Installing Rails 3 in Ubuntu 10.04

As I am exploring different languages and platforms for web development, I have encountered(a few months ago) ruby on rails. It has impressed me so much that I wanted to create a virtual development environment for it. For the base I choose Ubuntu 10.04 LTS which is a great distribution for *nix beginners. We will install everything we need for a slick and updateable ruby on rails development machine.

I will just copy/paste the script I have made, notice that git version may change.

#Install git

# 1. First we install the dependent packages, thus you wont have to install # the packages yourself.

sudo aptitude build-dep git-core

# 2. Download latest stable GIT release from here

wget http://kernel.org/pub/software/scm/git/git-1.7.2.tar.gz

# 3. Extract the archive and change to the extracted directory

tar xvzf git-1.7.2.tar.gz
cd git-1.7.2/

# 4. Run the following

./configure && make
sudo make install

#5. Check installation and clean up

git --version
cd ../;rm -r git-1.7.2 git-1.7.2.tar.gz

#install curl
sudo apt-get install curl

#install rvm

bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )

#Then add this line as the last line in your .bashrc:

if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then source "$HOME/.rvm/scripts/rvm" ; fi

#install rvm dependencies

sudo apt-get install bison build-essential zlib1g zlib1g-dev libssl-dev libreadline5-dev libreadline6-dev libxml2-dev git-core subversion autoconf

#install ruby
rvm update
rvm install 1.9.2
rvm 1.9.2 --default
#test ruby version
ruby -v
# install rails 3.0.4
gem install rails

gem update --system
gem update

This is for a single user installation, like you would have at your home/work computer, for a server installation, you should install rvm as superuser so it will install rvm into /user/local/rvm

EDIT: There is an easier way to do this, as described on: Rails Ready

It is an automated script that does all of this for you
