Setup Ruby on Rails on an Ubuntu Server

I am new to both Ubuntu and Ruby on Rails.  I am trying to setup Ruby on rails on an ubuntu 10.04 lts server.  What I would like to do is install ruby on rails and have it work with apache server and MySQL .  On the internet there are many different ways of doing this.  After trying to follow some of the guides, I start to get errors.

I would like to try to get the versions and successfully update the following technology on the Ubuntu Server:

Ruby, ruby gems, ruby on rails, apache and mysql.  

Also is there a quick way to to determine if all of the parts are configured and working together properly?

I admitting that i have no experience at all with any of these technologies, so if I am totally off base on my question, please let me know.  

My ultimate goal is to run a little ruby on rails development server where I can learn the language (as well as ubuntu.)  Maybe there is an excellent guide for getting on the interenet that I havent stumbled over yet.

TIA
