还原k8s控制节点

0、基础环境配置

参照节点建立搭建配置

1、从旧控制节点拷贝

/opt/kubernets

/usr/local/bin/kubectl

/usr/lib/systemd/system/etcd.service

/usr/lib/systemd/system/kube-apiserver.service
/usr/lib/systemd/system/kube-controller-manager.service
/usr/lib/systemd/system/kubelet.service
/usr/lib/systemd/system/kube-proxy.service
/usr/lib/systemd/system/kube-scheduler.service

/root/.kube

/etc/kubernetes/admin.conf

/etc/hosts

 

2、修改IP地址

systemctl enable etcd --now

systemctl enable --now kube-apiserver.service kube-controller-manager.service kubelet.service kube-proxy.service kube-scheduler.service
