和视频中操作一样，新建了application-eureka1.yml和application-eureka2.yml，然后用java -jar方式启动无法注册。

既然你是在本地测试的，那么配置中的ip应该是localhost，而不是服务名哦
看日志“Cannot execute request on any known server”，如果你先启动eureka1必然是会报错的，因为erueka2还未启动。只要应用启动起来就行，等eureka2启动了eureka1就不会报错了。
最后日志有“java.lang.IllegalStateException: Timer already cancelled.”这个是什么报错我也不太懂没遇到过。

DiscoveryClient_EUREKASERVER/192.168.31.63 - registration failed Cannot execute request on any known server 多看看错误吧，找不到eureka server，而且你这样贴代码，让看的人很痛苦
