kubernetes 启动简单排错

#查看启动的服务
systemctl list-unit-files |grep kube

#依次查看服务情况
systemctl status kubelet


#查询各个服务的日志
journalctl -xefu kubelet

Mar 30 09:23:38 k8s-master1 kubelet[10310]: F0330 09:23:38.202074   10310 server.go:262] failed to run Kubelet: failed to create kubelet: failed to get docker version: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Mar 30 09:23:38 k8s-master1 systemd[1]: kubelet.service: main process exited, code=exited, status=255/n/a
Mar 30 09:23:38 k8s-master1 systemd[1]: Unit kubelet.service entered failed state.
Mar 30 09:23:38 k8s-master1 systemd[1]: kubelet.service failed.

以上信息可以发现docker没有启动。

重启docker
systemctl daemon-reload
systemctl restart docker
systemctl enable docker

#重启kubelet服务
systemctl restart kubelet.service
