How To Set Up A Minecraft Server On Debian 10 - Techlear

Minecraft is a popular game. There are many versions of Minecraft, but all share the same need for a server to host and keep track of all players. In this tutorial we will show you how to set up your own Minecraft server on Debian 10, using open-source tools available from their official website.



PrerequisiteDebian installation with root privileges is required.



- A Minecraft server that is compatible with the version of your Debian release. If you're using Ubuntu, you can check their website to see which one works for you. If it's not clear which one to use, try googling Minecraft Server compatible on Debian /Ubuntu or ask in the comments and we'll help!



Update your Debian system to the latest release.



This is a good idea before installing any additional packages because it will provide you with all of the latest updates and security patches for both Debian software as well as installed applications like Minecraft server. You can do this by running the following commands in a terminal:



These commands are executed in tandem, updating first and then upgrading after it has been completed successfully. These commands should be executed in tandem. If there are no pending updates, they should take less than five minutes. Larger upgrades can take longer so be patient!



Java can be installed



This will download and install the latest Java version. If you have multiple versions installed, this will remove them all for simplicity's sake! Once completed, you can confirm which version is currently running by typing the command below in your terminal:



That's it! Java has been installed on your server.



Create a new Minecraft user



In this example we create a new user called'minecraft'



Once you have completed that step, type in or copy-paste the password for this account twice more to confirm it. This is important because each account should have a unique password.



Take a look at this sample output



Add the new user to the sudo group.



Install Screen



Screen is a GNU utility that allows you to multiplex terminal sessions. This is a useful tool for remote access, allowing you to detach from an ssh session and resume it later without the need of closing that instance (which would disconnect you).



To install Screen, type the following:



This command will install screen, along with all its dependencies, to your server.



This is the end of this task, continue with the next task below.



Install Minecraft



Then, quit your current SSH connection and log back in with the minecraft username that we created earlier.



Create a new folder named minecraft and then move it to your desktop.



Now, download the latest version of Minecraft.net to this directory. Refer to the Minecraft server page to get the latest version of Minecraft Server, replace the version section below with that URL.



Create a startup script



This allows your server start when you reboot your computer or Debian itself. It is also very useful if your home internet connection drops, and you need the server to restart without you having to log into!



Copy and paste the following lines in your terminal



jar parameter can be configured to keep your world persistent or not; if you want a fresh start every time then use nogui. If you don’t have enough RAM to support this setup in Debian (or Ubuntu), drop the -Xmx value of 2560M and change it to something lower, such as 512M.



Save your script using Ctrl–o, exit Nano by Ctrl–x, then confirm that you want this file saved by pressing "y" when prompted. You should now have a Startup script in /home/minecraft/ It will automatically begin on boot. To test it out type or copy-paste the following command:



If you do not recognize errors such "java", please double-check your java installation process.



Start.sh executable



After you're done, close the terminal window and type "exit" to exit. To disconnect from this ssh connection completely, you can simply type exit or hit Ctrl-D at a prompt. You can also use nano again and remove ./start.sh. If you have already done so in a previous instance (e.g., for Minecraft Server), then it won't prompt again. let's talk about games These agreements allow Debian's repositories download packages from another server for yours. This can be more convenient, as they are often more up-to-date than yours. Once accepted, the installation should take just a few minutes to complete and no further action is necessary until that process has finished downloading all needed files and resources.



The next step is to open the eula.txt file and set eula=true. This will allow your server connect to the Minecraft client software. Open that file in your preferred editor and ensure it reads: eula=true.



The next step is using screen to run our Minecraft server process independently so that we don't need to be logged into the minecraft user account at all times when administering the game server remotely via SSH.



This will create a new "session" called minecraft running the Minecraft process in the background; we can access this from any other shell we are logged into.



Configure Your Minecraft Server Firewall



Next is to set up your firewall. Debian's built-in firewall, ufw, allows us to have great control over which programs can access external network resources like the internet. It also includes port forwardeding, which allows certain ports through based on criteria such as source IPs or destination address.



Debian's default settings allow only SSH traffic. Let's go ahead and add rules for Minecraft by typing:



Connect to your Minecraft Server



Open your Minecraft client and select the Multiplayer tab. Enter your server's name, IP address, and password.



Notable: To play on a public network, you will need an external domain name from any domains provider and to set up Dynamic DNS yourself. This is beyond the scope this tutorial.



You can now connect the server. Click on the Join Server link.



Congratulations! Now you can play Minecraft and create worlds. You can build worlds and have fun with your friends, too. The Minecraft Wiki provides more tips and assistance.
