Cheat Sheet - what do you need for Ruby on Rails?

Here is a "cheat sheet" of the commands you might use to install Ruby, then Gems, then Rails, then get your first application and server running.

1. Ruby

tar xf ruby-1.9.1-p376.tar.gz

cd ruby-1.9.1-p376/

./configure

make

make install

Check installation:

[root@easterton ruby-1.9.1-p376]# ruby -v

ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]

[root@easterton ruby-1.9.1-p376]#

2. Ruby Gems

RubyGems is a sophisticated package manager for Ruby.
See http://docs.rubygems.org/ ...
Set up gems once you've installed Ruby via:

ruby setup.rb

3. Rails

gem install rails

4. Create a framework for your first application

rails path/to/your/new/application

5. Start the server

cd path/to/your/new/application

ruby script/server

Check installation:

Browse to http://localhost:3000/
