init,d startup script

[bsergean]

Hello,

Here is an init.d startup script, which works on my Mandriva Linux box but which should work elsewhere too. There is a small HOWTO in the header (service may only be available on RedHat based OS). Maybe tons of such things were already submitted, but just in case 🙂

#!/bin/sh
#
# Startup script for the daap server
#
# chkconfig:2345 98 98
# description: mt-daapd is a DAAP server
#
# processname: mt-daapd
# pidfile: /var/run/mt-daapd.pid
# config:
#
# Written by Benjamin Sergeant: bsergean gmail com
# Quick HOWTO:
# I called this script mt-daapd
# su
# cd /etc/init.d/
# cp /path/to/mt-daapd .
# chmod u+x mt-daapd
# chkconfig mt-daapd
#
# From now on, use
# service mt-daapd start # start
# service mt-daapd stop # stop
# service -f mt-daapd # restart
#
# Have fun !!

# FIXME: When restarting, sometimes mt-daapd exit with 0 but is not launched
# (need to cleanup some stuff, flush some files ??)
# with the sleep no problem. We should investigate the log file
