In this beginner-friendly tutorial, I explain how to set up a Selenium Scrapper in Flask on EC2. If you are stuck trying to do it or just beginning to wonder What is Selenium then this blog is a great place to get started.

The prerequisite to this Tutorial is just that you have a running EC2 instance on AWS and you are connected to it.

If not this will help you.

⚠️⚠️ WARNING ⚠️⚠️

Before going ahead with this tutorial make sure that your Security Group on your EC2 instance has HTTP access from anywhere and also exposed the 5000 port number as it is very important. Else you won't be able to access the site at the end of this tutorial.


Step 1.

Start a new screen and become root user

sudo su

Step 2.

Install python3 , pip, git and virtualenv

yum install python3 -y
yum install git -y
yum install pip
pip install virtualenv

Step 3.

Create a virtual environment with python3 and activate that environment. Replace 3.7 with whatever version you have. To get version use:

python3 --version

Create a new virtual env name my-app

virtualenv -p python3.7 my_app

Activate virtual env

source ./my_app/bin/activate

Step 4.

You need some browser to run webdrivers. I am using chrome browser and chrome webdriver here.


It is important to download browser first and then identify it's version and accordingly install webdriver for that particular version. Please follow these steps carefully.

Enter the below command to install chrome

curl https://intoli.com/install-google-chrome.sh | bash
sudo mv /usr/bin/google-chrome-stable /usr/bin/google-chrome

To get the version of google chrome installed

google-chrome --verison

The above code will print the chrome version.

Now go to the following website to get the suitable webdriver for that particular version of chrome.

now my version of chrome is 104.

Click on your driver link and from there copy the link to Linux O.S.

wget https://chromedriver.storage.googleapis.com/104.0.5112.79/chromedriver_linux64.zip
unzip chromedriver_linux64.zip
sudo mv chromedriver /usr/bin/chromedriver

To check if chrome driver is installed or not

chromedriver --version

Step 5.

Install necessary python libraries

Now we will install all necessary lib in python using pip

pip install flask
pip install selenium
pip install waitress

Step 6.

Run the program

mkdir your_repo && cd your_repo/

use your fav editor to paste this code into the application.py file.

from selenium import webdriver
from flask import Flask
from selenium.webdriver.chrome.options import Options
from waitress import serve
app = Flask(__name__)

def hello():
    options = Options()
    driver = webdriver.Chrome(options=options)
    element_text = driver.page_source
    return element_text

if __name__ == '__main__':
    serve(app,host = '',port = 5000)

and run the below command in the command terminal after saving the application.py file.

python application.py

The above code will return the HTML source code of the google home page. You are basically running selenium webdriver here and getting the site data of google.com. You can change it to any website you like to scrap.

Use the public IP of your EC2 instance and add the :5000 port number in back of the Public URL.(use HTTP instead of HTTPS)




When the website is google.com


When the website is youtube.com
