Install

Base

  • mpd/php daemon needs reading rights to files
  • upload folder has to be writeable for php daemon
  • sudo apt-get install php7.0 php7.0-cli php7.0-json php7.0-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" (copy from dist/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" (this command does NOT delete old database enties. On rescan truncate files,folders,playlistitems,playlog,voteforskip,votes,options_date,options_int)
  • Let your Apache "/" point to the root folder (the folder with index.html)
  • in console run: php daemon.php

RESCAN

  • copy files
  • Server -> Update MPD Database
  • sudo service mpd stop
  • sudo killall php
  • mysql -u root -p
  • show database;
  • use votempd;
  • show tables;
  • TRUNCATE files;
  • TRUNCATE folders;
  • TRUNCATE playlistitems;
  • TRUNCATE playlog;
  • TRUNCATE voteforskip;
  • TRUNCATE votes;
  • TRUNCATE options_date;
  • TRUNCATE options_int;
  • (CTRL-D)
  • php daemon.php -f
  • php daemon.php -p
  • sudo service mpd start
  • 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"

Language

  • Errors are always in english
  • If you want the interface to be english instead of german: ** Delete index.html and rename index_en.html to index.html. ** in script.js.php, line 26: $language = "en";

Further information / find errors

  • if you configured mpd to use alsa and you can not hear music check "alsamixer". Also check that no channel is muted.
  • ncmpc is a commandline mpd client
  • for uploading files your folder has to be writeable

Autostart

  • if you want the daemon to start on every boot maybe the systemd script dist/votempd.service will help you.
  • sudo nano /etc/systemd/system/votempd.service
  • sudo systemctl daemon-reload
  • sudo systemctl start votempd.service
  • systemctl status votempd.service

Faster Boot without Ethernet

a) Let apache not wait for ethernet on boot (only wifi)

  • sudo nano /lib/systemd/system/network-online.target.wants/ifup-wait-all-auto.service
  • for i in $(echo "wlp1s0"); do INTERFACES="$INTERFACES$i "; done; \

b) change in /etc/network/interfaces

auto eth0 iface eth0 inet dhcp

to

allow-hotplug eth0 iface eth0 inet dhcp

Create WIFI Hotspot (Accesspoint/AP/Master Mode)

  • sudo apt-get install hostapd
  • sudo nano /etc/hostapd/hostapd.conf (see dist/etc-hostapd-hostapd.conf)
  • sudo nano /etc/default/hostapd => DAEMON_CONF="/etc/hostapd/hostapd.conf"

Network, DNS and DHCP

  • configure your wifi connection to a static ip. (see dist(etc-network-interfaces)
  • sudo apt-get install dnsmasq
  • sudo nano /etc/dnsmasq.conf (dhcp-range,listen-address,interface,address) (see dist/dnsmasq.conf)
  • sudo service dnsmasq restart

Playlists Information

  • .m3u playlists with one song per line. Linebreaks: \x0D\x0A Charset: UTF-8 (with Byte Order Mark (BOM), so files start with \xEF\xBB\xBF)
  • Paths have to be relative to your root dir. For example: "somedir/somefile.mp3" (without quotes)
