5. MPD 설정 수정하기
본격적으로 수정하기 전에
MC에서 USB사운드카드를 어떤 번호로 인식하는지 알아야 합니다.
aplay -l
위 명령어로 알 수 있습니다.
WDMyCloud:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: Set [USB Headphone Set], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
WDMyCloud:~#
여기서 중요한 것은 빨간 숫자 2개입니다.
지금 보면 1 다음에 0입니다. 이걸 꼭 기억해야 합니다.
nano /etc/mpd.conf
위 명령어로 설정으로 들어갑니다.
# An example configuration file for MPD
# See the mpd.conf man page for a more detailed description of each parameter.
# 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 "/shares"
#
# 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 "/var/lib/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
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file "/var/lib/mpd/tag_cache"
#
# 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 "/var/log/mpd/mpd.log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file "/var/run/mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server
# state will be reset on server start up.
#
state_file "/var/lib/mpd/state"
#
# The location of the sticker database. This is a database which
# manages dynamic information attached to songs.
#
sticker_file "/var/lib/mpd/sticker.sql"
#
###############################################################################
# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
user "mpd"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group "nogroup"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon. Choose any if you want
# to have mpd listen on every address
#
# For network
bind_to_address "0.0.0.0"
#
# And for Unix Socket
#bind_to_address "/var/run/mpd/socket"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
#port "6600"
#
# This setting controls the type of information which is logged. Available
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
#log_level "default"
#
# If you have a problem with your MP3s ending abruptly it is recommended that
# you set this argument to "no" to attempt to fix the problem. If this solves
# the problem, it is highly recommended to fix the MP3 files with vbrfix
# (available as vbrfix in the debian archive), at which
# point gapless MP3 playback can be enabled.
#
#gapless_mp3_playback "yes"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
#save_absolute_paths_in_playlists "no"
#
# This setting defines a list of tag types that will be extracted during the
# audio file discovery process. Optionally, 'comment' can be added to this
# list.
#
#metadata_to_use "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This setting enables automatic update of MPD's database when files in
# music_directory are changed.
#
#auto_update "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself. There is no limit by default.
#
#auto_update_depth "3"
#
###############################################################################
# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links outside of the configured music_directory.
#
#follow_outside_symlinks "yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.
#
#follow_inside_symlinks "yes"
#
###############################################################################
# Zeroconf / Avahi Service Discovery ##########################################
#
# If this setting is set to "yes", service information will be published with
# Zeroconf / Avahi.
#
#zeroconf_enabled "yes"
#
# The argument to this setting will be the Zeroconf / Avahi unique name for
# this MPD server on the network.
#
#zeroconf_name "Music Player"
#
###############################################################################
# Permissions #################################################################
#
# If this setting is set, MPD will require password authorization. The password
# can setting can be specified multiple times for different password profiles.
#
#password "password@read,add,control,admin"
#
# This setting specifies the permissions a user has who has not yet logged in.
#
#default_permissions "read,add,control,admin"
#
###############################################################################
# Input #######################################################################
#
input {
plugin "curl"
# proxy "proxy.isp.com:8080"
# proxy_user "user"
# proxy_password "password"
}
#
###############################################################################
# Audio Output ################################################################
#
# MPD supports various audio output types, as well as playing through multiple
# audio outputs at the same time, through multiple audio_output settings
# blocks. Setting this block is optional, though the server will only attempt
# autodetection for one sound card.
#
# See for examples of
# other audio outputs.
#
# An example of an ALSA output:
#
audio_output {
type "alsa"
name "My Cloud"
device "hw:0,0" # optional 여기가 가장 중요합니다.
format "*:16:*" # optional
# mixer_device "default" # optional
# mixer_control "PCM" # optional
# mixer_index "0" # optional
mixer_type "software"
}
위의 빨간 글자들을 주의해서 수정합니다.
아까 봤던 1 다음에 0은
device "hw:1,0" # optional
위 옵션에 들어갑니다.
기본은 0,0인데, 1 다음에 0이 왔다면 위와 같이 1,0으로 바꿔야 MPD에서 소리가 납니다.
/etc/init.d/mpd start
위 명령어로 mpd를 시작합니다.
6. mpc 설치하기
MPC는 음악을 플레이하는 프로그램이라 보면 됩니다.
apt-get install mpc
위 명령어로 설치합니다.

위 명령어로 리스트 업데이트를 진행합니다.

위와 같이 위와 같이 DB를 업데이트할 수 있습니다.
ncmpc 사용 방법은 콤타강좌를 참조하세요.
위 링크의 중간부터 보시면 됩니다.
8. 윈도우 프로그램 및 안드로이드 앱 소개
외부에서 접속하려면 6600포트를 포트포워딩 하면 됩니다.
DDNS 및 포트포워딩만 된다면 전세계 어디서든 마이클라우드의 음악을 제어할 수 있습니다.
위에 소개되어 있는 프로그램 말고도 칸타타 라는 것도 좋네요. ㅎㅎ
https://code.google.com/p/cantata/downloads/list
위 링크에서 제일 위에 있는 Setup.exe 파일을 받아서 설치합니다. (2014/02/04 현재 Cantata-1.2.2-Setup.exe)
위와 같이 설치 후 사용하면 됩니다.
9. 태그 관리 방법
태그 관리 방법에 있는 파이선 테스트해봤습니다.
apt-get install python
위 명령어로 파이선을 설치합니다.

위 명령어로 클라이언트가 설치될 폴더로 이동합니다.
wget http://client175.googlecode.com/files/client175_0.7.tar.gz
위 명령어로 클라이언트를 다운 받습니다.

위와 같이 받아집니다.
tar xvfz client175_0.7.tar.gz
위 명령어로 압축을 풉니다.
rm -rf client175_0.7.tar.gz
위 명령어로 압축파일을 제거합니다.
chmod -R 755 /DataVolume/client175
위 명령어로 권한을 줍니다.
nohup python /DataVolume/client175/server.py &
위 명령어로 파이선 작동이 계속 됩니다.
엔터를 치면 명령줄로 다시 내려옵니다.
재부팅하거나 끄면 파이선이 정지됩니다.
이제 인터넷 브라우저에서
http://내부IP:8080 을 입력하면
위와 같이 원격제어 가능합니다.
DDNS와 포트포워딩(외부포트8080) 설정하면 외부에서도 접속 가능하겠죠 ㅎㅎ
10. CPU 점유율
위와 같이 대략 15~25% 정도 점유합니다.
상당히 안정적으로 운용이 되네요. ㅎㅎ
이상 MPD 설치 강좌를 마치겠습니다.
