Raspberry Pi Tutorial: Host A Minecraft Server On Ubuntu Desktop
Welcome to the second in our collection of Linux gaming posts within the run as much as the vacations. This week, we’ve put together a tutorial that teaches you methods to create a fundamental Minecraft Server on a Raspberry Pi with Ubuntu Desktop, so you may play locally with your friends.

This is a good afternoon venture to work on with a friend or family member!

Hosting a Minecraft server unlocks a tonne of further management over how you play Minecraft with your folks. You'll be able to change the sport guidelines and difficulty, the behaviour of enemies and decide how players interact.

Setting up a server is also a fantastic technique to study extra 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 challenge will aid you method extra advanced Linux tasks in the future!

In this tutorial, we’ll be using a Raspberry Pi four 4GB with a 32GB SD card, but it's also possible to follow along on pretty much any laptop or Computer that has Ubuntu Desktop put in. You can even use a Virtual Machine.

Take a look at 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 on this tutorial, and advocate you observe along with Ubuntu Desktop 21.10 on no matter machine you utilize.

Of course, you’ll also want another Pc or laptop with Minecraft Java Version put in so you'll be able to connect with your server as soon as you’ve created it!

Let’s bounce in.

Install Ubuntu in your Raspberry Pi and replace

If you’ve followed the Raspberry Pi set up tutorial, you’ll be pretty much able to go, but at any time when we start a brand new challenge, it’s always essential to verify the whole lot is updated.

Go forward 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 verify whether your model of Ubuntu is up to date and obtain and set up any new packages.

Install Java

Minecraft servers are based mostly on Minecraft Java Version, the original version of Minecraft, so our subsequent 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 specifically set up the most recent Java Runtime Setting (jre), which is model 18:

Type 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 may do it the ‘Windows’ method by opening the file manager, proper-clicking, and creating a new Folder named Minecraft. But we’re already in the terminal, so let’s keep typing right here!

The above will do precisely the identical thing as utilizing the file supervisor. In actual fact, you can check the file manager yourself to affirm that the brand new folder has appeared!

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

If you sort

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 new Minecraft folder you created. To get inside this folder, we'd like to alter Directory (cd), so sort:

If you sort ls again, you can see that now nothing is returned, because we’re inside an empty folder. You’ll additionally see that your immediate now includes the Minecraft folder name:

Download Minecraft Server!

Go away your terminal open, however now you also must open your net browser.

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

We need to download the server linked right here, but as an alternative of left-clicking it, let’s Right-Click on and select Copy Hyperlink.

It will be sure you at all times get the newest model of the server when following this tutorial!

Go away that page open, as we’ll come back to it shortly. It's uooka time Now return to the terminal window, ensuring we’re still within the Minecraft folder, and inform the terminal to obtain the server to this folder.

And then Proper-Click and Paste the link to the server. It should look one thing like this:

Then press ENTER. This command instructs your Pi to ‘get’ (download) whatever file is linked at that net tackle you gave it.

You will note the obtain complete, and should 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.net/en-us/download/server, and this time copy the Java directions listed into your terminal.

Press ENTER and… Error??

That’s as a result of we simply instructed our Pi to run a file known as minecraft_server.1.18.jar, but you may see from our last ls that after we installed the server it was simply known as server.jar.

That’s an easy repair.

If you happen to press UP on the keyboard, your final instruction will be repeated. Do this now, after which edit the filename to server.jar and press ENTER once more.

Success!

Kind of. Now we've got one other error. We have to comply with the tip Consumer 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 yet one more time. You’ll see the installation process has created a set of new files. This is good, as a result of these recordsdata are what allows us to play round with the game rules! However before we are able to get to the fun stuff, let’s signal the EULA.

We can do this directly in the terminal (you can do every thing in the terminal, that’s why it’s so cool) using a textual content editor referred to as nano. Type:

This can open the eula.txt file in your terminal window. Now you simply need to alter 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 attempt the server again!

In case you press UP a few occasions in your keyboard, we will repeat the instruction from earlier without typing it out again.

However let’s make one last change earlier than we run things and double the -Xmx1024M and -Xms1024M in our command to -Xmx2048M and -Xms2048. Xmx and Xms check with the amount of memory the server will use. The more 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 you probably won’t be capable to browse Fb while you’re waiting, as a lot of the Raspberry Pi will be focussed on standing up the server.

As soon as your server has completed setting up, you’ll probably get a number of messages like this relying on how a lot reminiscence you assigned it in the previous command. It’s normal to have just a few of those at startup whatever occurs, so don’t worry a lot.

High Tip: Better hardware means a greater server. If you’re considering keeping your server around, or using it with a lot of people, an 8GB Raspberry Pi 4 (with increased Xmx and Xms numbers) will perform better. Attaching an SSD by way of a USB3.0 port will also help.

Eventually, as gamers join, you’ll have the ability to see key occasions seem on the terminal as they happen in the sport world.

Ouch.

You can cease your server any time by typing

in the Terminal. This will also 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 mates to affix your server on their laptops, they’re in all probability a bit impatient to get going by now. However we’re lastly ready!

On your (or your friend’s) laptop computer or Computer, be sure you're operating the Java Version of Minecraft (which you'll install from the official Minecraft site - simply download it and double-click).

Then they need to navigate to Multiplayer > Direct Connection.

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

Let’s go back to our server terminal!

To find out the server’s native IP, you need to open a second terminal window, or a brand new tab in the current terminal (or simply cease your server for this bit and restart it after).

This will produce a string of numbers, but you only want the first set.

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

So that’s what my visitors should add in their games:

As soon as your visitors have entered your server IP, they just must click Be part of 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 regionally with your mates, then you’re all completed - congratulations! But the most effective a part of operating a server is that you may play god with the game 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 however 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).

Sort:

This could bring up all the configuration choices to your server. If you happen to scroll down there’s fairly a few!

I won’t go into element on every option, but you can 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 following tweaks:

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

Prime Tip: If you need to begin a new Minecraft server, simply delete the World folder out of your Minecraft directory, or rename the level-identify in server.properties. This may create a new gameworld folder with the up to date name next time the server starts, and you can swap back to the old one any time!

Connecting to your Minecraft server remotely

On this project, we’ve shown 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 join domestically to your gameworld.

You’ve also learned some handy Linux commands, like ls, nano, and mkdir!

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

When we expect about gamers connecting over the internet, we need to talk about more advanced concepts like port forwarding. We additionally need to consider security and what web strangers could do in the event that they gained access to your Raspberry Pi.
