Setting Up Ruby on Rails

RoR (Ruby on Rails) is an open-source software designed to build various web applications. Ruby on Rails is divided into two parts: Ruby, which is a versatile general-purpose programming language, and Rails, which is a framework for building websites, apps, and systems. Rails is similar to a default user-friendly structure, making it easy to create anything.

Ruby on Rails Installation

You can install the latest version of Ruby on Rails or whatever version you want (provided it's compatible with Ruby 1.9.3) as a local user: gem install rails --no-rdoc --no-ri. Create a new Rails application.

Rails 3.x

rails new ~/APPNAME -d mysql

You can specify the version using "-v" (for example, gem install rails -v 3.0.11 --no-rdoc --no-ri).

RoR Access

If you are using a subdomain, follow the How To Create A Subdomain steps. Make sure the Document Root box points to the folder you want the subdomain to be tied to (for example, if the name of your subdomain is 'APPNAME', point it to the public_html/APPNAME folder).

You will then need to create a Symlink to the public folder of your application. Enter the following command:

ln -s ~/APPNAME/public ~/public_html/APPNAME

.htaccess File Setup

You'll need this in the public folder for the app, which sets everything up, including where to look for user-installed gems. To add this, simply run the following commands:

1. rm ~/APPNAME/public/.htaccess
2. vim ~/APPNAME/public/.htaccess
3. Press i to edit the file.
4. Paste in the code from below.
5. Enter :wq
6. Press Enter to save the changes.

<IfModule mod_passenger.c>
Options -MultiViews
PassengerResolveSymlinksInDocumentRoot on
#Set this to whatever environment you'll be running in
RailsEnv production
RackBaseURI /
SetEnv GEM_HOME /home1/examplec/ruby/gems
</IfModule>

.bashrc Configuration

You will need to add the following to your ~/.bashrc file.

~/.bashrc file

export HPATH=$HOME
export GEM_HOME=$HPATH/ruby/gems
export GEM_PATH=$GEM_HOME:/lib64/ruby/gems/1.9.3
export GEM_CACHE=$GEM_HOME/cache
export PATH=$PATH:$HPATH/ruby/gems/bin
export PATH=$PATH:$HPATH/ruby/gems
