pkill gunicorn stops all gunicorn daemons. So if you are running multiple instances of gunicorn with different ports, try this shell script. ps ax | grep gunicorn | grep $Port shows the daemons with specific port.
This confirms that Gunicorn was started and able to serve your Django application. You can verify that the Gunicorn service is running by checking the status again: sudo systemctl status gunicorn.
The Gunicorn process will start and bind to all host IP addresses on port 8081.
Gunicorns takes care of running multiple instances of your web application, making sure they are healthy and restart them as needed, distributing incoming requests across those instances and communicate with the web server. In addition to that, Gunicorn is pretty darn fast about it.
Use --daemon option while running gunicorn.
Example:
gunicorn grand56.wsgi:application --name grand56 --workers 3 --user=root --group=root --bind=127.0.0.1:1001 --daemon
use --daemon to the binding command of gunicorn. ex:
gunicorn --bind 0.0.0.0:8001 your_project.wsgi --daemon
I'd look into something like Supervisor.

The key thing to note is that when you start the process from the command line it is a child of your terminal process (i. e. a child of bash). When you log out of the server your bash process is terminated - as are all its children.
You'll want to use whatever system you have in place to manage nginx also manage gunicorn (anything from init.d or Upstart scripts to specialized application process monitors like Monit, Supervisor, Bluepill, Foreman, etc.)
Try this:
nohup gunicorn app:app &
