在发现服务中注册多个 IP

Question

我们正在我们当前的项目中使用 Netflix OSS，该项目将在几周内上线。一切都很好，直到上周。服务在发现中注册，网关能够将流量路由到所需的服务，门户工作正常。但是当每台服务器都安装了备份网卡时。当我重新启动服务时，服务正在使用第二个 nat IP 地址（10.1.220.125）而不是主机名（以前是）注册。我搜索了 google 并找到了很多配置，但是当我申请时我没有得到 successful/expected 结果。一种这样的配置如下：

spring:
  cloud:
    inetutils:
      ignoredInterfaces:
        - p2p.*

这是我的 application.yml 发现服务器文件。

spring:
  application:
    name: discovery-service
server:
  port: 8761

eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    healthcheck:
      enabled: true
    serviceUrl:
      defaultZone: http://10.1.115.8:8761/eureka/
  instance:
    registryFetchIntervalSeconds: 30
    leaseRenewalIntervalInSeconds: 10
    leaseExpirationDurationInSeconds: 30

zuul.sensitiveHeaders:

hystrix:
  command:
    default:
      execution:
        isolation:
          strategy: THREAD
          thread:
            timeoutInMilliseconds: 500000
spring:
  cloud:
    inetutils:
      ignoredInterfaces:
        - p2p.*

当我看到日志时，我看到正在注册发现服务，如下所示：

Registered instance DISCOVERY-SERVICE/10.1.220.125:discovery-service:8761 with status UP (replication=false)
DiscoveryClient_DISCOVERY-SERVICE/10.1.220.125:discovery-service:8761 - registration status: 204
Registered instance DISCOVERY-SERVICE/10.1.220.125:discovery-service:8761 with status UP (replication=true)

其中 10.1.220.125 是新的 nat IP。

之前我曾经在只有一个nat IP（10.1.115.8）并且没有备份IP的情况下在日志中获取消息：

Registered instance DISCOVERY-SERVICE/KOLSRV1:discovery-service:8761 with status UP (replication=false)
DiscoveryClient_DISCOVERY-SERVICE/KOLSRV1:discovery-service:8761 - registration status: 204
Registered instance DISCOVERY-SERVICE/KOLSRV1:discovery-service:8761 with status UP (replication=true)

其中 KOLSRV1 是具有 IP 10.1.115.8 和 10.1.220.125 的服务器主机名。

如何使用主机名而不是 IP 注册我的服务？

我们正在使用 spring 云的 Dalston.SR1 版本。

我收到以下错误：

为了您的参考，我提供了服务器的 ifconfig 详细信息。

Answer 1

@spencergib，我找到了解决方案。

在 /etc/hosts 文件中，我输入了

KOLSRV1   10.1.220.125

现在服务正在使用名称而不是 IP 在发现服务中注册。

Registered instance DISCOVERY-SERVICE/KOLSRV1:discovery-service:8761 with status UP (replication=false)
DiscoveryClient_DISCOVERY-SERVICE/KOLSRV1:discovery-service:8761 - registration status: 204
Registered instance DISCOVERY-SERVICE/KOLSRV1:discovery-service:8761 with status UP (replication=true)

谢谢..

在发现服务中注册多个 IP
