Introduction
Minecraft is a well-liked sandbox video sport. Initially launched in 2009, it permits gamers to construct, explore, craft, and survive in a block 3D generated world. As of early 2022, it was the very best-selling video sport of all time. In this tutorial, you'll create your own Minecraft server so that you simply and your folks can play collectively. Specifically, you'll install the mandatory software program packages to run Minecraft, configure the server to run, and then deploy the game.
Alternately, you'll be able to discover DigitalOcean’s One-Click on Minecraft: Java Version Server as one other installation path.
This tutorial uses the Java model of Minecraft. When you bought your model of Minecraft through the Microsoft App Retailer, you'll be unable to connect to this server. Most variations of Minecraft purchased on gaming consoles such as the PlayStation 4, Xbox One, or Nintendo Switch are also the Microsoft model of Minecraft. These consoles are additionally unable to hook up with the server constructed on this tutorial. You possibly can acquire the Java version of Minecraft here.
Prerequisites
As a way to comply with this information, you’ll want:
- A server with a contemporary installation of Ubuntu 18.04, a non-root consumer with sudo privileges, and SSH enabled. You possibly can observe this information to initialize your server and complete these steps. Minecraft might be useful resource-intensive, so keep that in mind when choosing your server dimension. In case you are utilizing DigitalOcean and want more sources, you can always resize your Droplet so as to add more CPUs and RAM.
- A copy of Minecraft Java Version put in on an area Mac, Windows, or Linux machine.
Step 1 - Installing the mandatory Software Packages and Configure the Firewall
Together with your server initialized, your first step is to put in Java; you’ll want it to run Minecraft. By default, Ubuntu 18.04 does not provide a recent enough model of Java with a view to run the newest releases of Minecraft. Fortuitously, there are third-occasion maintainers who continue to build newer Java packages for older Ubuntu releases, and you'll set up them by adding their PPA, or Private Package Archives, to your personal record of package sources. You may do this with the next command:
sudo add-apt-repository ppa:openjdk-r/ppa
Subsequent, replace your bundle sources to replicate this addition:
sudo apt replace
Lastly, set up the OpenJDK version 17 of Java, specifically the headless JRE. It is a minimal model of Java that removes the support for GUI purposes. This makes it supreme for working Java applications on a server:
sudo apt install openjdk-17-jre-headless
You additionally need to use a software program referred to as display to create detachable server classes. display means that you can create a terminal session and detach from it, leaving the process started on it operating. This is important because should you had been to start out your server after which shut your terminal, this may kill the session and stop your server. Install screen now:
sudo apt set up display
Now that you've got the packages put in we need to enable the firewall to allow visitors to are available in to our Minecraft server. Within the initial server setup that you simply carried out you solely allowed ssh site visitors. Now you need to allow for traffic to are available in through port 25565, which is the default port that Minecraft makes use of to permit connections. In some cases ufw will use named site visitors guidelines, such as for ssh, which always uses port 22 by default, however in much less widespread cases like this one, we’ll specify the port number manually. Add the required firewall rule by running the next command:
sudo ufw allow 25565
Now that you've Java put in and your firewall correctly configured, you will download the Minecraft server app from the Minecraft web site.
Step 2 - Downloading the latest Model of Minecraft
Now it's worthwhile to obtain the present version of the Minecraft server. You can do this by navigating to Minecraft’s Website and copying the hyperlink that says Download minecraft_server.X.X.X.jar, where the X’s are the most recent model of the server.
You can now use wget and the copied hyperlink to obtain the server app to your server:
wget https://launcher.mojang.com/v1/objects/125e5adf40c659fd3bce3e66e67a16bb49ecc1b9/server.jar
The server app can be downloaded as server.jar. In case you ever must manage versions of Minecraft, or if you want to improve your Minecraft server, it may be helpful to rename the downloaded server.jar to minecraft_server_1.18.1.jar, matching the highlighted version numbers to whatever model you simply downloaded:
mv server.jar minecraft_server_1.18.1.jar
If you want to obtain an older version of Minecraft, yow will discover them archived at mcversions.net. However this tutorial will give attention to the present latest release. Now that you have your download, let’s begin configuring your Minecraft server.

First, start a screen session by working the display command:
display
Upon getting learn the banner that has appeared, press the Spacebar. display will present you with a terminal session like regular. This session is now detachable, which means that you’ll be ready to start out a command here and go away it operating.
You can now carry out your initial configuration. Do not be alarmed when the following command throws an error. Minecraft has designed its set up this fashion so that users must first consent to the company’s licensing agreement. You'll do that subsequent:
1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar nogui
Earlier than examining this command’s output, let’s take a more in-depth look at all these command-line arguments, which are tuning your server:
- Xms1024M - This configures the server to start running with 1024MB or 1GB of RAM running. You'll be able to raise this limit if you want your server to start out with extra RAM. Each M for megabytes and G for gigabytes are supported options. For example: Xms2G will start the server with 2 gigabytes of RAM.
- Xmx1024M - This configures the server to make use of, at most, 1024M of RAM. You may raise this restrict if you'd like your server to run at a bigger measurement, allow for extra gamers, or if you feel that your server is running slowly. Java programs are unique in that they always require you to specify the maximum amount of memory they'll 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 you don’t have a graphical person interface.
The primary time you run this command, which normally begins your server, you will receive this output:
These errors were generated because the server could not find two needed information required for execution: the EULA (End User License Agreement), found in eula.txt, and the configuration file server.properties. Since the server was unable to search out these information, it created them in your present working listing. Minecraft does this intentionally to make sure that you've learn and consented to its EULA.

Now that you’ve accepted the EULA, you'll be able to configure the server to your specifications.
In your present working directory, additionally, you will find the newly created server.properties file. This file comprises the entire configuration options on your Minecraft server. Yow will discover an in depth list of all server properties on the Official Minecraft Wiki. You need to modify this file together with your preferred settings earlier than beginning your server. This tutorial will cover some fundamental settings:
nano server.properties

Once you have set the options that you really want, save and shut the file.
Now you possibly can successfully begin your server.
Like last time, let’s start your server with 1024M of RAM. This time, you also needs to grant Minecraft the ability to make use of as much as 4G of RAM if vital. Remember, you are welcome to regulate this quantity to suit your server limitations or person 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 start producing an output similar to this:
Once the server is up and running, you will see the following output:
Your server is now running, and you've got been presented with the server administrator management panel. Strive typing assist:
