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

right i did the command you suggested and i just came back with an error and refusing to do it.. so i just went on a wim and then did yast > system > System Services (Run level) > minecraft >disable then enable
and its seems to be working but now gives:

linux-pcbl:~ # /etc/init.d/minecraft
/etc/init.d/minecraft: line 14: logs: command not found
/etc/init.d/minecraft: line 30: /etc/init.d/config: No such file or directory
Couldn't load config file, please edit config.example and
rename it to config

it is a symlink :L oddly enough so i think ill just copy the config file into the folder and see what happens unless youve got a differen suggestion?

[Ahtenus]

Yeah, the script doesn't really handle hard links, so you could replace
if [ -L $0 ]
then
source readlink $0 | sed "s:[^/]*$:config:"
else
source echo $0 | sed "s:[^/]*$:config:"
fi
with something like this

source /home/minecraft/minecraft-init/config

[littleclaz]

ill give that a go and paste my result.

[littleclaz]

linux-pcbl:~ # /etc/init.d/minecraft ramdisk world
/etc/init.d/minecraft: line 14: logs: command not found
/home/minecraft/config: line 12: syntax error near unexpected token )' /home/minecraft/config: line 12:craftbukkit and vice versa)'
Couldn't load config file, please edit config.example and
rename it to config

[Ahtenus]

Seem like you have a syntax error in your config file

[littleclaz]

right ive just redone the whole lot. and put the config in the /etc/init.d folder and ive got this error now this is without changing anything in the config:

linux-pcbl:~ # /etc/init.d/minecraft ramdisk world
/etc/init.d/minecraft: line 314: syntax error near unexpected token newline' /etc/init.d/minecraft: line 314: as_user "python $OVPATH/overviewer.py --settings $OVCONFIGPATH/$OVCONFIGNAME $WORLDSTORAGE/$1 $OUTPUTMAP" > '
linux-pcbl:~ #

[Ahtenus]

Humm, that's weird, can't find any syntax errors myself. I guess you could remove everything inside start_overviewer() just to see if that works.

Hi
I just tested the script under opensuse and it's work perfectly.

I installed the package git, screen and java.
This is my command line :

As user

 git clone https://github.com/Ahtenus/minecraft-init.git
 mkdir -p minecraft/worldstorage
 cd minecraft-init
 chmod 755 minecraft
 cp config.exemple config

As root

 ln -s /home/username/minecraft-init/minecraft /etc/init.d/minecraft
 chkconfig --set minecraft on
 service minecraft update

The script download the jar and launch it. It's work perfectly for me under the OpenSuse 12.1

[littleclaz]

Hello Guys!

Right..Sorry for not getting back sooner. but ive been without Power for all of yesterday and the most part of today..

righty...

This is how im doing it.. i think its wrong.. but im more of an Debian person than a OpenSUSE but my server's RAID Array isnt supported by Debian ATM..

nano ./minecraft
paste all of the script into nano
ctrl+o
Ctrl+x
nano ./config
paste and edit the config contents into nano
ctrl+o
ctrl+x
ln minecraft /etc/init.d/minecraft
chmod 755 /etc/init.d/minecraft
chkconfig --set minecraft on
