Redis实现了发布/订阅消息传递机制。
它的概念很简单:发布者在频道上发送消息。多个订户收到它。
订阅频道使用
SUBSCRIBE <channel>Publish to a channel using
PUBLISH <channel> <message>Example:
SUBSCRIBE dogs
In another redis-cli
window, type:
PUBLISH dogs "Roger"
Messages will be sent to the subscribers, and they’ll by default display the kind of event, the channel, and the message:

Subscribers can listen on multiple channels:
SUBSCRIBE dogs catsand will receive messages coming from all of them.
