Conditions

With a view to comply with this information, you’ll need:

- A server with a contemporary installation of Ubuntu 18.04, a non-root consumer with sudo privileges, and SSH enabled.

- A replica of Minecraft Java Version installed on a local Mac, Home windows, or Linux machine.

Step 1 - Installing the necessary Software program Packages and Configure the Firewall

With your server initialized, your first step is to install Java; you’ll want it to run Minecraft. By default, Ubuntu 18.04 doesn't provide a latest sufficient version of Java with a view to run the newest releases of Minecraft. Happily, there are third-social gathering maintainers who continue to construct newer Java packages for older Ubuntu releases, and you can install them by adding their PPA, or Private Bundle Archives, to your individual listing of package deal sources. You'll be able to do this with the following command:

sudo add-apt-repository ppa:openjdk-r/ppaSubsequent, update your package deal sources to reflect this addition:

sudo apt updateFinally, install the OpenJDK model 17 of Java, particularly the headless JRE. This is a minimal version of Java that removes the assist for GUI purposes. This makes it excellent for working Java functions on a server:

sudo apt install openjdk-17-jre-headlessYou also need to make use of a software referred to as display screen to create detachable server sessions. screen lets you create a terminal session and detach from it, leaving the process began on it working. This is vital because in case you were to start out your server and then shut your terminal, this would kill the session and stop your server. Install display screen now:

sudo apt install display screenNow that you have the packages installed we need to enable the firewall to allow traffic to come in to our Minecraft server. In the preliminary server setup that you carried out you solely allowed ssh traffic. Now you need to permit 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 circumstances ufw will use named site visitors guidelines, such as for ssh, which always uses port 22 by default, but in much less widespread circumstances like this one, we’ll specify the port quantity manually. Add the mandatory firewall rule by working the next command:

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

Step 2 - Downloading the most recent Version of Minecraft

Now it is advisable to download the current version of the Minecraft server. You may do that by navigating to Minecraft’s Website and copying the link that claims 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 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. In case you ever need to handle versions of Minecraft, or if you wish to improve 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 whatever version you just downloaded:

mv server.jar minecraft_server_1.18.1.jarIf you wish to obtain an older version of Minecraft, you'll find them archived at mcversions.net. But this tutorial will deal with the current latest release. Now that you've got your obtain, let’s begin configuring your Minecraft server.

You can now perform your preliminary configuration. Do not be alarmed when the subsequent command throws an error. Minecraft has designed its set up this manner so that customers must first consent to the company’s licensing agreement. You'll do this next:

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

- Xms1024M - This configures the server to begin working with 1024MB or 1GB of RAM running. You can elevate this restrict if you'd like your server to start out with extra RAM. Both M for megabytes and G for gigabytes are supported options. For example: Xms2G will start the server with 2 gigabytes of RAM.

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

As soon as the server is up and working, you will see the next output:
