Minecraft Immie Pi

Minecraft Immie Pi is our tiny home minecraft server running on the Pi.

System and server

• Running on Raspberry Pi, with 512MB RAM.
• For now, running on Zotac ID-42, xbmcbuntu, with 4096MB RAM.

• Using Raspbian image 2014-06-20. Java pre-installed:

$ java -version
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) Client VM (build 24.0-b56, mixed mode)

• Server Spigot 1.7.10

wget http://ci.md-5.net/job/Spigot/lastStableBuild/artifact/Spigot-Server/target/spigot.jar
sudo java -Xms256M -Xmx496M -XX:MaxPermSize=128M -jar /home/pi/mc/spigot.jar nogui

• Now, running Cauldron + Forge server 1.7.2 1.1147.04.107 (to run Mo'Creatures mo)

wget http://adf.ly/901609/http://files.minecraftforge.net/maven/net/minecraftforge/cauldron/1.7.2-1.1147.04.107/cauldron-1.7.2-1.1147.04.107-installer.jar

• Make sure to remove the binding dynamic-complete-history in the .inputrc file, or this will trigger the following error at launch:

SEVERE: Failed to start the minecraft server
java.lang.IllegalArgumentException: No enum constant org.bukkit.craftbukkit.libs.jline.console.Operation.DYNAMIC_COMPLETE_HISTORY
	at java.lang.Enum.valueOf(Enum.java:236)

• Set crontab script to start spigot server automatically at boot.

crontab -l:

# Crontab
#
# Install this crontab with
#
#   sed -r '/^#/!s/\$USER/'$USER'/g' crontab-minecraft | crontab
#
#   !!! THIS WILL OVERWRITE ANY CURRENT CRONTAB !!!
#
# Or append only job to current crontab
#
#   ( crontab -l; sed -r '$!d;s/\$USER/'$USER'/g' crontab-minecraft ) | crontab
#
# Use /bin/bash to run commands, instead of the default /bin/sh
SHELL=/bin/bash
# Define variable USER because we need it in our job scripts
USER=mc
# Mail any output to '$USER', no matter whose crontab this is
MAILTO=mc
# Set PATH - by default it is set to /usr/bin:/bin
PATH=/home/mc/bin:/usr/local/bin:/usr/bin:/bin
#
#
# m h dom mon dow   command     (dow=0|7 is sunday)
