eureka报错：链接8761被拒绝

eureka报错：链接8761被拒绝

来龙去脉

在idea环境中运行没有问题

我的配置是：

server:

  port: 8001

spring:

  application:

    name: registry-server

eureka:

  instance:

    hostname: localhost

  client:

    fetch-registry: false

    register-with-eureka: false

微服务部署后，eureka服务会不断报上面的错误

 org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: 拒绝连接

连接http://localhost:8761/eureka 的注册中心被拒绝，无法连接

可是我已经改了端口为8001

即时只启动eureka服务仍然报错，但是报错又不影响客户端的注册和发现

部署后的配置：

server:

  port: 8001

spring:

  application:

    name: eureka-server

eureka:

  instance:

    hostname: 192.168.110.157

  client:

    fetch-registry: false

    register-with-eureka: false

原因分析

8761 是Eureka的默认路径, Eureka认为启动配置里没有对它的url地址指定时, 会默认寻找这个地址

解决办法

用defaultZone配置注册中心地址

server:

  port: 8001

spring:

  application:

    name: eureka-server

eureka:

  instance:

    hostname: 192.168.110.157

  client:

    fetch-registry: false

    register-with-eureka: false

    service-url:

      defaultZone: http://localhost:8001/eureka/
