Minecraft Server Startup Script

A basic startup script for minecraft-server

Prerequisites

• This script has been tested on Amazon Linux AMI but should work on any Red Hat Enterprise Linux (RHEL) compatible distro, eg: CentOS
• You should have minecraft-server installed in WORKDIR (default: /usr/local/minecraft-server)

Installation

1. Simply drop the minecraft-server file into /etc/init.d
2. Adjust the following variables at the top of the file to match your system's capabilities:
   1. WORKDIR - path where minecraft-server is installed
   2. MIN_MEMORY_ALLOCATION - Initial memory allocation pool for JVM
   3. MAX_MEMORY_ALLOCATION - Maximum memory allocation pool for JVM
   4. JAVA_FLAGS - By default this script uses Java flags recommended by Aikar. Adjust as needed for your system.

Usage

• Start Minecraft Server: service minecraft-server start
• Stop Minecraft Server: service minecraft-server stop
• Restart Minecraft Server: service minecraft-server restart
• Get Minecraft Server Status: service minecraft-server status

Notes

• The service will start in the background and ignore the HUP signal.
• stderr/stdout will be routed to $WORKDIR/service.log

Upgrading Minecraft Server

Assuming you already have Minecraft Server installed, you can easily upgrade to a new version like so:

wget https://launcher.mojang.com/mc/game/X.YY.Z/server/abcdefg12345/server.jar -O /usr/local/minecraft-server/minecraft_server.X.YY.Z.jar
chown minecraft-server.daemon /usr/local/minecraft-server/minecraft_server.X.YY.Z.jar
ln -sf /usr/local/minecraft-server/minecraft_server.X.YY.Z.jar server.jar
service minecraft-server restart

Checking Server Logs

sudo tail --lines=500 -f /usr/local/minecraft-server/logs/latest.log

Making Your Server Private

1. Edit /usr/local/minecraft-server/server.properties and set enforcement of whitelist:

   enforce-whitelist=true
   

2. Restart the server: service minecraft-server restart

Adding Users To Your Private Server

1. Find the user's UUID from https://mcuuid.net/
2. Edit /usr/local/minecraft-server/whitelist.json and add them:

   [
     {
       "uuid": "d56f5713-fb33-4b2c-ab22-725cb362542d",
       "name": "SomeUser"
     },
     {
       "uuid": "034b1c1c-4a1c-463b-b70e-1c0c53737efd",
       "name": "AnotherUser"
     },
   ]
