Django和uWSGI 2 Emperor模式的内部服务器错误

Question

我一直在努力阅读有关这个​​问题的所有内容（并且在这样做时学到了很多东西）。 我能找到的最近的链接就在这里和这里 。 除了我在emperor模式下专门运行uwsgi之外，我的问题几乎完全相同。 当我运行uswsgi服务而没有在emperor模式下运行时，我的django网站运行得很好。 无论我如何更改配置，我总是收到错误消息my /tmp/uwsgi.log文件：“---找不到python应用程序，检查启动日志中的错误---”我已在下面列出了我的配置和错误日志：

操作系统版本：Linux raspberrypi 3.6.11+＃538 armv6l GNU / Linux
Django版本：1.6.5
uwsgi版本：2.0.5.1

虚拟环境：/ var / www / testbed / env
项目地点：/ var / www / testbed / project / auth
项目树：

文件wsgi.py：

"""
WSGI config for auth project.

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

在这一点上，我正在抓住稻草。 在我所做的所有阅读中，我无法理解为什么这会一直呈现“内部服务器错误”。 我可能已经看了一些东西，为什么我最终通过在这里发布我的悲伤而让自己感到骄傲。 自从我走到这一步以来，我确实认为我忽略了一些非常小的东西。 任何帮助将不胜感激。

Answer 1

我在使用usgi-emperor的部署中多次遇到过这个问题，问题是我没有在我的Django的项目配置文件中设置正确的ALLOWED_HOSTS

在您的配置中，你会有

ALLOWED_HOSTS=[ "yourdomain.com", "other.domain.com" ]

或者这（ 因安全问题而气馁，使用风险自负 ）：

ALLOWED_HOSTS=["*"]

允许任何主持人
