How to create minecraft server on debian 12

Setting up a Minecraft server on Debian 12 allows you to host your own world, control player access, and enjoy smoother performance 

Step 1: Update Debian

Before installation, update your system packages to avoid compatibility issues:

sudo apt update && sudo apt upgrade -y

Step 2: Install Java

Minecraft requires Java to run. Debian 12 supports the latest OpenJDK version:

sudo apt install -y openjdk-21-jdk
java -version

Step 3: Create a Server Directory

Keep server files organized inside a dedicated folder:

mkdir ~/minecraft && cd ~/minecraft

Step 4: Download Minecraft Server

Get the official Minecraft server .jar file and save it in your directory:

wget https://launcher.mojang.com/v1/objects/server.jar -O minecraft_server.jar

Step 5: Accept EULA

Minecraft won’t start unless you accept the license agreement:

echo "eula=true" > eula.txt

Step 6: Start the Server

Now launch your server with Java. Adjust memory values (-Xmx and -Xms) based on your system resources:

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

Minecraft Server is now installed and running on Debian 12. The system is ready to host multiplayer worlds with full control over performance, settings, and player access.
