4. Create a Flask App

You can use your own project or follow these steps to create a simple "Hello World" application:

  1. Create a new directory and navigate into it:

    mkdir helloworld
    cd helloworld
  2. Create a new Python file

  3. Add the following code to

from flask import Flask

application = app = Flask(__name__)

def hello_world():
return 'Hello, World!'

if __name__ == '__main__':

5 Configure Apache to Serve Your Flask App

1. Navigate to Apache is sites-available directory and create a new virtual host configuration file:
cd /etc/apache2/sites-available
nano testingSite.conf
2. Replace the placeholders in the configuration file with your specific details:
<VirtualHost *:80>
    ServerName [Your domain name]

    WSGIDaemonProcess [project_name] user=[your username] group=[your username] threads=5 python-home=[env dir ex=/home/john/flaskEnev]
    WSGIScriptAlias / [application folder ex=/home/john/helloworld/]

    <Directory [project_folder]>
        WSGIProcessGroup [project_name]
        WSGIApplicationGroup [project_name]
        Order deny,allow
        Allow from all
        Require all granted

    ErrorLog ${APACHE_LOG_DIR}/[project_name]-error.log
    CustomLog ${APACHE_LOG_DIR}/[project_name]-access.log combined
