If you want to deploy the application cloud please follow the below instructions:

Install the Packages from the Ubuntu Repositories

sudo apt-get update
sudo apt-get install python3-pip python3-dev libpq-dev postgresql postgresql-contrib nginx

Create the PostgreSQL Database and User

sudo -u postgres psql

CREATE DATABASE streaming;
CREATE USER dev WITH PASSWORD '12345';
ALTER ROLE dev SET client_encoding TO 'utf8';
ALTER ROLE dev SET default_transaction_isolation TO 'read committed';
ALTER ROLE dev SET timezone TO 'UTC';
GRANT ALL PRIVILEGES ON DATABASE streaming TO dev;
\q

Create a Python Virtual Environment & run project

git clone https://github.com/mbrsagor/streaming.git
cd streaming
git checkout develop
sudo apt install python3-virtualenv
virtualenv venv --python=python3.10
source venv/bin/activate
pip install -r requirements.txt

Create .env file and paste info from .sample_env file.

EMAIL_USE_TLS=False

# Database config

DB_PASSWORD=12345

Migrations and create superuser.

python manage.py makemigrations
python manage.py migrate
python manage.py collectstatic
python manage.py createsuperuser

Create a Gunicorn systemd Service File

sudo nano /etc/systemd/system/gunicorn.socket

[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target

Next, we will create a service file for gunicorn

sudo vim /etc/systemd/system/gunicorn.service

Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=ubuntu
Group=www-data
WorkingDirectory=/home/ubuntu/streaming
ExecStart=/home/ubuntu/streaming/venv/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/gunicorn.sock \
          streaming.wsgi:application
[Install]
WantedBy=multi-user.target

With this command, you can check if already a file exists.

cd /etc/nginx/sites-enabled

Configuring Nginx as a reverse proxy

sudo vim /etc/nginx/sites-available/streaming

server {
    listen 80;
    server_name IP_ADDRESS;
    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/ubuntu/streaming;
    }
    location /media/ {
        root /home/ubuntu/streaming;
    }
    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

Activate the configuration using the following command:

sudo ln -s /etc/nginx/sites-available/streaming /etc/nginx/sites-enabled/

Run this command to load a static file

sudo gpasswd -a www-data ubuntu

sudo systemctl restart nginx
sudo service gunicorn restart
sudo service nginx restart
