1.需要先下载elang

curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash

sudo yum install erlang-23.3.4.7-1.el7.x86_64

2.下载rabbitmq安装包

#下载文件
wget  https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.0/rabbitmq-server-3.8.0-1.el7.noarch.rpm
#导入key
https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.0/rabbitmq-server-3.8.0-1.el7.noarch.rpm
#yum本地安装
yum localinstall rabbitmq-server-3.8.0-1.el7.noarch.rpm

#启动
systemctl start rabbitmq-server

3.启动RabbitMQ后，没法访问Web管理页面
RabbitMQ安装后默认是不启动管理模块的，所以需要配置将管理模块启动
启动管理模块命令如下

rabbitmqctl start_app
rabbitmq-plugins enable rabbitmq_management
rabbitmqctl stop

验证
如果你是安装在本机器则访问http://localhost:15672/，发现可以访问Web管理页面了
4.增加远程访问账号密码

rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
