Raspberry Pi Tutorial: Host A Minecraft Server On Ubuntu Desktop
Welcome to the second in our series of Linux gaming posts within the run up to the holidays. This week, we’ve put together a tutorial that teaches you how to create a basic Minecraft Server on a Raspberry Pi with Ubuntu Desktop, so you possibly can play domestically with your pals.
This is a great afternoon challenge to work on with a buddy or household member!
Hosting a Minecraft server unlocks a tonne of further management over the way you play Minecraft with your mates. You can change the sport rules and problem, the behaviour of enemies and decide how gamers work together.
Organising a server can also be an awesome option to learn extra about Linux. Linux is all about tinkering and trying new things. Whereas it may well appear intimidating at first, the instructions you’ll comply with for this challenge will provide help to method extra complicated Linux initiatives in the future!
On this tutorial, we’ll be utilizing a Raspberry Pi 4 4GB with a 32GB SD card, however you can even observe alongside on just about any laptop computer or Computer that has Ubuntu Desktop installed. You could possibly even use a Virtual Machine.
Check out these tutorials for getting began with Ubuntu Desktop on these platforms:
Laptop tutorial
VirtualBox tutorial
Raspberry Pi tutorial

Note: We’ll be utilizing Ubuntu Desktop 21.10 for Raspberry Pi on this tutorial, and suggest you follow together with Ubuntu Desktop 21.10 on no matter device you utilize.
Of course, you’ll additionally need another Laptop or laptop with Minecraft Java Version put in so you possibly can connect to your server once you’ve created it!
Let’s bounce in.
Set up Ubuntu on your Raspberry Pi and update
If you’ve followed the Raspberry Pi installation tutorial, you’ll be pretty much able to go, but at any time when we start a new venture, it’s all the time necessary to verify the whole lot is up to date.
Go forward and open a terminal (ALT+T or click on the Terminal icon in your sidebar) and kind:
Enter your password and press Y when prompted.
This may verify whether your version of Ubuntu is updated and download and set up any new packages.
Set up Java
Minecraft servers are based mostly on Minecraft Java Edition, the unique version 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 latest Java Runtime Setting (jre), which is version 18:
Sort your password and press Y when prompted.
Create a folder for your server
Now you want a place to place the Minecraft server in your Pi. We may do it the ‘Windows’ manner 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 right here!
The above will do exactly the identical factor as using the file manager. In reality, you may verify the file supervisor your self to verify that the brand new folder has appeared!
Since we’re going to install our server inside the brand new folder, we'd like to inform our terminal that we’re going to work there.
Should you type
You'll be able to see that we’re nonetheless in the house listing of our Computer. You’ll see your Paperwork and Downloads folders, in addition to the new Minecraft folder you created. To get inside this folder, we'd like to vary Listing (cd), so kind:
Should you type ls again, you may see that now nothing is returned, because we’re inside an empty folder. You’ll also see that your prompt now includes the Minecraft folder identify:
Download Minecraft Server!
Depart your terminal open, however now you additionally have to open your internet browser.
In your browser, go to this web page: https://www.minecraft.net/en-us/obtain/server
We need to obtain the server linked here, however as an alternative of left-clicking it, let’s Right-Click on and select Copy Link.
This may ensure you always get the newest model of the server when following this tutorial!
Go away that page open, as we’ll come back to it shortly. Now return to the terminal window, making sure we’re nonetheless in the Minecraft folder, and tell the terminal to obtain the server to this folder.
And then Right-Click on and Paste the hyperlink to the server. It ought to look one thing like this:
Then press ENTER. This command instructs your Pi to ‘get’ (download) no matter file is linked at that internet handle you gave it.
You will note the download complete, and in the event you then type:
You’ll see we now have a server.jar file in our Minecraft folder!
Start your server!
Return to https://www.minecraft.net/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 informed our Pi to run a file called minecraft_server.1.18.jar, however you possibly can see from our final ls that after we installed the server it was simply called server.jar.
That’s a simple repair.
In the event you press UP on the keyboard, your last instruction can be repeated. Do that now, and then edit the filename to server.jar and press ENTER once more.
Success!
Type of. Now we've another error. We have to agree to the top Person License Settlement (EULA) before we are able to get started.
So where’s the EULA?
Well let’s use our trusty
on our Minecraft directory one more time. You’ll see the set up process has created a set of new recordsdata. This is good, as a result of these files are what allows us to play around with the game rules! However earlier than we can get to the fun stuff, let’s signal the EULA.
We are able to do this directly in the terminal (you are able to do all the pieces in the terminal, that’s why it’s so cool) utilizing a textual content editor called nano. Kind:
This may open the eula.txt file in your terminal window. Now you simply need to vary the eula line to true instead of false.
Then we press CTRL+S to save and CTRL+X to exit again to the Command Line.
Let’s try the server once more!
When you press UP just a few occasions in your keyboard, we are able to repeat the instruction from earlier without typing it out once more.
But let’s make one last change before we run issues and double the -Xmx1024M and -Xms1024M in our command to -Xmx2048M and -Xms2048. Xmx and Xms consult with the amount of reminiscence the server will use. The extra we give it, the higher the performance.
Now we press ENTER again and the server should begin correctly!
This next bit goes to take some time. And also you probably won’t be able to browse Fb whilst you’re ready, as many of the Raspberry Pi can be focussed on standing up the server.
As soon as your server has finished establishing, you’ll probably get a few messages like this depending on how a lot reminiscence you assigned it within the earlier command. It’s normal to have a couple of of these at startup no matter happens, so don’t fear too much.
Prime Tip: Better hardware means a better server. If you’re contemplating maintaining your server around, or utilizing it with lots of people, an 8GB Raspberry Pi 4 (with increased Xmx and Xms numbers) will perform better. Attaching an SSD by way of a USB3.Zero port will even help.
Finally, as gamers join, you’ll be capable of see key events seem on the terminal as they happen in the game world.
Ouch.
You possibly can stop your server any time by typing
within the Terminal. This can even save your world so you possibly can resume again at a later time.
Becoming a member of the Minecraft server over your native community
If you’ve invited your friends to join your server on their laptops, they’re probably a bit impatient to get going by now. However we’re lastly prepared!
In your (or your friend’s) laptop or Pc, ensure that you might be working the Java Version of Minecraft (which you'll set up from the official Minecraft site - just download it and double-click on).
Then they should 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 local IP, it's good to open a second terminal window, or a new tab in the present terminal (or simply cease your server for this bit and restart it after).
This will produce a string of numbers, however you solely want the first set.
Looking at the above, my local IP is 192.168.1.222. Yours can be comparable but not the same.
So that’s what my guests ought to add in their video games:
Once your guests have entered your server IP, they only have to click Be a part of Server and they’re in!
Sadly for my server, I spawned right subsequent to a spider. And it was raining.
Modifying your Server Settings
If you wish to play common Minecraft locally with your mates, then you’re all finished - congratulations! However the best a part of working a server is you can play god with the game world!
Let’s close the server (cease, remember?) and do some tweaking.
This time, we need to do the same thing as we did to signal the EULA however this time we’re going to edit a file called server.properties (you might need noticed it the final time we used ls).
Type:
This should carry up all the configuration choices for your server. If you scroll down there’s fairly just a few!
I won’t go into element on each possibility, but you'll be able to read about them on the Minecraft Wiki.
Personally, I just want to turn off the spiders and change the server’s message of the day, so I’m going to make the next tweaks:
Simply as earlier than, we press CTRL+S after which CTRL+X to save lots of and exit!
High Tip: If you want to begin a new Minecraft server, simply delete the World folder from your Minecraft listing, or rename the level-identify in server.properties. This will create a new gameworld folder with the up to date title next time the server starts, and you may swap again to the outdated one any time!
Connecting to your Minecraft server remotely
On this challenge, we’ve proven you the best way to set up and customise a Minecraft server on your Raspberry Pi 4, and the way players on the same Wi-Fi network can connect domestically to your gameworld.
You’ve additionally realized some handy Linux commands, like ls, nano, and mkdir!
However what if your mates need to connect remotely, from their very own homes? premium content
When we expect about gamers connecting over the web, we have to talk about more advanced ideas like port forwarding. We additionally need to consider security and what internet strangers may do in the event that they gained entry to your Raspberry Pi.
