Bash script to install REDMINE on UBUNTU EC2 instance

Hi, I need a bash shell script to download and install (and uninstall), configure and autostart REDMINE on an existing EC2 instance already running apache with vhosts. The script should be compatible with the following: UBUNTU 10.10 EC2 instance APACHE2 - already running 2 other websites through vhosts MYSQL - already running 2 other databases JAVA - installed RUBY - passenger, not installed yet. Needs to be part of the script. Additional Requirements: Integrate Redmine installation to existing apache website @ [login to view URL] This will be done with Passenger and a new [login to view URL] or vhost file. I have created a repository at BITBUCKET as I would like access to the project in-flight. I can stand up an instance on AMAZON WEB SERVICES for the installation dev and testing once commenced. I already attempted this once, but fell short on a few things and I dont have the time now. This shouldnt take more than a few hours to dev and an hour to test, which I am happy to do myself. This will be the first of many such scripts as I am creating a set of SOE templates.
