How to Use Vultr's Minecraft Marketplace Application

Minecraft is a popular sandbox video game that allows players to build, explore, and survive in procedurally generated worlds. The Vultr Minecraft (Vanilla) Marketplace Application deploys a ready-to-use vanilla Minecraft Java Edition server on Ubuntu, including Java runtime, systemd-based service management, and screen session access for real-time console interaction.

This guide explains deploying and using Vultr's Minecraft (Vanilla) Marketplace Application. You will deploy a server, verify the installation, configure firewall security, customize server settings, manage players with whitelists and operators, optimize performance, set up backups, and troubleshoot common issues.

Deploy Vultr's Minecraft (Vanilla) Marketplace Application

1. Log in to your Vultr Console and click the Deploy Server button.

2. Select your preferred server type.

3. Choose a server location.

4. Select a server plan based on expected player count:

   • 1GB RAM, 1 CPU: 1-5 players (testing/small groups)
   • 2GB RAM, 2 CPU: 5-10 players (recommended minimum)
   • 4GB RAM, 2 CPU: 10-20 players
   • 8GB RAM, 4 CPU: 20+ players (large communities)

5. Click the Configure button to proceed.

6. Under Marketplace Apps, search for Minecraft (Vanilla) and select it as the Marketplace Application.

7. Select the Limited Login option from the Additional Features section to create a limited user with sudo access.

8. Review your configurations and click the Deploy Now button to start deployment.

   Note

   It may take up to 10 minutes for your server to finish installing Minecraft and Java.

9. After the instance shows the status of Running, navigate to the Server Overview page and copy the SSH connection details.

Initial Setup and Configuration

After deployment, verify the installation, configure a memorable server address, and secure your Minecraft server before allowing players to connect.

1. Create a DNS A record pointing to your server's IP address, such as mc.example.com. This provides a memorable address for players.

2. Connect to your Vultr server instance over SSH using the connection details from the Server Overview page.

   Save and close the file.

4. Start the Minecraft server.

   CONSOLE

   Copy

   $ sudo systemctl start minecraft.service

   Explain Code

   Powered by Vultr AgentBeta

Manage Players

Control who can access your server and assign administrative privileges using whitelists and operators.

Enable Whitelist

1. Edit the server properties to enable whitelist.

   CONSOLE

   Copy

   $ sudo nano /home/minecraft/server.properties

   Explain Code

   Powered by Vultr AgentBeta
   INI

   Explain Code

   Powered by Vultr AgentBeta

   Save, close, and restart the server.

2. Add players via the server console (see "Access Server Console" section):

   whitelist add PlayerName
   whitelist remove PlayerName
   whitelist reload

Whitelist settings are stored in /home/minecraft/whitelist.json.

Manage Server Operators

Operators (OPs) have administrative privileges on the server.

1. Add a player as an operator (in server console):

   op PlayerName

2. Remove operator status:

   deop PlayerName

3. Ban and pardon players:

   ban PlayerName Reason for ban
   pardon PlayerName

Access Server Console

Interact with the running Minecraft server in real-time using the screen session.

1. Attach to the screen session running Minecraft.

   CONSOLE

   Copy

   $ sudo screen -r

   Explain Code

   Powered by Vultr AgentBeta

2. Run commands in the console:

   list
   say Welcome to the server!

   Copy

   $ sudo nano /home/minecraft/minecraft_server.sh

   Explain Code

   Powered by Vultr AgentBeta

2. Update memory allocation based on your server's RAM (example for 4GB RAM server):

   BASH

   Copy

   #!/bin/bash
   cd /home/minecraft
   java -Xms2G -Xmx3G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -jar server.jar nogui

   Explain Code

   Powered by Vultr AgentBeta

   Key JVM flags:

   • -Xms: Initial heap size
   • -Xmx: Maximum heap size (allocate 50-75% of total RAM)
   • -XX:+UseG1GC: Use G1 garbage collector (recommended for Minecraft)

   For servers with different RAM, adjust -Xms and -Xmx proportionally. Save and close the file.
