Project Setup and Execution Guide

This README provides instructions on setting up a Python virtual environment, installing required packages, configuring ChromeDriver for Selenium, and running the script using pm2 or screen on a Linux system.

Prerequisites

Ensure you have the following installed on your system:

• Python 3
• pip (Python package installer)
• Node.js and npm
• pm2 (Node process manager)

Step 1: Install Python, Xvfb, and Node.js

Run the following commands to install Python3, Xvfb, Node.js, and npm:

sudo apt update
sudo apt install python3 python3-venv python3-pip xvfb nodejs npm -y

Step 2: Install pm2

Install pm2 globally to manage the process:

sudo npm install -g pm2

Step 3: Create a Virtual Environment

1. Create a project directory (e.g., Main) and navigate into it:

   mkdir Main && cd Main

2. Set up the virtual environment:

   python3 -m venv Main

3. Activate the virtual environment:

   source Main/bin/activate

Step 4: Install Project Dependencies

Ensure your requirements.txt file is in the Main folder. Install dependencies with:

python -m pip install -r requirements.txt

ChromeDriver Setup for Selenium

Step 1: Check Your Chrome Version

Open Chrome and go to chrome://settings/help to find your version of Chrome (e.g., Chrome 115).

Step 2: Download ChromeDriver

1. Go to the ChromeDriver download page.

2. Download the version matching your Chrome version:

   wget https://chromedriver.storage.googleapis.com/<version>/chromedriver_linux64.zip

   Replace <version> with the ChromeDriver version (e.g., 115.0.5790.170).

3. Extract the downloaded file:

   unzip chromedriver_linux64.zip

4. Move ChromeDriver to a directory in your PATH:

   sudo mv chromedriver /usr/local/bin/

5. Verify ChromeDriver is installed:

   chromedriver --version

Running the Python Script

Option 1: Using pm2 to Run the Script

To run the script with pm2 using xvfb:

pm2 start "xvfb-run -a python Main/seleniumV2.py" --name VFS

Managing pm2

• List all processes: pm2 list
• Restart the process: pm2 restart VFS
• Stop the process: pm2 stop VFS
• Delete the process: pm2 delete VFS
• View logs: pm2 logs VFS

To enable pm2 startup on reboot:

pm2 startup
pm2 save

Option 2: Using screen to Run the Script

1. Start a new screen session:

   screen -S VFS

2. Run the script:

   source Main/bin/activate
   xvfb-run -a python Main/seleniumV2.py

3. Detach from the screen session:

   • Press Ctrl + A, then D to detach without stopping the script.

4. Reattach to the screen session:

   screen -r VFS

5. Terminate the session:

   • Reattach to the session, stop the script, then type exit to close the screen session.
