2. 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 wsgi3. 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 helloworld2.Create the Application File: Open a new Python file named app.py:
nano app.py3.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.conf2. 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!
