Hello there.
Im having some issues with getting the script to work on OpenSUSE 12.1. ive followed the instructions to the letter... Im having a problem getting the script to activate and when it does it gives me a permission denied even under root.. here is the output of my ssh:
linux-pcbl:/home/minecraft # ln -s minecraft /etc/init.d/
linux-pcbl:/home/minecraft # chkconfig --set minecraft on
minecraft: unknown service
linux-pcbl:/home/minecraft # insserv minecraft
insserv: minecraft: Too many levels of symbolic links
linux-pcbl:/home/minecraft #
and also:
linux-pcbl:/home/minecraft # ln /home/minecraft/minecraft /etc/init.d/minecraft
linux-pcbl:/home/minecraft # chkconfig --set minecraft on
insserv: script minecraft is not an executable regular file, skipped!
insserv: Service network is missed in the runlevels 2 to use service webmin
linux-pcbl:/home/minecraft # /etc/init.d/minecraft start
-bash: /etc/init.d/minecraft: Permission denied
I cannot understand whats going on to be honest.. im not really a noob when it comes to linux or opensuse to that fact as the last start script i used from this one:
!/bin/bash
/etc/init.d/minecraft

### SETTINGS
Name of server.jar file
SERVICE="craftbukkit-1.0.1-R1.jar"
Name to use for the screen instance
SCREEN="minecraft"
User that should run the server
USERNAME="minecraft"
Path to minecraft directory
MCPATH="/home/${USERNAME}/Server"
Number of CPUs/cores to use
CPU_COUNT=4
Initial memory usage
INITMEM="2048M"
Maximum amount of memory to use

Remember: give the ramdisk enough space, subtract from the total amount
of RAM available the size of your map and the RAM-consumption of your base system.

Where the world backups should go
BACKUPPATH="/home/${USERNAME}/minebak"
Where the logs are copied with log-roll
LOGPATH="${MCPATH}/logs"
Where the whole minecraft directory is copied when whole-backup is executed
WHOLEBACKUP="/home/${USERNAME}/serverbak"
Where the worlds are located on the disk. Can not be the same as MCPATH.
WORLDSTORAGE="${MCPATH}/worldstorage"
Path to the the mounted ramdisk default in Ubuntu: /dev/shm
