minecraft-server

Some basic tools and stuff to quickly get minecraft running on a linux server

Overview

This repo is to provide a couple of convenient scripts to get a minecraft server running in one place or another. This is useful for an AWS instance of Minecraft as well as a local Docker instance.

Instructions

Platform-specific setup

Docker

Pull down this repo as you'll need it to build your Docker images.

I'm assuming you have Docker installed and running. If not, do that first and get docker-machine started. Then:

docker build -t mitch/mc .

It'll do some magic on a CentOS instance (instead of Ubuntu as this mimics the Amazon Linux AMI more closely), then create a container with that image:

docker run -ti -p 25565:25565 mitch/mc

Or if you want to make some mods before you start it, drop into the bash shell first.

docker run -ti -p 25565:25565 mitch/mc bash

Or for two servers simultaneously:

docker run -ti -p 25565:25565 -p 25566:25566 mitch/mc bash

Or how about if you want the server local on your filesystem so you can fiddle with settings without dropping into the server at all? NOTE: this will make mods to your local filesystem in the same repo directory as you're sitting now...

AWS or other local Linux system

If you're building on AWS, I suggest the t2.small at a minimum. I saw a "server running behind" message the first time I logged in, but not after that. If you want to not risk that, go with a t2.medium.

If using a local Linux image, you're ready to go.

Now pull down this repo.

Run:

./buildMinecraftServer.sh && ./runMinecraftServer.sh

That's it!

Set up services to start on boot

If you want to set up your server to start minecraft automatically on boot, put the following in /etc/rc.d/rc.local:

sudo su - ec2-user -c '/usr/bin/tmux new -s mc1 -d "/home/ec2-user/runMinecraftServer.sh minecraft-server" \; set -t mc1 remain-on-exit on'

Note that you'll want to have tmux installed to get this going: yum install -y tmux

Do that so you can log in if you need to and attach to the session and see the output or otherwise interact with it while it's running: tmux a -t mc1. If you want to run multiple servers, run the build script multiple times after renaming the minecraft-server directory each time, then add multiple lines to rc.local for each directory reference. Make sure to run each of them once before you do that so you can modify the port setting in server.properties for each of the minecraft server directories.

This is a cool way to have the minecraft start automatically when the AWS instance does, and when set up with something like AWS Lambda allows you to easily start those remotely using whatever approach you'd like...

Sync AWS backups to local directory

rsync -avz --progress -e 'ssh -i ~/.ssh/mykey.pem' ec2-user@superawesomeip:/home/ec2-user/backups-minecraft/* .

noip configuration for AWS

To set up the noip configuration for a specific server, run noip -C and follow the prompts to update the configuration.
