RabbitMQ

通过官方脚本 - https://www.rabbitmq.com/download.html 安装RabbitMQ
安装完成查看接口只有5672和25672

--- 开启web和远程访问

[16:00:28 root@node1 ~]#rabbitmq-plugins enable rabbitmq_management
[16:00:28 root@node1 ~]#echo "loopback_users = none" > /etc/rabbitmq/rabbitmq.conf
[16:00:28 root@node1 ~]# systemctl restart rabbitmq-server.service

---5672是核心端口，15672是web程序，25672是集群，现在是单机模式
