Voici ce que j'ai récupéré du post de mon blog:
1) Install Ruby
sudo apt-get install ruby rdoc irb libyaml-ruby libzlib-ruby ri
2) Install RubyGems
wget http://rubyforge.org/frs/download.php/29548/rubygems-1.0.1.tgz
tar xzvf rubygems-1.0.1.tgz
cd rubygems-1.0.1
export GEM_HOME=$HOME/lib/ruby/gems/1.8
export RUBYLIB=$HOME/lib:/usr/lib/ruby/1.8
ruby setup.rb all –prefix=$HOME
You should then add GEM_HOME and RUBYLIB into your ~/.profile file to automatically load on login (otherwise some scripts will complain of not finding rubygems).
You should append $HOME/bin and $HOME/lib/ruby/gems/1.8/bin to your PATH defined in your ~/.profile file.
3) Install Rails and it's dependencies (with RubyGems)
~/bin/gem install rails -y
Here is a good time to install any gems you may need like mongrel and MySQL below.
To install mongrel, you can do the following:
sudo apt-get install build-essential
sudo apt-get install ruby1.8-dev
gem install mongrel
If you would like to install the mysql gem,
sudo apt-get install libmysqlclient15-dev
then run
gem install mysql
4) Create your first Rails app, as the current user (i.e., no sudo):
$ ~/lib/ruby/gems/1.8/bin/rails /path/to/new/railsapp
Of course, replace /path/to/new/railsapp with the path to the location where you'd like the source code for your new Rails application to exist. This can be /home/myhome/rails/myapp.
