Netflix Eureka和本地环境上的2个应用程序实例 [英] Netflix Eureka and 2 instances of application on local environment

问题描述

我开始使用Netflix Eureka并使用其1.1.145( https://github.com/Netflix/eureka/tree/1.1.145 )版本.

I'm getting started with Netflix Eureka and using its 1.1.145 (https://github.com/Netflix/eureka/tree/1.1.145) version.

我想在不同的端口上本地启动同一应用程序的2个实例，并将它们都注册到Eureka. 我正在使用示例服务(

I want to start locally 2 instances of the same application on different ports and have them both registered with Eureka. I'm using sample service (https://github.com/Netflix/eureka/blob/1.1.145/eureka-server/conf/sampleservice/sample-eureka-service.properties)

因此，我使用上述配置启动Eureka本身和2个实例-8001端口上的一个应用程序，以及8002端口上的另一个应用程序.

So I start Eureka itself and 2 instances using above config - one app on 8001 port and another on 8002.

由于某种原因，我在任何给定时间都只向Eureka注册一个实例.他们俩都毫无例外地开始了，可以和尤里卡(Eureka)交谈. 当我启动第二个实例时，似乎只是用自己的信息覆盖了有关第一个实例的信息.

For some reason I'm getting only one instance registered with Eureka at any given time. Both of them start without exceptions and can talk to Eureka OK. When I start a second instance, it seems to simply overwrite info about 1st instance with its own info.

我想要的是在 http://localhost的同一逻辑eureka.name下具有2个"instance"元素/eureka/v2/apps

我想念什么?

推荐答案

默认实例ID是主机名，因此要在同一主机上运行两个实例，您需要手动设置eureka.instance.metadataMap.instanceId(在还是要使用Spring Cloud应用程序.)

The default instance ID is the host name, so to run two of anything on the same host you need to manually set the eureka.instance.metadataMap.instanceId (that works in a Spring Cloud app anyway).
