我正在使用带有django频道的Django。我要离开Andrew Godwins django频道的例子"MultiChat"的例子。我正在使用Webfaction和Putty来尝试让它运行，这是我得到的代码。
settings.py
redis_host = os.environ.get('REDIS_HOST', 'localhost')
CHANNEL_LAYERS = {
"default": {
# This example app uses the Redis channel layer implementation asgi_redis
"BACKEND": "asgi_redis.RedisChannelLayer",
"CONFIG": {
"hosts": [(redis_host, 27411)],
},
"ROUTING": "myproject.routing.channel_routing",
},
}
我确实在这里有一个问题，我会将它是否说本地主机更改为我的网站的 IP 地址，还是在使用 redis 时将其保留为本地主机？
至于我的索引.html我有这个 不确定是否需要调整或更新此代码，感谢任何帮助。

如果你的 redis 和你的 wepapp 在同一个地方，你可以localhost设置为 redis IP 地址。
- 你谈到了腻子，你在远程机器上吗？
- 您的 redis 是否正在侦听与定义到
settings相同的端口？
