eureka微服务注册之错误was unable to refresh its cache! status=Cannot execute request on any known server

问题

关键的问题描述就下面这2句来的，下面的图片应个景，我也看不懂

Request execution error. endpoint=DefaultEndpoint{serviceUrl='http://127.0.0.1:10086/eureka/},exception=java.net.ConnectException: Connection refused: connectstacktrace=com.sun.jersey.api.client.ClientHandlerException:java.net.ConnectException: Connection refused: connect

DiscoveryClient_EUREKASERVER/LAPTOP-GJ3QKVKK:eurekaserver:10086 - was unable to refresh its cache! This periodic background refresh will be retried in 30 seconds. status = Cannot execute request on any known server stacktrace = com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

解决

不出意外的话，你的eureka-server中的yml配置应该是如下图这么配的把，上图：

这就是为啥报错了，还得再加2个配置，话不多说，上图

这2个配置很关键哦，加上以后，你的报错应该解决了把，我的反正是解决了！

车修好了，springcloud继续学起来咯！
