# 命令查询所有用户列表
rabbitmqctl list_users
# 使用命令对 xiandian-admin 用户进行授权
set_permissions xiandian-admin ‘.*‘ ‘.*‘ ‘.*‘
# 查看队列信息,所包含的信息包括 name,arguments, messages,memory,将操作命令和返回结果以文本形式提交到答题框。

1.定位 linux 系统内存占用最高进程
(1)输入 top 指令
然后输入大写的 M(Shift+m),基于内存占用倒序,找到占用最大内存的进程,如果内存占用最大的为 beam.smp 则为 RabbitMQ 进程占用。
# 查看相应端口占用
netstat -lnutp |grep 15672
# rabbitmqctl status

/**生产者:发送成功后一定要关闭 connection,才不会产生临时队列,临时队列就是,如:amq.gen-7Z5nxW9MqSHllIS2QI6diQ
* 消费者:消费成成功后只要关闭channel
