sudo apt updateFinally, install the OpenJDK model 17 of Java, specifically the headless JRE. This can be a minimal model of Java that removes the help for GUI functions. This makes it supreme for operating Java purposes on a server:



sudo apt set up openjdk-17-jre-headlessYou additionally need to use a software program known as display to create detachable server sessions. display permits you to create a terminal session and detach from it, leaving the process started on it working. This is essential because if you happen to were to start out your server after which shut your terminal, this could kill the session and cease your server. Set up display screen now:



sudo apt install display screenNow that you've got the packages installed we have to enable the firewall to allow visitors to are available in to our Minecraft server. Within the initial server setup that you simply performed you solely allowed ssh visitors. Now you need to allow for traffic to are available by way of port 25565, which is the default port that Minecraft makes use of to allow connections. In some cases ufw will use named site visitors rules, corresponding to for ssh, which at all times makes use of port 22 by default, but in less widespread instances like this one, we’ll specify the port number manually. Add the necessary firewall rule by operating the following command:



sudo ufw enable 25565Now that you've got Java installed and your firewall correctly configured, you will download the Minecraft server app from the Minecraft website.



Step 2 - Downloading the most recent Version of Minecraft



Now you might want to download the current version of the Minecraft server. You may do that by navigating to Minecraft’s Webpage and copying the hyperlink that says Download minecraft_server.X.X.X.jar, where the X’s are the most recent version 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.jarThe server app can be downloaded as server.jar.

1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar noguiEarlier than inspecting this command’s output, let’s take a closer look at all these command-line arguments, which are tuning your server:



- Xms1024M - This configures the server to start out operating with 1024MB or 1GB of RAM working. You possibly can raise this restrict if you need your server to start out with more RAM.
