🔁 Server Restart Command

A simple server-side Fabric mod that lets Minecraft server owners restart their server from in-game or from the server console.

No client install needed. Players do not need this mod.

✅ What does it do?

Minecraft servers normally cannot start themselves again after they stop.

This mod fixes that by starting a small Java relauncher before the server shuts down.

The relauncher waits for the old server process to fully close, then starts the server again.

Simple. Clean. Useful.

🧠 How restarting works

When you run the restart command, the mod tries to restart the server in this order:

1. Uses start.bat on Windows or start.sh on macOS/Linux, if the file exists.
2. Uses launchCommand from the config file, if it is set.
3. Uses a safe fallback command:

java -Xmx4G -jar fabric-server-launch.jar nogui

⚠️ Fallback RAM warning

If the mod has to use the fallback 4 GB RAM command, it will warn operators after the server starts again.

This warning means the owner should set the real launch command in the config file for better restart behavior.

💬 Commands

/restart
/restartserver
/restart <delay_seconds>
/restartserver <delay_seconds>

⏱️ Example

/restart 60

This restarts the server after 60 seconds.

📦 Requirements

• Minecraft 26.1, 26.1.1, 26.1.2, or 26.2

📝 Important notes

• This mod is server-side only.
• Players do not need to install it.
• This does not reload the server.
• This means it is not the same as reloading datapacks.
• It fully stops the server, then starts it again.
• Operators can use the restart command by default.
• For best results, use a proper start.bat, start.sh, or launchCommand.

🧱 Made for server owners who want one simple thing

Restart the server without touching the server window every time.
