在nginx后面使用Daphne

Question

我有一个Django应用程序，它将uWSGI与Nginx一起用于生产部署。现在，我正在集成通道2.0，并意识到Daphne是这里的uwsgi的替代品。我可以让Daphne在独立模式下运行它，但是当我试图在nginx代理之后运行它时，我总是得到连接超时(504)。

我的nginx文件是我为uWSGI服务器配置的文件，我希望它只运行otb，因为套接字名称是相同的。

可能出现的问题

• 从nginx日志中的情况来看，nginx试图连接到uwsgi://unix:///path/to/nginx.sock，但我认为它不应该以uwsgi作为前缀，而应该是unix:///path/to/nginx.sock。

后续问题

• 是否建议将Daphne同时用于服务器http和websocket？或者，我应该只为websockets使用uWSGI用于http和Daphne。
• 如果两者都使用Daphne，我是否正确地保留了相同的uwsgi_params文件？

Daphne服务器记录

如果我的理解正确，上游的“家”不再由uwsgi提供服务，请尝试将uwsgi_pass home;改为proxy_pass home;。
