Raspberry Pi Tutorial: Host A Minecraft Server On Ubuntu Desktop
Welcome to the second in our sequence of Linux gaming posts in the run as much as the holidays. This week, we’ve put collectively a tutorial that teaches you the right way to create a basic Minecraft Server on a Raspberry Pi with Ubuntu Desktop, so you'll be able to play locally with your friends.
This is a superb afternoon undertaking to work on with a buddy or household member!
Hosting a Minecraft server unlocks a tonne of extra control over how you play Minecraft with your folks. Again You may change the sport rules and problem, the behaviour of enemies and decide how players work together.
Setting up a server can be a great strategy to be taught extra about Linux. Linux is all about tinkering and attempting new issues. While it could possibly appear intimidating at first, the instructions you’ll comply with for this challenge will make it easier to strategy extra complex Linux projects sooner or later!
In this tutorial, we’ll be using a Raspberry Pi four 4GB with a 32GB SD card, but you too can follow along on just about any laptop or Laptop that has Ubuntu Desktop put in. You would even use a Digital Machine.
Try these tutorials for getting began with Ubuntu Desktop on these platforms:
Computer tutorial
VirtualBox tutorial
Raspberry Pi tutorial

Be aware: We’ll be utilizing Ubuntu Desktop 21.10 for Raspberry Pi on this tutorial, and advocate you follow together with Ubuntu Desktop 21.10 on no matter device you employ.
Of course, you’ll also need one other Laptop or laptop with Minecraft Java Version put in so you may connect to your server as soon as you’ve created it!
Let’s leap in.
Set up Ubuntu on your Raspberry Pi and replace
If you’ve adopted the Raspberry Pi installation tutorial, you’ll be pretty much able to go, however at any time when we start a brand new undertaking, it’s at all times vital to ensure every thing is updated.
Go forward and open a terminal (ALT+T or click the Terminal icon in your sidebar) and type:
Enter your password and press Y when prompted.
This can examine whether your version of Ubuntu is up to date and download and install any new packages.
Install Java
Minecraft servers are based mostly on Minecraft Java Version, the unique model of Minecraft, so our next step is to put in Java on our Raspberry Pi. The default Java on Ubuntu is older than the one used for Minecraft Servers, so we have to specifically set up the newest Java Runtime Surroundings (jre), which is version 18:
Type your password and press Y when prompted.
Create a folder to your server
Now you want a place to put the Minecraft server on your Pi. We may do it the ‘Windows’ method by opening the file manager, right-clicking, and creating a brand new Folder named Minecraft. But we’re already in the terminal, so let’s keep typing here!
The above will do exactly the same thing as using the file supervisor. In truth, you may check the file supervisor your self to confirm that the brand new folder has appeared!
Since we’re going to put in our server inside the brand new folder, we'd like to inform our terminal that we’re going to work there.
When you sort
You may see that we’re nonetheless in the home listing of our Computer. Again You’ll see your Documents and Downloads folders, as well as the new Minecraft folder you created. To get inside this folder, we'd like to change Directory (cd), so sort:
When you kind ls again, you can see that now nothing is returned, because we’re inside an empty folder. You’ll also see that your prompt now contains the Minecraft folder name:
Download Minecraft Server!
Go away your terminal open, however now you also have to open your internet browser.
In your browser, go to this web page: https://www.minecraft.web/en-us/download/server
We want to download the server linked right here, but as an alternative of left-clicking it, let’s Right-Click on and choose Copy Hyperlink.
This will ensure you all the time get the newest model of the server when following this tutorial!
Leave that web page open, as we’ll come back to it shortly. Now return to the terminal window, making sure we’re still in the Minecraft folder, and inform the terminal to download the server to this folder.
After which Right-Click on and Paste the hyperlink to the server. It should look one thing like this:
Then press ENTER. This command instructs your Pi to ‘get’ (obtain) whatever file is linked at that web handle you gave it.
You will see the obtain full, and in the event you then kind:
You’ll see we now have a server.jar file in our Minecraft folder!
Begin your server!
Return to https://www.minecraft.internet/en-us/obtain/server, and this time copy the Java directions listed into your terminal.
Press ENTER and… Error??
That’s as a result of we just told our Pi to run a file known as minecraft_server.1.18.jar, but you can see from our last ls that when we put in the server it was just referred to as server.jar.
That’s a simple fix.
In the event you press UP on the keyboard, your last instruction will be repeated. Do that now, after which edit the filename to server.jar and press ENTER again.
Form of. Now we've got another error. We need to comply with the tip Person License Settlement (EULA) earlier than we will get began.
So where’s the EULA?
Properly let’s use our trusty
on our Minecraft directory one more time. You’ll see the installation course of has created a set of new information. This is nice, because these recordsdata are what allows us to play around with the game rules! However before we can get to the fun stuff, let’s sign the EULA.
We will do this immediately in the terminal (you are able to do all the things within the terminal, that’s why it’s so cool) using a textual content editor called nano. Kind:
This will open the eula.txt file in your terminal window. Now you simply need to change the eula line to true instead of false.
Then we press CTRL+S to avoid wasting and CTRL+X to exit again to the Command Line.
Let’s try the server once more!
If you press UP just a few times on your keyboard, we will repeat the instruction from earlier with out typing it out once more.
But let’s make one final change before we run things and double the -Xmx1024M and -Xms1024M in our command to -Xmx2048M and -Xms2048. Xmx and Xms refer to the amount of reminiscence the server will use. The more we give it, the higher the performance.
Now we press ENTER once more and the server ought to begin correctly!
This subsequent bit is going to take some time. And you probably won’t be able to browse Facebook whilst you’re ready, as a lot of the Raspberry Pi can be focussed on standing up the server.
As soon as your server has completed setting up, you’ll in all probability get a number of messages like this relying on how much reminiscence you assigned it in the earlier command. It’s regular to have a few of those at startup no matter occurs, so don’t worry an excessive amount of.
Prime Tip: Better hardware means a better server. If you’re considering keeping your server around, or using it with lots of people, an 8GB Raspberry Pi 4 (with elevated Xmx and Xms numbers) will perform higher. Attaching an SSD through a USB3.Zero port will even assist.
Finally, as players join, you’ll be able to see key occasions appear on the terminal as they happen in the sport world.
You can cease your server any time by typing
within the Terminal. This may even save your world so you possibly can resume again at a later time.
Joining the Minecraft server over your local network
If you’ve invited your friends to affix your server on their laptops, they’re in all probability a bit impatient to get going by now. However we’re finally ready!
On your (or your friend’s) laptop or Computer, be sure that you are operating the Java Version of Minecraft (which you'll install from the official Minecraft site - just download it and double-click).
Then they need to navigate to Multiplayer > Direct Connection.
Now they need to enter the native IP tackle of the server which is… hmmm. We don’t know.
Let’s go back to our server terminal!
To search out out the server’s native IP, you should open a second terminal window, or a brand new tab in the present terminal (or just stop your server for this bit and restart it after).
This will produce a string of numbers, however you solely need the primary set.
Looking on the above, my native IP is Yours shall be related but not the same.
So that’s what my guests should add in their video games:
Once your company have entered your server IP, they simply have to click Join Server and they’re in!
Unfortunately for my server, I spawned proper next to a spider. And it was raining.
Modifying your Server Settings
If you want to play common Minecraft domestically with your mates, then you’re all completed - congratulations! However the very best part of operating a server is which you could play god with the sport world!
Let’s close the server (cease, remember?) and do some tweaking.
This time, we want to do the same thing as we did to signal the EULA but this time we’re going to edit a file referred to as server.properties (you might need noticed it the last time we used ls).
This could bring up all the configuration options on your server. For those who scroll down there’s quite a couple of!
I won’t go into element on every option, however you'll be able to read about them on the Minecraft Wiki.
Personally, I simply want to turn off the spiders and change the server’s message of the day, so I’m going to make the following tweaks:
Simply as before, we press CTRL+S and then CTRL+X to avoid wasting and exit!
Top Tip: If you need to start a brand new Minecraft server, simply delete the World folder out of your Minecraft directory, or rename the level-identify in server.properties. This can create a brand new gameworld folder with the updated title subsequent time the server begins, and you'll change again to the outdated one any time!
Connecting to your Minecraft server remotely
In this venture, we’ve shown you how to arrange and customise a Minecraft server in your Raspberry Pi 4, and the way players on the identical Wi-Fi network can join locally to your gameworld.
You’ve additionally realized some helpful Linux commands, like ls, nano, and mkdir!
However what if your friends want to connect remotely, from their own homes?
When we expect about players connecting over the internet, we have to discuss extra superior concepts like port forwarding. We additionally want to contemplate safety and what internet strangers might do if they gained access to your Raspberry Pi.
