SSH Installation Manual for Implementing on cPanel

Prerequisites:

• Ensure you have SSH access to your cPanel account.
• Have your SSH credentials ready.

1. Access Your cPanel Account via SSH

1. Open your terminal (Linux/Mac) or Command Prompt/PowerShell (Windows).
2. Connect to your cPanel account using SSH:

   ssh username@yourdomain.com

Replace username with your cPanel username and yourdomain.com with your domain name.

2. Set Up Python Application

1. Navigate to the Application Directory:

• If you haven’t created a directory for your application, create one and navigate to it:
  bash mkdir -p ~/myapp cd ~/myapp

1. Create a Virtual Environment:

• Create a Python virtual environment:
  bash python3 -m venv venv

1. Activate the Virtual Environment:

• Activate the virtual environment:
  bash source venv/bin/activate

1. Upload Your Project Files:

• If you haven’t uploaded your project files, you can use scp (from your local machine) to copy them over:
  bash scp -r /path/to/your/project/files username@yourdomain.com:~/myapp
• Alternatively, use an FTP client or the cPanel file manager to upload your files.

1. Install Required Packages:

• Ensure you have a requirements.txt file in your project directory and install the required packages:
  bash pip install -r requirements.txt

3. Configure the Application

1. Environment Variables:

• Create a .env file in your project directory with the necessary environment variables:
  bash touch .env nano .env
• Add your environment variables in the .env file:
  GRAPH_API_TOKEN=your_graph_api_token WEBHOOK_VERIFY_TOKEN=your_webhook_verify_token

1. Database Configuration:

• Ensure your Flask app configuration is set to point to your MySQL database. For example, in your app.py:
  python app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://username:password@host/database'

1. Initialize the Database:

• Run the following commands to create the database tables:
  bash python from app import db, app with app.app_context(): db.create_all() exit()

4. Deploy and Run the Application

1. Run the Flask Application:

• For development purposes, you can run the Flask app directly:
  bash export FLASK_APP=app.py flask run
• To keep the application running in the background, use a process manager like screen or tmux, or use a production server like gunicorn.

1. Using Gunicorn:

• Install Gunicorn:
  bash pip install gunicorn
• Run the application with Gunicorn:
  bash gunicorn -w 4 -b 0.0.0.0:8000 app:app

5. Set Up Webhook URL in WhatsApp Business API

1. Set the Webhook URL:

• Set the webhook URL in the WhatsApp Business API settings to point to your webhook endpoint (e.g., https://yourdomain.com/webhook).

1. Verify the Webhook:

• Ensure the webhook verification token matches the one set in your .env file.

6. Optional: Set Up a Reverse Proxy with Apache or Nginx

1. Apache Configuration:

• Open your Apache configuration file and add a reverse proxy configuration: <VirtualHost *:80> ServerName yourdomain.com ProxyPass / http://127.0.0.1:8000/ ProxyPassReverse / http://127.0.0.1:8000/ ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>
• Restart Apache:
  bash sudo systemctl restart httpd

1. Nginx Configuration:

• Open your Nginx configuration file and add a reverse proxy configuration: server { listen 80; server_name yourdomain.com; location / { proxy_pass http://127.0.0.1:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } error_log /var/log/nginx/error.log; access_log /var/log/nginx/access.log; }
• Restart Nginx:
  bash sudo systemctl restart nginx

By following these steps, you should be able to set up and run your Positive Chat AI WhatsApp application on cPanel using SSH successfully.
