Quick start: install larigira on Debian buster
==============================================

This guides have this assumptions or conventions:
 * you have a Debian buster installation
   - actually 99% of this should work in any distro with recent-enough python3 and systemd
   - if you don't like systemd, you are free to use any other service manager; larigira integrates nicely with systemd, but has no requirement at all on it.
 * you have a non-root main user, which we'll call ``radio``
 * all commands are meant to be run as root. Use ``sudo -i`` if you don't have root password

Install
-----------


Let's start!::

   apt-get install python3 python3-dev virtualenv mpd
   virtualenv -p /usr/bin/python3 /opt/larigira/
   /opt/larigira/bin/pip3 install larigira
   touch /etc/default/larigira
   mkdir -p /home/radio/.mpd/ /etc/larigira/ /var/log/larigira/
   chown radio:adm /var/log/larigira/
   touch /etc/systemd/system/larigira.service

Edit ``/etc/systemd/system/larigira.service`` and put this content::

   [Unit]
   Description=Radio Automation
   After=mpd.service

   [Service]
   EnvironmentFile=/etc/default/larigira
   User=radio
   ExecStart=/opt/larigira/bin/larigira

   [Install]
   WantedBy=multi-user.target

Now let's edit ``/etc/mpd.conf``::

   music_directory		"/home/radio/Music/"
   playlist_directory		"/home/radio/.mpd/playlists"
   db_file			"/home/radio/.mpd/tag_cache"
   log_file			"syslog"
   pid_file			"/home/radio/.mpd/pid"
   state_file			"/home/radio/.mpd/state"
   sticker_file                   "/home/radio/.mpd/sticker.sql"
   user				"radio"
   bind_to_address		"/home/radio/.mpd/socket"
   bind_to_address			"127.0.0.1"
   port				"6600"
   log_level			"default"
   replaygain			"track"
   replaygain_limit		"yes"
   volume_normalization		"yes"
   max_connections "30"

Now let's edit larigira settings, editing the file ``/etc/default/larigira``::
   
   MPD_HOST=/home/radio/.mpd/socket
   LARIGIRA_DEBUG=false
   LARIGIRA_LOG_CONFIG=/etc/larigira/logging.ini

   LARIGIRA_EVENT_FILTERS='["percentwait"]'
   LARIGIRA_EF_MAXWAIT_PERC=400
   LARIGIRA_SECRET_KEY="changeme"

Let's include logging configuration, editing ``/etc/larigira/logging.ini``::

   [loggers]
   keys=root

   [formatters]
   keys=brief,ext,debug

   [handlers]
   keys=syslog,own,owndebug,ownerr

   [logger_root]
   handlers=syslog,own,owndebug,ownerr
   level=DEBUG

   [handler_syslog]
   class=handlers.SysLogHandler
   level=INFO
   args=('/dev/log', handlers.SysLogHandler.LOG_USER)
   formatter=brief

   [handler_own]
   class=handlers.WatchedFileHandler
   level=INFO
   args=('/var/log/larigira/larigira.log',)
   formatter=ext
   [handler_owndebug]
   class=handlers.WatchedFileHandler
   level=DEBUG
   args=('/var/log/larigira/larigira.debug',)
   formatter=debug
   [handler_ownerr]
   class=handlers.WatchedFileHandler
   level=ERROR
   args=('/var/log/larigira/larigira.err',)
   formatter=ext

   [formatter_ext]
   format=%(asctime)s|%(levelname)s[%(name)s] %(message)s

   [formatter_debug]
   format=%(asctime)s|%(levelname)s[%(name)s:%(lineno)d] %(message)s

   [formatter_brief]
   format=%(levelname)s:%(message)s

For hygiene's sake, let's configure rotation for this log, editing ``/etc/logrotate.d/larigira``::

   /var/log/larigira/*.err
   /var/log/larigira/*.log {
           daily
           missingok
           rotate 14
           compress
           notifempty
           copytruncate
           create 600
   }

   /var/log/larigira/*.debug {
           daily
           rotate 2
           missingok
           compress
           notifempty
           copytruncate
           create 600
   }


Restart everything::

   systemctl daemon-reload
   systemctl restart mpd
   systemctl restart larigira
   systemctl enable larigira
   systemctl enable mpd


Everything should work now!
