Installing a Flask webapp on a Digital Ocean VPS (or Linode, etc.)
Here I sum up how to install a Flask webapp on a Digital Ocean VPS that has Ubuntu Linux on it. The following topics will be covered:
- server configuration
- the big picture
- Nginx
- a simple Flask app in a virtual environment served by gunicorn
- gunicorn is started automatically upon boot
Originally I wrote these notes for Ubuntu 14.04, but later it was updated for Ubuntu 16.04. Both versions are available:
- Ubuntu 14.04 -- gunicorn is started with upstart
- Ubuntu 16.04 -- gunicorn is started with systemd
