How to use Server with Gunicorn

Gunicorn (‘Green Unicorn’) is a pure-Python WSGI server for UNIX. It has no dependencies and is easy to install and use.

Installing Gunicorn

Installing gunicorn is as easy as python -m pip install gunicorn. For more details, see the gunicorn documentation.

Running Server in Gunicorn as a generic WSGI application

When Gunicorn is installed, a gunicorn command is available which starts the Gunicorn server process. At its simplest, gunicorn just needs to be called with the location of a module containing a WSGI application object named application. So for a typical Server project, invoking gunicorn would look like:

gunicorn myproject.wsgi

This will start one process running one thread listening on It requires that your project be on the Python path; the simplest way to ensure that is to run this command from the same directory as your file.

See Gunicorn’s deployment documentation for additional tips.
