📘 Minecraft Server Control – Commands & Admin Guide (LXC/VM)

This guide contains useful commands to manage a Minecraft server (Java or Bedrock Edition) installed via Proxmox LXC container or VM.

📂 Directory Structure

cd /opt/minecraft         # Java Edition
cd /opt/minecraft-bedrock # Bedrock Edition

▶️ Starting the Server

cd /opt/minecraft
./start.sh

To run in the background via screen:

cd /opt/minecraft
screen -S minecraft ./start.sh

Reconnect to the session:

screen -r minecraft

Detach without stopping the server:

CTRL + A, then D

🔁 Stopping the Server (from Terminal)

In the screen session with the server running:

stop

This cleanly shuts down the server.

📦 Updating the Java (PaperMC) Server

cd /opt/minecraft
./update.sh

Downloads the latest PaperMC version and replaces server.jar.

❗ Bedrock Edition Notice

Bedrock cannot be updated automatically. Instead, run:

cd /opt/minecraft-bedrock
./bedrock_helper.sh

This script shows the manual download link.

⚙️ Advanced Options

Adjusting RAM Allocation (Java)

Edit the start.sh file:

nano /opt/minecraft/start.sh

Example modification:

java -Xms4G -Xmx6G -jar server.jar nogui

🧼 Log Files

cd /opt/minecraft/logs/

🧠 Useful In-Game Admin Commands

If you're listed as OP (ops.json):

/gamemode creative
/give @p minecraft:diamond 64
/ban <playername>

✅ Grant OP Status (via Console or In-Game)

op <playername>

Example:

op TimInTech

📜 Frequently Used Commands
