sudo apt updateLastly, 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 ideally suited for running Java functions on a server:



sudo apt set up openjdk-17-jre-headlessYou also need to make use of a software program known as display screen to create detachable server periods. display permits you to create a terminal session and detach from it, leaving the method began on it operating. This is essential as a result of if you were to begin your server and then shut your terminal, this might kill the session and stop your server. Set up display screen now:



sudo apt install screenNow that you've the packages put in we need to enable the firewall to allow visitors to are available to our Minecraft server. In the preliminary server setup that you just carried out you solely allowed ssh site visitors. Now you need to allow for site visitors to are available in by way of port 25565, which is the default port that Minecraft makes use of to permit connections. In some circumstances ufw will use named site visitors guidelines, reminiscent of for ssh, which always makes use of port 22 by default, but in less widespread cases like this one, we’ll specify the port quantity manually. Add the mandatory firewall rule by running the following command:

Step 2 - Downloading the most recent Version of Minecraft



Now you want to obtain the current version of the Minecraft server. You can do that by navigating to Minecraft’s Web site and copying the hyperlink that claims Download minecraft_server.X.X.X.jar, where the X’s are the latest version of the server.



Now you can 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 can be downloaded as server.jar.

1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar noguiEarlier than examining 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 start out operating with 1024MB or 1GB of RAM running. You possibly can elevate this limit if you need your server to start 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.
