<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="" src="https://simg.open-open.com/show/19415a1a9b5dc387fd8324f77163bd3a.jpg" /></p> <h2>更新日志</h2> <h3>2个新插件</h3> <ul> <li> <p><a href="/misc/goto?guid=4958991593409488326">rabbitmq_trust_store</a> which manages<br /> trusted client x509/TLS certificates</p> </li> <li> <p><a href="/misc/goto?guid=4958991593498847468">rabbitmq_jms_topic_exchange</a> which, together with <a href="/misc/goto?guid=4958991847845523880">RabbitMQ JMS Java client</a>, provides support for the JMS 1.1 API<br /> atop RabbitMQ.</p> </li> </ul> <h3>Server</h3> <p>Bug修复</p> <ul> <li> <p>(Newly elected) queue master process could terminate immediately after promotion GitHub issue: <a href="/misc/goto?guid=4958991593673611683">rabbitmq-server#812</a></p> </li> <li> <p>Priority queue mirror could fail to synchronize after restart GitHub issues: <a href="/misc/goto?guid=4958991593762780868">rabbitmq-server#687</a>, <a href="/misc/goto?guid=4958991848040564527">rabbitmq-server#802</a></p> </li> <li> <p>Shutdown timeouts for worker processes are now much more reasonable.
