Rabblimq
? AMQP，即Advanced Message Queuing Protocol，高级消息队列协议，是应用层协议的一个开放标准，为面向消息的中间件设计。
? 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的主要特征是面向消息、队列、路由（包括点对点和发布/订阅）、可靠性、安全。 RabbitMQ是一个开源的AMQP实现，服务器端用Erlang语言编写，支持多种客户端，如：Python、Ruby、.NET、Java、JMS、C、PHP、ActionScript、XMPP、STOMP等，支持AJAX。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。

yum install https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.7.5/rabbitmq-server-3.7.5-1.el7.noarch.rpm -y配置Rabbitmq(可选)
添加/etc/rabbitmq/rabbitmq-env.conf
RABBITMQ_NODENAME=rabbit@lek01启动
systemctl enable rabbitmq-server && systemctl start rabbitmq-server
rabbitmq-plugins enable rabbitmq_management #启动 web ui 插件命令参考
语法：rabbitmqctl -n <node> -l <command> [<command options>]
-n node
-q quiet
-t timeout
-l longnames默认 node "rabbit@server"，server为主机名称
虚拟主机默认是 ‘’‘/’
