This tutorial makes use of the Java version of Minecraft. In the event you purchased your model of Minecraft by way of the Microsoft App Retailer, you will be unable to connect to this server. Most versions of Minecraft bought on gaming consoles such because the PlayStation 4, Xbox One, or Nintendo Change are additionally the Microsoft model of Minecraft. These consoles are additionally unable to connect with the server built on this tutorial. You may obtain the Java version of Minecraft right here.
Prerequisites
To be able to comply with this guide, you’ll want:
- A server with a contemporary set up of Ubuntu 18.04, a non-root user with sudo privileges, and SSH enabled. You possibly can follow this guide to initialize your server and full these steps. Minecraft might be resource-intensive, so keep that in thoughts when selecting your server measurement.

- A duplicate of Minecraft Java Version put in on a local Mac, Windows, or Linux machine.
Step 1 - Putting in the mandatory Software program Packages and Configure the Firewall
Along with your server initialized, your first step is to put in Java; you’ll need it to run Minecraft. By default, Ubuntu 18.04 doesn't present a recent enough model of Java so as to run the most recent releases of Minecraft. Fortuitously, there are third-party maintainers who continue to build newer Java packages for older Ubuntu releases, and you can set up them by adding their PPA, or Personal Package Archives, to your own list of package sources. You can do this with the next command:
sudo add-apt-repository ppa:openjdk-r/ppa
Subsequent, update your bundle sources to mirror this addition:
sudo apt update
Finally, install the OpenJDK version 17 of Java, specifically the headless JRE. This is a minimal version of Java that removes the help for GUI functions. This makes it best for running Java purposes on a server:
sudo apt install openjdk-17-jre-headless
You additionally want to make use of a software program referred to as screen to create detachable server classes. display means that you can create a terminal session and detach from it, leaving the method began on it running. This is important because if you had been to start out your server and then shut your terminal, this could kill the session and stop your server. Set up display screen now:
sudo apt set up screen
Now that you've got the packages installed we have to enable the firewall to allow traffic to come in to our Minecraft server. In the preliminary server setup that you simply performed you only allowed ssh traffic. Now you need to allow for site visitors to come in by way of port 25565, which is the default port that Minecraft makes use of to permit connections. In some cases ufw will use named visitors guidelines, comparable to for ssh, which all the time uses port 22 by default, however in less frequent instances like this one, we’ll specify the port quantity manually. Add the mandatory firewall rule by operating the next command:
sudo ufw allow 25565
Now that you've Java installed and your firewall properly configured, you will download the Minecraft server app from the Minecraft web site.
Step 2 - Downloading the latest Model of Minecraft
Now you must download the present model of the Minecraft server. You may do this by navigating to Minecraft’s Webpage and copying the link that says Download minecraft_server.X.X.X.jar, where the X’s are the latest model of the server.
You can now use wget and the copied hyperlink to download the server app to your server:
wget https://launcher.mojang.com/v1/objects/125e5adf40c659fd3bce3e66e67a16bb49ecc1b9/server.jar
The server app shall be downloaded as server.jar. In case you ever have to manage versions of Minecraft, or if you want to improve your Minecraft server, it could also be helpful to rename the downloaded server.jar to minecraft_server_1.18.1.jar, matching the highlighted model numbers to no matter model you just downloaded:
mv server.jar minecraft_server_1.18.1.jar
If you wish to obtain an older model of Minecraft, you'll find them archived at mcversions.internet. But this tutorial will give attention to the present newest launch. Now that you've your obtain, let’s start configuring your Minecraft server.

1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar nogui
Before inspecting this command’s output, let’s take a better look at all these command-line arguments, that are tuning your server:
- Xms1024M - This configures the server to start working with 1024MB or 1GB of RAM operating. You'll be able to increase this limit if you'd like your server to start out with more RAM. Each M for megabytes and G for gigabytes are supported choices. For instance: Xms2G will start the server with 2 gigabytes of RAM.
- Xmx1024M - This configures the server to use, at most, 1024M of RAM. You may increase this restrict in order for you your server to run at a bigger dimension, enable for extra players, or if you feel that your server is running slowly. Java packages are distinctive in that they always require you to specify the utmost amount of memory they can use.
- jar - This flag specifies which server jar file to run.
- nogui - This tells the server to not launch a GUI since it is a server, and also you don’t have a graphical person interface.

In your present working directory, you will also find the newly created server.properties file. This file contains all the configuration options for your Minecraft server. You will discover an in depth listing of all server properties on the Official Minecraft Wiki. You need to modify this file together with your most popular settings earlier than beginning your server. This tutorial will cowl some elementary settings:

Now you possibly can successfully begin your server.
Like final time, let’s start your server with 1024M of RAM. This time, you also needs to grant Minecraft the ability to make use of up to 4G of RAM if crucial. Remember, you might be welcome to adjust this number to suit your server limitations or user wants:
1. java -Xms1024M -Xmx4G -jar minecraft_server_1.18.1.jar nogui
Give the initialization just a few moments. Soon your new Minecraft server will begin producing an output just like this:
As soon as the server is up and operating, you will note the following output:
Your server is now operating, and you have been introduced with the server administrator control panel. Try typing help:
