Install Ruby on Rails on Ubuntu Linux

Installing Ruby on Rails on Ubuntu Linux isn't quite as easy as installing it on other operating systems. Here's a recipe that'll get you up and running in no time.

The most important step in this process is to edit the repository sources file and make sure that you have all the repositories that you need.

First, open the /etc/apt/sources.list file, find these lines and remove the # symbol from before them.

Code:

deb http://us.archive.ubuntu.com/ubuntu dapper universe main restricted universe 
deb http://security.ubuntu.com/ubuntu dapper-security universe

Next, run these commands from a Terminal window:

Code:

sudo apt-get update 
sudo apt-get install ruby ri rdoc 
sudo wget http://rubyforge.org/frs/download.php/11289/rubygems-0.9.0.tgz 
tar -xvzf rubygems-0.9.0.tgz 
cd rubygems-0.9.0 
sudo ruby setup.rb 
sudo gem install rails –include-dependencies

The apt-get commands will install the programming language Ruby, along with a number of modules that are required for Rails. The wget command downloads RubyGems, the ruby package manager similar to the built-in Ubuntu apt-get system. Finally, gems is used to install the Rails framework onto your computer.

And that's all there is to it! You will now have a shiny new Ruby on Rails installation on your computer. To create a new rails project, navigate into the directory you wish to place your application, and use this command:

Code:

rails mynewproject

You can find more information on Ruby on Rails at the official site (http://www.rubyonrails.org/), or you can check out the Rails Quick Reference (http://www.johnnysthoughts.com/rails-quick-reference/) over at Johnny's Thoughts.
