关于两台独立主机部署eureka高可用的问题！

@hurukawatinami 您好，将peer1注册到peer2，peer2注册到peer1即可。
您在两台机器无法成功注册，考虑是网络问题，例如A机器不知道B的主机名。可以去掉主机名(hostname)配置，直接用IP。

@eacdy 我试过用ip地址，不行。

两个独立的eureka地址分别是：

http://192.168.159.211:7021
http://192.168.159.212:7022

下面是eureka的yml配置文件：

server:
  port: 7021
spring:
  profiles: test-211
eureka:
  instance:
    hostname: discovery-211        #Eureka实例的主机名
    prefer-ip-address: true
    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}
  client:
    serviceUrl:
      defaultZone: http://192.168.159.212:7022/eureka/  #Eureka节点相互注册
      register-with-eureka: true

server:
  port: 7022
spring:
  profiles: test-212
eureka:
  instance:
    hostname: discovery-212        #Eureka实例的主机名
    prefer-ip-address: true
    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}
  client:
    serviceUrl:
      defaultZone: http://192.168.159.211:7021/eureka/  #Eureka节点相互注册
      register-with-eureka: true

我的意思是 你在192.168.159.211 机器上ping discovery-212 看能不能通；在192.168.159.212 上ping下ping discovery-211能不能通；如果不能通，要么配置主机名，让它能ping通，要么就直接改成：

    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}

      defaultZone: http://192.168.159.211:7021/eureka/  #Eureka节点相互注册
      register-with-eureka: true

或者简写：

eureka:
  instance:
    prefer-ip-address: true
    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}
  client:
    serviceUrl:
      defaultZone: http://192.168.159.212:7022/eureka/,http://192.168.159.211:7021/eureka/
