Setup Ruby on Rails 3 for development on Ubuntu 10.10 aka Maverick Meerkat

Installation on Ruby on Rails 3 on Ubuntu 10.10 is really easy peasy, However Ruby doesn't come pre-installed on Ubuntu like Python and Perl. To start of with installation of development tools for Rails we first need to install basic build tools like Compilers collection etc. There is handy packaged pre-built for that in Canonical repositories:

sudo apt-get install build-essential

Assuming you want to use My SQL server with Rails next we would need to setup Ruby, My SQL Server and Client as well as some other essential tools:

sudo apt-get install ruby ri rdoc irb ruby-dev libruby libreadline-ruby libopenssl-ruby mysql-client mysql-server libmysql-ruby libmysqlclient-dev

Now that Ruby and My SQL is setup We need to pull the latest version of Rubygems at run setup as a super user:

	cd ~
	mkdir gems
	cd gems
	wget http://production.cf.rubygems.org/rubygems/rubygems-1.5.1.tgz
	tar -xf rubygems-1.5.1.tgz
	cd rubygems-1.5.1
	sudo ruby setup.rb
	sudo ln -s /usr/bin/gem1.8 /usr/bin/gem
	sudo gem update system

In case you want to Sqlite 3 as development database with Rails 3 you may want to install that as well:

	sudo apt-get install sqlite3 libsqlite3-dev
	sudo gem install sqlite3-ruby
