From Pi My Life Up:
In this tutorial we will be showing you how to setup your very own Raspberry Pi Minecraft PE server. This is a cheap way of providing you with an always on, Pocket Edition capable server.
This stops you from having to leave your phone or computer online if you want others to be able to always access your world. The Pi is also pretty good on power usage so you can save on your power bill too.
