How to deploy Flask Apache on DigitalOcean

Flask is used to develop web apps quickly. It is a micro-framework written in Python. Today, we are going to explore deploying Flask on Apache on DigitalOcean.

Step 1: Installation

1. First, open the terminal and run the following command to install mod_wsgi.

   sudo apt-get install libapache2-mod-wsgi python-dev
2. Then run this command to enable it:

   sudo a2enmod wsgi

Step 2: Create a Flask App

1. First, we have to create a Flask app.
2. Then, move it to the /var/www directory.
3. Next, create an application directory structure with mkdir command as seen below.

   
4. Then create __init__.py file and add the following flask application logic:

   
5. Finally, save and exit the file.

Step 3: Create a virtual environment for Flask app

1. First install virtualenv and Flask via pip.

   sudo pip install virtualenv
2. Then, activate the virtual environment with the following command to install Flask:

   source venv/bin/activate
3. Then run the following command to install Flask inside:

   sudo pip install Flask
4. Finally, test if the installation process is successful with this command:

   sudo python __init__.py

Step 4: Configure and Enable a New Virtual Host

1. First, run this command on the terminal:

   sudo nano /etc/apache2/sites-available/FlaskApp
2. Then add these lines to the file:

   
3. Next, save and close the file.
4. After that, enable the virtual host with this command:

   sudo a2ensite FlaskApp

Step 5: Configure and Enable a New Virtual Host

1. Now, we will head to the /var/www/FlaskApp directory.
2. Then we have to create a file named flaskapp.wsgi and add the following lines:

   #!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/FlaskApp/") from FlaskApp import app as application application.secret_key = 'Add your secret key'

Now, the directory structure will look like this:

Step 6: Restart Apache

Finally, we have to restart Apache for the changes to take place.

Sometimes. We may come across the following message:

Could not reliably determine the VPS’s fully qualified domain name, using 127.0.0.1 for ServerName

This is a warning message and will not hinder access to the virtual host. Now, we can view the application by navigating to the IP address or domain name in a browser.
