Introduction
Minecraft is a well-liked sandbox video game. Initially launched in 2009, it permits gamers to build, discover, craft, and survive in a block 3D generated world. As of early 2022, it was the perfect-promoting video recreation of all time. On this tutorial, you'll create your personal Minecraft server so that you just and your friends can play together. Particularly, you will set up the necessary software program packages to run Minecraft, configure the server to run, after which deploy the sport.
Alternately, you possibly can discover DigitalOcean’s One-Click Minecraft: Java Version Server as another installation path.
This tutorial uses the Java version of Minecraft. Should hunter bought your model of Minecraft by means of the Microsoft App Retailer, you will be unable to connect with this server. Most variations of Minecraft purchased on gaming consoles such because the PlayStation 4, Xbox One, or Nintendo Change are also the Microsoft version of Minecraft. These consoles are also unable to hook up with the server built on this tutorial. You possibly can obtain the Java version of Minecraft here.
Conditions
So as to comply with this guide, you’ll want:
- A server with a fresh set up of Ubuntu 18.04, a non-root consumer with sudo privileges, and SSH enabled. You possibly can observe this guide to initialize your server and complete these steps. Minecraft may be resource-intensive, so keep that in thoughts when deciding on your server dimension. If you're utilizing DigitalOcean and need more assets, you may all the time resize your Droplet to add more CPUs and RAM.
- A duplicate of Minecraft Java Edition installed on a local Mac, Home windows, or Linux machine.
Step 1 - Putting in the mandatory Software Packages and Configure the Firewall
Along with your server initialized, your first step is to put in Java; you’ll want it to run Minecraft. By default, Ubuntu 18.04 doesn't provide a recent sufficient version of Java with a purpose to run the newest releases of Minecraft. Fortuitously, there are third-social gathering maintainers who proceed to build newer Java packages for older Ubuntu releases, and you can install them by including their PPA, or Private Package deal Archives, to your own list of bundle sources. You can do this with the following command:
sudo add-apt-repository ppa:openjdk-r/ppa
Subsequent, update your bundle sources to replicate this addition:
sudo apt replace
Finally, set up the OpenJDK version 17 of Java, particularly the headless JRE. It is a minimal model of Java that removes the help for GUI applications. This makes it superb for working Java applications on a server:
sudo apt install openjdk-17-jre-headless
You also want to make use of a software program referred to as display to create detachable server classes. screen means that you can create a terminal session and detach from it, leaving the process began on it running. This is vital as a result of in case you have been to start out your server and then close your terminal, this would kill the session and cease your server. Install display screen now:
sudo apt set up display screen
Now that you've the packages put in we need to enable the firewall to permit traffic to come in to our Minecraft server. In the preliminary server setup that you just performed you solely allowed ssh visitors. Now you want to allow for visitors to come in through port 25565, which is the default port that Minecraft makes use of to permit connections. In some cases ufw will use named traffic rules, equivalent to for ssh, which at all times makes use of port 22 by default, however in much less widespread circumstances like this one, we’ll specify the port number manually. Add the mandatory firewall rule by running the next command:
sudo ufw allow 25565
Now that you have Java installed and your firewall properly configured, you'll download the Minecraft server app from the Minecraft webpage.
Step 2 - Downloading the latest Version of Minecraft
Now it is advisable obtain the current version of the Minecraft server. You may 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 newest version 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 can be downloaded as server.jar. For those who ever have to handle versions of Minecraft, or if you want to upgrade 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, you could find them archived at mcversions.net. However this tutorial will deal with the present latest release. Now that you've got your obtain, let’s begin configuring your Minecraft server.
Step three - Configuring and Working the Minecraft Server
Now that you've got the Minecraft jar downloaded, you are ready to run it.
First, start a display screen session by operating the display command:
screen
Once you have read the banner that has appeared, press the Spacebar. display will current you with a terminal session like normal. This session is now detachable, which implies that you’ll be ready to start a command right here and go away it running.
You can now carry out your initial configuration. Don't be alarmed when the subsequent command throws an error. Minecraft has designed its installation this way in order that customers should first consent to the company’s licensing settlement. You will do that next:
1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar nogui
Before analyzing this command’s output, let’s take a more in-depth look at all these command-line arguments, that are tuning your server:
- Xms1024M - This configures the server to begin operating with 1024MB or 1GB of RAM working. You may elevate this restrict in order for you your server to start with extra RAM. Both M for megabytes and G for gigabytes are supported options. For instance: 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 possibly can raise this restrict if you would like your server to run at a larger dimension, enable for extra gamers, or if you're feeling that your server is running slowly. Java packages are distinctive in that they at all times require you to specify the maximum amount of memory they will 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 consumer interface.
The first time you run this command, which normally starts your server, you'll obtain this output:
These errors have been generated because the server couldn't find two crucial information required for execution: the EULA (Finish User License Settlement), found in eula.txt, and the configuration file server.properties. Since the server was unable to seek out these information, it created them in your present working directory. Minecraft does this deliberately to ensure that you've read and consented to its EULA.
Open eula.txt in nano or your favourite text editor:
nano eula.txt
Inside this file, you will note a link to the Minecraft EULA. Copy the URL:
Open the URL in your internet browser and skim the settlement. Then return to your text editor and find the last line in eula.txt. Here, change eula=false to eula=true. Then, save and shut the file. In nano, this means pressing “Ctrl+X” to exit, then when prompted to save lots of, “Y”, then Enter.
Now that you’ve accepted the EULA, you possibly can configure the server to your specs.
In your current working directory, additionally, you will discover the newly created server.properties file. This file comprises all of the configuration options for your Minecraft server. You could find an in depth listing of all server properties on the Official Minecraft Wiki. It is best to modify this file together with your preferred settings earlier than beginning your server. This tutorial will cowl some fundamental settings:
nano server.properties

- pvp (default true) - Enables Participant versus Player fight. If set to true, players can be in a position to engage in combat and harm one another.
After you have set the choices that you really want, save and shut the file.
Now you possibly can successfully start your server.
Like last time, let’s start your server with 1024M of RAM. This time, you should also grant Minecraft the flexibility to make use of as much as 4G of RAM if needed. Remember, you're welcome to adjust this quantity to suit your server limitations or user needs:
1. java -Xms1024M -Xmx4G -jar minecraft_server_1.18.1.jar nogui
Give the initialization a couple of moments. Quickly your new Minecraft server will begin producing an output just like this:
Once the server is up and running, you will see the following output:
Your server is now working, and you have been offered with the server administrator control panel. Try typing help:

Run this command to see your whole display screen sessions:
display screen -checklist
You’ll get an output with the ID of your session, which you’ll need to resume that session:
To resume your session, move the -r flag to the display command and then enter your session ID:
display -r 3626
When you are able to log out of the terminal again, be sure you detach from the session with Ctrl + A + D and then log out.
