Raspberry Pi Minecraft Server Setup Script w/ Startup Service

Minecraft 1.17 - Caves and Cliffs Update
Minecraft 1.17 – Caves and Cliffs Update

Minecraft 1.17 (Caves and Cliffs Update) is here! This script and guide are written to help you get a great performing Raspberry Pi Minecraft server up and running in only a few minutes.

This is the standalone version. It runs on most flavors of Linux and should work on most architectures as well (arm, aarch64, etc.).

I highly recommend using Docker over the standalone version for most people. Installing Docker is as simple as sudo apt install docker.io. There are 3 Docker options available:

It’s now possible to convert your worlds between Bedrock and Java versions. Check out my guide on Chunker here for more information.


  • Sets up fully operational Minecraft server in a couple of minutes
  • Runs the highly efficient “Paper” Minecraft server
  • Raspbian / Ubuntu / Debian distributions supported
  • Installs and configures OpenJDK 18
  • Sets up Minecraft as a system service with option to autostart at boot
  • Automatic backups to minecraft/backups when server restarts
  • Updates automatically to the latest version when server is started
  • Easy control of server with start.sh, stop.sh and restart.sh scripts
  • Optional scheduled daily restart of Pi using cron


  • Raspberry Pi model with 1 GB of RAM or higher. Basically a Raspberry Pi 2B or higher. (No Zero unfortunately, 512MB is not enough RAM to do this, I’ve tried!)
  • Headless Linux distribution such as Raspbian Buster Lite, Ubuntu Server 18.04.2, or any Debian based distribution (GUI distros can be used at the expense of available RAM and server performance)
  • Solid state drive highly recommended but not required.
    You can get a SSD setup on a Pi for less than most Micro SD cards cost. See my article here for details
  • If using MicroSD you want to be using a high range card otherwise you will really be hurting on IO when the server is reading/writing chunks of terrain! Click here for MicroSD card benchmarks/recommendations.

The SanDisk Extreme A1-A2 SD card has the best scoring SD card on Pi Benchmarks for years and is second in popularity only to the SanDisk Ultra (often included in combo kits). The application class (A1) means random I/O speeds (very important when running an OS) have to meet a higher standard. There’s no benefit on the Pi for A2 right now so get whichever is cheaper/available.

Choosing a Linux Distribution

The most important consideration when choosing which flavor of Linux to run the server on is simple: available RAM. Headless Linux distributions such as Raspbian Lite that don’t have a built in GUI have

Our biggest obstacle when running a Minecraft server on the Pi is available RAM since 1 GB is extremely low for this type of server. To have a playable experience you should not be running anything else on the Pi so all memory is available to be used.

After testing on many different distros I am finding Raspbian Lite and Ubuntu Server 18.04.4 32-bit to be the best choices. These distributions come with very few background processes and have rock solid support and performance.

64-bit vs 32-bit

There’s a lot of discussion in the Pi world about the up and coming aarch64 64-bit distributions vs. armhf 32-bit distributions. They have been and continue to improve dramatically. There are already use cases where 64-bit is far superior such as video encoding, advanced compression, etc.

So how about for running a Minecraft server? I have been testing extensively with Ubuntu Server 18.04 64-bit and the Debian Buster 64-bit. I have consistently had worse performance and stability than on 32-bit versions of the exact same distros.

But how can that be? It’s certainly true that Minecraft servers benefit in CPU performance from 64-bit versions of Java. The answer is actually incredibly simple: memory. The server running on a 64-bit Java Virtual Machine uses a minimum of about 100 MB more memory. This makes perfect sense because 64 bits > 32 bits by definition!

The Raspberry Pi’s 1 GB of memory has been the biggest obstacle for this project since the very beginning. Back when I first went into the Paper Minecraft developer IRC room and told them what I was trying to do I was practically laughed out of the chat room for even thinking of trying this. Most Minecraft server branches including vanilla can’t even start on the Pi because of the limited memory.

For a dedicated Minecraft server on the Pi I very highly recommend staying 32-bit. You will have more available memory which means it will be much faster and more stable. Since memory is our bottleneck the increased CPU throughput does not help us and losing *any* of our memory is disastrous!

If the Raspberry Pi 4 has more memory like we all expect it to this recommendation will change completely. Even 2 GB of memory would make the extra memory that 64-bit uses a non-issue and the CPU throughput performance gains very desirable. For now though stay 32-bit for a Minecraft server!

Tested Distributions

Raspberry Pi OS – It’s Raspbian. It has very low memory usage and is the official distribution of the Raspberry Pi. The server runs very well on this. It’s overall the best choice. The Buster release has made OpenJDK 11 available on it so it’s no longer behind the rest of the distros.

Ubuntu Server 18.04 / 20.04 – Ubuntu Server is my favorite Linux distro. I use it for nearly all of my projects. The performance of the 32-bit armhf version is on par with Raspbian. It’s a great choice! Click here for my Ubuntu setup guide for Raspberry Pi. The 64-bit version is not a fantastic choice and not recommended because of the higher memory usage. Stick with 32-bit and you’ll be a happy camper with Ubuntu Server.

Debian Buster 64-bit – Debian is the distribution Raspbian is based on. This version is a preview of Debian “Buster” which is the successor to Stretch and will be the next version of Raspbian when it is released. I like this distribution but it is currently still unofficial and unsupported. Performance and stability was less than Ubuntu and Raspbian.

Minecraft Server Installation

SSH into your Raspberry Pi and paste the following commands:

curl https://raw.githubusercontent.com/TheRemote/RaspberryPiMinecraft/master/SetupMinecraft.sh | bash

The script will setup the Minecraft sever and ask you some questions on how to configure it. I’ll explain here what they mean.

“Enter amount of memory in megabytes to dedicate to the Minecraft server” – The amount of memory that will be dedicated to the Minecraft server. The more the better, but you must leave some room for the operating system background processes.

If you exceed the total available memory either the server will crash or the Pi will get incredibly slow to the point where your SSH session will start timing out. The setup script will make a recommendation to you which is your available memory – 10% for headroom. If you aren’t sure what to put just go with the recommended amount.

Note for Raspberry Pi 4: Currently on 32-bit Raspbian 2700 MB is the maximum that Linux will let us allocate in a 32 bit environment. The script has been updated to check for this as the server will not start if it is set over 2700M on a 32 bit server. 64 bit operating systems will be able to allocate all available memory as Pi 4 support rolls out for them.

“Start Minecraft server at startup automatically (y/n)?” – This will set the Minecraft service to start automatically when your Pi boots. This is great because whenever you want to play you can just plug it in and go without having to SSH in.

“Automatically reboot Pi and update server at 4am daily (y/n)?” – This will add a cron job to the server that reboots the Pi every day at 4am. This is great because every time the server restarts it backs up the server and updates to the latest version. See the “Scheduled Daily Reboots” section below for information on how to customize the time or remove the reboot.

That is it for the setup script. The server will finish configuring and start!

Check Java Version

Sometimes if you have multiple versions of Java installed the wrong version of Java will be selected as the default. If the server didn’t start check that the right version of Java is selected with this command:

sudo update-alternatives --config java

If you get the message “update-alternatives: error: no alternatives for java” then you only have one version of Java installed and can skip to the next section.

If you are presented with a list of choices then your machine has multiple versions of Java installed. It will look like this:

update-alternatives: warning: /etc/alternatives/java has been changed (manually or by a script); switching to manual updates only
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
  0            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1101      auto mode
  1            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1101      manual mode
  2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode

You will usually want to just select the newest version of OpenJDK that is listed so you would type 0 and press enter. In some cases on some platforms you may want to switch to the official Oracle JDK although I strongly recommend sticking with OpenJDK!

First Run

The first time you run the server it will take a little longer to start since it is generating all the server data. If you try to log in before it fully starts you will get a connection timeout error. Watch for the line: “Timings Reset”. This is the last line that prints when the server is ready to rock and roll. At this point you will be able to connect successfully.

The very first time you log into the server it will be slow for about 1-2 minutes. This is because since nobody has logged in before the server has to scramble to generate all the chunks within your view distance (10 by default) and send them to you/store them. During this time you may not be able to see very far and if you try to destroy blocks there will be noticeable lag from when they break to when they actually disappear.

Don’t panic! This will go away within a couple of minutes as the Pi catches up with all the first time login stuff it needs to do. Performance stabilizes and it will feel very much like the offline experience after that.

If you are hosting for a few friends I’d recommend logging in for the first time right after you set up the server instead of having several people nail a blank server at first startup. This gets it out of the way and when everyone is ready to log in the starting area chunks will be fully fleshed out and the Pi just has to read them. It’s an order of magnitude faster for the Pi to read chunks than to generate and store chunks.

In my experience after the initial login exploring new parts of the server doesn’t cause any lag even though new chunks are being generated. The reason for this is that when you’re walking it’s really only having to generate a new chunk as you get close to the border instead of a huge square area of chunks in all directions and all at the same time like during the first login.

Benchmarking / Testing Storage

If you’re getting poor performance or just want to verify everything is working correctly you may want to run my storage benchmark with:

sudo curl https://raw.githubusercontent.com/TheRemote/PiBenchmarks/master/Storage.sh | sudo bash

If you search for the model of your drive on pibenchmarks.com you can compare your score with others and make sure the drive is performing correctly!

Changing Minecraft Server Version

To override the default version let’s grab a copy of the script locally:

wget https://raw.githubusercontent.com/TheRemote/RaspberryPiMinecraft/master/SetupMinecraft.sh 
nano SetupMinecraft.sh

Now make these changes from inside nano:


Now press Ctrl+X to exit nano and answer “y” to save. Now let’s run the script:

chmod +x SetupMinecraft.sh

And the setup will run and install the version of Minecraft you set at the top of the file!

Changing Minecraft Client Version

If you are wisely running the “stable” branch instead of the “development” branch there will be times where you need to select the version of Minecraft to run otherwise you will get an error message that your client is outdated when you try to log in.

Fortunately this is very easy. Open up the Minecraft launcher and instead of hitting “Play” choose “Launch Options” in the menu at the top of the window. It will look like this:

Minecraft launch options
Minecraft Launcher “Launch Options” Tab

Click the “Add new” button and pick which version you want to add. You can optionally gave it a name or just click save.

Now when you go back to the “News” tab you will see a dropdown arrow where you can select which version of Minecraft you want to play!

Start, Stop and Restart Server

The server can be started, stopped and restarted two different ways. You can use the provided scripts in the Minecraft folder or you can use systemctl. Here are the commands:

cd ~/minecraft


sudo systemctl start minecraft
sudo systemctl stop minecraft
sudo systemctl restart minecraft

Automatic Backups

The server backs up each time it starts. This helps you recover easily if something goes wrong. This system works best if you configured the server to restart daily since it means you will have a backup every day.

To access these backups type:

cd ~/minecraft/backups

When a backup is made the filename will be the date and time the backup was taken. If you need to restore a backup it’s very easy. Substitute the timestamp in my example to the backup you want to roll back to. Type:

cd ~/minecraft
rm -rf world world_nether world_the_end
tar -xf backups/2019.

Your world has now been restored! It’s a good idea to download these backups off the Pi periodically just in case the Pi’s storage fails.

Scheduled Daily Reboots

The daily reboots are scheduled using cron. It’s very easy to customize the time your server restarts.

To change the time that the server restarts type: crontab -e

This will open a window that will ask you to select a text editor (I find nano to be the easiest) and will show the cronjobs scheduled on the Pi. The Minecraft one will look like the following:

0 4 * * * /home/ubuntu/minecraft/restart.sh
cron options

There are 5 fields here. The default restart time is set to reboot at 0 minutes of the 4th hour of the day (4 AM). The other 3 fields are left as * to represent every day of every month. Make any desired changes here and press Ctrl+X to exit nano and update the cronjob.

To remove the daily reboot simply delete the line and save.

Installing Mods / Plugins

The server supports plugins that are compatible with Bukkit / Spigot / Paper. A popular place that you can get plugins is at dev.bukkit.org where there are thousands of them!

To install a plugin you simply download the .jar to the minecraft/plugins folder and restart the server. For example, WorldGuard is a very popular plugin that lets you add protection to different areas of your server.

To install this plugin on our Minecraft server we would use the following commands:

cd ~/minecraft/plugins
curl -H "Accept-Encoding: identity" -H "Accept-Language: en" -L -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ Safari/537.36" -o worldguard.jar https://dev.bukkit.org/projects/worldguard/files/latest
sudo systemctl restart minecraft

The reason the middle line is so long is that “robots” (roughly anything that isn’t a web browser being used by a user in this context) including scripts and utilities are blocked by the Bukkit server. The extra parameters we’re including in this line will add the location (-L) flag as well as a user agent and an identity / language header which will allow us to fetch the files without getting a 403 forbidden error.

Make sure to change “-o worldguard.jar” (second to last parameter) and the URL (very last parameter) to match the project you want to download.

The server will restart and the plugin will be installed. It’s that simple! To use the plugin refer to the documentation on the plugin download page to find out which commands you use to configure/interact with it.

Warning: be advised that plugins are the #1 issue for performance degradation on Minecraft servers. This isn’t because all plugins are bad. Some plugins are coded very inefficiently or perform features that require a lot of hooks in the code.

You should be careful about what plugins you install on the server and if you start having bad performance disable your plugins one by one until you find the culprit!

Reconfigure / Update Scripts

The scripts can always be reconfigured and updated by downloading the latest SetupMinecraft.sh and running the installer again. It will update all of the scripts in the Minecraft directory and reinstall the startup service for you.

Running SetupMinecraft.sh again will also give you a chance to reconfigure options such as the memory dedicated to the server, daily reboots, starting the server on boot, etc.

This will not overwrite your world or any other data so it is safe to run!

Port Forwarding

If everyone on your server is on the same LAN or WiFi network as you then you don’t need to do this. If you want people to connect from outside your local network then you need to set up port forwarding on your router.

The process for this is different for every router so the best thing to do is just look at your router and find the model # and put that in google with port forwarding for easy instructions on how to do it for your specific router.

You want to forward port 25565. The type of connection is TCP if your router asks. Once you do this people will be able to connect to your Minecraft server through your public IP address. This is different than your local IP which is usually a 192.x.x.x or 10.x.x.x. If you don’t know what that is just go to google and type “what’s my ip” and Google will kindly tell you!

Wired vs. Wireless

Going with an ethernet (wired) connection is going to be faster and more reliable. There’s so much wireless traffic and other interference in the air that running your server on WiFi is not recommended.

Even if it is working great 99% of the time it can ruin your experience very quickly if the WiFi drops for a couple of seconds and you get blown up by a creeper!

All that being said, the server works fine on wireless. The script will work fine as is with a wireless connection.


PLEASE BACK UP YOUR SERVER FIRST! The server makes automated backups by default for you in the backups folder but I recommend you back up the entire server folder yourself (basically the entire minecraft folder) any time you attempt to upgrade or downgrade. If you need to roll back to older versions it won’t work without a backup from that version or older!

The easiest way to upgrade an installation is to download the latest SetupMinecraft.sh and run it. This will automatically upgrade you to the latest version.

Upgrading and downgrading to versions that aren’t the default the script chooses is pretty simple. Simply change the Version line at the top in the SetupMinecraft.sh script:

# Minecraft Server Installation Script - James A. Chambers - https://jamesachambers.com
# More information at https://jamesachambers.com/raspberry-pi-minecraft-server-script-with-startup-service/
# GitHub Repository: https://github.com/TheRemote/RaspberryPiMinecraft

# Minecraft server version

Edit this file in your favorite text editor (you can use nano or vi on the Pi like nano SetupMinecraft.sh) and change the Minecraft version to what you want.



If you are having problems on a newer version of Minecraft and want to downgrade you can do so using a complete backup of your server before you ran it on a newer version.

The reason you can’t take server data that has been touched by a version such as 1.17 and go back to 1.16 is that the new version adds all sorts of new data types/structures for the new content into your server data files. If you try to roll back the old versions of the Minecraft server will not understand these data types since they didn’t exist in that version and will crash.

As long as you use a backup for your server files from that version (or older) it’s as simple as changing the version in SetupMinecraft.sh just like I show in the “Upgrading” section.

You can upgrade any old version of Minecraft to any version, but again make sure you have a backup first as it is a one way street and you will need that backup if you want to roll back!

Troubleshooting Note – Oracle Virtual Machines

A very common problem people have with the Oracle Virtual Machine tutorials out there that typically show you how to use a free VM is that the VM is much more difficult to configure than just about any other product / offering out there.

It is because there are several steps you need to take to open the ports on the Oracle VM. You need to both:

  • Set the ingress ports (TCP/UDP) in the Virtual Cloud Network (VCN) security list
  • *and* set the ingress ports in a Network Security Group assigned to your instance

Both of these settings are typically required before you will be able to connect to your VM instance. This is purely configuration related and has nothing to do with the script or the Minecraft server itself.

I do not recommend this platform due to the configuration difficulty but the people who have gone through the pain of configuring an Oracle VM have had good experiences with it after that point. Just keep in mind it’s going to be a rough ride through the configuration for most people.

Troubleshooting Note – Hyper-V

There is a weird bug in Hyper-V that breaks UDP connections on the Minecraft server. The fix for this is that you have to use a Generation 1 VM with the Legacy LAN network driver.

Hi! It’s me again, lol.
I have a question. Since my backups are quite big (around 15GB) and I only own a 128gb nvme, is it possible to route the backups to an external drive? I know this will slow things down but it’s kinda frustrating to go to ftp and delete the backups manually every now and then. Thank you! 🙂

1 year ago

Hi! So I set everything up and now I need to reload a backup. Is the command for this just tar -xf backups/mytimestamptar.gz ?

1 year ago

Okay now the server won’t start it just flashes really quick after downloading paper. Then the following appears in the console: you are using a headless JRE distribution. This distribution is missing certain graphic libraries that the minecraft server needs to function.” Any ideas how I can fix this issue? Thank you for your help! <3

Hi! So Im using the Pi now for several years with your script and it works wonderfully. However, when I travel fast with the elytra, the map cant keep up generating and I often fly in the void and have to wait a little till it’s getting rendered. Even when the chunks are preloaded with the plugin chunkgen I have this problem. Is there a solution so the map gets loaded faster? Maybe a faster SSD or other storage solution? Is the writing speed the limit or the cpu/ram? Also, do you know a similar solution like the raspberry pi but a little faster or more powerful, but not a full server computer? Thank you for your time and your dedication for this wonderful script! Have a nice day and greetings

Hey! So Im located in Europe and I see no option to buy it. Maybe I can ship it to here. I only find this one and Its more expensive.
Can you maybe send me a link to the one I should order and is there a EU option?

1 year ago

Thanks for the detailed reply! So I finally found a good offer from the states and they ship to Europe. I also bought the Toshiba nvme card from your orange pi blog post. This is the device I ordered I hope that’s the correct one?
Also, is there a Guide for setting up a Java server on the orange pi? I’m looking forward to see how fast the nvme is compared to my old ssd on the rasppi 4.

1 year ago

Thank you! Also, is there a way to just transfer the Server I’m running right now to the new orange pi without reconfigurations? Also, I have a Dynmap running which is approx. 20-30gb big and has over 30m files which would take ages to transfer so I’m thinking to just exclude the dynmap and let it render again on the new Pi? Last question; should I just leave all settings the same or is it necessary or even recommended to tweak them a little to make them more fitting to the orange pi? Like render distance etc. or a different OS?

1 year ago

Awesome I’ll do it like you say. And for the OS, due to having 4gb of ram and the orange being more powerful, should I use a 64 bit operating system, and which one would you recommend? I hope I’m not annoying with all my questions! 😀

Hey James! I have been using your website heavily as I learn more about my new Raspberry Pi 4. I am running into an issue that I can’t figure out when trying to get this set up. The server never seems to start and I have no logs being generated. I have a full install log here along with some other useful info that I have seen you reference in other comments while I was search through to try and troubleshoot.

The thing that stands out to me in the install log is this:

bash: line 323: [[: bash: line 322: /home/admin/minecraft/jre/bin/java: No such file or directory: syntax error in expression (error token is ": line 322: /home/admin/minecraft/jre/bin/java: No such file or directory")

But I am not sure what to do about that. When I use cd it certainly looks like that path exists:

admin@pihole:~/minecraft/jre/bin $ tree
├── java
├── jfr
├── jrunscript
├── jwebserver
├── keytool
└── rmiregistry

0 directories, 6 files

You can also see that trying to run paperclip.jar straight through java also gives me an error at the end.

Sorry if this is already addressed! I wish there was an easy way to search all of the comments on here. I appreciate the hard work you’ve done and shared with us!

Thanks for the quick reply! I will definitely look into the Docker install, but the sudo apt install docker-ce returns an error that there is no valid target.

I was hoping to get something up to test with some other players this evening, so I tried the install again and it failed with the same error. I am running it exactly copy and pasted with bash, not with sh.

I went ahead and manually deleted the entire /minecraft directory and everything in it, then ran the script again to start complete blank. This is what I got this time:

Hi James,

Thank you so much for you hard work putting this guide together, I’ve learned so much in the past couple days! I’m trying to run a server for myself and a couple friends on a RPi 4 Model B with 1 GB of RAM, using Bullseye Lite on your recommend Kingston A400 SSD with the StarTech adapter. So far, I’ve found it pretty much impossible to run 1.19, with max memory of 700 MB the Pi is extremely slow over SSH but runs the server, however mobs are severely lagging to the point where it’s unplayable. Any other tricks you’d suggest, or should I give up and run 1.12 or something? Also wondering what your thoughts were on adding more swap as described here.

Hi James, for uname -a I have armv7, so 32 bit. I don’t have any mods/add-ons installed. Thanks for sending that guide over, I’ll check it out! CPU usage was around 190% last time, so it would make sense that CPU is struggling.

Hi ! Thank you for your great work, the tutorial is clear and well written.
I have a problem however : when starting the server, it seems to crash during the ” Preparing level “world” ” step (monitoring with screen).
I use a Pi 3B+ with a 64GB Kingston micro SD card.
I did the installation several times, testing different memory allocations, and nothing changes.
Here is the log :
[12:23:25] [ServerMain/INFO]: Building unoptimized datafixer

[12:26:53] [Server thread/INFO]: Server permissions file permissions.yml is empty, ignoring it
[12:26:53] [Server thread/INFO]: Preparing level "world"

The weird thing is that it actually started once, and I managed to play for about 20 minutes, before being disconnected and not being able to launch the server again.
The only mod I downloaded is, as you can see, Chunky, but it’s the same without the mod installed.
Any idea where the error could come from ?
Thank you very much !

Thank you for your very fast answer !
Okay, I assumed it crashed since it didn’t launch, I get the difference now.
Here is the free command :
~ $ free
total used free shared buff/cache available
Mem: 944268 56280 373512 964 514476 834324
Swap: 102396 0 102396

So yes that seems to be the problem !
The thing is that the script does not let me put less than 600MB of memory… So my previous log was an attempt at 600.
I noticed before that the recommended amount for my system was around 400MB, but since you wrote “A minimum of 700MB is recommended”, and that I couldn’t actually put less than 600, I thought it was normal..!
So what is the solution to bypass that 600MB limit ? And do you think the Pi3B+ will still work properly for the purpose of a Minecraft server ?

Ok I figured it out! hahaha

To access your server terminal you need to type screen -ls and you will get a list of screened processes.

With that take the number and type: screen -r $number

And it will load the process that has been detached from terminal to be able to close all ssh connections and keep running!

With that you can OP you user with: op %user

And just execute commands ingame without the need to re-open the terminal + screen to access the server command line
