Easy Flask with NGINX

As one of the more popular Python frameworks, Flask is an extremely lightweight yet powerful system for web applications. Seen as more of a micro framework, a functional Flask application can be as simple as 20 lines of code.

Getting ready

application = Flask(__name__) 
 
@application.route("/") 
def hello(): 
    return "<h1>Demo via Nginx with uWSGI!</h1>" 
 
if __name__ == "__main__": 
    application.run(host='127.0.0.1', port=9001)

apt-get install python-pip python-dev
pip install uwsgi

How to do it...
