MPD woes - port 6600

Grimnir512 · 2009-10-31 16:08:34

I've seen many posts here on this, but I haven't been able to find a solution.

When I run "mpd --create-db" I get the error:

listen: Failed to listen on *:6600: Address already in use
Aborted

I've tried running it over a different port and still get the same error for the port I try. I'm attempting to run it as my own user and the configuration I have definitely works on Ubuntu.

This is my /etc/mpd.conf, and I have an identical copy stored as .mpdconf in ~.

########################## AUDIO OUTPUT ########################

# for examples of other audio outputs.

Any thoughts as to what might be going on?

You are probably already running mpd. When running mpd again, it would try to bind itself to port 6600, but wil fail since there is already an application (your first mpd) listening to 6600.

Try killing all instances of mpd and create the database:

killall mpd
mpd --create-db

That's it working now Thanks!

just to add a little information here, as i've seen at least three of these posts. mpd's usage has changed.

the old way:

'mpd' would start the deamon, 'mpd --kill' would stop the daemon, 'mpd --create-db' would only create the db and could be used if mpd was already running

the new way:

'mpd' starts the daemon, 'mpd --kill' stops the daemon, 'mpd --create-db' would start mpd and create the db, so it fails if mpd is already bound to that port.

the even newer way (mpd-git):

create-db is no longer a valid option, just use 'mpd' the start the daemon, then use your client ('mpc update' or 'u' in ncmpc) to update/create your db. eventually mpd will use inotify to moniter your music directory anyway and automagically update itself.

hope this clarifies some things. i believe our wiki still assumes the old way (thus the common posts about the bound port error). i keep meaning to change it...

Thanks for the info. I'm sure I used "the new way" on Ubuntu so I don't know why I didn't try it.

Is mpd-git any better than mpd? I tried installing it at one point to see if I still got the same errors and couldn't get it to work at all for the reasons explained in your post
