FIXME 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.
