• 服务提供者配置多注册中心，重启后，难道是降级策略？居然不能及时访问 2020-06-21 10:28:58.624 ERROR 98825 --- [et_127.0.0.1-14] c.n.e.cluster.ReplicationTaskProcessor : Network level connection to peer 127.0.0.1; retrying after delay
• Eureka不能保证服务的一致性，即服务提供者不保证所有注册中心都有配置信息

带来的问题：注册中心宕机，服务路由到其他注册中心后，由于缺配置仍然不可用。 解决办法：服务提供者配置多注册中心

• 服务提供者挂掉，服务不可用状态（单服务瓶颈） 2020-06-21 10:07:21.618 ERROR 4677 --- [tbeatExecutor-0] com.netflix.discovery.DiscoveryClient : DiscoveryClient_SPRING-EUREKA-PROVIDER/192.168.0.104:spring-eureka-provider:9000 - was unable to send heartbeat!

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

• 服务提供者仅配置台注册中心，服务会默认连接失败 2020-06-21 10:12:08.858 ERROR 5630 --- [nfoReplicator-0] c.n.d.s.t.d.RedirectingEurekaHttpClient : Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:8090/eureka/}
