Install Python and Flask To begin, execute these commands in your terminal to install Python and Flask: sudo apt install python3.10-venv sudo apt-get install libapache2-mod-wsgi-py3 sudo a2enmod wsgi 3. Create a Virtual Environment Next, create and activate a virtual environment for your Flask application with the following commands: python -m venv flaskEnev source flaskEnev/bin/activate pip install flask 4. Create a Flask App You can use your existing project or follow these steps to create a simple "Hello World" application: 1.Set Up the Project Directory: Create a new directory and navigate into it: mkdir helloworld cd helloworld 2.Create the Application File: Open a new Python file named app.py: nano app.py 3.Write the Flask Application: Add the following code to app.py: from flask import Flask application = app = Flask(__name__) @app.route('/') def hello_world(): return 'Hello, World!' if __name__ == '__main__': app.run(debug=False) 5 Configure Apache to Serve Your Flask App To configure Apache to serve your Flask application, follow these steps: Create a Virtual Host Configuration 1.Navigate to the Sites-Available Directory: Create a new virtual host configuration file: cd /etc/apache2/sites-available nano testingSite.conf 2. Edit the Configuration File: 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/app.py] <Directory [project_folder]> WSGIProcessGroup [project_name] WSGIApplicationGroup [project_name] Order deny,allow Allow from all Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/[project_name]-error.log CustomLog ${APACHE_LOG_DIR}/[project_name]-access.log combined </VirtualHost> Test and Enable Your Site 3. Verify and Activate Your Configuration: Test and enable your new site configuration: sudo apachectl configtest sudo a2ensite testingSite.conf sudo systemctl reload apache2 At this point, your Flask application should be accessible via your domain. Conclusion Congratulations on successfully hosting your Flask website via an Apache Server using WSGI! If you have followed the steps correctly, your Flask app should now be live. Feel free to explore and expand your Flask application. If you have any questions or run into issues, don’t hesitate to seek help or refer to the documentation. Happy coding!
