Install

Base

• sudo apt-get install php5 php5-cli php5-json php5-mysql apache2 mysql-server mpd alsa-base
• php shell exec has to be eneabled; php.ini: file_uploads = On,post_max_size = 100M,upload_max_filesize = 100M
• configure /etc/mpd.conf (music library and audio autput, mixer_type "software")
• sudo service mpd restart
• let mpd rescan the database. For example: on a client: sudo apt-get install gmpc; run gmpc; connect to mpd; do Server -> Update MPD Database
• Create new mysql database and configure "includes/settings.php". Enter your mpd connection infos and also enter the same "path" like you configured for mpd.
• import dist/votempd.sql in the created mysql database.
• run "php daemon.php -f" and run "php daemon.php -p"
• Let your Apache "/" point to the root folder (the folder with index.html)
• in console run: php daemon.php

settings.php

• $GLOBALS["path"]: absolute path to your music library. Has to be the same like you configured in your mpd.conf. Example: "/home/k3x/music"
• $GLOBALS["pathplaylists"]: relative path to your playlistfolder inside $GLOBALS["path"]. Example: "playlists"
• $GLOBALS["pathuploads"]: relative path to your uploadsfolder inside $GLOBALS["path"]. Example: "uploads"
• $GLOBALS["defaultplaylist"]: name of your default playlist (without ".m3u"). The playlist uses the databasetable "playlistitems" so this playlist hast to be scanned before using the command "php daemon.php -p". Example: "charts_2015"
• $GLOBALS["voteskipcount"]: Integer. If this amount of users voted to skip the song it is skipped. Example: 2

Sample folderstructure for examples in settings.php

/
|-home
  |-k3x
    |-music
      |-playlists
        |-charts_2015.m3u
      |-uploads
      |-ACDC
        |-Back in Black.mp3
      |-Creedence Clearwater Revival
        |-Proud Mary.mp3

In this example a valid entry in the playlist would be: "ACDC/Back in Black.mp3"
