 Posted: Sat Apr 26, 2008 7:29 am Post subject: [SOLVED] Permissions for mpd |
 |
|
Hi,
I've recently moved my /var/ directory to a new partition and seem to have screwed up the permissions on some folders.
At present I can't start mpd due to permission problems on /var/lib/mpd , /var/run/mpd and /var/log/mpd
| Code: |
# /etc/init.d/mpd start
* Starting Music Player Daemon ...
problem opening log file "/var/log/mpd/mpd.log" (config line 9) for writing [ !! ]
* ERROR: mpd failed to start
|
Currently the permissions are...
| Code: |
# ls -l /var/log/ | grep mpd
drwxr-xr-x 2 root root 4096 Apr 25 09:52 mpd
# ls -l /var/lib/ | grep mpd
drwxr-xr-x 4 root root 4096 Apr 25 09:52 mpd
|
..and mpd is being started as used mpd....
| /etc/mpd.conf: |
# A default Gentoo configuration file for MPD
# See the mpd.conf man page for a more detailed description of each parameter.
######################## REQUIRED PATHS ########################
music_directory "/home/neil/music"
playlist_directory "/home/neil/music/playlists"
db_file "/var/lib/mpd/database"
log_file "/var/log/mpd/mpd.log"
error_file "/var/log/mpd/mpd.error.log"
################################################################
######################## OPTIONAL PATHS ########################
#
# If you wish to use mpd --kill to stop MPD, then you must
# specify a file here in which to store MPD's process ID.
#
pid_file "/var/run/mpd/mpd.pid"
#
# If specified, MPD will save its current state (playlist,
# current song, playing/paused, etc.) at exit. This will be
# used to restore the session the next time it is run.
#
state_file "/var/lib/mpd/state"
#
################################################################
######################## DAEMON OPTIONS ########################
#
# If started as root, MPD will drop root privileges and run as
# this user instead. Otherwise, MPD will run as the user it was
# started by. If left unspecified, MPD will not drop root
# privileges at all (not recommended).
#
user "mpd"
#user "neil"
#
# The address and port to listen on.
#
#bind_to_address "localhost"
port "6600"
#
# Controls the amount of information that is logged. Can be
# "default", "secure", or "verbose".
#
log_level "default"
#
################################################################
########################## PERMISSIONS #########################
#
# MPD can require that users specify a password before using it.
# You may specify one ore more here, along with what users who
# log in with that password are allowed to do.
#
#password "password@read,add,control,admin"
#
# Specifies what permissions a user who has not logged in with a
# password has. By default, all users have full access to MPD
# if no password is specified above, or no access if one or
# more passwords are specified.
#
#default_permissions "read,add,control,admin"
#
################################################################
########################## AUDIO OUTPUT ########################
#
# MPD supports many audio output types, as well as playing
# through multiple audio outputs at the same time. You can
# specify one or more here. If you don't specify any, MPD will
# automatically scan for a usable audio output.
#
# See <http://mpd.wikia.com/wiki/Configuration#Audio_Outputs>
# for examples of other audio outputs.
#
# An example of an ALSA output:
#
audio_output {
type "alsa"
name "My ALSA Device"
device "hw:0,0" # optional
format "44100:16:2" # optional
}
#
# An example of an OSS output:
#
#audio_output {
# type "oss"
# name "My OSS Device"
# device "/dev/dsp" # optional
# format "44100:16:2" # optional
#}
#
# An example of a shout output (for streaming to Icecast):
#
audio_output {
type "shout"
name "Roller Disco"
host "localhost"
port "8000"
mount "/muzik"
password "password"
# quality "7.0"
bitrate "128"
format "44100:16:1"
user "source" # optional
description "Sounds from the vault of 6 Manor Oaks Drive" # optional
genre "Whatever takes my fancy" # optional
public "no" # optional
}
#
# Force all decoded audio to be converted to this format before
# being passed to the audio outputs.
#
#audio_output_format "44100:16:2"
#
################################################################
############################# MIXER ############################
#
# MPD needs to know what mixer settings to change when you
# adjust the volume. If you don't specify one here, MPD will
# pick one based on which ones it was compiled with support for.
#
# An example for controlling an ALSA mixer:
#
#mixer_type "alsa"
#mixer_device "default"
#mixer_control "PCM"
#
# An example for controlling an OSS mixer:
#
#mixer_type "oss"
#mixer_device "/dev/mixer"
#mixer_control "PCM"
#
# If you want MPD to adjust the volume of audio sent to the
# audio outputs, you can tell it to use the software mixer:
#
#mixer_type "software"
#
################################################################
######################### NORMALIZATION ########################
#
# Specifies the type of ReplayGain to use. Can be "album" or
# "track". ReplayGain will not be used if not specified. See
# <http://www.replaygain.org> for more details.
#
#replaygain "album"
#
# Sets the pre-amp used for files that have ReplayGain tags.
#
#replaygain_preamp "0"
#
# Enable on the fly volume normalization. This will cause the
# volume of all songs played to be adjusted so that they sound
# as though they are of equal loudness.
#
#volume_normalization "no"
#
################################################################
########################### BUFFERING ##########################
#
# The size of the buffer containing decoded audio. You probably
# shouldn't change this.
#
#audio_buffer_size "2048"
#
# How much of the buffer to fill before beginning to play.
#
#buffer_before_play "0%"
#
# Similar options for the HTTP stream buffer. If you hear
# skipping while playing HTTP streams, you may wish to increase
# these.
#
#http_buffer_size "128"
#http_prebuffer_size "25%"
#
################################################################
########################### HTTP PROXY #########################
#
# Specifies the HTTP proxy to use for playing HTTP streams.
#
#http_proxy_host "proxy.isp.com"
#http_proxy_port "8080"
#http_proxy_user "user"
#http_proxy_password "password"
#
################################################################
############################# LIMITS ###########################
#
# These are various limits to prevent MPD from using too many
# resources. You should only change them if they start
# restricting your usage of MPD.
#
#connection_timeout "60"
max_connections "5"
#max_playlist_length "16384"
#max_command_list_size "2048"
#max_output_buffer_size "8192"
#
################################################################
###################### CHARACTER ENCODINGS #####################
#
# If file or directory names do not display correctly, then you
# may need to change this. In most cases it should be either
# "ISO-8859-1" or "UTF-8". You must recreate your database
# after changing this (use mpd --create-db).
#
filesystem_charset "UTF-8"
#
# The encoding that ID3v1 tags should be converted from.
#
#id3v1_encoding "ISO-8859-1"
#
################################################################
######################### OTHER OPTIONS ########################
#
# The metadata types MPD will recognize.
#
#metadata_to_use "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# Enable this if you wish to use your MPD created playlists in
# other music players.
#
#save_absolute_paths_in_playlists "no"
#
################################################################

I've tried changing the permissions to root:mpd on the directories, but am simply told that its an invalid group...
| Code: |
# chown -R root:mpd /var/log/mpd
chown: invalid group: `root:mpd'
# grep mpd /etc/group
#
|
Any idea how to recover from this would be appreciated.
