rabbitMQ环境搭建

windows环境（单节点）

操作比较简单
1）先安装erlang工具：otp_win64_21.1.exe
2）安装rabbitMQ：rabbitmq-server-3.7.15.exe
3) 网页版http://localhost:15672输入账户(guest,guest)即可访问

CentOS环境（单节点）

依次执行以下步骤：

yum -y install docker
systemctl restart docker
vi /etc/docker/daemon.json
   {"registry-mirrors": ["https://r0mghv81.mirror.aliyuncs.com"]}
systemctl daemon-reload
systemctl restart docker

docker run -d --hostname localhost --name myrabbit -p 15672:15672 -p 5672:5672 rabbitmq:3.6.15-management

网页版http://ipAddress:15672输入账户(guest,guest)即可访问

Application.properties配置

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
