RabbitMQ是实现AMQP(高级消息队列协议)的消息中间件的一种,最初起源于金融系统,用于在分布式系统中存储转发消息,在易用性、扩展性、高可用性等方面表现不俗。消息中间件主要用于组件之间的解耦,消息的发送者无需知道消息使用者的存在,反之亦然。
AMQP 里主要要说两个组件:Exchange 和 Queue (在 AMQP 1.0 里还会有变动),如下图所示,绿色的 X 就是 Exchange ,红色的是 Queue ,这两者都在 Server 端,又称作 Broker ,这部分是 RabbitMQ 实现的,而蓝色的则是客户端,通常有 Producer 和 Consumer 两种类型。
Minimum required Erlang/OTP version is now 18.3. Recent Erlang versions can be obtained from Erlang Solutions or RabbitMQ Erlang RPM repository.
