problem with mpd starting

[mred]

I'm having trouble getting mpd to automatically start as the router boots. I've done the commandln -s /etc/init.d/mpd /etc/rc.d/S93mpd, but it doesn't seem to have worked. Is there a better way of automating startup of mpd?

[gerben]

Do you mean start MPD, or start music playback?

[mred]

Both really. Specifically I meant to start mpd only, but if I can make it start, and play, that would be great too!

No, there is no better way to automatically start something at boot. Putting a script in /etc/init.d and then linking to it from /etc/rc.d is simply the way this is done.

What does "ls /etc/init.d/ -l" give? What about "ls /etc/rc.d/ -l" ?

I guess there's stuff there I should have stripped out, but not quite knowing, I thought I'd leave it there....

So what's the content of your mpd script in /etc/init.d? Try "cat /etc/init.d/mpd"

Hi Jeroen,

Here are the results of doing that:

root@OpenWrt:~# cat /etc/init.d/mpd
#!/bin/sh /etc/rc.common
# Copyright (C) 2007 OpenWrt.org
START=93

start() {
#create mpd directories
md=`grep music_directory /etc/mpd.conf | cut -d "\"" -f 2 | sed "s/~/\/root/g"`
if [ ! -d $md ]; then
mkdir -p $md
fi
pld=`grep playlist_directory /etc/mpd.conf | cut -d "\"" -f 2 | sed "s/~/\/root/g"`
if [ ! -d $pld ]; then
mkdir -p $pld
fi
#create mpd db
/usr/bin/mpd --stdout --create-db

#optional export for mpc
#export MPD_HOST=127.0.0.1

#start mpd
/usr/bin/mpd
mpd

#generate playlist and start to play
/usr/bin/mpc listall | /usr/bin/mpc add -
/usr/bin/mpc play
/usr/bin/mpc repeat
}

stop() {
killall mpd
}

I am probably just overlooking something, so thankyou very much for your help And a very happy New Year to you and your family too!

[jeroen94704]

Oh, wait, I think I see the problem. The symlink in /etc/rc.d/ does not point to the file "/etc/init.d/mpd", but to a directory "/etc/init.d/mpd/" (notice the trailing slash?). Removing the link in /etc/rc.d and recreating it without the trailing "/" should fix your problem.

[mred]

Jeroen, you are a genius, and I am an idiot! I told you it would be something very simple! Thankyou so much for your help, isn't it amazing how much difference one keystroke can make!
