Lighthouse Backend (Python360) Installation

Production Setup

1. What You Need

• Python 3.8 or newer

• PHP 8.1 or newer (for client applications)

• OpenSSL (for security)

• Basic system packages (the install script will handle most dependencies)

• Root/sudo access for service installation

• A version of PCR-360 compatible with Lighthouse

• A license for Lighthouse

2. Installation Steps

1. Get the code and navigate to project folder

# Clone or download the project
cd /path/to/python360

2. Generate the service configuration file Create the systemd service file with your SSL certificates:

   # Option 1: Use specific security certificates
./generate_service.sh --cert /path/to/cert.crt --key /path/to/key.key
   # Option 2: Let the script help you find existing certificates
./generate_service.sh
   # The script will search for certificates and show you options
   # Then run with the chosen paths:
./generate_service.sh --cert /path/to/cert.crt --key /path/to/key.key
   # Option 3: Set custom number of workers (optional)
   ./generate_service.sh --cert /path/to/cert.crt --key /path/to/key.key --workers 4

3. Install the service Run the installation script (this does everything automatically):

sudo ./install_service.sh

What the install script does automatically:

• Installs Python 3.8, venv, and pip if not present

• Creates the installation directory at /opt/python360/

• Copies all source files to the installation directory

• Creates a fresh virtual environment at /opt/python360/venv/

• Installs all Python dependencies from pyproject.toml into the virtual environment

• Downloads required AI models (sentiment analysis)

• Sets up all necessary directories (input, output, cache, etc.)

• Configures proper permissions for the www-data user

• Installs and enables the systemd service

• Starts the service automatically

4. Verify the installation Check if the service is running properly:

# Check service status
sudo systemctl status python360
   # View real-time logs
sudo journalctl -u python360 -f
# Check if the service is listening on the correct port
sudo netstat -tlnp | grep :8000
