A Raspberry Pi can be purchased for as little as $35, making it an incredibly affordable option for anyone looking to host a server. Additionally, the low power consumption of the Raspberry Pi means that it won’t significantly impact your electricity bill.

Another benefit of using a Raspberry Pi is its small size. The compact design of the Raspberry Pi means that it can be easily stored and transported, making it a great option for those who need to host a server on-the-go.

What are the technical specifications of the Raspberry Pi?

The Raspberry Pi comes in a range of models, each with varying specifications. For the purpose of hosting a Minecraft server, we recommend using a Raspberry Pi 4 Model B, which has the following specifications:

Setting up the Raspberry Pi

Now that we’ve gone over the basics of the Raspberry Pi, let’s dive into setting it up for hosting a Minecraft server. Here’s what you’ll need:

• A Raspberry Pi 4 Model B (or another model, but we recommend the 4)
• A microSD card (at least 8GB in size)
• A power supply (at least 5V and 3A)
• An HDMI cable and monitor (optional, but helpful for initial setup)
• A keyboard and mouse (optional, but helpful for initial setup)

Installing Raspbian on the microSD card

The first step in setting up the Raspberry Pi is to install the Raspbian operating system on the microSD card. Here’s how to do it:

1. Download the Raspbian image from the official Raspberry Pi website.
2. Insert the microSD card into your computer and open up a disk image utility.
3. Unzip the Raspbian image and write it to the microSD card using the disk image utility.
4. Eject the microSD card from your computer and insert it into the Raspberry Pi.

Connecting the Raspberry Pi to the internet

Next, we need to connect the Raspberry Pi to the internet so that we can download and install the necessary software. Here’s how to do it:

1. Connect an Ethernet cable from your router to the Ethernet port on the Raspberry Pi.
2. If you’re using a wireless connection, click on the Wi-Fi icon in the top-right corner of the Raspbian desktop and select your network from the list.

Updating the Raspberry Pi

Before we can start installing the software for hosting the Minecraft server, we need to make sure that the Raspberry Pi is up-to-date. Here’s how to update it:

1. Open up a terminal window on the Raspberry Pi by clicking on the terminal icon in the top-left corner of the desktop.
2. Type the following command and press Enter: sudo apt-get update
3. Once the update has finished, type the following command and press Enter: sudo apt-get upgrade
4. Follow the prompts to complete the upgrade process.

Installing the Minecraft server software

Now that the Raspberry Pi is up-to-date, we’re ready to install the Minecraft server software. Here’s how to do it:

Downloading the Minecraft server software

The first step in installing the Minecraft server software is to download it from the official Minecraft website. Here’s how:

1. Open up a web browser on the Raspberry Pi and go to the official Minecraft website.
2. Click on the “Download server software” button.
3. Make sure that you select the correct version of Minecraft for your server (e.g. Minecraft 1.16.5).
4. Click on the download link to start the download process.

Installing Java

The Minecraft server software requires Java in order to run, so we need to install it on the Raspberry Pi. Here’s how:

1. Open up a terminal window on the Raspberry Pi.
2. Type the following command and press Enter: sudo apt-get install default-jre
3. Follow the prompts to complete the installation process.

Running the Minecraft server software

Now that we’ve downloaded the Minecraft server software and installed Java, we’re ready to start the server. Here’s how:

1. Open up a terminal window on the Raspberry Pi.
2. Navigate to the directory where you downloaded the Minecraft server software.
3. Type the following command and press Enter: java -Xmx1024M -Xms1024M -jar minecraft_server.1.16.5.jar nogui

This command will start the Minecraft server with 1GB of RAM allocated to it. If you have a Raspberry Pi with more RAM, you can adjust these numbers accordingly.

Optimizing the Raspberry Pi for Minecraft

Now that we’ve got the Minecraft server up and running on the Raspberry Pi, there are a few things we can do to optimize its performance. Here are some tips:

Allocate more RAM to the server

If you have a Raspberry Pi with more than 1GB of RAM, you can allocate more of it to the Minecraft server. Here’s how:

1. Open up a text editor on the Raspberry Pi.
2. Create a new file and paste the following text into it:

“`#!/bin/shjava -Xmx2048M -Xms2048M -jar minecraft_server.1.16.5.jar nogui“`

3. Save the file as “start.sh” in the same directory as the Minecraft server software.
4. Open up a terminal window and navigate to the directory where the Minecraft server software and start.sh file are located.
5. Type the following command and press Enter: chmod +x start.sh
6. Type the following command and press Enter: ./start.sh

This will start the Minecraft server with 2GB of RAM allocated to it. You can adjust the numbers in the “start.sh” file to allocate more or less RAM as needed.

Disable unnecessary services

By default, Raspbian comes with a number of services enabled that you may not need when running a Minecraft server. Disabling these services can free up resources and improve performance. Here’s how:

1. Open up a terminal window on the Raspberry Pi.
2. Type the following command and press Enter: sudo raspi-config
3. Using the arrow keys, navigate to “Advanced Options” and press Enter.
4. Navigate to “Boot Options” and press Enter.
5. Select “Desktop / CLI” and press Enter.
6. Select “Console” and press Enter.
7. Reboot the Raspberry Pi for the changes to take effect.

Disabling the desktop environment and other unnecessary services can free up resources for the Minecraft server, but keep in mind that it will also make it more difficult to interact with the Raspberry Pi through a graphical interface.

Overclock the Raspberry Pi (optional)

If you’re comfortable with tinkering with the Raspberry Pi’s settings, you can overclock it to improve performance. Keep in mind that overclocking can potentially damage the Raspberry Pi if not done properly, so proceed with caution. Here’s how to do it:

1. Open up a terminal window on the Raspberry Pi.
2. Type the following command and press Enter: sudo nano /boot/config.txt
3. Find the following lines in the file:

“`#uncomment to overclock the arm. 700 MHz is the default.#arm_freq=800“`

4. Uncomment the “arm_freq=800” line by removing the “#” symbol, and change the value to the desired frequency (e.g. “arm_freq=1200” for 1.2GHz).
5. Save the changes and exit the editor.
6. Reboot the Raspberry Pi for the changes to take effect.

Again, keep in mind that overclocking can potentially damage the Raspberry Pi if not done properly.
