How to Setup a Minecraft Vanilla 1.19.2 Server (Java 17) on Ubuntu/Debian

The 1.18 to 1.20.4 era of Minecraft relies on Java 17. This guide covers the entire Java 17 lifecycle. For information on other versions, see our Minecraft Java Server Compatibility Guide.

Do not run as root: Always host your Minecraft instance through a restricted user account to protect your VPS files from potential game-layer exploits.

Prerequisites #

• A VPS running Ubuntu or Debian (Available on Premium VPS).
• Sudo access for initial Java installation.
• High-speed SSD/NVMe storage (all VoxiHost nodes use NVMe).

Supported Versions #

This Java 17 guide is fully compatible with:

• 1.20 Era: 1.20.4, 1.20.3, 1.20.2, 1.20.1, 1.20
• 1.19 Era: 1.19.4, 1.19.3, 1.19.2, 1.19.1, 1.19
• 1.18 Era: 1.18.2, 1.18.1, 1.18

Step 1: Install Java 17 #

Keep your system secure by performing a full System Update first. Then, install the required LTS Java 17 package:

sudo apt update
sudo apt install openjdk-17-jre-headless -y

Step 2: Create a Dedicated User #

For security, never run your server as root. If you are new to Linux permissions, check our guide on How to Create and Manage Users on Ubuntu/Debian.

sudo adduser --disabled-password --gecos "" minecraft
sudo su - minecraft
mkdir server && cd server

Step 3: Download Minecraft 1.19.2 #

Looking for a different version? You can find direct Mojang download links for all releases in our Minecraft Server Download Archive.

wget https://piston-data.mojang.com/v1/objects/f69c284232d7c7580bd89a5a4931c3581eae1378/server.jar

Step 4: Accept the EULA #

Run the server once to generate the required configuration files:

java -jar server.jar nogui
sed -i 's/eula=false/eula=true/' eula.txt

Step 5: Create Launch Script #

Pro Tip: Using the Nano Editor
Nano is a beginner-friendly text editor for the terminal. If the nano command is not found, install it using sudo apt install nano -y.

• To Save: Press CTRL + O, then hit ENTER.
• To Exit: Press CTRL + X.

Paste the following (Aikar's Flags optimized for G1GC):

nano start.sh

In the editor, paste:

#!/bin/bash
java -Xmx6G -Xms6G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikar.for.v1.20=false -jar server.jar nogui

Make it executable:

chmod +x start.sh

Step 6: First Launch & Administrator Setup #

Before setting up the automatic background service, you should run the server manually at least once to grant yourself administrator (OP) rights.

1. Start the server manually

Run the launch script you just created:

./start.sh

2. Grant Administrator (OP) rights

Once the server has finished loading (you see the "Done!" message), type your command directly into the console:

op your_minecraft_username

3. Stop the server

To save the world data and prepare for background hosting, type:

stop

This will return you to the normal Linux command line.

Step 7: Configure Systemd Service #

For a professional setup, we use systemd. This ensures your server starts automatically if the VPS reboots and handles crashes gracefully.

Exit the minecraft user back to your root/sudo account:

exit

Create the service file:

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

Paste the following configuration:

[Unit]
Description=VoxiHost Minecraft 1.19 Server
After=network.target

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

[Install]
WantedBy=multi-user.target

Enable and start your server:

sudo systemctl daemon-reload
sudo systemctl enable minecraft
sudo systemctl start minecraft

Managing Your Server #

• Check Status: sudo systemctl status minecraft
• View Logs: sudo journalctl -u minecraft -f
• Stop Server: sudo systemctl stop minecraft

Next Steps: Security & Management #

Now that your server is running, don't forget to:

1. DDoS Protection: All VoxiHost servers include automatic VoxiShield protection. Your server is already being monitored to prevent downtime during attacks.
2. Open the Firewall: Allow traffic on port 25565 by running: sudo ufw allow 25565/tcp. For more details, see our UFW Setup Guide.
3. Transfer Files: Want to upload an existing world? Use SFTP as explained in our FileZilla Tutorial.
4. Hardening & Monitoring: Protect your VPS further by securing SSH and setting up Fail2ban. You can also monitor your system resources using htop.
