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.

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.
