1，故障现象查看状态存在不健康组件

[root@beian k8s]# kubectl get cs

Warning: v1 ComponentStatus is deprecated in v1.19+

NAME STATUS MESSAGE ERROR

controller-manager Unhealthy Get "http://127.0.0.1:10252/healthz": dial tcp 127.0.0.1:10252: connect: connection refused

scheduler Unhealthy Get "http://127.0.0.1:10251/healthz": dial tcp 127.0.0.1:10251: connect: connection refused

etcd-0 Healthy {"health":"true"}

2，解决办法

[root@beian k8s]# cd /etc/kubernetes/manifests/

[root@beian manifests]# ls

etcd.yaml kube-apiserver.yaml kube-controller-manager.yaml kube-scheduler.yaml

[root@beian manifests]# vim kube-controller-manager.yaml

[root@beian manifests]# vim kube-scheduler.yaml

以上两个文件注释掉

- --port=0

[root@beian manifests]# systemctl restart kubelet.service

[root@beian manifests]# kubectl get cs

Warning: v1 ComponentStatus is deprecated in v1.19+

NAME STATUS MESSAGE ERROR

controller-manager Healthy ok

scheduler Healthy ok

etcd-0 Healthy {"health":"true"}
