我有一个 Django 应用程序，它使用 uWSGI 和 Nginx 进行生产部署。现在我正在集成 Channels 2.0 并意识到 Daphne 是这里 uwsgi 的替代品。我可以让 Daphne 在独立模式下运行它，但是当我尝试在 nginx 代理后面运行它时，我不断收到连接超时（504）

我的 nginx 配置文件是我为 uWSGI 服务器配置的，我希望它能够正常工作，因为套接字名称是相同的。

可能的问题：

  • 从 nginx 日志中的样子来看，nginx 尝试连接到，uwsgi://unix:///path/to/nginx.sock但我认为它不uwsgi应该以unix:///path/to/nginx.sock.

后续问题：

  • 是否建议同时使用 Daphne 来服务器 http 和 websocket？或者我应该将 uWSGI 用于 http，而 Daphne 仅用于 websocket。
  • 如果两者都使用 Daphne，我是否正确保留相同的 uwsgi_params 文件？

  location /static {

  }

  # Finally, send all non-media requests to the Django server.
  location / {
    uwsgi_pass  home;
    include     /Users/pranavprakash/workspace/HomeApp/uwsgi_params;
  }
}

如果我理解正确，上游的“家”不再由 uwsgi 提供服务，请尝试更改uwsgi_pass home;为proxy_pass home;
