* Prepare Environment
1) add pandora user and set permissions
   adduser pandora --disabled-login --disabled-password

2) Setup Database
   su postgres
   createuser pandora
   createdb  -T template0 --locale=C --encoding=UTF8 -O pandora pandora
   echo "CREATE EXTENSION pg_trgm;" | psql pandora
   exit

3) Setup RabbitMQ

    rabbitmqctl add_user pandora use_your_own
    rabbitmqctl add_vhost /pandora
    rabbitmqctl set_permissions -p /pandora pandora ".*" ".*" ".*"


* Install Pan.do/ra
1) Get code from bazzar
    cd /srv/
    bzr branch http://code.0x2620.org/pandora pandora
    cd pandora
    virtualenv --system-site-packages .
    pip -E . install -r requirements.txt

    cd static
    bzr branch http://code.0x2620.org/oxjs

    cd /srv
    chown -R pandora.pandora pandora

2) create local_settings.py and config.jsonc

1) create file /srv/pandora/pandora/local_settings.py with the following content:
    DATABASES = {
        'default': {
            'NAME': 'pandora',
            'ENGINE': 'django.db.backends.postgresql_psycopg2',
            'USER': 'pandora',
            'PASSWORD': '',
        }
    }
    DB_GIN_TRGM = True
    BROKER_PASSWORD = "use_your_own"

    #with apache x-sendfile or lighttpd set this to True
    XSENDFILE = False

    #with nginx X-Accel-Redirect set this to True
    XACCELREDIRECT = True

2) create config.jsonc
    config.jsonc holds the configuration for your site.
    To start you can copy /srv/pandora/pandora/config.pandora.jsonc
    to /srv/pandora/pandora/config.jsonc but have a look at 
    https://wiki.0x2620.org/wiki/pandora/configuration and
    config.0xdb.jsonc config.padma.jsonc for configuration options.

3) initialize database
    su pandora
    cd /srv/pandora/pandora
    ./manage.py syncdb --noinput
    ./manage.py sqlfindindex | ./manage.py dbshell
    ./manage.py collectstatic -l --noinput
    ./manage.py update_static
    ./manage.py compile_pyc

4) install init scripts and start daemons
    cp /srv/pandora/etc/init/*.conf /etc/init/
    service pandora start
    service pandora-encoding start
    service pandora-task start

5) Setup Webserver
a) nginx (recommended)
    apt-get install nginx
    cp /srv/pandora/etc/nginx/pandora /etc/nginx/sites-available/pandora
    cd /etc/nginx/sites-enabled
    ln -s ../sites-available/pandora

    #read comments in /etc/nginx/sites-available/pandora for setting
    #your hostname and other required settings
    #make sure XACCELREDIRECT = True in /srv/pandora/pandora/local_settings.py
    
    service nginx reload

b) apache2 (if you need it for other sites on the same server)
    apt-get install apache2-mpm-prefork libapache2-mod-xsendfile
    a2enmod xsendfile
    cp /srv/pandora/etc/apache2/pandora.conf /etc/apache2/sites-available/pandora.conf
    a2ensite pandora

    #read comments in /etc/apache2/sites-available/pandora.conf for setting
    #your hostname and other required settings
    #make sure XSENDFILE = True in /srv/pandora/pandora/local_settings.py
    
    service apache2 reload


Now you can open pandora in your browser, the first user to sign up will become admin.


* A note about providing H.264 versions
    For H.264 videos, you need ffmpeg with x264 and libfaac enabled,
    you also need to install qt-faststart (from ffmpeg/tools)
    (you can use medibuntu.org packages or compile ffmpeg yourself)
    to enable H.264 derivatives add "mp4" to video.formats in your config.jsonc


=== Updating ===
To update a pandora installation get the latest version from bzr by running
    ./update.sh

this will update pandora/oxjs/python-ox and list possible upgrades to the db

to update your database tables, use
  su pandora
  cd /srv/pandora/pandora
   ./manage.py sqldiff -a
to check if there are changes and
   ./manage.py sqldiff -a | ./manage.py dbshell
to apply them.


=== Development ===
  in one terminal:
    ./manage.py runserver

  and background task in another:
    ./manage.py celeryd -B -Q celery,default,encoding

  now you can access your local pandora instace at http://127.0.0.1:8000/

  we use virtual machines for development, you can get a vm from our site
  or use the script in vm/build.sh to create one.
