Most variations of Minecraft bought on gaming consoles such because the PlayStation 4, Xbox One, or Nintendo Change are also the Microsoft version of Minecraft. These consoles are additionally unable to connect to the server constructed on this tutorial. You'll be able to obtain the Java model of Minecraft here.


Stipulations


In order to comply with this information, you’ll need:


- A server with a fresh installation of Ubuntu 18.04, a non-root user with sudo privileges, and SSH enabled. You can comply with this guide to initialize your server and complete these steps.

Together with your server initialized, your first step is to install Java; you’ll need it to run  Minecraft . By default, Ubuntu 18.04 does not present a current sufficient model of Java as a way to run the most recent releases of Minecraft. Fortuitously, there are third-occasion maintainers who proceed to build newer Java packages for older Ubuntu releases, and you'll install them by adding their PPA, or Personal Package Archives, to your personal listing of package deal sources. You may do this with the next command:


sudo add-apt-repository ppa:openjdk-r/ppa

Subsequent, replace your package deal sources to reflect this addition:


sudo apt replace

Lastly, set up the OpenJDK model 17 of Java, particularly the headless JRE. This is a minimal version of Java that removes the support for GUI purposes. This makes it excellent for operating Java functions on a server:


sudo apt install openjdk-17-jre-headless

You also want to use a software program called screen 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. That is vital because when you were to begin your server and then close your terminal, this is able to kill the session and cease your server. Set up display screen now:


sudo apt install display screen

Now that you've got the packages installed we have to enable the firewall to allow site visitors to are available to our Minecraft server. Within the preliminary server setup that you just performed you solely allowed ssh site visitors. Now you want to allow for site visitors to are available through port 25565, which is the default port that Minecraft makes use of to permit connections. In some instances ufw will use named site visitors guidelines, comparable to for ssh, which all the time makes use of port 22 by default, however in much less frequent circumstances like this one, we’ll specify the port number manually. Add the required firewall rule by operating the next command:


sudo ufw permit 25565

Now that you've Java put in and your firewall correctly configured, you'll download the Minecraft server app from the Minecraft website.


Step 2 - Downloading the newest Version of Minecraft


Now it's essential obtain the present version of the Minecraft server. You possibly can do this by navigating to Minecraft’s Web site and copying the link that says Download minecraft_server.X.X.X.jar, where 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 will be downloaded as server.jar. For those who ever need to handle versions of Minecraft, or if you want to improve your Minecraft server, it could also be useful to rename the downloaded server.jar to minecraft_server_1.18.1.jar, matching the highlighted version numbers to whatever model you just downloaded:


mv server.jar minecraft_server_1.18.1.jar

1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar nogui


Before analyzing this command’s output, let’s take a better look in any respect 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'll be able to increase this restrict if you'd like your server to begin with extra RAM. Both M for megabytes and G for gigabytes are supported choices. For instance: Xms2G will start the server with 2 gigabytes of RAM.

1. java -Xms1024M -Xmx4G -jar minecraft_server_1.18.1.jar nogui


Give the initialization a few moments.  Quickly your new Minecraft server will start producing an output just like this:
