RabbitMQ v3.6.3 里程碑2 发布,AMQP消息服务器

   <p style="text-align:center"><img alt="" src="https://simg.open-open.com/show/03379414b3572debc448e04f087c61aa.jpg" /></p>    <p>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。</p>    <p>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。</p>    <p style="text-align:center"><img alt=""
