Straight forward Nginx reverse proxy installation - no uwsgi

Here you go; this is a stripped-down version of the Nginx+uWSGI guide which simply performs a proxy_pass to a backend webserver.

You'll first need to create a new Custom Application (listening on port) in your applications list, and then should be able to fill in the beginning variables and proceed with the following commands. I tested this on on CentOS 7 as well. Hope that helps!

# Set environment variables
APPNAME=mynginx            # Name of the Nginx Custom Application
APPPORT=12345              # Assigned port for the Nginx Custom Application
BACKENDPORT=77777          # Localhost port where backend server listens
