왜 유레카는 마지막 갱신 시간이 이틀이 지났는데도 서비스가 여전히 'UP'이라고 생각합니다

Question

2 개의 복제본을 실행하는 서비스가 있습니다. 하지만 eureka의 대시 보드에 3 UP 인스턴스가있는 서비스를 발견했습니다.

아래에는 유레카의 서비스에 대한 세부 정보가 나와 있습니다. 문제가있는 인스턴스는 8d0c39f3ed9b : ocr-server : 8095이며 마지막 갱신 시간은 이틀 전입니다. 상태 및 상태 URL에 액세스 할 수 없습니다. 나는 유레카가 그것을 생각하는 이유를 궁금해!

유레카 클라이언트의 설정은 아래와 같이

eureka: 
    instance: 
    statusPageUrlPath: /info 
    healthCheckUrlPath: /health 
    preferIpAddress: false 
    client: 
    fetchRegistry: true 
    registryFetchIntervalSeconds: 5 
    healthcheck: 
     enabled: true 
    serviceUrl: 
     defaultZone: http://eureka-peer1:8761/eureka,http://eureka-peer2:8761/eureka 

유레카 서버의 구성은

,

eureka: 
    instance: 
    preferIpAddress: true 
    enableSelfPreservation: false 
    homePageUrl: http://${eureka.hostname}/ 
--- 
spring: 
    profiles: peer1 
eureka: 
    instance: 
    hostname: eureka-peer1 
    client: 
    serviceUrl: 
     defaultZone: http://eureka-peer2:${server.port}/eureka/ 

--- 
spring: 
    profiles: peer2 
eureka: 
    instance: 
    hostname: eureka-peer2 
    client: 
    serviceUrl: 
     defaultZone: http://eureka-peer1:${server.port}/eureka/ 

그리고 유레카 클라이언트와 서버가 모두 고정 표시기 떼에서 실행중인 보인다.

Answer 1

귀하의 서버가 아마도 자체 보존 모드에 들어갔 기 때문에 서버가 오래된 인스턴스를 볼 수 있습니다.

enableSelfPreservation: false 옵션이 있지만 오른쪽 섹션에 없으므로 eureka.server.enableSelfPreservation이어야하며 입력 한 내용이 eureka.instance.enableSelfPreservation이고 올바르지 않습니다.
