This project has been tested on Debian 6 (recommended), Ubuntu 10.04, 10.10, and 11.10. If you're not using one of these distros then spare your sanity and set up a virtual machine.

Read this if you're using PostgreSQL 9.1:

Right now you can ignore most of the chat/real-time related stuff because I couldn't figure out how to make node.js/ not leak a ridiculous amount of memory. When the website was getting only 25,000 visitors a day it would leak about 300 megs of memory an hour. I'm pretty confident this wasn't my fault because most of those requests were being plugged into about 10 lines of code I wrote in the notifications section in chat/app.js.

Anyway here's how you get started!

Install dependencies:

wget -qO- | sudo bash

Perform some basic system changes:

sudo -u postgres -i createuser --superuser root   # make root a pg admin
sudo -u postgres -i createuser --superuser $USER  # make you a pg admin
sudo chmod go+rwt /opt  # let all users create files in /opt

Define pseudo hostnames by putting this in /etc/hosts:

Now we're going to run the install script to create a virtualenv, install the project, create the database, load the database content, and create a local settings file:

export PROJ="ows"
export DEST="/opt"
export REPO="$USER/occupywallst.git"  # did you make your github fork yet?
wget -qO- | bash
cd /opt/ows/occupywallst
source ../bin/activate

Now we'll setup nginx as our webserver:

sudo apt-get install nginx
sudo rm /etc/nginx/sites-enabled/default
sudo cp conf/ /etc/nginx/sites-available/
pushd /etc/nginx/sites-enabled/; sudo ln -sf ../sites-available/; popd
sudo /etc/init.d/nginx restart

Which will forward requests to our internally running webserver:

occupywallst runserver 9000

Then open this url :)

There's also a backend for modifying the database and writing articles. Go to and log in as user "OccupyWallSt" with the password "anarchy".

If you need to customize Django settings for your local install, do it inside occupywallst/


To run the regression tests:

occupywallst test occupywallst

Production Tips

Rather than using Django's "runserver" as the backend HTTP server, I recommend using gunicorn:

/opt/ows/bin/gunicorn_django -b --workers=9 --max-requests=1000 --pid=/tmp/ occupywallst/

AppArmor allows you to write mandatory access controls that will reduce the potential damage of future security exploits:

sudo aa-genprof /opt/ows/bin/gunicorn_django
sudo aa-complain /opt/ows/bin/gunicorn_django
# run gunicorn/occupywallst and do a bunch of stuff on the site
sudo aa-logprof
# restart gunicorn/occupywallst and do a bunch of stuff on the site
sudo aa-logprof
sudo nano -w /etc/apparmor.d/opt.ows.bin.gunicorn_django
sudo aa-enforce /opt/ows/bin/gunicorn_django

pgbouncer should be used to drastically reduce the number of processes postgres needs to run. Running fewer postgresql processes also means you can configure postgres to use lots of memory for better performance.

These fancy indexes will optimize the performance of certain slow queries:

-- optimize: recent comments on forum page
create index occupywallst_comment_published
  on occupywallst_comment (published desc)
  where (is_removed = false and is_deleted = false);
create index occupywallst_comment_published2
  on occupywallst_comment (published desc, user_id)
  where (is_deleted = false);

-- optimize: forum thread list
create index occupywallst_article_killed
  on occupywallst_article (killed desc)
  where (is_visible = true and is_deleted = false);
create index occupywallst_article_killed2
  on occupywallst_article (killed desc, author_id);

-- optimize: notifications
create index occupywallst_notifications_idx
  on occupywallst_notification (user_id, published)
  where (is_read = false);

Network Topology

When you run the kitchen sink, there are many network programs all working together and talking to each other. This should hopefully give you a better understanding of the system design in production:       nginx redirects browser to https      nginx load balancing proxy / media server  nginx redirects browser to https chat/app.js: node.js realtime http stuff chat/app.js: flashsocket policy server
udp:            chat/app.js: notification event subscriber
tcp:            gunicorn_django backend http server
tcp:            icecast2 mp3 streaming
tcp:            freeswitch mod_event_socket     freeswitch sip server     freeswitch sip server     freeswitch secure-sip server
tcp:           memcached
tcp:            postgresql database server
tcp:            pgbouncer database connection pooler


Getting testing to run requires some work, because of the GIS business. Notes on it here:

Do the following:

POSTGIS_SQL_PATH=`pg_config --sharedir`/contrib
createdb -E UTF8 template_postgis
createlang -d template_postgis plpgsql
# Allows non-superusers the ability to create from this template
psql -d postgres -c "UPDATE pg_database SET datistemplate='true' WHERE datname='template_postgis';"
# Loading the PostGIS SQL routines
psql -d template_postgis -f $POSTGIS_SQL_PATH/postgis.sql
psql -d template_postgis -f $POSTGIS_SQL_PATH/spatial_ref_sys.sql
# Enabling users to alter spatial tables.
psql -d template_postgis -c "GRANT ALL ON geometry_columns TO PUBLIC;"
#psql -d template_postgis -c "GRANT ALL ON geography_columns TO PUBLIC;"
psql -d template_postgis -c "GRANT ALL ON spatial_ref_sys TO PUBLIC;"

Then you should be able to run tests as follows (note that this must be run from the project dir):

occupywallst-dev test
occupywallst-dev test occupywallst  # faster
