一、容灾server集群

 

复制上例中的server项目两个,分别命名为x-server2和x-server3,修改yml配置

①端口:三个服务器的端口分别为9010,9011,9012

②defaultZone:三个服务器的defaultZone分别为对方,即排除自己之外的两个,即A填写BC的地址,B填写AC的地址,C填写AB的地址。

③name:修改三个server的name,做区分。

三个server的具体yml配置如下

server:
  port: 9010
  
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:9011/eureka/,http://localhost:9012/eureka/
  server:
    enable-self-preservation: false

spring:
  application: 
    name: eureka-server-9010
server:
  port: 9011
  
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:9010/eureka/,http://localhost:9012/eureka/
  server:
    enable-self-preservation: false

spring:
  application: 
    name: eureka-server-9011
server:
  port: 9012
  
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/
  server:
    enable-self-preservation: false

spring:
  application: 
    name: eureka-server-9012

 

为了演示配置用3台,两台即可,最好物理上做区分为2台。

 

二、eureka client集群

 

复制上例中的client项目两个,分别命名为x-client2和x-client3,修改yml配置

①端口:三个客户端的端口分别为9020,9021,9022

②defaultZone:三个客户端的defaultZone分别为三个server

③name:三个客户端分别修改name,做区分

三个客户端的yml配置如下:

server:
  port: 9020

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/,http://localhost:9012/eureka/
  
spring:
  application:
    name: eureka-client-9020
server:
  port: 9021

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/,http://localhost:9012/eureka/
  
spring:
  application:
    name: eureka-client-9021
server:
  port: 9022

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/,http://localhost:9012/eureka/
  
spring:
  application:
    name: eureka-client-9022

结果如下:

 可尝试关闭掉当前注册进的server,然后观察其他两个server的变化情况

 

以上!
