With your server initialized, your first step is to put in Java; you’ll need it to run Minecraft. By default, Ubuntu 18.04 doesn't provide a latest sufficient model of Java with a purpose to run the latest releases of Minecraft. Fortuitously, there are third-occasion maintainers who continue to build newer Java packages for older Ubuntu releases, and you'll install them by adding their PPA, or Personal Package deal Archives, to your own list of bundle sources.

sudo add-apt-repository ppa:openjdk-r/ppa
Next, replace your package sources to mirror this addition:
sudo apt update
Finally, install the OpenJDK version 17 of Java, particularly the headless JRE. It is a minimal model of Java that removes the support for GUI functions. This makes it ideal for operating Java applications on a server:
sudo apt install openjdk-17-jre-headless
You additionally need to make use of a software program referred to as screen to create detachable server classes. screen allows you to create a terminal session and detach from it, leaving the method began on it running. That is important because if you had been to start out your server after which close your terminal, this could kill the session and stop 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 permit visitors to are available in to our Minecraft server. Within the initial server setup that you carried out you solely allowed ssh traffic. Now you need to permit for traffic to come in through port 25565, which is the default port that Minecraft makes use of to permit connections. In some circumstances ufw will use named traffic rules, corresponding to for ssh, which at all times uses port 22 by default, however in less frequent cases like this one, we’ll specify the port number manually. Add the mandatory firewall rule by working the next command:
sudo ufw permit 25565
Now that you've Java installed and your firewall correctly configured, you'll download the Minecraft server app from the Minecraft webpage.
Step 2 - Downloading the newest Model of Minecraft
Now you want to obtain the current model of the Minecraft server. You may do this by navigating to Minecraft’s Webpage and copying the link that claims Download minecraft_server.X.X.X.jar, where the X’s are the most recent model of the 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.jar
The server app can be downloaded as server.jar. In the event you 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 model numbers to no matter version you simply downloaded:
mv server.jar minecraft_server_1.18.1.jar
If you want to obtain an older model of Minecraft, you'll find them archived at mcversions.web. However this tutorial will focus on the present latest release. Now that you've your obtain, let’s start configuring your Minecraft server.

Now you can carry out your initial configuration. Don't be alarmed when the next 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 this subsequent:
1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar nogui
Before examining this command’s output, let’s take a better look in any respect these command-line arguments, which are tuning your server:
- Xms1024M - This configures the server to start operating with 1024MB or 1GB of RAM operating. You possibly can elevate this restrict in order for you 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.
- Xmx1024M - This configures the server to use, at most, 1024M of RAM. You possibly can increase this limit in order for you your server to run at a bigger measurement, allow for extra players, or if you're feeling that your server is working slowly. Java programs are distinctive in that they all the time require you to specify the maximum quantity of reminiscence they can 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 primary time you run this command, which normally begins your server, you will receive this output:
These errors had been generated because the server could not discover two vital information required for execution: the EULA (Finish Person License Settlement), found in eula.txt, and the configuration file server.properties. For the reason that server was unable to find these files, it created them in your present working directory. Minecraft does this intentionally to make sure that you have learn and consented to its EULA.

Once you have set the choices that you want, save and shut the file.
Now you'll be able to 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 necessary. Remember, you might be welcome to adjust this number to fit your server limitations or person needs:
1. java -Xms1024M -Xmx4G -jar minecraft_server_1.18.1.jar nogui
Give the initialization a few moments. Soon your new Minecraft server will begin producing an output just like this:
