How to Run a Minecraft Server on Raspberry Pi?

Let’s start by preparing your Raspberry Pi to act as the dedicated server. Then, you’re ready to run a Minecraft server on it. This means getting the right software installed, configured, and tuned for the best performance as well as providing them a stable source of network access.

Author's Note: A Raspberry Pi 4 with at least 4GB of RAM is recommended to ensure the best gameplay. Utilizing this powerful little device, you’ll be able to create a low-cost and energy-efficient server that friends, family, or the entire community can use!

Why Host Minecraft on Raspberry Pi?

Hosting a Minecraft server on a Raspberry Pi offers a unique blend of cost efficiency, energy savings, and learning opportunities. This approach stands out as a practical solution for small-scale servers, especially for those wanting to explore technical skills and customization without relying on commercial hosting services.

Here are some of the most important advantages—let’s explore them in more detail.

Cost and Energy Efficiency

Using a Raspberry Pi for hosting greatly cuts down the costs of using a typical hosting service. Commercial hosting platforms commonly charge a monthly fee from $5-$25 or higher, based on server size and expected performance.

Other than the initial setup of $50-$100 one-time investment, depending on what model you go with—Raspberry Pi 2, 3, 4, or 5—there are no additional costs to maintain. Be sure to consider the cost of accessories, too! You’ll pay for the whole thing up front, but you avoid making ongoing payments for what could be years of use.

The Raspberry Pi’s energy efficiency is a third major point in its favor. During operation, it uses just 3 to 5 watts. This low power consumption makes it ideal for 24/7 use, consuming less electricity than a standard light bulb.

In the long run, the money saved on energy costs pays for itself, leaving you with a greener, smarter option. For small scale servers and those just hosting 2-5 players, this is a very cost effective and efficient way to do so.

Learning and Customization

In addition to the engaging and immersive learning experience that Minecraft play provides, setting up a dedicated Minecraft server on a Raspberry Pi gives teens real-world experience. From configuring a static IP address to troubleshooting performance issues, it is an immersive process that instills creativity and perseverance alongside technical acumen.

For instance, the use of plugins such as PaperMC can greatly optimize server performance and allows server operators to tinker around with advanced settings. Customization is where Minecraft really shines.

Custom gameplay possibilities, server settings, and plugins provide you with control over gameplay, allowing customized experiences for friends or private groups. Tackling projects such as developing custom mods or learning basic programming are further challenges that can hook kids and turn Minecraft into an enriching family experience.

Privacy and Control

With self-hosting, you have total control over your player data and the customization of your server. This solution removes reliance on outside platforms and their privacy management.

Host a secure, private server just for your friends or family! You can invite up to ten of your children’s friends, or just have a more cozy gaming experience with a smaller group of two to three players.

Essential Equipment for Your Server

Hardware ConsiderationsStorage ConsiderationsNetworking Considerations Considerations

Every component is crucial in maintaining seamless performance and a lag-free, stable server experience. Below, we’ll unpack these essentials to ensure you know what to look for and make the right decisions.

Raspberry Pi Model Selection

Selecting the appropriate Raspberry Pi model affects your server operation and ease of use. The Raspberry Pi 4 is the hands-down winner of the bunch. With a powerful quad-core processor and up to 8GB of RAM, it’s a beast.

These features give developers the flexibility and power they need to gracefully support thousands of players and a third-party plugin ecosystem. Older models like the Raspberry Pi 3 can realistically handle running a server. However, their 1GB RAM and lower processing speed often make for a laggy gameplay.

For small-scale servers hosting up to five players, a Raspberry Pi 4 with 4GB RAM offers an excellent balance between cost and capability. If your budget permits it, the 8GB version provides more room for flexibility down the line or for more advanced use cases.

Storage and Memory Needs

This highlights the vital role that storage plays in keeping your server performing at its best. At least a high-speed (Class 10 or higher) microSD card with at least 16GB of capacity is required.

If you require faster read/write speeds, use an external SSD connected via USB. This is important for reducing latency, particularly when saving world data or processing backups. Allocating enough RAM is just as critical.

Editing the new “config.txt” file to allocate additional memory to the GPU boosts graphics performance. Servers with many players or plugins require more RAM, as it stops random crashes and leaves your server more dependable. Here’s a quick list of storage options:

• SanDisk Extreme microSD cards (16GB or larger)
• Samsung T5 Portable SSD
• WD My Passport SSD

Networking Essentials

The quality of a network connection has a direct impact on the quality of gameplay and server experience. A wired Ethernet connection would be best to avoid latency and potential packet loss.

If Wi-Fi is your only choice, make sure you optimize your router settings. For example, pick a channel with less congestion, and you will see your server connectivity increase. Having a router you can trust paired with a good Ethernet cable will go a long way towards maintaining a great connection, even during intense multiplayer matches.

Forwarding the server port on your router allows players outside your local network to connect.

Power Supply Considerations

Without lots of reliable, predictable power, most server applications can’t sustain unexpected shutdowns. Use an official Raspberry Pi power supply, or a trusted brand replacement with the same voltage and at least equal to or higher amp rating.

Since power fluctuations can immediately affect gameplay, a UPS protects from unexpected outages, making it a worthwhile investment. Secondly, a stable power source is essential to maintain the smooth operation of your server.

Operating System and Software Setup

Getting your Raspberry Pi set up to host a Minecraft server is going to take some preparation with the operating system and software. The appropriate operating system can have a big impact on server performance. Having all the dependencies in place and adjusting the settings will help things run smoothly and efficiently.

We’ll look at each element in-depth below to help you navigate the setup process.

Choose Your OS

The operating system is key in creating a stable Minecraft server. Raspberry Pi OS Lite provides a lightweight, minimal OS environment that’s ideal for power users and resource-intensive projects. It’s a great option for hosting gaming servers.

Alternatively, Ubuntu Server is another good choice, known for its excellent support and compatibility. Both alternatives omit a graphical user interface (GUI). For users, this omission is a key benefit since it allows the system to save resources by booting directly into a terminal.

For clarity, consider these features when deciding:

• Lightweight OS The sooner the server can get to a request, the better.
• Operating without a GUI simplifies management and reduces overhead.
• Community support: Popular OS options often have extensive documentation and forums.

Install Required Dependencies

In order to host a Minecraft server, a few software dependencies are necessary. The most important of these is the Java runtime, since Minecraft itself is a Java application. Start off by refreshing your system with sudo apt update && sudo apt upgrade.

Then, install Java with the following command: sudo apt install openjdk-17-jre-headless

Regularly updating your dependencies is an important practice for ensuring compatibility and security. You’ll want some convenient utilities, such as a screen for running the server in the background.

Install it using: bash sudo apt install screen

Other handy packages are wget to download remote files, and unzip to expand compressed server files.

Configure Raspberry Pi Settings

Tuning the Raspberry Pi’s internal settings helps maximize the overall performance of your server. Set up SSH to allow you remote access so that you can manage the server without needing to be physically connected.

Access the settings by entering the command sudo raspi-config. You can further improve security by updating the default username and password. Lastly, enable the server to start automatically on boot.

Run it using the nohup command so that it doesn’t depend on your SSH session staying open.

1. Install Minecraft Server Software

If you have an interest in both creativity and technical skills, then running a Minecraft server on a Raspberry Pi is an engaging project. To make sure you get the smoothest experience, you must install the appropriate server software and set it up properly. This section walks you through all the necessary steps.

You’ll find step-by-step walkthroughs for downloading the server files and getting the server up and running for the first time.

1. Download the Server Files

To start, you’ll need to download the server software. Option 1 is to download the official Minecraft server software. Alternatives such as Spigot or PaperMC generally perform better on Raspberry Pi due to their performance optimizations and strong plugin support.

To be safe, always download your server files from the official website of the software. Using wget makes this process a lot easier. For example, to download the latest PaperMC build, you can use this command:

wget <https://papermc.io/api/v2/projects/paper/versions/>/builds//downloads/paper-\-.jar

Replace and with the latest numbers found on the PaperMC site. Make sure the source is trusted to prevent downloading a corrupted or malicious file. Here's a quick command list for downloading:

• sudo apt update && sudo apt install wget
• Download server jar: Use the wget command above with the correct version.

2. Accept the EULA

First, you need to agree to the Minecraft EULA. After running the server jar file for the first time, there will be a file called eula.txt that gets created. Open it using a text editor like nano:

nano eula.txt

Find eula=false and set it to eula=true. Skip this step, and you can’t run your server. Keep in mind that by accepting the EULA, you are indicating your acceptance of Minecraft’s terms.

Checklist for EULA compliance:

• Run the server once to generate eula.txt.
• Edit and set eula to true.
• Save and close the file.

3. Configure Server Properties

By customizing server.properties, you can tailor the gameplay to your liking. Open the file with nano:

nano server.properties

Key settings include:

• difficulty: Easy, Normal, or Hard.
• gamemode: Survival or Creative.
• max-tick-time: Set -1 to disable the internal watchdog.

Other changes, such as assigning a static IP address, improve the server’s stability.

4. Start the Server

Finally, start the server using this command:

java -Xms1G -Xmx1G -jar paper-\-.jar

Monitor your logs frequently to catch any errors. To ensure everything is stable, we recommend testing by restarting the Raspberry Pi.

With some plugins and tweaks, even something like a Raspberry Pi 5 can handle 10 players just fine.

Network Configuration for Accessibility

In order to host a Minecraft server on your Raspberry Pi, you need to set up your network the right way. With this configuration, users beyond your local network will be able to connect without any fuss. This includes assigning a static IP address for the hotspot, setting the router for appropriate port forwarding, and testing various connectivity options.

Each move is important for ensuring early general availability of a stable, accessible server environment.

Assign a Static IP Address

A static IP address is very important in keeping the connection between your router and Raspberry Pi consistent. Without it, your router might assign a new IP address to the device each time it restarts, disrupting the server’s accessibility.

To start, you’ll want to figure out what your current local IP address is by simply entering hostname -I in the terminal. This will tell you the IP address your router assigned to the Raspberry Pi.

To set up a static IP on your Raspberry Pi, you’ll want to modify the dhcpcd.conf file. Now add a block of code detailing what IP address you’d like the machine to use, gateway, and (optionally) DNS servers. For example:

The addition we made was simply with this interface, and therefore only affects eth0 in this line.

Save and reboot the Raspberry Pi to apply the changes. For the best performance, especially if connected directly to a server, we recommend using a wired Ethernet connection.

Checklist for Static IP Setup:

• Find the current IP address using hostname -I.
• Edit the dhcpcd.conf file with static IP details.
• Save changes and reboot the Raspberry Pi.
• Verify the new static IP is active.

Configure Port Forwarding

Setting up port forwarding lets the outside world know that your Minecraft server is available. Open your router’s admin panel — often by typing in the default gateway address (like 192.168.1.1) in a web browser.

In the port forwarding section of your router, create a rule that forwards port 25565 to the static IP address you set your Raspberry Pi to. That’s because this is the default port that’ll be used by Minecraft servers by default.

Each router model will have a different interface, but you should be able to find something that says “Virtual Server” or “NAT Forwarding.” Once you have defined the rule, make sure to save and apply changes.

Common Port Forwarding Details:

• External Port: 25565
• Internal IP: Raspberry Pi static IP
• Protocol: TCP/UDP
• Rule Name: Minecraft_Server

Test External Connectivity

Testing for external connectivity is exercised to make sure the server is accessible to players. Utilize tools like “CanYouSeeMe” to test for open ports online. Specify TCP port 25565 and test the connection.

If there are still problems, ensure the static IP, port forwarding configuration, and Ethernet cables are correct.

Connectivity Test Checklist:

• Use “CanYouSeeMe” to check port 25565.
• Confirm static IP and port forwarding settings.
• Ensure all cables are securely connected.

Optimize Minecraft Server Performance

Running a Minecraft server on a Raspberry Pi is an impressive yet delicate task, demanding precise adjustments to ensure stability and smooth gameplay. With significantly more restricted resources than conventional server hardware, optimization is a necessity. Free up your Raspberry Pi’s resources by optimizing memory distribution and server configurations.

Deploy real-time optimizations to deliver a seamless and stable Minecraft hosting experience. Here are some effective ways to bring a little more equity into your practice.

Allocate Sufficient RAM

Allocating the right amount of RAM is one of the most important basics for your server performance. Minecraft servers are memory-intensive, and a lack of dedicated memory can cause crashing, particularly when using the newest server versions.

To adjust RAM, modify the server’s startup command using flags like -Xms and -Xmx to set the minimum and maximum memory. For example, a Raspberry Pi with 4 GB RAM can allocate 2 GB (-Xmx2G), leaving enough for the operating system.

If you’re on a headless setup, consider lowering your dedicated video memory to 16MB to free up extra RAM. For very small servers (for 2-3 players), go with 512 MB to 1 GB to start.

Checklist:

• Recommended storage capacity: Use high-speed microSD Class 10 (or higher) with at least 16 GB capacity.
• Set -Xmx value based on available RAM.
• Minimize background processes to free memory.

Adjust View Distance

The render distance, or view distance, is a setting that controls how many chunks load around players. By reducing this value, server strain can be drastically reduced.

Locate the server.properties file. Look for the view-distance setting and change the number to be between 6 and 10 to find a good middle ground of performance and visibility. Set to 6 for your Raspberry Pi servers if you’re running a lot of players.

For single players or small parties, bump it down to 10 for better performance.

Recommended Settings:

• 6 chunks for servers with 3+ players.
• 8-10 chunks for lightweight setups with fewer players.

Optimize Garbage Collection

Memory efficiency is greatly affected by Java garbage collection. Adjusting JVM arguments like -+UseG1GC and tuning parameters such as -XX: MaxGCPauseMillis=50 ensures smoother operations.

Check your GC logs to look for long GC pauses or frequent GCs and tune settings as necessary.

Checklist:

• Add -XX:+UseG1GC to JVM arguments.
• Monitor logs with tools like VisualVM.

Consider Lightweight Plugins

Plugins enhance gameplay but can strain resources. Choose lightweight alternatives such as EssentialsX or Dynmap with limited features.

Upload and enable the plugins through your server’s plugins folder and settings, taking care to configure the plugins to impact performance as little as possible.

Recommended Plugins:

• EssentialsX (basic commands).
• CoreProtect (rollback features).
• LuckPerms (permissions management).

Securing Your Minecraft Server

Though you can focus on aesthetics, never sacrifice security in order to let others enjoy your beautiful creation. Even personal Minecraft servers that host just a few friends are not immune to the risk. Without adequate protections, hacking, data compromise, and server downtime can increase quickly.

Tackle vulnerabilities before they become targets. Protect your participants and create a safe, fun environment for everyone.

Implement a Firewall

A firewall is your first line of defense, working to monitor and control incoming and outgoing network traffic as a means to prevent unauthorized access. Configuring a firewall on your Raspberry Pi is crucial for securing your Minecraft server.

Begin by configuring the built-in firewall, UFW (Uncomplicated Firewall), a firewall that is lightweight and user-friendly. Install it with the command sudo apt install ufw, then enable it using sudo ufw enable.

After that, define strict rules to permit only the traffic you need. As an example, the default port for Minecraft is 25565. To permit this traffic and deny everything else by default, execute the command sudo ufw allow 25565 to do so.

To further enhance security, create a checklist ensuring these settings are optimized:

• Disable unused ports.
• Restrict SSH access to specific IP addresses.
• Regularly review firewall logs for unusual activity.

Manage User Permissions

Regulating who has permission to do what on your server minimizes the risk of damaging actions. Plugins such as LuckPerms can assist you with managing permissions.

You can easily set up detailed roles like “Admin” or “Guest” with fine permissions. For instance, give building permissions only to people you really trust and restrict others to just exploration.

Turn on features that prevent players from breaking blocks or making alterations in critical areas. Consider these permission settings:

• Limit commands like /op to trusted users.
• Whitelist All Players whitelist settings to ensure only players that you add are allowed on the server.
• Regularly review and update permissions to reflect server needs.

Enable Server-Side Encryption

Encryption helps guard player data in transit, further safeguarding against threats to sensitive information. Use easy-to-use tools like “SSL/TLS” to activate encrypted connections.

Set up encryption by creating a self-signed certificate or acquiring a TLS certificate from a recognized certificate authority. Steps include:

• Install OpenSSL with sudo apt install openssl.
• Generate certificates using openssl req -newkey rsa:2048 -nodes -keyout server.key -x509 -days 365 -out server.crt.
• Update your server configuration file to use these certificates.

Automate Server Startup

Automating the server startup process for your Minecraft server on a Raspberry Pi is the next logical step. That way, your server is always ready when you need it!

Automatic startup of servers cuts down on potential downtime, creating more efficiency in server management and saving the headache of getting involved manually. This feature is invaluable to maintaining a constant gaming environment.

It serves another important purpose, too, keeping the server always on and open for SSH or remote access.

Create a Systemd Service

Now, let’s get started creating the systemd service. We’ll set your server up to start on its own, improving performance and your day to day efficiency.

A systemd service eases managing server processes and provides granular control over server startup behavior. To create one:

1. Open the terminal and create a new service file using: sudo nano /etc/systemd/system/minecraft.service.
2. Use the following structure for the service file:

[Unit]Description=Minecraft ServerAfter=network.target

Here’s what that looks like:

[Service]User=piWorkingDirectory=/home/pi/MinecraftServerExecStart=/usr/bin/java -Xmx1024M -Xms1024M -jar server.jar noguiRestart=on-failure

Replacement lines of:

[Install]WantedBy=multi-user.target

This configuration ensures that the server only starts once the network is available. It runs as a systemd service under the correct user and restarts automatically if it crashes.

1. Save and exit the file. Then, reload systemd to recognize the new service: Run sudo systemctl daemon-reload.
2. Enable the service with: sudo systemctl enable minecraft.service.
3. Start the service manually to test: sudo systemctl start minecraft.service.

Checklist for systemd service file

• Correct paths for WorkingDirectory and ExecStart.
• Adequate memory allocation in Java options.
• Restart policy for fault tolerance.

Configure Autostart on Boot

For seamless autostart:

1. Boot to the command line to conserve resources, which is perfect for server performance.
2. Enable the systemd service as described above.
3. To validate autostart, restart the Raspberry Pi and confirm that the server is available at startup.
4. Alternatively, you can use rc.local it to execute scripts at boot, but systemd is more dependable.

You can drastically improve server uptime with zero human intervention. You can improve the performance for 2-3 players strongly, and improve it by a lot with different settings.

Steps for autostart configuration

• Edit the service file for startup behavior.
• Test the service using sudo systemctl status minecraft.service.
• Restart the Raspberry Pi to confirm successful automation.

Troubleshooting Common Issues

Operating your own Minecraft server on a Raspberry Pi can be a fun and educational project, especially when you set up a Spigot server for your Minecraft realms. Familiarizing yourself with common issues like connectivity problems or performance bottlenecks is key to enjoying trouble-free gaming and maximizing the fun factor for all Minecraft players. We've clearly defined these issues and provided steps to troubleshoot, fix, and prevent each.

Diagnose Connection Problems

Networking problems can be a major headache, simply preventing players from connecting to your server. Begin by making sure your Raspberry Pi is connected to the internet. Having a decent internet speed is crucial in being able to host 16 players at a time.

One of the most common reasons is setting up port forwarding incorrectly. Make sure that port 25565 (the default for Minecraft servers) is open on your router. Sites such as Minecraft Server List will check if your server is showing up on their site.

Checking server logs is an important next step. Device logs are invaluable when it comes to displaying error messages that will help you pinpoint various connectivity issues. Search for lines that say things like “Failed to bind to port” or “Player timeout.

These hints might lead you to a solution, like changing your firewall settings or redistributing IP routes. Using a dynamic DNS service such as No-IP makes it much easier for your players to connect by giving them a consistent address to use.

Checklist for Diagnosing Connection Issues:

• Verify stable internet and router configuration.
• Check that port 25565 is forwarded correctly.
• Use the Minecraft Server List to confirm server status.
• Review server logs for error messages.
• Reboot the Raspberry Pi to test automatic startup.

Resolve Performance Bottlenecks

Lag or slow gameplay is usually a symptom of a lack of resources, which leads to performance issues. Start with CPU, RAM, and disk space usage on your Raspberry Pi. Tools such as “htop” can show these metrics live.

Allocating the most RAM possible to the Minecraft server will help performance significantly. As an example, you’ll want to use a Raspberry Pi 4 with at least 4GB of RAM to keep everything running smoothly.

Reduce server availability to create lower expectation settings, such as reducing render distance or removing entities. A 3.0A power supply is essential to avoid hardware throttling that leads to unacceptable performance.

Strategies for Addressing Bottlenecks:

• Monitor resource usage using tools like "htop."
• Allocate more RAM to the server.
• Reduce render distance and limit entities.
• Ensure a 3.0A or better power supply.

Address Server Crashes

Server crashes can be extremely disruptive to everyone’s gameplay and are usually caused by either server-side misconfigurations or sheer workload stress. Review crash reports to help determine the cause.

These files often point out things such as plugin conflicts, unsupported mods, etc. Keeping plugins up to date, or making sure that they are compatible with your specific Minecraft version, can stop crashes for good.

In addition, overheating can potentially cause the server to crash. Don’t block any ventilation holes on the Raspberry Pi or install a cooler Raspberry Pi case with a cooling fan.

It’s a good idea to test your setup by rebooting the Pi to make sure things will start on their own as expected.

Checklist for Preventing Crashes:

• Analyze crash reports for plugin or mod conflicts.
• Update plugins and mods to match your Minecraft version.
• Prevent overheating by using cooling solutions.
• Reboot the Raspberry Pi to test stability.
