Installation de MPD sur un raspberry pi !
Nous allons voir comment installer MPD (Music Player Daemon) sur le raspberry pi.
MPD (Music Player Daemon) est un lecteur qui utilise une architecture client/serveur, ce qui permet de le contrôler à distance. De nombreux clients sont disponibles. Il reste néanmoins un lecteur de choix pour une machine de bureau, léger et efficace.
Installation du serveur
1. On met à jour la base de packages de raspbian
sudo apt-get update sudo apt-get upgrade
2. On installe les outils nécéssaires :
sudo apt-get install alsa-utils mpg321 lame
3. On vérifie si le module sonore est chargé, si pas on le charge :
sudo modprobe snd-bcm2835
4. On configure la sortie audio : On sélectionne la sortie audio que l'on veut utiliser. Pour cela on modifie le dernier chiffre par ce que l'on veut utiliser (0=auto, 1=analog, 2=HDMI).
sudo amixer cset numid=3 1
5. On installe le serveur mpd :
sudo apt-get install mpd
On change les droits sur le répertoire /var/lib/mpd et /var/rum/mpd
sudo chmod -R g+w,o+w /var/lib/mpd sudo chmod -R g+w /var/run/mpd
6. On édite le fichier de configuration /etc/mpd.conf
# 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 "/var/lib/mpd/music" # # 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" # ############################################################################### ... #bind_to_address "localhost" ...
7. On copie nos musiques sur le raspberry pi dans le répertoire /var/lib/mpd/music
8. On crée un fichier radio.m3u avec les radios que l'on veut pouvoir écouter par internet et on le copie dans /var/lib/mpd/playlists
#EXTM3U #EXTINF:-1,Pure FM http://broadcast.infomaniak.net:80/purefm-128.mp3 #EXTINF:-1,Classic 21 http://broadcast.infomaniak.net:80/classic21-128.mp3 #EXTINF:-1,Vivacité http://broadcast.infomaniak.net:80/vivabxl-128.mp3 #EXTINF:-1,Bel RTL http://audiostream.rtl.be/belrtl128 #EXTINF:-1,Contact FM http://radio-contact.ice.infomaniak.ch:80/radio-contact-high #EXTINF:-1,Nostalgie http://broadcast-adswizz.infomaniak.net:8000/nostalgiepremium-128.mp3 #EXTINF:-1,NRJ http://broadcast.infomaniak.net:80/nrjbe-high.mp3 #EXTINF:-1,Radio Contact http://audiostream.rtl.be/contactfr
Télécharger le fichier radio m3u que l'on veut et copier le contenu dans notre fichier radio.m3u en respectant la syntaxe.
Installation d'un client GTK
On installe un client sur son pc et on peut écouter la musique qui se trouve sur son raspberry pi :
apt-get install gmpc
Installation d'un client web
Nous allons installer un client web sur le serveur MPD. Cela permettra de piloter MPD via un navigateur web.
1. On install un serveur web
apt-get install nginx php-apc php5-fpm
2. On télécharge la dernière version de romprrompr.
3. On décompresse l'archive dans /var/www/
sudo mkdir www cd www sudo wget http://downloads.sourceforge.net/project/rompr/rompr-0.40.zip sudo unzip rompr-0.40.zip && sudo rm rompr-0.40.zip cd ..
4. On applique les bons droits sur le répertoire www et rompr.
chmod -R www-data:www-data www
5. On crée le fichier rompr de config pour nginx dans /etc/nginx/sites-available/.
server {
listen 9191;
root /var/www/rompr;
index index.php;
server_name raspberrypi;
error_log /var/log/nginx/rompr_error.log;
access_log /var/log/nginx/rompr_access.log;
location ~ .php$ {
include /etc/nginx/fastcgi_params;
try_files $uri =404;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass unix:/var/run/php5-fpm.sock;
}
}
6. On active le site.
sudo ln -s /etc/nginx/sites-available/rompr /etc/nginx/sites-enabled/rompr
7. On redémarre nginx.
sudo service nginx restart
8. On se connnecte sur l'application web (adresse_ip_du_raspberrypi:9191).
