[Solved]Trouble with starting mpd service as a user.

I came across this link https://bbs.archlinux.org/viewtopic.php?id=120371 , it is the same issue which I faced. Everytime I run mpd --kill it throws me an error "unable to read pid from file". can someone help me with this?
I'm running

systemctl --user start mpd.service

. Which is failing which led me to the above link.

Re: [Solved]Trouble with starting mpd service as a user.

Post your MPD config as well as the output of

journalctl --user-unit=mpd

, simply from the only error message we have so far, remove the pid line from the config, systemd will take care of keeping track of it even without a pid. Also there are several troubleshooting steps mentioned in that thread, the output of which you haven't provided, post the output of them.

Re: [Solved]Trouble with starting mpd service as a user.

mpd config:

music_directory		"~/Media/Music"

playlist_directory		"~/.mpd/playlists"

db_file			"~/.mpd/database"

log_file			"syslog"

pid_file			"~/.mpd/pid"

bind_to_address		"any"

port				"6600"

auto_update	"yes"

audio_output {
	type		"pulse"
	name		"pulse audio"
}

Re: [Solved]Trouble with starting mpd service as a user.

I uncommented the pid line in config and ran the config file, with

mpd --stderr mpd.conf

I get the following message

exception: Failed to bind to '[::]:6600'
exception: nested: Failed to bind socket: Address already in use

After I run the

mpd --kill

I get

fatal_error: no pid_file specified in the config file

Re: [Solved]Trouble with starting mpd service as a user.

Please put information like this into a single post in the future instead of bumping three times. You are likely already starting MPD somewhere, did you enable the system wide service as well? Disable/Stop that.

If that isn't it use something like ss to find out what is blocking the port, FWIW post

systemctl status mpd

Re: [Solved]Trouble with starting mpd service as a user.

Disabled the systemwide mpd service. That stopped it from using the port. Now started the mpd service with

mpd --stderr mpd.conf

It gave me the following output

exception: Failed to bind to '[::]:6600'
exception: nested: Failed to bind socket: Address already in use

Should I ignore these exceptions? And started the mpd client ncmcpp with

ncmpcpp update

to update the database. It showed me playlist 0 items. What could be the reason? The config for ncmpcpp is as follows

mpd_host = localhost
mpd_port = 6600
mpd_music_dir = ~/Media/Music

Both the dirs match even then it is unable to recognize the files in the directory.

Re: [Solved]Trouble with starting mpd service as a user.

The address usage is "normal" and an IPv4 ./. IPv6 thing, you can ignore that.

Edit, disregard this now
What's the output of "mpc stats"?
