pan.do/ra - open media archive
== SETUP ==
pan.do/ra is known to work with Ubuntu 12.04, older versions of
Ubuntu or other distributions should work
if the dependencies are up to date.
To setup pan.do/ra, you need python, bazaar, pip and virtualenv
and several other python modules:
* Packages
(add pandora ppa to get all packages in the required version)
apt-get install python-software-properties
add-apt-repository ppa:j/pandora
apt-get update
(install dependencies)
apt-get install bzr git subversion mercurial \
python-setuptools python-pip python-virtualenv ipython \
python-dev python-imaging python-numpy python-psycopg2 \
python-geoip python-html5lib python-lxml \
postgresql postgresql-contrib rabbitmq-server \
ffmpeg2theora ffmpeg \
python-ox oxframe oxtimeline
* Pan.do/ra
Get code from bazzar
cd /srv/
bzr branch http://code.0x2620.org/pandora pandora
cd pandora
virtualenv .
pip -E . install -r requirements.txt
cd static
bzr branch http://code.0x2620.org/oxjs
create local_settings.py and create site.jsonc in /srv/pandora/pandora
do noy copy settings.py but only add your changes to local_settings.py
(check https://wiki.0x2620.org/wiki/pandora/configuration
and use settings.py / config.jsonc / config.*.jsonc as example)
create and configure database as described below
after that
create / update static files
./manage.py update_static
./manage.py compile_pyc
* Database
We use postgresql but other databases might also work
(make sure you have the python bindings installed).
create a postgresql database
sudo -u postgres createdb -T template0 --locale=C --encoding=UTF8 -O pandora pandora
(setting locale to C is required to fix a bug in sort if set to UTF8)
now add settings to local_settings.py:
DATABASES = {
'default': {
'NAME': 'pandora',
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'USER': 'pandora',
}
}
and run ./manage.py syncdb to populate the database.
Optionaly use pg_trgm to improve find speed (requires postgres 9.1 and postgresql-contrib)
echo "CREATE EXTENSION pg_trgm;" | sudo -u postgres psql pandora
./manage.py sqlfindindex | ./manage.py dbshell
echo "DB_GIN_TRGM = True" >> local_settings.py
* RabbitMQ
For background tasks RabbitMQ is required, to install rabbitmq:
sudo apt-get install rabbitmq-server
and create permissions according to BROKER_* in local_settings.py i.e.:
sudo rabbitmqctl add_user pandora box
sudo rabbitmqctl add_vhost /pandora
sudo rabbitmqctl set_permissions -p /pandora pandora ".*" ".*" ".*"
* H264
for h264 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 h264 derivatives add "mp4" to video.formats in your config.jsonc
== Deployment ==
* Install upstart scripts
check etc/init for upstart scripts, adjust path and user and put into /etc/init
To run pan.do/ra in production, we use nginx, using apache2 is also possible.
* nginx setup
sudo apt-get install nginx
add this to local_settings.py:
XACCELREDIRECT = True
setup nginx according to etc/nginx/vhost.in
* apache2 setup
apt-get install apache2-mpm-prefork libapache2-mod-xsendfile
add this to local_settings.py:
XSENDFILE = True
setup apache according to etc/apache2/vhost.in
now you can start pandora services:
service pandora start
service pandora-tasks start
service pandora-encoding start
=== 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
./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 default,encoding
