Raspberry Pi Tutorial: Host A Minecraft Server On Ubuntu Desktop
Welcome to the second in our sequence of Linux gaming posts within the run as much as the vacations. This week, we’ve put collectively a tutorial that teaches you methods to create a basic Minecraft Server on a Raspberry Pi with Ubuntu Desktop, so you possibly can play domestically with your mates.

This is a great afternoon venture to work on with a pal or household member!

Internet hosting a Minecraft server unlocks a tonne of further management over the way you play Minecraft with your mates. You may change the game guidelines and issue, the behaviour of enemies and decide how gamers work together.

Establishing a server can be a fantastic technique to learn extra about Linux. Linux is all about tinkering and trying new issues. While it might probably seem intimidating at first, the directions you’ll comply with for this venture will aid you method more complex Linux tasks sooner or later!

In this tutorial, we’ll be using a Raspberry Pi four 4GB with a 32GB SD card, but you can even follow alongside on pretty much any laptop computer or Laptop that has Ubuntu Desktop installed. You could even use a Virtual Machine.

Try these tutorials for getting started with Ubuntu Desktop on these platforms:

Computer tutorial

VirtualBox tutorial

Raspberry Pi tutorial


Note: We’ll be utilizing Ubuntu Desktop 21.10 for Raspberry Pi in this tutorial, and advocate you follow together with Ubuntu Desktop 21.10 on no matter system you use.

After all, you’ll also need one other Pc or laptop computer with Minecraft Java Edition installed so you can hook up with your server once you’ve created it!

Let’s leap in.

Set up Ubuntu on your Raspberry Pi and update

If you’ve followed the Raspberry Pi set up tutorial, you’ll be pretty much ready to go, however whenever we begin a new mission, it’s always necessary to ensure everything is up to date.

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

Enter your password and press Y when prompted.

This may test whether or not your model of Ubuntu is updated and obtain and install any new packages.

Install Java

Minecraft servers are based mostly on Minecraft Java Version, the unique 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 most recent Java Runtime Surroundings (jre), which is model 18:

Sort your password and press Y when prompted.

Create a folder on your server

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

The above will do exactly the identical factor as using the file supervisor. Actually, you'll be able to examine the file manager yourself to verify that the new folder has appeared!

Since we’re going to install our server inside the new folder, we want to tell our terminal that we’re going to work there.

For those who type

You may see that we’re nonetheless in the house listing of our Computer. You’ll see your Documents 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 type:

Should you type 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!

Depart your terminal open, however now you also must open your web browser.

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

We wish to obtain the server linked here, but as an alternative of left-clicking it, let’s Right-Click on and choose Copy Hyperlink.

This can ensure you all the time get the newest model of the server when following this tutorial!

Depart that web page open, as we’ll come again to it shortly. Now go back to the terminal window, making sure we’re still in the Minecraft folder, and inform the terminal to download the server to this folder.

And then Right-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 web handle you gave it.

You will notice the obtain complete, and for those who then type:

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

Begin your server!

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

Press ENTER and… Error??

That’s as a result of we just informed our Pi to run a file referred to as minecraft_server.1.18.jar, however you possibly can see from our final ls that once we installed the server it was simply called server.jar.

That’s a straightforward fix.

When you press UP on the keyboard, your last instruction might be repeated. Try this now, and then edit the filename to server.jar and press ENTER again.

Success!

Form of. Now we've another error. We need to comply with the top Consumer License Settlement (EULA) earlier than we will get started.

So where’s the EULA?

Well let’s use our trusty

on our Minecraft listing yet one more time. You’ll see the set up course of has created a set of recent recordsdata. This is nice, as a result of these information are what permits us to play around with the sport guidelines! But earlier than we will get to the enjoyable stuff, let’s sign the EULA.

We will do this straight within the terminal (you can do all the things within the terminal, that’s why it’s so cool) utilizing a text editor known as nano. Kind:

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

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

Let’s strive the server once more!

If you press UP just a few occasions in your keyboard, we can 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 discuss with the quantity of reminiscence the server will use. The extra we give it, the higher the efficiency.

Now we press ENTER again and the server ought to begin properly!

This next bit is going to take some time. And also you most likely won’t be capable of browse Facebook while you’re waiting, as a lot of the Raspberry Pi will probably be focussed on standing up the server.

Once your server has completed establishing, you’ll in all probability get a number of messages like this relying on how a lot reminiscence you assigned it in the earlier command. It’s normal to have a number of of these at startup whatever occurs, so don’t worry too much.

High Tip: Higher hardware means a greater server. If you’re considering holding your server round, or utilizing it with lots of people, an 8GB Raspberry Pi 4 (with increased Xmx and Xms numbers) will carry out higher. Attaching an SSD through a USB3.Zero port can even assist.

Ultimately, as players join, you’ll be able to see key events appear on the terminal as they occur in the sport world.

Ouch.

You possibly can stop your server any time by typing

within the Terminal. This will even save your world so you possibly can resume once more at a later time.

Becoming a member of the Minecraft server over your native community

If you’ve invited your friends to hitch your server on their laptops, they’re in all probability a bit impatient to get going by now. But we’re finally ready!

In your (or your friend’s) laptop or Computer, ensure you might be working the Java Edition of Minecraft (which you'll be able to set up from the official Minecraft site - simply obtain it and double-click).

Then they need to navigate to Multiplayer > Direct Connection.

Now they need to enter the native IP deal with of the server which is… hmmm. We don’t know.

Let’s go back to our server terminal!

To seek out out the server’s local IP, you want to open a second terminal window, or a new tab in the present terminal (or simply stop your server for this bit and restart it after).

This will produce a string of numbers, however you solely want the primary set.

Wanting on the above, my local IP is 192.168.1.222. Yours shall be comparable but not the identical.

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

Once your company have entered your server IP, they only need to click Be 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 regular Minecraft locally with your mates, then you’re all completed - congratulations! https://minecraft-servers.biz/ However the best a part of running a server is that you could play god with the game world!

Let’s close the server (cease, remember?) and do some tweaking.

This time, we wish to do the identical factor as we did to sign the EULA however this time we’re going to edit a file known as server.properties (you might need spotted it the final time we used ls).

Type:

This could deliver up all of the configuration options in your server. In case you scroll down there’s fairly a couple of!

I won’t go into detail on each choice, but you possibly can read about them on the Minecraft Wiki.

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

Simply as before, we press CTRL+S after which CTRL+X to save and exit!

Top Tip: If you'd like to begin a new Minecraft server, just delete the World folder from your Minecraft listing, or rename the extent-name in server.properties. This can create a brand new gameworld folder with the up to date identify next time the server starts, and you may change again to the previous one any time!

Connecting to your Minecraft server remotely

In this challenge, we’ve proven you methods to set up and customise a Minecraft server in your Raspberry Pi 4, and the way players on the identical Wi-Fi community can join domestically to your gameworld.

You’ve additionally realized some handy Linux commands, like ls, nano, and mkdir!

But what if your folks need to attach remotely, from their own houses?

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 safety and what internet strangers might do in the event that they gained access to your Raspberry Pi.
