Introduction
Minecraft is a well-liked sandbox video recreation. Initially released in 2009, it permits players to construct, discover, craft, and survive in a block 3D generated world. As of early 2022, it was one of the best-promoting video recreation of all time. In this tutorial, you'll create your own Minecraft server so that you just and your folks can play collectively. Specifically, you'll install the necessary software packages to run Minecraft, configure the server to run, and then deploy the sport.
Alternately, you possibly can discover DigitalOcean’s One-Click on Minecraft: Java Edition Server as one other installation path.
This tutorial uses the Java model of Minecraft. When you bought your model of Minecraft by the Microsoft App Store, you can be unable to connect with 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 built in this tutorial. You'll be able to obtain the Java model of Minecraft here.
Stipulations
With a view to observe this guide, you’ll need:
- A server with a recent installation of Ubuntu 18.04, a non-root person with sudo privileges, and SSH enabled. You may follow this guide to initialize your server and complete these steps. Minecraft could be useful resource-intensive, so keep that in mind when deciding on your server measurement. If you are utilizing DigitalOcean and need extra sources, you can at all times resize your Droplet so as to add more CPUs and RAM.
- A copy of Minecraft Java Version installed on an area Mac, Windows, or Linux machine.
Step 1 - Putting in the necessary Software Packages and Configure the Firewall
With your server initialized, your first step is to install Java; you’ll want it to run Minecraft. By default, Ubuntu 18.04 does not provide a recent enough version of Java in an effort to run the most recent releases of Minecraft. Happily, there are third-social gathering maintainers who continue to construct newer Java packages for older Ubuntu releases, and you may install them by adding their PPA, or Private Package deal Archives, to your personal record of package sources. You'll be able to do this with the following command:
sudo add-apt-repository ppa:openjdk-r/ppa
Subsequent, update your bundle sources to reflect this addition:
sudo apt replace
Lastly, set up the OpenJDK model 17 of Java, specifically the headless JRE. It is a minimal model of Java that removes the assist for GUI functions. This makes it perfect for working Java applications on a server:
sudo apt set up openjdk-17-jre-headless
You additionally want to make use of a software program referred to as screen to create detachable server periods. screen allows you to create a terminal session and detach from it, leaving the process started on it operating. This is important as a result of if you happen to were to begin your server after which shut your terminal, this may kill the session and stop your server. Set up display screen now:
sudo apt set up screen
Now that you have the packages put in we have to enable the firewall to allow site visitors to are available to our Minecraft server. Within the preliminary server setup that you simply carried out you solely allowed ssh site visitors. 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 instances ufw will use named traffic guidelines, reminiscent of for ssh, which at all times makes use of port 22 by default, however in much less widespread cases like this one, we’ll specify the port quantity manually. Add the necessary firewall rule by running the next command:
sudo ufw allow 25565
Now that you have Java put in 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 might want to obtain the present version of the Minecraft server. You'll be able to do this by navigating to Minecraft’s Website and copying the link that says Download minecraft_server.X.X.X.jar, the place the X’s are the latest model of the server.
Now you can use wget and the copied link 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. If you ever must handle versions of Minecraft, or if you wish to improve your Minecraft server, it may be useful to rename the downloaded server.jar to minecraft_server_1.18.1.jar, matching the highlighted version numbers to no matter version you just downloaded:
mv server.jar minecraft_server_1.18.1.jar
If you wish to obtain an older model of Minecraft, you will discover them archived at mcversions.net. But this tutorial will deal with the current latest launch. Now that you have your download, let’s start configuring your Minecraft server.
Step three - Configuring and Operating the Minecraft Server
Now that you have the Minecraft jar downloaded, you might be ready to run it.
First, start a display screen session by running the display screen command:
display
Once you have read the banner that has appeared, press the Spacebar. display will current you with a terminal session like regular. This session is now detachable, which signifies that you’ll be in a position to start out a command right here and leave it working.
You can now carry out your preliminary configuration. Don't be alarmed when the following command throws an error. Minecraft has designed its set up this manner so that customers 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
Before analyzing this command’s output, let’s take a closer look at all these command-line arguments, that are tuning your server:
- Xms1024M - This configures the server to start out operating with 1024MB or 1GB of RAM operating. You can increase this restrict if you need your server to start out with more RAM. Both M for megabytes and G for gigabytes are supported options. For example: Xms2G will begin the server with 2 gigabytes of RAM.
- Xmx1024M - This configures the server to use, at most, 1024M of RAM. You'll be able to raise this limit in order for you your server to run at a larger dimension, permit for more gamers, or if you feel that your server is running slowly. Java programs are distinctive in that they at all times require you to specify the utmost quantity of memory they'll use.
- jar - This flag specifies which server jar file to run.
- nogui - This tells the server not to launch a GUI since this is a server, and also you don’t have a graphical user interface.
The primary time you run this command, which normally begins your server, you will receive this output:
These errors were generated as a result of the server could not find two necessary recordsdata required for execution: the EULA (End User License Agreement), present in eula.txt, and the configuration file server.properties. Because the server was unable to seek out these recordsdata, it created them in your present working listing. Minecraft does this deliberately to make sure that you have read and consented to its EULA.
Open eula.txt in nano or your favourite textual content editor:
nano eula.txt
Inside this file, you will note a link to the Minecraft EULA. Copy the URL:
Open the URL in your web browser and skim the settlement. Then return to your text editor and find the final line in eula.txt. Right here, change eula=false to eula=true. Then, save and shut the file. In nano, this means urgent “Ctrl+X” to exit, then when prompted to save lots of, “Y”, then Enter.
Now that you’ve accepted the EULA, you may configure the server to your specifications.
In your current working listing, you will also discover the newly created server.properties file. Minecraft servers This file accommodates all the configuration choices in your Minecraft server. You could find a detailed list of all server properties on the Official Minecraft Wiki. You must modify this file along with your most popular settings earlier than beginning your server. This tutorial will cowl some elementary settings:
nano server.properties
Your file will seem like this:
Let’s take a better have a look at some of crucial properties on this list:
- problem (default straightforward) - This sets the difficulty of the sport, such as how a lot injury is dealt and how the elements affect your player. The choices are peaceful, simple, regular, and laborious.

- pvp (default true) - Allows Player versus Participant combat. If set to true, players shall be able to engage in combat and harm each other.
Once you have set the choices that you want, save and shut the file.
Now you can efficiently start your server.
Like last time, let’s start your server with 1024M of RAM. This time, you should also grant Minecraft the power to use as much as 4G of RAM if needed. Remember, you're welcome to regulate this number to suit your server limitations or consumer needs:
1. java -Xms1024M -Xmx4G -jar minecraft_server_1.18.1.jar nogui
Give the initialization a few moments. Soon your new Minecraft server will start producing an output similar to this:
As soon as the server is up and running, you will note the following output:
Your server is now working, and you've got been offered with the server administrator management panel. Attempt typing help:
help
Output like this can seem:
From this terminal you may run administrator commands and management your Minecraft server. Now you’ll study to use display screen to keep your Minecraft server working after you log out of the terminal. Then you possibly can hook up with your Minecraft consumer and start a brand new game.
Step four - Protecting the Server Running

Run this command to see all your display sessions:
display -checklist
You’ll get an output with the ID of your session, which you’ll have to resume that session:
To resume your session, move the -r flag to the display command after which enter your session ID:
screen -r 3626
If you find yourself ready to log out of the terminal once more, be sure to detach from the session with Ctrl + A + D and then log out.
Step 5 - Connecting to Your Server from the Minecraft Shopper
Now that your server is up and operating, let’s connect with it through the Minecraft client. Then you may play!
