我正在尝试第一次使用Django频道，我正在遵循文档中的教程。但是当我使用python manage.py runserver并尝试连接时，出现此错误。
Protocol error, got "H" as reply type byte
这是整个控制台（我正在使用anaconda）：
Quit the server with CTRL-BREAK.

运行django服务器时，您是否有机会在计算机上没有运行Redis服务器？在Mac上，我先执行brew install redis，然后执行redis-server，然后在另一个终端窗口上运行django服务器，一切正常。
答案 1 :(得分：0)
在我的情况下，我使用Nginx转发Redis请求，这导致访问Redis的协议出现问题。因此，我关闭了Nginx的转发，并使用rinetd转发了此请求，以检查您的应用程序和Redis之间的最后一个通信协议是否正确

有同样的问题，我为 REDIS 连接使用了错误的端口。
我给了它 MySql 端口（可用且正在侦听），所以它不会显示为连接失败，而是显示为协议错误。
