开启某个插件：rabbitmq-plugins enable xxx

查看用户列表：rabbitmqctl list_users
添加用户:rabbitmqctl add_user admin admin
添加权限:rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
修改用户角色:rabbitmqctl set_user_tags admin administrator
修改用户密码:rabbitmqctl change_password username 'newpasswd'

重启服务：rabbitmq-server restart
关闭服务：rabbitmqctl stop
查看状态：rabbitmqctl status
