mpd - Various problems make playing audio impossible.

mikek17 · 2017-03-12 10:27:03

I know that the title of this thread is a little vague, but sorry, it's the best I could do.
That's because I've tried multiple ways to get mpd to run and none of them work.
After properly configuring both mpd and ncmpcpp as described in their respective wiki articles, and enabling and starting mpd via systemd produces the error "config: Found database setting without music_directory - disabling database".
This makes it so when I try to use ncmpcpp and press 'u' to update the database, in the bottom left-hand corner it reads "MPD: no database" despite the fact that the database file specified in the mpd.conf file exists, and I can even access it normally through the filesystem, such as with ls commands.
I found that part the most confusing in this issue.
So after a little bit of google searching I tried a few suggestions and none of them got me anywhere, until I read about using systemd --user enable, rather than just systemd enable.
But whenever I use that, I new problem crops up--when I start ncmpcpp, it says "connection refused" as if mpd were not running at all!
Thanks,
- Mike

Have you setup your music directory, with rw access to mpd?

As a side note: it would be easier to run mpd as user as compared to using global settings.

mikek17 · 2017-03-12 13:38:51

Yes, I have. The problem with the database still occurs.
When I run as a user, as explained, that problem doesn't happen, but instead I cannot access mpd from ncmpcpp.
It says "connection refused".
Does a normal account on Linux require some sort of change to access the proper port?

let us choose one of the options, say running mpd as user
1. have you created .config/mpd/mpd.conf ? If yes post it's contents.
2. stop/disable your systemd service, for mpd
3. simply start "mpd" from your terminal, if there are no errors, start "mpc" or "ncmpcpp" post if there are any errors.

1. yes I have.

# 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		"/home/michael/Documents/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	"/home/michael/.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

# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#

db_file			"/home/michael/.mpd/database"

# 
# 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		"/home/michael/.mpd/log"

#
# This setting sets the location of the file which stores the process ID

#

pid_file		"/home/michael/.mpd/pid"

#
# This setting sets the location of the file which contains information about

2. it is already disabled

3. ncmpcpp says "no active MPD connection" and "connection refused". I have already verified that the address and port in the ~/.ncmpcpp/config file are correct.

change bind to address

 bind_to_address         "127.0.0.1"

or
localhost or 0.0.0.0

look at this link to get help about creating mpd.conf

Nope. Doesn't help. Still get "connection refused". Even if I run mpd from the terminal emulator.
EDIT: Also, I made a config file (after backing up the old one) with the script you linked. I get the same error that I did when originally running mpd as a systemd unit, system wide. That is, the database file exists, but mpd says it doesn't.

Please paste the output of:

and your ncmpcpp conf.
