[Flask] Deploying Flask on Debian

[Alex Hall]

Thanks for the help thus far, everyone. Just a quick update to say that I
got Nginx installed on Jessie. The problem was that, though I'd killed
Apache2, it hadn't stopped. I stopped it again, and this time the Nginx
installation went smoothly. I still see the Apache index page, but I
suspect that's because Nginx is looking in /var/www and just serving the
index.html file it finds, which is the Apache file.

Anyway, since that works and people here seem to prefer Nginx, I'll try to
use Flask with Nginx first before reverting to Apache should I fail. Back
to the Digital Oceans tutorial I go.
