Build a Minecraft Server on RaspberryPi 4 (linuxnorth.org)

[Paper Edition]

1. Install Java

sudo apt install openjdk-21-jre

2. Paper Downloads | PaperMC

java -jar paper-1.21.1-52.jar --nogui

3. 

Setup | GeyserMC

Place the Geyser-Spigot.jar in the plugins folder, and restart the server.

Open your Geyser config, located in /plugins/Geyser-Spigot/config.yml, and find the following:
bedrock: 
    # The IP address that will listen for connections. 
    # Generally, you should only uncomment and change this if you want to limit what IPs can connect to your server. 
    #address: 0.0.0.0 

    # The port that will listen for connections. This is the port that Bedrock players will use to connect to your server.
    port: 19132
