2. Step-by-Step Guide: Setting Up Your Ubuntu Minecraft Server

Ready to get your Minecraft server up and running on Ubuntu? Follow these steps for a successful setup.

2.1 Installing Ubuntu Server

Before setting up your Minecraft server, you need to install Ubuntu Server on your chosen hardware or virtual machine.

Download Ubuntu Server:
- Visit the official Ubuntu website and download the latest version of Ubuntu Server LTS (Long Term Support).
Create Bootable Media:
- Use a tool like Rufus or Etcher to create a bootable USB drive or DVD with the downloaded ISO image.
Boot from the Media:
- Insert the USB drive or DVD into your server and boot from it. You may need to adjust the boot order in your BIOS settings.
Follow the Installation Prompts:
- Select your language, keyboard layout, and network configuration.
- Create a user account and set a strong password.
- Choose the “Install OpenSSH server” option to enable remote access.
- Select the appropriate storage configuration for your server.
Complete the Installation:
- Once the installation is complete, reboot your server.

2.2 Updating Your Server

After installing Ubuntu Server, the next step is to update the system packages to ensure you have the latest security patches and software updates.

Open a Terminal:
- Log in to your server via SSH or directly from the console.
Update the Package List:
```
sudo apt update
```
Upgrade the Installed Packages:
```
sudo apt upgrade -y
```
Reboot the Server:
- After the upgrade is complete, reboot your server to apply the changes.
```
sudo reboot
```

2.3 Installing Java

Minecraft requires Java to run, so you need to install the Java Development Kit (JDK) on your Ubuntu server.

Add the Java Repository:

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt update

Install the Latest Version of Java (Java 17 or later):
```
sudo apt install openjdk-17-jdk -y
```
Verify the Installation:
```
java -version
```
- This command should display the installed Java version, confirming that Java is properly installed.

2.4 Downloading the Minecraft Server Software

Now that Java is installed, you can download the Minecraft server software from the official Minecraft website.

Create a Directory for the Minecraft Server:
```
sudo mkdir /opt/minecraft
cd /opt/minecraft
```
Download the Minecraft Server JAR File:
```
wget https://piston-data.mojang.com/v1/objects/450698d1863ab5180c25d7c804ef0fe6369dd1ba/server.jar
```
- Make sure to replace the URL with the latest version available on the Minecraft website.
Rename the JAR File (Optional):
```
sudo mv server.jar minecraft_server.jar
```

2.5 Configuring the Minecraft Server

Before starting the Minecraft server, you need to configure it by accepting the EULA (End User License Agreement) and adjusting server settings.

Run the Server Once to Generate the eula.txt File:
```
sudo java -jar minecraft_server.jar --nogui
```
- This will generate the eula.txt file and then stop because you haven’t accepted the EULA yet.
Accept the EULA:
```
sudo nano eula.txt
```
- Change eula=false to eula=true.
- Save the file and exit the text editor.
Configure Server Properties:
```
sudo nano server.properties
```
- Adjust the server settings according to your preferences, such as:
  - level-name: The name of your Minecraft world.
  - server-port: The port your server will listen on (default is 25565).
  - max-players: The maximum number of players allowed on the server.
  - online-mode: Set to true for authentication with Minecraft servers, false for offline mode (not recommended for public servers).
  - motd: The message that appears in the Minecraft server list.
  - Save the file and exit the text editor.

2.6 Running the Minecraft Server

With the server configured, you can now start the Minecraft server.

Create a Startup Script:
```
sudo nano start.sh
```
Add the Following Content:
```
#!/bin/bash
java -Xmx4G -Xms2G -jar minecraft_server.jar --nogui
```
- Adjust the -Xmx (maximum memory) and -Xms (minimum memory) values based on your server’s RAM.
- Save the file and exit the text editor.
Make the Script Executable:
```
sudo chmod +x start.sh
```
Run the Server:
```
sudo ./start.sh
```
- The server will start, and you will see the server log in the terminal.
Run the Server in the Background Using Screen:
```
sudo apt install screen -y
screen -S minecraft
sudo ./start.sh
```
- To detach from the screen session, press Ctrl + A, then D.
- To reattach to the screen session, use screen -r minecraft.

2.7 Setting Up a Systemd Service

To ensure your Minecraft server automatically starts on boot and restarts if it crashes, you can set up a systemd service.

Create a Systemd Service File:

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

Add the Following Content:

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

[Service]
WorkingDirectory=/opt/minecraft
User=root
Group=root

ExecStart=/usr/bin/java -Xmx4G -Xms2G -jar minecraft_server.jar --nogui
Restart=on-failure

[Install]
WantedBy=multi-user.target

Adjust the WorkingDirectory, User, Group, and memory allocation settings as needed.
Save the file and exit the text editor.

Enable and Start the Service:

sudo systemctl enable minecraft.service
sudo systemctl start minecraft.service

Check the Service Status:
```
sudo systemctl status minecraft.service
```
- This command will show the status of the Minecraft server, indicating whether it is running successfully.

2.8 How to Secure your Ubuntu Minecraft Server?

Securing your Ubuntu Minecraft server is crucial to protect it from unauthorized access, cyber threats, and potential griefers. Here are some essential security measures you can implement:

Firewall Configuration:

Enable and configure the Ubuntu firewall (ufw) to allow only necessary traffic.

sudo ufw enable
sudo ufw allow 25565/tcp # Minecraft server port
sudo ufw allow 22/tcp    # SSH port (change if using a different port)
sudo ufw enable

Regular Backups:
- Create regular backups of your Minecraft world and server configuration.
```
sudo tar -czvf backup.tar.gz /opt/minecraft
```
  - Store the backups in a secure location, preferably offsite.
Strong Passwords:
- Use strong, unique passwords for all server accounts, including the Minecraft server administrator account.
Limit Access:
- Restrict access to the server console and configuration files to trusted individuals only.
Monitor Logs:
- Regularly monitor server logs for suspicious activity or unauthorized access attempts.
Keep Software Up-to-Date:
- Ensure your Ubuntu server, Java runtime, and Minecraft server software are always up-to-date with the latest security patches.
Use Whitelisting:
- Enable the whitelist feature in the server.properties file to allow only approved players to join the server.
```
whitelist=true
```
  - Add players to the whitelist using the /whitelist add <playername> command in the server console.

2.9 Optimizing Server Performance

To ensure a smooth and enjoyable Minecraft experience for all players, optimizing server performance is essential. Here are some tips for improving your Ubuntu Minecraft server’s performance:

Allocate Sufficient RAM:
- Allocate enough RAM to the Minecraft server process based on the number of players and the complexity of your server setup.
```
java -Xmx4G -Xms2G -jar minecraft_server.jar --nogui
```
  - Adjust the -Xmx (maximum memory) and -Xms (minimum memory) values according to your server’s resources.
Optimize Server Settings:
- Adjust server settings in the server.properties file to improve performance.
  - view-distance: Reduce the view distance to decrease the amount of data sent to clients.
  - max-tick-time: Increase the maximum tick time to prevent server crashes due to lag.
Use a Fast Storage Device:
- Use an SSD (Solid State Drive) for your Minecraft server’s storage to improve read and write speeds.
Monitor Server Performance:
- Regularly monitor server performance using tools like top, htop, or specialized Minecraft server monitoring plugins.

Optimize Java Garbage Collection:

Configure Java garbage collection settings to minimize pauses and improve overall performance.

java -Xmx4G -Xms2G -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=50 -XX:+DisableExplicitGC -jar minecraft_server.jar --nogui

Limit the Number of Entities:
- Reduce the number of entities (e.g., mobs, items) in the world to decrease server load.
Use Server Optimization Mods/Plugins:
- Consider using server optimization mods or plugins like SpongeForge or Paper to improve performance.
