nginx+gunicorn+django+aws 错误请求

Question

我正在关注https://ashokfernandez.wordpress.com/2014/03/11/deploying-a-django-app-to-amazon-aws-with-nginx-gunicorn-git/ 的教程 关于部署 django 应用程序。这是我目前的情况：

fab spawn 实例创建了安装了 nginx 和 gunicorn 的 aws 实例，但是当我尝试访问该机器上的站点时，我收到了 400 Bad Request。我检查了 nginx-error 日志，但它是空的，并且 nginx-access 日志显示它已收到请求。主管日志有以下内容：

我将 ALLOWED_HOSTS 从 [] 更改为 ["*"] 然后 '*' 当我将其更改为字符串时，我得到“在此服务器上找不到请求的 URL /”。在其他情况下，我收到了 400 个错误请求。

这是我第一次在 nginx 上部署 django 应用程序，我无法弄清楚问题可能是什么。你能帮我调试这个错误吗？ 提前致谢！！

PS：如果我需要发布任何配置文件，请告诉我。到目前为止，我只是按照教程进行操作，还没有更改任何配置。

更新： common.py

import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
SECRET_KEY = 'blah'
ALLOWED_HOSTS = []

在我的项目配置文件中我也有 fabconf['DOMAINS'] = "" 我认为这也可能是相关的

允许的主机必须与您将使用的主机名相匹配。因此，将ALLOWED_HOSTS = [] 放入特定于您的环境（开发或生产）的设置文件中。在开发端将其设置为ALLOWED_HOSTS = ['localhost', '127.0.0.1']，在生产端将它设置为您的域和服务器 IP。

来自文档：

此列表中的值可以是完全限定名称（例如'www.example.com'），在这种情况下，它们将与请求的Host 标头完全匹配（不区分大小写，不包括端口）。以句点开头的值可用作子域通配符：'.example.com' 将匹配 example.com、www.example.com 和 example.com 的任何其他子域。 '*' 的值将匹配任何内容；在这种情况下，您有责任提供自己对 Host 标头的验证（可能在中间件中；如果是这样，则此中间件必须首先在 MIDDLEWARE_CLASSES 中列出）。

您收到的状态 400 响应是由于当您的主机标头与该列表中的任何值都不匹配时引发了 SuspiciousOperation exception。
