我们在目前的项目中使用Netflix，该项目将在几周内投入使用。上周之前一切都很好。服务在发现号中注册，网关能够将流量路由到所需的服务，门户运行良好。但是当在每个服务器上安装备份NIC卡时。当我重新启动服务时，服务将使用第二个nat IP地址(10.1.220.125)注册，而不是主机名(以前是)。我搜索了谷歌，发现了许多配置，但当我申请时，我并没有得到成功/预期的结果。其中一种配置如下：

代码语言：javascript
复制
spring:
  cloud:
    inetutils:
      ignoredInterfaces:
        - p2p.*

这是我的发现服务器的application.yml文件。

代码语言：javascript
复制
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，我看到发现服务正在注册，如下所示：

代码语言：javascript
复制
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。

以前，当只有一个nat IP (10.1.115.8)而没有备份IP时，我会在日志中获取消息：

代码语言：javascript
复制
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。

如何用主机名而不是IP注册我的服务？

我们正在使用Dalston.SR1版本的spring。

编辑:使用verion Greenwich.RC2

代码语言：javascript
复制
server:
  port: 8761

eureka:
  environment: prod
  client:
    registerWithEureka: true
    fetchRegistry: true
    healthcheck:
      enabled: true
    serviceUrl:
      defaultZone: http://10.1.115.8:8761/eureka/
  instance:
    registryFetchIntervalSeconds: 30
    leaseRenewalIntervalInSeconds: 10
    leaseExpirationDurationInSeconds: 30
    hostname: KOLSRV1
    ip-address: 10.1.115.8
    preferIpAddress: false
    #preferredNic: bond0
    #forceHostAddress: 10.1.115.8

zuul.sensitiveHeaders:

hystrix:
  command:
    default:
      execution:
        isolation:
          strategy: THREAD
          thread:
            timeoutInMilliseconds: 500000

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

我得到了以下错误：

代码语言：javascript

Request execution failed with message: A message body reader for Java class com.netflix.appinfo.InstanceInfo, and Java type class com.netflix.appinfo.InstanceInfo, and MIME media type text/html; charset=utf-8 was not found

供您参考，我将提供服务器的ifconfig详细信息。

@spencergib，我找到了解决办法。

在/etc/host文件中，我将条目放置如下：

代码语言：javascript
复制
KOLSRV1   10.1.220.125

现在，这些服务正在使用名称而不是IP在发现服务中注册。

代码语言：javascript
复制
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..
