This article explains the steps to install Minecraft cloud gaming servers on Ubuntu 20.04.
Create a sudo user named minecraft.
# adduser minecraft # usermod -aG sudo minecraft
Switch to the new user.
# su - Minecraft
Update the package index.
$ sudo apt update
$ sudo apt install openjdk-16-jdk -y
Install Screen. This allows your server to run without leaving your terminal open.
$ sudo apt install screen -y
Confirm the installed packages.
$ sudo java -version
Create a new server directory for your server files.
$ mkdir minecraft
Move to the directory.
$ cd minecraft
$ sudo apt install wget
Navigate to https://www.minecraft.net/en-us/download/server to find the download links for the latest version of Minecraft. Download it with
wget. For example, with version 1.16.4`, run:
$ sudo wget https://launcher.mojang.com/v1/objects/35139deedbd5182953cf1caa23835da59ca3d7cd/server.jar
Run the server. The
1024M parameter in
-Xms1024M -Xmx1024M configures Java for 1 GB of RAM. Change this to the amount of RAM you want to allocate for Minecraft. The operating system requires available RAM as well, please don't assign all available RAM to Minecraft. For example, if the server has 4 GB RAM, you might consider setting
$ java -Xmx1024M -Xms1024M -jar server.jar nogui
You should receive an similar output to this.
[main/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.
To agree to the EULA, edit eula.txt.
$ sudo nano eula.txt
Find the line that says
eula=false and change it to
eula=true. Save and exit the file.
Create a startup script for your server.
$ nano start.sh
Paste the following into start.sh. Adjust the
Xms RAM values as needed.
#!/bin/sh while true do java -Xmx1024M -Xms1024M -jar server.jar nogui echo "restarting in 10" sleep 10 done
Save and exit the file.
$ chmod +x start.sh
Create a screen instance for the server.
$ sudo screen -S "Minecraft Server"
Start your server script.
To exit the screen session, press CTRL + A then D. To resume the screen session, run:
$ sudo screen -R
Here are some tips for your Minecraft server:
You can use Minecraft commands in the screen session without a leading
/. For example
op @a will make everybody online a server operator.
To modify the general game settings for your Minecraft server, input the command
sudo nano server.properties to get access to them.
The Minecraft server creates a new directory called
world on the first launch for Minecraft modifications, datapacks, and other features.
