瞭解gunicorn和Django

Question

我想了解gunicorn是如何與Django一起工作的。

上Running Django in Gunicorn as a generic WSGI application文檔說：

At its simplest, gunicorn just needs to be called with the location 
of a module containing a WSGI application object named application. 

所以，你可以這樣做：

$ gunicorn myproject.wsgi 

它將運行。但是這到底是什麼呢？我正在查看我的Django項目的根目錄，但沒有名爲myproject.wsgi的文件。那麼魔法背後是什麼？

的docs also say說：

Gunicorn will look for a WSGI callable named application if not specified. 

這是什麼意思？什麼是我的Django應用程序中的「應用程序」？我應該將它指定爲我的Django應用程序的名稱嗎？

Answer 1

您應該在django項目的根目錄下創建一個wsgi.py文件（使用django-admin startproject myproject創建）。

這wsgi.py有application調用：

""" 
WSGI config for myproject project. 

It exposes the WSGI callable as a module-level variable named ``application``. 

For more information on this file, see 
https://docs.djangoproject.com/en/1.7/howto/deployment/wsgi/ 
""" 
import os 

from django.core.wsgi import get_wsgi_application 

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings") 

application = get_wsgi_application()
