Mpd4 comes with no log configured in the server so we need to configure the logrotate to support mpd4 log.

Below is the steps how to configure mpd4 log :
Login into your server with root access

Edit Syslog.conf

#pico /etc/syslog.conf

### scroll down until the end of files ###
### add few lines below into syslog.conf ###

!mpd
*.*                /var/log/mpd.log

### save this file

Create log files in /var/log

#touch /var/log/mpd.log
#chmod o-r /var/log/mpd.log
#chgrp network /var/log/mpd.log

Add MPD flag into /etc/rc.conf

mpd_enable=”YES”
mpd_flags=”-b -s mpd”

Restart Syslog & MPD4 Server

#/etc/rc.d/syslogd reload
#/usr/local/etc/rc.d/mpd4 restart

Result in Tail

#tail -f /var/log/mpd.log
