kubernetes 报scheduler Unhealthy的错误解决

近来因项目需要，需使用k8s做相关的运维，因此通过sealos一键安装，在使用查看集群健康状态命令时

[root@k8s1 manifests]# kubectl get cs

报了下面的错误：

Warning: v1 ComponentStatus is deprecated in v1.19+
NAME                 STATUS      MESSAGE                                                                                       ERROR
scheduler            Unhealthy   Get "http://127.0.0.1:10251/healthz": dial tcp 127.0.0.1:10251: connect: connection refused   
controller-manager   Healthy     ok                                                                                            
etcd-0               Healthy     {"health":"true","reason":""} 

考虑到读者看代码块不方便，还是截取一张图片

进入 /etc/kubernetes/manifests路径

[root@k8s1 manifests]# cd /etc/kubernetes/manifests
ll
total 16
-rw------- 1 root root 2217 Dec 24 14:09 etcd.yaml
-rw------- 1 root root 3545 Dec 24 14:09 kube-apiserver.yaml
-rw------- 1 root root 3116 Dec 24 15:06 kube-controller-manager.yaml
-rw------- 1 root root 1648 Dec 24 15:05 kube-scheduler.yaml

分别修改kube-controller-manager.yaml和kube-scheduler.yaml文件

要是备份修改的话，一定要把备份的文件从当前目录剪切到其他目录，否则还是会报同样的错误。

[root@k8s1 manifests]# vim kube-scheduler.yaml

注释掉 --port=0

[root@k8s1 manifests]# vim kube-controller-manager.yaml

注释掉–port=0

重启服务

[root@k8s1 manifests]# systemctl restart kubelet
[root@k8s1 manifests]# kubectl get cs
