Raspberry Pi Tutorial: Host A Minecraft Server On Ubuntu Desktop
Welcome to the second in our collection of Linux gaming posts within the run up to the holidays. This week, we’ve put collectively a tutorial that teaches you the right way to create a fundamental Minecraft Server on a Raspberry Pi with Ubuntu Desktop, so you may play locally with your mates.

This is a great afternoon mission to work on with a good friend or household member!

Hosting a Minecraft server unlocks a tonne of extra management over how you play Minecraft with your mates. You possibly can change the sport rules and difficulty, the behaviour of enemies and determine how gamers work together.

Establishing a server is also a fantastic strategy to learn more about Linux. Linux is all about tinkering and making an attempt new issues. Whereas it might seem intimidating at first, the instructions you’ll comply with for this mission will aid you approach extra complex Linux tasks in the future!

In this tutorial, we’ll be utilizing a Raspberry Pi 4 4GB with a 32GB SD card, however you may also observe along on pretty much any laptop computer or Laptop that has Ubuntu Desktop put in. You may even use a Digital Machine.

Take a look at these tutorials for getting began with Ubuntu Desktop on these platforms:

Computer tutorial

VirtualBox tutorial

Raspberry Pi tutorial


Be aware: We’ll be using Ubuntu Desktop 21.10 for Raspberry Pi in this tutorial, and advocate you observe along with Ubuntu Desktop 21.10 on whatever gadget you use.

In fact, you’ll additionally need one other Pc or laptop computer with Minecraft Java Edition put in so you possibly can connect to your server once you’ve created it!

Let’s bounce in.

Set up Ubuntu in your Raspberry Pi and replace

If you’ve adopted the Raspberry Pi installation tutorial, you’ll be pretty much ready to go, but every time we start a brand new venture, it’s always essential to verify all the things is up to date.

Go ahead and open a terminal (ALT+T or click on the Terminal icon in your sidebar) and type:

Enter your password and press Y when prompted.

It will check whether your model 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 original version of Minecraft, so our next step is to install Java on our Raspberry Pi. The default Java on Ubuntu is older than the one used for Minecraft Servers, so we need to particularly set up the newest Java Runtime Atmosphere (jre), which is model 18:

Kind your password and press Y when prompted.

Create a folder on your server

Now you want a place to place the Minecraft server in your Pi. We could do it the ‘Windows’ manner by opening the file supervisor, right-clicking, and creating a brand new Folder named Minecraft. However we’re already within the terminal, so let’s keep typing here!

The above will do precisely the same thing as using the file supervisor. In actual fact, you possibly can verify the file manager your self to confirm that the new folder has appeared!

Since we’re going to put in our server inside the brand new folder, we'd like to tell our terminal that we’re going to work there.

If you sort

You possibly can see that we’re nonetheless in the house directory of our Computer. You’ll see your Paperwork and Downloads folders, as well as the brand new Minecraft folder you created. To get inside this folder, we need to change Listing (cd), so kind:

In the event you sort ls once more, you possibly can see that now nothing is returned, as a result of we’re inside an empty folder. You’ll additionally see that your immediate now includes the Minecraft folder title:

Download Minecraft Server!

Leave your terminal open, however now you also have to open your internet browser.

In your browser, go to this page: https://www.minecraft.internet/en-us/obtain/server

We need to obtain the server linked here, however as an alternative of left-clicking it, let’s Proper-Click and select Copy Link.

It will make sure you always get the most recent version of the server when following this tutorial!

Depart that page open, as we’ll come back to it shortly. Now go back to the terminal window, making sure we’re nonetheless within the Minecraft folder, and tell the terminal to obtain the server to this folder.

After which Proper-Click on and Paste the hyperlink to the server. It ought to look something like this:

Then press ENTER. This command instructs your Pi to ‘get’ (download) no matter file is linked at that net tackle you gave it.

You will see the download full, and if you then sort:

You’ll see we now have a server.jar file in our Minecraft folder!

Start your server!

Go back to https://www.minecraft.web/en-us/download/server, and this time copy the Java instructions listed into your terminal.

Press ENTER and… Error??

That’s because we just instructed our Pi to run a file called minecraft_server.1.18.jar, but you'll be able to see from our last ls that once we installed the server it was just called server.jar.

That’s an easy repair.

When you press UP on the keyboard, your last instruction will likely be repeated. Do that now, after which edit the filename to server.jar and press ENTER again.

Success!

Kind of. Now we've one other error. We have to agree to the top User License Settlement (EULA) earlier than we can get began.

So where’s the EULA?

Nicely let’s use our trusty

on our Minecraft directory one more time. You’ll see the installation process has created a set of latest files. This is good, because these files are what permits us to play round with the sport guidelines! But earlier than we are able to get to the enjoyable stuff, let’s sign the EULA.

We are able to do that straight within the terminal (you are able to do all the pieces within the terminal, that’s why it’s so cool) using a text editor known as nano. Kind:

This will open the eula.txt file in your terminal window. Now you simply need to alter the eula line to true as a substitute of false.

Then we press CTRL+S to save and CTRL+X to exit again to the Command Line.

Let’s attempt the server once more!

In the event you press UP a number of instances on your keyboard, we are able to repeat the instruction from earlier with out typing it out again.

However let’s make one final change earlier than 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 ought to start correctly!

This subsequent bit is going to take some time. And also you in all probability won’t have the ability to browse Fb while you’re waiting, as many of the Raspberry Pi can be focussed on standing up the server.

As soon as your server has finished setting up, you’ll most likely get a number of messages like this relying on how much memory you assigned it within the previous command. motorsnmore to have just a few of those at startup no matter occurs, so don’t fear too much.

Prime Tip: Higher hardware means a better server. If you’re considering holding your server around, or utilizing it with lots of people, an 8GB Raspberry Pi 4 (with increased Xmx and Xms numbers) will perform higher. Attaching an SSD by way of a USB3.Zero port may also assist.

Finally, as players join, you’ll have the ability to see key events seem on the terminal as they happen in the game world.

Ouch.

You'll be able to stop your server any time by typing

within the Terminal. This may also save your world so you may resume again at a later time.

Joining the Minecraft server over your local network

If you’ve invited your friends to hitch your server on their laptops, they’re probably a bit impatient to get going by now. However we’re lastly ready!

On your (or your friend’s) laptop or Laptop, make sure that you are operating the Java Edition of Minecraft (which you'll be able to set up from the official Minecraft site - simply obtain it and double-click on).

Then they need to navigate to Multiplayer > Direct Connection.

Now they should enter the local IP handle of the server which is… hmmm. We don’t know.

Let’s return to our server terminal!

To search out out the server’s native IP, that you must open a second terminal window, or a new tab in the current terminal (or just cease your server for this bit and restart it after).

This may produce a string of numbers, but you only want the primary set.

Wanting on the above, my native IP is 192.168.1.222. Yours might be similar however not the same.

So that’s what my guests ought to add in their games:

Once your visitors have entered your server IP, they just must click on Be a part of Server and they’re in!

Unfortunately for my server, I spawned proper subsequent to a spider. And it was raining.

Modifying your Server Settings

If you want to play common Minecraft locally with your friends, then you’re all accomplished - congratulations! However one of the best part of working a server is which you can play god with the sport world!

Let’s shut the server (stop, remember?) and do some tweaking.

This time, we wish to do the same factor as we did to sign the EULA however this time we’re going to edit a file referred to as server.properties (you may need noticed it the last time we used ls).

Type:

This should convey up all of the configuration choices to your server. If you happen to scroll down there’s quite just a few!

I won’t go into detail on every option, but you'll be able to read about them on the Minecraft Wiki.

Personally, I simply want to turn off the spiders and alter the server’s message of the day, so I’m going to make the next tweaks:

Just as earlier than, we press CTRL+S and then CTRL+X to save lots of and exit!

Top Tip: If you need to start out a brand new Minecraft server, simply delete the World folder from your Minecraft directory, or rename the extent-identify in server.properties. This will create a new gameworld folder with the up to date name subsequent time the server begins, and you can switch back to the previous one any time!

Connecting to your Minecraft server remotely

In this undertaking, we’ve proven you how to arrange and customise a Minecraft server in your Raspberry Pi 4, and the way gamers on the same Wi-Fi community can connect locally to your gameworld.

You’ve additionally discovered some useful Linux commands, like ls, nano, and mkdir!

But what if your pals need to connect remotely, from their very own homes?

When we expect about players connecting over the internet, we have to speak about more superior ideas like port forwarding. We additionally need to think about safety and what internet strangers may do if they gained access to your Raspberry Pi.
