SpringCloud問題解決:spring-cloud-eureka啟動出錯Cannot execute request on any known server

null^發表於2018-04-02

場景:

  在啟動eureka server時,出現以下錯誤: 

com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

問題解決:

  檢視配置檔案application.yml,發現register-with-eureka 屬性值設定為true了,將其改為false,重啟eureka服務,啟動成功,問題解決

原因:

  在預設設定下,eureka服務註冊中心也會將自己作為客戶端來嘗試註冊它自己,所以我們需要禁用它的客戶端註冊行為:

eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false

總結:

  若是未禁用eureka服務註冊中心的客戶端註冊行為,需提供service-url註冊中心地址:

server:
  port: 8091
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: true
    fetch-registry: false
   #註冊中心地址
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
