A couple of weeks ago there was a post on the FiveRuns blog about automatically installing the Rails stack on an Ubuntu 8.04 VPS.
I prefer to use Passenger and Ruby Enterprise Edition when running my Rails app, so inspired by the FiveRuns script I wrote my own version - here is the gist on github.
#!/bin/bash

apt-get update
apt-get upgrade -y
apt-get -y install build-essential libssl-dev libreadline5-dev zlib1g-dev
apt-get -y install mysql-server libmysqlclient15-dev mysql-client
apt-get -y install ruby ruby1.8-dev irb ri rdoc libopenssl-ruby1.8
RUBYGEMS=”rubygems-1.3.0″
wget http://rubyforge.org/frs/download.php/43985/$RUBYGEMS.tgz
tar xzf $RUBYGEMS.tgz
cd $RUBYGEMS

cd ..

The script assumes that you have ssh access as root to a clean Ubuntu 8.04 install.
The script will install
- Ruby 1.8.6
- RubyGems 1.3.0
- Passenger 2.0.3
- Ruby Enterprise Edition 20080810
- Apache 2.2.8
- MySQL 5.0.51a
- A sample Rails app
Note that the Passenger installer will install the latest Rails (2.1.1) and a bunch of other useful gems.
Assuming that your server IP address is 192.168.185.128 you can run it like this:
ssh root@192.168.185.128 “wget -O - http://gist.github.com/raw/16225/a6a16b3a38cd3486679b96fa0f3446e58f3b8423 | sed -e s/$’\r’//g > install.sh; /bin/bash install.sh; rm install.sh”
Sit back and enjoy - in less than ten minutes you will have the full Rails stack and a sample Rails app running. Take a look at it on http://192.168.185.128/welcome/hello
