Eureka-高可用

搭建俩个EurekaServer：eureka-server-1,eureka-server-2;然后相互注册，并取相同的应用名称

Server1

server:
  port: 8761
eureka:
  instance:
    hostname: eureka-server-1
  client:
    service-url:
      defaultZone: http://eureka-server-2:8762/eureka 
spring:
  application:
    name: eureka-server-ha

Server2 

server:
  port: 8762
eureka:
  instance:
    hostname: eureka-server-2
  client:
    service-url:
      defaultZone: http://eureka-server-1:8761/eureka
spring:
  application:
    name: eureka-server-ha

Client调用

eureka:
  instance:
    hostname: localhost
  client:
    service-url:
      defaultZone: http://eureka-server-1:8761/eureka,http://eureka-server-2:8762/eureka
