#Setup Environment #Install Git #Install python tools & nginx(Optional)

$ sudo yum update $ sudo yum install python3 (If not installed already) $ sudo yum install python-pip3

$ sudo pip3 install virtualenv

$ cd Hello_Flask_App

$ virtualenv venv

$ source ./venv/bin/activate

Now the prompt should look like: (venv)user@host:~/Hello_Flask_App$

(venv)user@host:~/Hello_Flask_App$ pip3 install gunicorn flask

(venv)user@host:~/Hello_Flask_App$ python app.py

Go to your browser and enter the url to your server, appending the port number you specified in app.py. You should see Hello World! displayed

Create the WSGI entrypoint ~/Hello_Flask_App/wsgi.py.

(venv)user@host:~/Hello_Flask_App$ gunicorn --bind 0.0.0.0:8080 wsgi:app

#Note: If you didn't name your app as application, for example as app, use wsgi:app instead of wsgi, since application is the name to be picked up by default.

Go to your browser again and read the Hello World! response
