mpd start on boot on raspberrypi

[chittu]

I can't start mpd on boot with (on my raspberrypi, ARM)
$this->bbcode_second_pass_code('', 'sudo systemctl enable mpd')
because, mpd is running under some user (may be mpd itself a user? I don't know)
How to start mpd on boot under my user "username1" that has mpd database, playlists, etc.

In the service file you can set under [Service] with User= the account you want to start it with.

@andiling could you please feed me more detail, as a noob it is hard for me edit service file, thank you

Edit /usr/lib/systemd/system/mpd.service and replace User=mpd with the account you want to use. Once done run systemctl daemon-reload that changes are loaded.

NO. Do not edit the distro files.

Use either a copy to /etc/systemd/system or a proper drop-in via /etc/systemd/system/mpd.service.d/myuser.conf

@andiling thank you

the only method I got it working is to edit
$this->bbcode_second_pass_code('', '/usr/lib/systemd/system/mpd.service')
by replacing User=mpd to User=desiredusername

None of the other methods work, A copy of this file (/usr/lib/systemd/system/mpd.service) to
$this->bbcode_second_pass_code('', 'copy to /etc/systemd/system') or dropping the same file as $this->bbcode_second_pass_code('', '/etc/systemd/system/mpd.service.d/myuser.conf')

$this->bbcode_second_pass_code('', 'sudo systemctl enable mpd
results
Created symlink from /etc/systemd/system/default.target.wants/mpd.service to /usr/lib/systemd/system/mpd.service')

but I am surprised to note that if I manually create a file (/etc/systemd/system/default.target.wants/mpd.service) with User=desiredusername and leaving the original (/usr/lib/systemd/system/mpd.service) with User=mpd doesn't work. Both the file (/etc/systemd/system/default.target.wants/mpd.service) and (/usr/lib/systemd/system/mpd.service) should have User=desiredusername

The comment of @WarheadsSE is a valid one I suggested an easy but a bit dirty way.

However, you can copy the file e.g. by $this->bbcode_second_pass_code('', 'cp /usr/lib/systemd/system/mpd.service /usr/lib/systemd/system/mpduser.service') and do your modifications in the mpduser.service file. Accordingly then you should $this->bbcode_second_pass_code('', 'systemctl disable mpd.service
systemctl enable mpduser.service') (if mpd is running just reboot or stop mpd.service and start mpduser.service).
