sudo apt updateLastly, set up the OpenJDK version 17 of Java, particularly the headless JRE. This can be a minimal model of Java that removes the help for GUI functions. This makes it ultimate for operating Java functions on a server:

sudo apt install openjdk-17-jre-headlessYou also need to make use of 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 working. This is important as a result of if you happen to were to begin your server and then shut your terminal, this might kill the session and cease your server. Install display screen now:

sudo apt install displayNow that you've got the packages installed we need to enable the firewall to allow traffic to come in to our Minecraft server. Within the preliminary server setup that you simply carried out you only allowed ssh site visitors. Now you want to allow for traffic to are available via port 25565, which is the default port that Minecraft uses to allow connections. In some instances ufw will use named traffic rules, similar to for ssh, which always uses port 22 by default, however in less common cases like this one, we’ll specify the port quantity manually. Add the necessary firewall rule by operating the next command:

sudo ufw allow 25565Now that you've Java put in and your firewall correctly configured, you'll obtain the Minecraft server app from the Minecraft webpage.

Step 2 - Downloading the newest Model of Minecraft

Now it's essential to download the present model of the Minecraft server. You possibly can do this by navigating to Minecraft’s Webpage and copying the link that claims Download minecraft_server.X.X.X.jar, the place the X’s are the newest model of the server. minecraft 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.jarThe server app shall be downloaded as server.jar. When you ever must handle versions of Minecraft, or if you wish 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 version numbers to whatever model you just downloaded:

Now you can perform your initial configuration. Don't be alarmed when the subsequent command throws an error. Minecraft has designed its set up this fashion so that customers must first consent to the company’s licensing settlement. You'll do that subsequent:

1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar noguiBefore 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 begin operating with 1024MB or 1GB of RAM operating. You may elevate this restrict if you need your server to begin with more RAM. Both M for megabytes and G for gigabytes are supported options. For instance: Xms2G will start the server with 2 gigabytes of RAM.

1. java -Xms1024M -Xmx4G -jar minecraft_server_1.18.1.jar noguiGive the initialization a number of moments. Soon your new Minecraft server will begin producing an output much like this:

Once the server is up and working, you will see the next output:
