<p style="text-align: center;"><strong><img alt="" src="https://simg.open-open.com/show/03379414b3572debc448e04f087c61aa.jpg" /></strong></p> <p> </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;"><a href="https://simg.open-open.com/show/19415a1a9b5dc387fd8324f77163bd3a.jpg"><img alt="" src="https://simg.open-open.com/show/19415a1a9b5dc387fd8324f77163bd3a.jpg" /></a></p> <p> </p> <h2>更新日志</h2> <h3>Bug 修复</h3> <ul> <li>Changing queue mode to <code>lazy</code> could block queue process in certain circumstances.</li> <li>GitHub issue: <a href="/misc/goto?guid=4958993444899505199">rabbitmq-server#850</a></li> <li>Mirroring implementation didn't handle certain internal protocol messages arriving out of order.</li> <li>GitHub issue: <a href="/misc/goto?guid=4958993445028897419">rabbitmq-server#922</a></li> <li>Mirror set changes weren't handled gracefully in certain circumstances (e.g. in the middle of a mirror promotion).</li> <li>GitHub issue: <a href="/misc/goto?guid=4958993445140193427">rabbitmq-server#914</a></li> <li>Mirrored queue could terminate after promotion if HA policy was reapplied during sync </li> <li>GitHub issue: <a href="/misc/goto?guid=4958993641879498995">rabbitmq-server#803</a></li> <li>Autoheal partition handling mode could run into a multi-node deadlock</li> <li>GitHub issue: <a href="/misc/goto?guid=4958993641989021707">rabbitmq-server/issues/928</a></li> <li>Queue mirror group membership now correctly handles certain partial partition cases.</li> <li>GitHub issues: <a href="/misc/goto?guid=4958994323261515010">rabbitmq-server#950</a>,</li> <li><a href="/misc/goto?guid=4958994323364367946">rabbitmq-server#953</a></li> <li>Eager queue sync will now stop as soon as a mirror shutdown/unavailability is detected.</li> <li>GitHub issue: <a href="/misc/goto?guid=4958994323454783606">rabbitmq-server#975</a></li> <li>Lazy queues now trigger runtime GC significantly less frequently, making moving data to the message store more efficient.</li> <li>GitHub issue: <a href="/misc/goto?guid=4958994323545656651">rabbitmq-server#973</a></li> <li><code>rabbitmqctl</code> and server startup could be affected by some DNS configurations.</li> <li>GitHub issue: <a href="/misc/goto?guid=4958993445280395681">rabbitmq-server#890</a></li> <li>RPM package was split into two: for CentOS 6 and 7.
