OS X Minecraft server setup

Preface.

This page will describe how i run my Minecraft servers. All scripts i use will soon be available at my BitBucket repo. I just need to finish up the last few details before releasing my first version ;-)

Some of my inspiration was found at electricmonk.nl and minecraft.gamepedia.com.

The guide to YAMS.

Install Macports.

Installation is neatly described at the Macports install page.

Install tmux.

Use macPorts for the install process. It can be done like this at the time of writing they page.

• sudo port install tmux
• type in your password, and you should get something similar to this:

User with limited privileges.

This way of creating a new user for your Minecraft Server IS complicated... but necessary if you want to run your Minecraft Server as secure as possible.
The login to GUI, makes it possible to run scheduled tasks using OS X launchd / launchctl ;-)

1. Do it like this, but After "append Groups/_minecraft GroupMembership _minecraft"
   execute the ddcl command  passed /Users/_minecraft "YourTemporaryPassword"
2. Exit dscl
3. Stop following the guide when you get to "You might want something like this to prevent the user from showing up in the login dropdown:".
4. Log out of OS X
5. Log in as "_minecraft". Skip everything related to the first userlogin on the GUI.
6. Log out.
7. Log in as your normal user.
8. Continue the user creation from "You might want something like this to prevent the user from showing up in the login dropdown:"
9. STOP completely when you reach "Creating the user home". The rest is covered here after :-)

Finish up by deleting the following obsolete files and folders.

1. cd ../_minecraft/
2. sudo rm -R Desktop Documents Downloads Movies Music Pictures

YAMS...

Action	Terminal command
Change to the new user :	sudo su - _minecraft
Download the sourcecode like this :	curl -kLOs https://bitbucket.org/fmjensen/yams
unzip the scripts :	unzip yams-<version>.zip
Change to the directory containing the scripts :	cd yams-<version>
"Update" your server :	./admin_update_server
READ the output from the script you just ran,	and ACT upon the information ;-)
