I am currently installing Ubuntu Server 10.04 in a virtual machine and I am going to run my web app in it so I can see how it runs, etc in a 'production' environment.
What software should be installed and what is the common software/packages installed when hosting a Rails app?
In my real production environment, I am running Ubuntu Server 10.04 64bit, Apache2, PHP5, MySQL and am using Virtualmin to manage the setup on these sites, therefore I want it to imitate the real production web server as it will be deployed to that when the app is ready.
I have installed Passenger on my real production web server. I am just looking for software that I should install in my clean Ubuntu Server.
EDIT: Also is it recommended to use RVM in production?
