy a Ruby on Rails application.

Don't worry if anything goes wrong. This installer will advise you on how to
solve any problems.

Press Enter to continue, or Ctrl-C to abort.

Now you have to press 1 to install and compile the mod_passenger

--------------------------------------------
The Apache 2 module was successfully installed.

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

LoadModule passenger_module /usr/lib64/ruby/gems/1.8/gems/passenger-2.2.5/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib64/ruby/gems/1.8/gems/passenger-2.2.5
PassengerRuby /usr/bin/ruby

After you restart Apache, you are ready to deploy any number of Ruby on Rails
applications on Apache, without any further Ruby on Rails-specific
configuration!

Press ENTER to continue.

--------------------------------------------
Deploying a Ruby on Rails application: an example

Suppose you have a Ruby on Rails application in /somewhere. Add a virtual host
to your Apache configuration file, and set its DocumentRoot to
/somewhere/public, like this:

<VirtualHost *:80>
ServerName www.yourhost.com
DocumentRoot /somewhere/public # <-- be sure to point to 'public'!
</VirtualHost>

And that's it! You may also want to check the Users Guide for security and
optimization tips and other useful information:

/usr/lib64/ruby/gems/1.8/gems/passenger-2.2.5/doc/Users guide Apache.html
