Installing RoR on Ubuntu 9.04

Mainly because I always forget... here's the quickest way to get Rails installed on a fresh Ubuntu box.
First, grab everything you need to install the native gems. Then most of the ruby stuff and mysql (it will ask you to choose a root password - don't forget what you pick)

sudo apt-get install build-essential
sudo apt-get install ruby ri rdoc mysql-server libmysql-ruby ruby1.8-dev irb1.8 libdbd-mysql-perl libdbi-perl libmysql-ruby1.8 libmysqlclient15off libnet-daemon-perl libplrpc-perl libreadline-ruby1.8 libruby1.8 mysql-client-5.0 mysql-common mysql-server-5.0 rdoc1.8 ri1.8 ruby1.8 irb libopenssl-ruby libopenssl-ruby1.8 libhtml-template-perl mysql-server-core-5.0 libmysqlclient-dev

Next, grab the latest rubygem from Rubyforge (http://rubyforge.org/projects/rubygems/)

wget http://rubyforge.org/frs/download.php/56227/rubygems-1.3.3.tgz
tar -zxvf rubygems-1.3.3.tgz
cd rubygems-1.3.3
sudo ruby setup.rb

At this point, do:

gem -v

Since this is a fresh install, you'll probably see something like:

slotito@ubuntu-desktop:~/rubygems-1.3.3$ gem -v
The program 'gem' can be found in the following packages:
 * rubygems1.8
 * rubygems1.9
Try: sudo apt-get install 
bash: gem: command not found

If you do, create some symlinks:

sudo ln -s /usr/bin/gem1.8 /usr/local/bin/gem
sudo ln -s /usr/bin/ruby1.8 /usr/local/bin/ruby
sudo ln -s /usr/bin/rdoc1.8 /usr/local/bin/rdoc
sudo ln -s /usr/bin/ri1.8 /usr/local/bin/ri
sudo ln -s /usr/bin/irb1.8 /usr/local/bin/irb

Ok, now for rails and some goodies =)

sudo gem install rails
sudo gem install mysql
sudo apt-get install imagemagick
sudo gem install rmagick
sudo gem install mongrel
