文章 史上最简单的 SpringCloud 教程 | 第一篇: 服务的注册与发现(Eureka) 介绍了服务注册与发现,其中服务注册中心Eureka Server,是一个实例,当成千上万个服务向它注册的时候,它的负载是很是高的,这在生产环境上是不太合适的,这篇文章主要介绍怎么将Eureka Server集群化。java
Eureka can be made even more resilient and available by running multiple instances and asking them to register with each other. In fact, this is the default behaviour, so all you need to do to make it work is add a valid serviceUrl to a peer, e.g.spring

Eureka经过运行多个实例,使其更具备高可用性。事实上,这是它默认的熟性,你须要作的就是给对等的实例一个合法的关联serviceurl。架构
这篇文章咱们基于第一篇文章的工程,来作修改。app
在eureka-server工程中resources文件夹下,建立配置文件application-peer1.yml:分布式
server: port: 8761 spring: profiles: peer1 eureka: instance: hostname: peer1 client: serviceUrl: defaultZone: http://peer2:8769/eureka/
而且建立另一个配置文件application-peer2.yml:微服务
server: port: 8769 spring: profiles: peer2 eureka: instance: hostname: peer2 client: serviceUrl: defaultZone: http://peer1:8761/eureka/
这时eureka-server就已经改造完毕。this
127.0.0.1 peer1 127.0.0.1 peer2
windows电脑,在c:/windows/systems/drivers/etc/hosts 修改。url
这时须要改造下service-hi:spa
eureka: client: serviceUrl: defaultZone: http://peer1:8761/eureka/ server: port: 8762 spring: application: name: service-hi
