兄弟们，直接断电后，kubesphere启动不了了

Jeff

yuwengoku 兄弟啊，你先检查下防火墙是不是开了，主机ip是否变了，搜下帖子。服务器软件还是要提供一个稳定的环境，关机可以，开机之后状态至少要能恢复到关机之前的状态。

yuwengoku

Jeff 都检查过了没有问题，不知道为什么起不起来，没找到原因

yuwengoku

Jeff 我的网络用的是nat，固定ip，防火墙上来就关了

jcm

Jeff 大佬，主机ip变了后怎么启动呀

Jeff

yuwengoku 这个日志看着是 kube-apiserver 没有起来，docker ps -a | grep kube-apiserver 看下相关的container是否运行，如果有问题，可以用 docker logs 看下对应的container日志，先解决 kube-apiserver 的问题

Jeff

jcm 没办法，ip不能变。变了ip，证书那些都得重新生成，和重装没啥区别了

jcm

Jeff 我重装了一遍，现在重启后访问不了30880了。。

zackzhang

检查有没有异常pod

kubectl get po -A

观察日志

防火墙

kumu

zackzhang 我也遇到了，IP 没变就是起不来
开始有一台 etcd 没起来，把etcd 弄起来还是不想。
删除pod 就报这个异常
pod “kube-scheduler-hdss7-21.host.com” deleted
