希望搭建Eureka集群，配置三个实例却总有一台注册不上？

Question

下面是我的eureka配置信息： spring: application: name: eureka-server profiles: master server: port: 8001 eureka: instance: hostname: master lease-renewal-interval-in-seconds: 30 lease-expiration-duration-in-seconds: 30 prefer-ip-address: true client: serviceUrl: defaultZone: http://backup2:8003/eureka/, http://backup1:8002/eureka/ fetch-registry: true register-with-eureka: true --- spring: application: name: eureka-server profiles: backup1 server: port: 8002 eureka: instance: hostname: backup1 lease-renewal-interval-in-seconds: 30 lease-expiration-duration-in-seconds: 30 prefer-ip-address: true client: fetch-registry: true register-with-eureka: true serviceUrl: defaultZone: http://master:8001/eureka/, http://backup2:8003/eureka/ --- spring: application: name: eureka-server profiles: backup2 server: port: 8003 eureka: instance: lease-renewal-interval-in-seconds: 30 lease-expiration-duration-in-seconds: 30 hostname: backup2 prefer-ip-address: true client: fetch-registry: true register-with-eureka: true serviceUrl: defaultZone: http://master:8001/eureka/, http://backup1:8002/eureka/

Answer 1

经过尝试将以下两条配置去掉即可。

fetch-registry: true
register-with-eureka: true

Answer 2

hostname 有配置hosts文件吗？

Answer 3

eureka配置不是要每个上面写上集群所有节点么；
自己也要写上，三个节点都是：
client:

serviceUrl:
  defaultZone: http://master:8001/eureka/,http://backup2:8003/eureka/, http://backup1:8002/eureka/
