Set up a Minecraft SMP server on Ubuntu. Automatically installs Java, creates a minecraft user, pulls in the latest minecraft_server.jar, and writes a script to automatically start the server. Read the comments in the script for more information.
Following script works on the following OS: Ubuntu 10.04 LTS|Ubuntu 10.10|Ubuntu 9.10
You can download it here or see below for the details.

This server has been deployed from Jed Smith's Minecraft StackScript. To start
Minecraft, run the following as root:
# su - minecraft -s /opt/minecraft/run.sh
screen is also installed if you prefer to run Minecraft in a screen. It is a
very bad idea to run the Minecraft server as root; although there are no
currently-known vulnerabilities, you're better off insulating your server.
All files related to the server are in /opt/minecraft.
