kubeadm安装k8s 组件controller-manager 和scheduler状态 Unhealthy

通过kubeadm安装好kubernetes v1.18.6 查看集群状态，发现组件controller-manager 和scheduler状态 Unhealthy

检查端口未监听

组件运行正常

检查kube-scheduler和kube-controller-manager组件配置是否禁用了非安全端口
vim /etc/kubernetes/manifests/kube-scheduler.yaml
vim /etc/kubernetes/manifests/kube-controller-manager.yaml

将port=0去掉
然后systemctl restart kubelet
再检查集群组件状态已正常
