Nuclear Option: Democratic Server Restart for Minecraft
Server lag is a familiar enemy for anyone running a modded Minecraft world. Memory leaks, entity overload, or simply a long uptime can drag TPS down, leaving players frustrated in chat. The usual fix is a restart, but that requires an admin to be awake and available. Nuclear Option: Democratic Server Restart for Minecraft solves this by putting the power to initiate a controlled shutdown directly into the hands of the community.
How the Democratic Voting System Works
The concept is straightforward. Any player can type /nuke in chat to start a vote. The mod then counts "yes" votes in real time. If more than 50% of the currently connected players agree, a one-minute warning timer begins. Everyone on the server sees the alert on their screen, and when the timer hits zero, the server performs a graceful shutdown.
It is important to note that this mod stops the server; it does not automatically reboot it. The developer has stated that a safe internal restart method for Forge mods is not feasible. Therefore, you must configure an external script, such as a while loop in a startup batch file or a systemd service, to bring the server back online after the process exits. This setup allows players to vote for a restart without needing to contact the owner, ensuring a controlled stop and a predictable return to gameplay.
Key Features of the Latest Update
The most recent version of the mod addresses two significant issues. The first was a bug that caused "democracy leakage": if a player voted and then disconnected immediately, their vote could remain in the system, skewing the quorum count. Votes are now correctly voided when a player leaves. The second fix involved the welcome message, which sometimes failed to display in certain configurations. While this message is optional, the voting fix is critical for fair elections. If you do not use the welcome feature, you can simply leave the config line empty.
Installation and Version Compatibility
Nuclear Option is a serverside-only mod. This means you install it exclusively in the /mods folder of your Minecraft server. No client-side installation is required, so players can join with a standard vanilla or modded client and immediately see the /nuke command. The mod is built with Scala and is designed to be lightweight, reducing the risk of conflicts with other server-side additions.
The mod is designed for the Forge loader. Always verify that the mod version you download matches your server's specific Minecraft version and Forge build to ensure stability. For those using modern launchers, adding this mod is often a matter of a few clicks in the mod management menu, which automatically places files in the correct directories. This approach minimizes manual configuration errors, especially when managing multiple server mods.
Benefits for Server Owners and Players
- Community Autonomy: Players decide when the server needs a break, without waiting for the owner.
- Full Transparency: Vote percentages and the countdown timer are visible to everyone, preventing secret shutdowns.
- Abuse Protection: A majority of the current online player count is required, so a single user cannot trigger a shutdown.
- Minimal Footprint: The code is compact, lowering the chance of mod conflicts and simplifying audits.
- Server-Side Only: No extra downloads or performance hits for the clients.
Setting Up the Restart Script
Because the mod only stops the JVM process, you need a wrapper to catch the exit and start the server again. A basic Linux start.sh script with a loop is a common solution:
#!/bin/bash
while true; do
java -Xmx4G -jar forge-server.jar nogui
echo "Server stopped. Restarting in 5 seconds..."
sleep 5
done
On Windows, you can create an equivalent loop in a .bat file. Ensure the script has execute permissions and that the server starts successfully after a stop. Many hosting panels include an automatic restart feature, in which case Nuclear Option simply triggers a standard shutdown and the panel handles the rest.
Conclusion
