【SpringCloud】Register-Server-注册中心（二）

Note

对应两条分支
springcloud-greenwich集成eureka + springboot2.1.x
springcloud-finchley集成consul + springboot2.0.x

注册中心可以说是微服务架构中的”通讯录“，它记录了服务和服务地址的映射关系。在分布式架构中，服务会注册到这里，当服务需要调用其它服务时，就到这里找到服务的地址，进行调用

Greenwich分支(Consul)

官网下载&安装

https://www.consul.io/

这里我开发环境在windows本机运行

在windows环境变量配置Path

D:\software\nodejs\;D:\dev\consul_1.5.2_windows_amd64;

启动Consul服务

默认端口为8500

consul agent -dev
