Setup Flask-Nginx-SSL

Setup Flask-Nginx-SSL

Step 1:

Install the Pre-Requiresties:

sudo apt-get install python3-pip python3-dev Nginx

create virtualenv

activate virtualenv

Install the gunicorn inside the virtualenv that you have created now

pip install gunicorn

Step 2:

Create WSGI File in your project home directory:

vim project/wsgi.py

Paste this below code into wsgi.py file

from views import app#Here views is my flask run server file, you #can mention your run server package   
     
if __name__ == “__main__”:
 app.run()

To check wsgi configuration run the following command:

gunicorn — bind 0.0.0.0:5000 wsgi:app
or
gunicorn -b localhost:5000 -w 4 flask_app:app

Now deactivate the virtualenv

deactivate virtualenv

Step 3:

Create a systemd Unit File
systemd unit file will allow Ubuntu’s init system to automatically start Gunicorn and serve our Flask application whenever the server boots.
Create a unit file ending in .service within the /etc/systemd/system directory to begin :

sudo vim /etc/systemd/system/app.service
