Note : This demo site will removed after a few days.
Setup instructions on Ubuntu 16.04:
Follow this guide for the initial server setup.
Update package index :
sudo apt-get update
Install dependencies :
sudo apt-get install python3-pip python3-dev libpq-dev postgresql postgresql-contrib nginx

CREATE DATABASE djangochat;
CREATE USER djangochatuser WITH PASSWORD 'YOUR_PASSWORD';
ALTER ROLE djangochatuser SET client_encoding TO 'utf8';
ALTER ROLE djangochatuser SET default_transaction_isolation TO 'read committed';
ALTER ROLE djangochatuser SET timezone TO 'UTC';

\q
Setup Django project :
git clone https://github.com/ploggingdev/djangochat.git
sudo apt install python3-venv
cd djangochat
mkdir venv
python3 -m venv venv/djangochat
source venv/djangochat/bin/activate
pip install -r requirements.txt
pip install --upgrade pip
Add environment variables :
sudo nano ~/.bashrc
#append the following to the end of the file
export djangochat_secret_key="SECRET_KEY"
export djangochat_db_name="djangochat"
export djangochat_db_user="djangochatuser"
export djangochat_db_password="YOUR_PASSWORD"

Perform database migration :
python manage.py migrate
Install redis by following this guide.
Create Django superuser :
python manage.py createsuperuser
Configure django-channels-presence pruning of websocket connections (this is necessary to remove inactive websocket connections) :
Go to the /admin/django_celery_beat/periodictask/add/ panel and add a custom task channels_presence.tasks.prune_presence with an interval of your choice. I used 60 seconds for testing purposes.
Start the development server :
python manage.py runserver
Start celery :
celery -A chatdemo beat -l info -S django
Visit the local development server at 127.0.0.1:8000 to test the site.
