Python Django+uWsgi+Nginx没有数据库数据，加上502页面更改错误

我试图让我的生产门户网站用Django编写，但是我遇到了一些问题。该页面将解析为登录页面，身份验证将起作用并将您带到第一个页面。然而，没有任何数据库数据将在那里，而且，如果我尝试切换页面，它将给我一个502错误

当我使用Django web服务器时，一切都正常工作。我相信这只是uWsgi设置的问题。这是我第一次使用django将服务器发布到生产环境中，因此我对自己的知识缺乏表示歉意

This is the error that triggers inside the log file upon switching pages
2014/10/22 17:19:03 [error] 21424#0: *1 upstream prematurely closed connection while reading response header from upstream, client: 172.17.1.16, ser$

我读到这是因为需要设置uWsgi文件：

设置为：

我的项目/应用程序结构是

uWsgi配置：

Nginx配置：

my settings.py文件

---

我也有类似的问题。django运行的服务器一切正常，但在uwsgi中，我遇到了一个数据库访问错误。我的解决方案是确保pythonpath配置正确。 确保它已配置

尝试将其更改为硬编码链接，而不是：

pythonpath=%base/%projectname

---

尝试使用UNIX套接字，TCP端口可能会有问题。
