Build a Minecraft server with Raspberry Pi

A Raspberry Pi Minecraft server is one of the most satisfying Pi projects because the result is immediately social.

You are not just blinking an LED or spinning up a demo service. You are making a shared world that friends, siblings, kids, or a small online group can actually use.

That said, this is one of the most oversold Raspberry Pi projects on the internet.

A Pi can run a Minecraft server. It cannot magically become a high-end dedicated game host just because somebody on a forum once squeezed twelve players into a benchmark test for fifteen minutes.

If you treat it like a small, private, low-cost server and build around that reality, it works surprisingly well.

What a Raspberry Pi Minecraft server is good for

This project makes sense if you want:

• a private survival world for family or friends
• a low-cost server that can stay on all the time
• control over backups, whitelist, rules, and plugins
• a practical way to learn Linux, networking, and service management
• a fun weekend project that stays useful after setup

Those are great reasons.

What it is not good for

A Pi is the wrong tool if you want:

• a big public server with lots of random players
• huge modpacks and heavy automation everywhere
• giant render distances with constant exploration
• the lowest possible lag under every condition
• zero maintenance forever

A Raspberry Pi server is best when the world is small and intentional.

The hardware I would actually use

Best starting point: Raspberry Pi 4

A Raspberry Pi 4 is where this project starts to feel genuinely reasonable.

• 4GB RAM is enough for a small world with a few players
• 8GB RAM is better if you want extra headroom for Java, plugins, and the operating system

If you already own a Pi 4, use it. If you are buying specifically for this project, I would lean toward the 8GB model if the price difference is sensible.

Can you use older Pis?

Yes, technically.

But older boards turn the project into more of a compromise:

• fewer players
• worse chunk generation performance
• more lag spikes
• less tolerance for plugins or background services

If you only have a Pi 3, I would keep the server very small and expectations even smaller.

Storage matters more than people expect

Minecraft worlds are a lot of small file activity, and poor storage can make the whole server feel worse.

My preference:

• Raspberry Pi OS on good storage
• world files on a reliable SSD if possible
• microSD only if the rest of the setup is modest and you keep backups

You can absolutely start on microSD. I just would not pretend it is the best long-term home for a world people care about.

Cooling and power are not optional details

If a Pi is running a server all day, use:

• a trustworthy power supply
• a case with airflow
• active cooling if possible
• ethernet instead of Wi-Fi when available

A lot of random server weirdness is really heat, power, or flaky storage.

Set realistic performance expectations

This is the part that decides whether you enjoy the project or resent it.

A Raspberry Pi Minecraft server is usually happiest with:

• a few regular players
• a modest map size
• reasonable render and simulation settings
• limited redstone chaos
• light plugin use instead of giant modded complexity

If one player constantly flies off generating new chunks while someone else runs a massive farm and a third person is testing contraptions, the Pi will remind you that it is still a tiny computer.

That does not mean the project failed. It just means server discipline matters.

Paper vs vanilla: pick the boring smarter option

For most people, I would use Paper.

Why Paper is usually the better choice

Paper gives you:

• better performance than vanilla
• more configuration controls
• plugin support
• lots of community documentation
• a better chance of keeping a Pi-based server stable

When vanilla still makes sense

Use vanilla if you specifically want:

• the most stock Minecraft experience
• no plugins at all
• the fewest moving parts

That is valid, but on constrained hardware, efficiency matters. I would not make the Pi work harder just to be ideologically pure about server software.

The setup flow I would follow

1. Prepare the Pi as a boring stable Linux box first

Before Minecraft touches the machine, do the boring admin work.

Update the system:

sudo apt update
sudo apt full-upgrade -y

Install Java:

sudo apt install openjdk-17-jdk -y
java -version

At this stage, also make sure:

• the hostname is sensible
• SSH works if you want headless admin
• the Pi has a stable IP or DHCP reservation
• storage is mounted where you expect it to be

A game server built on top of a messy base system becomes a troubleshooting hobby fast.

2. Create a dedicated server directory

I like keeping the project contained:

mkdir -p ~/minecraft-server/{backups,logs,scripts}
cd ~/minecraft-server

Simple structure now saves confusion later.

3. Download the server software deliberately

For Paper, use the official Paper downloads page or API and keep the JAR naming simple.

Example flow:

wget https://api.papermc.io/v2/projects/paper/versions/1.20.4/builds/497/downloads/paper-1.20.4-497.jar
mv paper-1.20.4-497.jar server.jar

The exact version changes over time. The important habit is using a real current release, not some random mirrored file from a guide written ages ago.

4. Create a sensible startup script

A simple script is enough:

nano start.sh

Example contents:

#!/bin/bash
cd /home/pi/minecraft-server
java -Xms1G -Xmx3G \
  -XX:+UseG1GC \
  -XX:+ParallelRefProcEnabled \
  -XX:MaxGCPauseMillis=200 \
  -jar server.jar nogui

Then:

chmod +x start.sh

You do not need to become a JVM tuning philosopher here. Keep it sane and move on.

5. Run it once, accept the EULA, then configure properly

First launch:

./start.sh

It will stop and generate files. Then edit:

• eula.txt and set eula=true
• server.properties

This is where the Raspberry Pi-specific decisions matter.

The server.properties settings that matter most

If you are running on a Pi, conservative settings are your friend.

Useful starting points:

motd=Welcome to our Raspberry Pi Minecraft Server!
max-players=6
view-distance=8
simulation-distance=6
white-list=true
online-mode=true
enable-command-block=false

Why these settings matter

• max-players keeps expectations aligned with hardware
• view-distance has a big effect on server load
• simulation-distance helps control background work
• white-list keeps random people out
• online-mode should stay enabled for normal legitimate use

A Raspberry Pi server gets better when you make fewer heroic promises.

Network access: local only vs remote access

This is the second-biggest decision after hardware.

Option 1: local network only

This is the easiest and safest version.

Great for:

• kids in the house
• siblings
• roommates
• friends visiting locally

If that is your use case, you can stop here and enjoy the project with much less risk.

Option 2: internet access for remote friends

This is where people usually jump straight to port forwarding.

It works, but it is not the only option and often not the safest one.

For a small private server, I prefer:

• VPN access
• private network tools like Tailscale
• other limited-access approaches

These reduce the chances of turning a home game server into a public scanning target.

If you do port forward, at least:

• keep the server whitelisted
• keep the Pi updated
• avoid reusing admin passwords anywhere
• know how to shut the service down quickly

Use a systemd service so the server behaves like a real service

Instead of manually starting the server every time, create a service:

sudo nano /etc/systemd/system/minecraft.service

Example:

[Unit]
Description=Minecraft Server
After=network.target

[Service]
User=pi
WorkingDirectory=/home/pi/minecraft-server
ExecStart=/bin/bash /home/pi/minecraft-server/start.sh
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target

Then enable it:

sudo systemctl daemon-reload
sudo systemctl enable minecraft.service
sudo systemctl start minecraft.service
sudo systemctl status minecraft.service

This makes the box feel much less like a hobby script and much more like a real server.

The best performance wins on Raspberry Pi are the unglamorous ones

People love hunting for exotic optimizations. Most of the useful wins are boring.

1. Keep player count modest

The fastest way to improve performance is simply not oversubscribing the hardware.

2. Use ethernet

Minecraft traffic is not huge, but wired networking is more stable and easier to reason about.

3. Put the world on better storage if possible

Slow storage hurts backups, chunk writes, and general responsiveness.

4. Keep view distance under control

Huge view distances feel nice until the server starts struggling.

5. Avoid turning the world into an industrial stress test

A private server full of giant farms, automatic sorting systems, and constant exploration is much harder to keep smooth.

Backups are the difference between a fun project and a regret story

If more than one person plays on the server, assume the world matters.

That means backups matter too.

At minimum, I would:

• schedule periodic world backups
• keep multiple older copies
• store backups somewhere other than the main live folder
• copy important backups off the Pi occasionally

A simple approach is a script that stops or saves the world cleanly, creates a compressed archive, and keeps only the newest set.

Even a basic backup routine is better than discovering corruption after months of play and having no plan.

Common problems and what usually causes them

The server starts but feels laggy

Usually:

• too many players
• view distance too high
• world generation happening constantly
• storage or thermal throttling

Players disconnect randomly

Usually:

• weak Wi-Fi
• power instability
• overheating
• router or port-forwarding issues

The server uses too much RAM

Usually:

• Java allocation set too aggressively
• too many plugins
• expectations too high for the board

The world corrupts after a crash or power cut

Usually:

• no UPS
• unsafe shutdown
• no backup discipline

Everything worked until someone built something huge

Also normal.

Minecraft server load is not just about player count. It is about what those players build and where they roam.

Security and access habits I would actually recommend

For a home Raspberry Pi Minecraft server:

• use a whitelist
• keep it private unless there is a good reason not to
• update the system regularly
• do not expose unrelated services on the same box
• avoid using the Pi for lots of random extra jobs if this world matters to people

A Pi can multitask, but every extra service creates more ways for your simple game server to become a messy little server farm.

Who should skip this project

Skip it if:

• you want a large public Minecraft community server
• you do not want to do updates or backups
• your internet upload is poor and remote play is the whole point
• everyone involved is sensitive to lag and expects polished hosting-company performance

In those cases, a cheap VPS or commercial Minecraft host may simply fit better.

What I would build today

If I were doing this from scratch right now, I would keep it very grounded:

• Raspberry Pi 4 with active cooling
• Paper instead of vanilla
• ethernet, not Wi-Fi
• whitelist enabled
• view distance kept modest
• remote access only through a safer private-access method if possible
• scheduled backups from day one

That is not the most dramatic version of the project.

It is the version most likely to stay fun.

The honest bottom line

A Raspberry Pi Minecraft server is absolutely worth building if you want a small private world and you accept the hardware for what it is.

Do not build it because some tutorial promised a tiny miracle box that can host endless players forever. Do not build it because you want a public-server flex. Do not build it with zero backup plan and then act shocked when power trouble ruins your week.

Build it because you want:

• a cheap shared world
• more control over the server
• a good way to learn Linux and networking
• a practical project with a social payoff

That version still holds up really well.
