Here are a list of commands to get up and running with Apache2 with Phussion Passenger for Rails, PHP5, MySQL5, Ruby on Rails with Gems, and the source control software Git. I think that this is a pretty ideal environment for a development box and even production if you need to run apps that are written in both PHP and Ruby.

I'm using Ubuntu 8, Hardy Heron in this example.

Login to your server as root, sudo su, if you're on the box already as another user. You can optionally enter the sudo command before each of the following commands but I don't in this example. If you get a permission denied error, try the same command again with sudo in front of it.

The following will update where Ubuntu looks for packages, upgrade to the latest stable build and also install build tools like gcc and make.

apt-get update
apt-get upgrade
apt-get install build-essential
Now that the server is up to date and has the necessary tools to build and compile the software we're about to install, let's intstall our basic LAMP (Linux, Apache2, MySQL and PHP) stack. You can list different packages to install sequentialy if you separate them with a space.
apt-get install apache2 apache2-prefork-dev
apt-get install mysql-client mysql-server
apt-get install php5 php5-mysql
Lets get Ruby installed next. We will want to use Ruby Gems to manage our Ruby packages rather than apt-get. The reason is because apt-get doesn't keep up with the latest stable for all Ruby packages and Gems is really a great way to manage Ruby libraries. Think of Ruby Gems as apt-get but for Ruby. Rails for example is a Ruby library that we will download and install using Gems. However, to install Gems we need Ruby and we get Ruby using apt-get.
apt-get install ruby ruby1.8-dev libopenssl-ruby ri rdoc
This should download and install Ruby with a couple of other packages for documentation and SSL support. To get Gems we need to download either a zip or tgz. The best way and easiest way is to navigate to http://rubyforge.org and search for rubygems(one word).

Here is a link to the exact package that I have downloaded and used for this information.

However, this could change in the future or when Gems gets an upgrade.

You need to get it on your server. You can either download it to your local machine and ftp or scp it to your remote server or you can use a tool like wget to download directly to your server.

wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz
If you don't have wget installed, which would be odd, just type apt-get install wget

After it has finished downloading unpack it and cd into it *the name below will be different .

tar xzvf <rubygems-dowloaded-file.tgz>
After you cd into the folder type
ruby setup.rb
You'll install new Gems with the command gem install package-name. However, now you need to link the program you just downloaded to /usr/bin/gem. The reason is that Gems was installed but with a version number suffix like /usr/bin/gem1.8 or whatever version it's at. The reason for this is so that you can switch between different versions of Gems without having to uninstall anything. Just override the old link and you can use the new Gem. So to link the file you'll need to find the path that it was installed under, most likely /usr/bin/gem1.8. Once you have the path type in the terminal
ln -s /usr/bin/<your gem version> /usr/bin/gem
Where <your gem version> is something like gem1.8

Type gem --version to verify that it works. You'll get a readout of the version of the Gem you are using. Next let's get it up to date and install the Rails framework. That is two dashes for the system flag below.

gem update --system
gem install rails
Once that is done we'll want to install Phusin Passenger which will let us deploy our Rails application in a similar fashion to any PHP based application. Just point a VirtualHost DocumentRoot to the location of your Rails_Root/public directory and your're good to go!
gem install passenger
Next we'll build and compile the module for Apache. This is why we needed to run apt-get install build-essential, installing passenger requires make and gcc development tools. When you execute the next command it will spit a lot of stuff to the screen. This is normal, it is building and linking the module for you. When it is done it will tell you what to copy and paste. I will too, but your configuration could be slightly different. Just follow the prompts that follow.
Passenger will tell you where to put the configuration options. It will look something like this
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.0.5/ext/apa$
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.0.5
PassengerRuby /usr/bin/ruby1.8
I placed the code above into the /etc/apache2/mods-available/passenger.conf then I linked them to the mods available directory like so ln -s /etc/apache2/mods-available/passenger.conf /etc/apache2/sites-enables/passenger.conf

Next create a VirtualHost

<VirtualHost *>
  ServerName awesome.iam.com
  DocumentRoot /var/www/awesome.iam.com/public
  RailsEnv production
Remember to restart your server with
apache2ctl restart
Also, you restart your Rails application by issuing this command from the Rails_Root dir
touch tmp/restart.txt
And finally, to install Git
apt-get install git git-core
