搭建Rabbitmq

写在前面：
1.服务器centos 7.8.2003版本
2.安装erlang参考博文A：https://www.cnblogs.com/fengyumeng/p/11133924.html
3.安装rabbitmq参考博文B（仅做参考，具体搭建还是看文档）：https://blog.csdn.net/jiang1986829/article/details/106090073

1.安装erlang完全用参考博文A，都能走完流程。（不再赘述）

1.参考博文B，安装socat。
2.参考博文B，安装public signing key。
3.安装rabbitmq-server（可能会出现找不到镜像的问题，多执行几次直到成功即可）

yum install -y rabbitmq-server

4.替换配置文件，如下图所示
根据不同系统设置不同的配置文件，文件名称（rabbitmq_erlang.repo），配置文件内容如下：

5.清除yum缓存

sudo yum clean all && sudo yum makecache

6.启动RabbitMQ服务

service rabbitmq-server start

7.状态查看

rabbitmqctl status

8.启用插件

rabbitmq-plugins enable rabbitmq_management

9.重启服务

service rabbitmq-server restart

10.添加帐号:name 密码:passwd

rabbitmqctl add_user name passwd

11.赋予其administrator角色

rabbitmqctl set_user_tags name administrator

12.设置权限（设置、读、写、操作）

rabbitmqctl set_permissions -p / name ".*" ".*" ".*"

13.其他操作命令参考博文B
