rabbitmq集群的搭建 节点的删除、添加、更新 -- rabbitmq单机多节点的配置 监控 rabbitmq 通过3种方式实现分布式部署：集群、federation、shovel
rabbitmq-plugins enable rabbitmq_federation rabbitmq-plugins enable rabbitmq_federation_management
rabbitmq-plugins enable rabbitmq_shovel rabbitmq-plugins enable rabbitmq_shovel_management
集群种erlang和rabbitmq的版本要一致 shovel和federation的版本可以随意
