RockPro64 with DietPi as a Minecraft server

RockPro64 as a Minecraft server is a great idea. It’s small, energy-efficient, quiet, and above all, sufficient for having fun with a few friends.

I have two RockPro64 boards at home. I use one as a Matrix server (Synapse) and as a personal cloud (Nextcloud). The other one remained unused for a while until the idea came to play Minecraft with friends.

I chose the DietPi operating system. I must confess that I haven’t checked how the Minecraft server performs on Armbian or Manjaro, but if you’ve tried, please share your experiences in the comments. DietPi can be downloaded from here: After downloading the image and writing it to a microSD card, you can start up your future server.

There is a lot of Minecraft server software available on the internet. In the DietPi repository, there are two options that can be installed using DietPi-Software: Cuberite and MineOS.

DietPi-Software, a tool that allows us to easily install additional software.

Unfortunately, both support older versions of Minecraft. Therefore, the choice fell on external software: Fabric.

On the website, you can download the Minecraft Server Launcher. Simply choose the Minecraft Version, Fabric Loader Version, and Installer Version to download a specially prepared Java *.jar file, which you then run on your server. For example:

nohup java -Xmx4G -jar fabric-server-mc.1.20.1-loader.0.14.24-launcher.0.11.2.jar nogui

nohup is a command used to run another program in a way that it won’t be terminated when logging out.

When you start the server, you may notice a high consumption of CPU resources. All you need to do is slightly overclock your system, change the CPU governor and tweak your ARM temperature limits.

Just run dietpi-config to easily change your hardware settings: dietpi-config -> Performance Options.

Thanks to this, the average CPU usage with several users will oscillate around 10-15%.

After starting your Minecraft server, remember to port forward on your router, unless you are only using the server within your local network. The Minecraft server runs on port 25565
