Run Shell Script On Boot

[greenlemon]

Alreet folks,

I've had a Pi for a while doing nothing but running XBMC
I recently decided to run it as an internet connected headless music server to run my music via a flash player on any PC.
I've got this working for the most part but not as headless as I wanted, I have the RPi with nothing more than an Edimax WiFi Dongle and a 1TB Ext HDD containing the music. The service I have runs perfectly well but I have to SSH into the Pi to start to run a shell script the run the .jar file to start the service. Trouble is when I ssh into my pi and start the service I get the following.

Code: Select all

pi@raspberrypi ~ $ ./startup.sh
Started admin server on port 9092

I expect this to happen when running it from a command prompt so it makes sense that it does it over SSH. Trouble is I then have a laptop with a ssh terminal open that I can't close or the service stops.

I'm trying to get the file /home/pi/startup.sh to run at bootup. I have the pi setup to boot straight into LXDE.

I must be missing something here but I can't get it to start.

I've added

Code: Select all

@reboot /home/pi/startup.sh

To the crontab file and cron is running.

I'm running an image of Raspbian I downloaded only a few days ago from this site.

Can anybody shed any light on what I might be doing wrong?

Any help much appriciated!

This looks like your script needs some other services to run before being able to start. Try to capture the STDERR that your script might produce or have a look in the syslog file for more cues.

Easy fix: put a delay in that script to give some time for all services to start up (sleep(x) instruction)

More elegant solution: use the init-V hierarchy (run levels) and the init.d scripts (Init Script LSB - Linux Standards Base) to control when your service will be launched. This a more elegant solution because you can determine there when to start and stop your service and at what run level.

Example of an init.d header:

Code: Select all

### BEGIN INIT INFO
# Provides:          skeleton
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Should-Start:      $portmap
# Should-Stop:       $portmap
# X-Start-Before:    nis
# X-Stop-After:      nis
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# X-Interactive:     true
# Short-Description: Example initscript
# Description:       This file should be used to construct scripts to be
#                    placed in /etc/init.d.
### END INIT INFO

You can take any existing init.d script and start modifying it to suit your needs. More info:
