[SOLVED]mpd does not detect the music directory

vlad951 · 2011-05-06 16:48:34

I recently installed mpd with the gmpc gui, set my "music_directory" in /etc/mpd.conf to the location of all of my music (which contains lots of other folders and subfolders), but there's no listing of the audio files in the database in gmpc.

Here's the /etc/mpd.conf if that helps:

# An example configuration file for MPD
# See the mpd.conf man page for a more detailed description of each parameter.


# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This 
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory        "/var/lib/mpd/music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use 
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory "/var/lib/mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the 
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file "/var/lib/mpd/mpd.db"
# 
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, otherwise logging is disabled.
#
log_file "/var/log/mpd/mpd.log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file "/var/run/mpd/mpd.pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server 
# state will be reset on server start up.
#
state_file "/var/lib/mpd/mpdstate"
#
# The location of the sticker database.  This is a database which
# manages dynamic information attached to songs.

# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
user "mpd"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group                "nogroup"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon.
#
# For network

# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
#port                "6600"
#
# This setting controls the type of information which is logged. Available 
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
#log_level            "default"
#
# If you have a problem with your MP3s ending abruptly it is recommended that 
# you set this argument to "no" to attempt to fix the problem. If this solves
# the problem, it is highly recommended to fix the MP3 files with vbrfix
# (available from <http://www.willwap.co.uk/Programs/vbrfix.php>), at which

Three things.

First: Please go back and edit your post and wrap the configuration file in Code Tags It makes things a lot more readable (mono spaced fonts so columns line up, scroll bars, all segregated in an easy to identify text box)

Second: How are you starting mpd (as a user or as a system daemon) ??

Third: Have you checked the permissions on the directory and it's parents to ensure the UID under which mpd is running is allowed read access ??

Fourth: (Okay, I lied) If mpd is configured to log, is there anything interesting in the logs. Try to start the daemon by hand and enable the debug option to see if it coughs up any clues.

vlad951 · 2011-05-06 17:45:15

I start mpd as a system daemon which was set in /etc/rc.conf.
Regarding the permissions of the directories, they are not set to be readable. The problem is that there are about a hundred directories under the music directory that I set, and I can't find an easy way to change the permissions for each one.

Do you have an idea?

ewaller · 2011-05-06 17:55:30

Copy the mpd configuration from /etc to your home directory. Modify the copy to put logs and other temp files in a directory off of your home and start mpd as a user rather than as a system daemon. It will run with your permissions. I auto start it with an an entry in ~/,config/autostart

Or... (be very careful -R means recursive)

chmod -R -o+r /var/lib/mpd

vlad951 · 2011-05-06 18:34:32

Is either way superior to the other?

ewaller · 2011-05-06 21:46:03

I suppose it depends on what you are trying to do. The second should change the permissions on the files so that the system daemon (and everyone) can see them. The only reason (in my mind) to run the system daemon is if you are running a media server in which other devices on the network can cause your system to play music.

The first allows you to run mpd as a user. mpd operation, in this case, is really only usable as a personal music player; of course, that is what you probably want to do anyway.

Larsson · 2011-05-07 06:50:31

mpd will run as user mpd and group users either way, the only thing that changes is the configurationfile it reads. You can start it in the daemon row and it will use /etc/mpd.conf, and it will use ~/.mpdconf if you start mpd as a user.
To solve your problem, have you checked that mpd starts and that gmpc connects to the server. Check /var/log/mpd/mpd.log. Also copy the configuration to your home folder and run mpd in a terminal and se what it spits out.

vlad951 · 2011-05-07 08:06:52

Thanks, I successfully launched mpd as a user and it detected all of my music. However, if I launch mpd with the mpd.conf that I created in my home directory, it launches, but outputs the following:

[vladislav@vladislav .mpd]$ mpd ~/.mpd/mpd.conf 
listen: bind to '0.0.0.0:6600' failed: Address already in use (continuing anyway, because binding to '[::]:6600' succeeded)

Is this normal?

jasonwryan · 2011-05-07 08:09:57

It shouldn't error.

Try

mpd --no-daemon --stdout --verbose

vlad951 · 2011-05-07 08:23:02

Nope, it still errors.

[vladislav@vladislav ~]$ mpd --no-daemon --stdout --verbose
config: loading file /home/vladislav/.mpd/mpd.conf
listen: bind to '0.0.0.0:6600' failed: Address already in use (continuing anyway, because binding to '[::]:6600' succeeded)

Also, another problem. I how do I make mpd to run at startup? I tried using .xinitrc for this purpose, but it doesn't work.

Make sure it is not already running...

ps aux | grep mpd

I have this in my .xinitrc

*sigh* i answer this for the 3rd time in a row... this is no error it just says that binding to your ipv6 interface happened before the binding to ipv4.
If you want to use your ipv4 interface hardcode it in mpd.conf

bind_to_address "127.0.0.1"

you can also have several binds:

bind_to_address "127.0.0.1"
bind_to_address "192.168.1.13"

to make it listen on localhost and the external IP of your network card.

If your music is on the same machine as your mpd i recommend to use a unix socket in addition.

bind_to_address "/path/to/some/file/that/does/not/exist/yet"

and make your client connect to that file instead of the IP. Speeds things up a log e.g. in ncmpcpp

and btw: you can save your mpd.conf file as ~/.mpdconf and mpd will automatically use it.

Thanks everyone for your help! It launches through a script that runs every time the gnome session starts (through gnome-session-properties) because setting it in .xinitrc has failed, and the file doesn't even seem to load at all... either way, it works!
