文章 史上最簡單的 SpringCloud 教程 | 第一篇: 服務的註冊與發現(Eureka) 介紹了服務註冊與發現,其中服務註冊中心Eureka Server,是一個實例,當成千上萬個服務向它註冊的時候,它的負載是很是高的,這在生產環境上是不太合適的,這篇文章主要介紹怎麼將Eureka Server集羣化。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經過運行多個實例,使其更具備高可用性。事實上,這是它默認的熟性,你須要作的就是給對等的實例一個合法的關聯serviceurl。架構
這篇文章咱們基於第一篇文章的工程,來作修改。app
在eureka-server工程中resources文件夾下,建立配置文件application-peer1.yml:分佈式
server: port: 8761 spring: profiles: peer1 eureka: instance: hostname: peer1 client: serviceUrl: defaultZone: http://peer2:8769/eureka/
而且建立另一個配置文件application-peer2.yml:微服務
server: port: 8769 spring: profiles: peer2 eureka: instance: hostname: peer2 client: serviceUrl: defaultZone: http://peer1:8761/eureka/
這時eureka-server就已經改造完畢。this
127.0.0.1 peer1 127.0.0.1 peer2
windows電腦,在c:/windows/systems/drivers/etc/hosts 修改。url
這時須要改造下service-hi:spa
eureka: client: serviceUrl: defaultZone: http://peer1:8761/eureka/ server: port: 8762 spring: application: name: service-hi
架構代碼以下:
