先参照ETCD修改IP配置好ETCD服务，若Harbor仓库所在节点IP也有修改参照修改harbord服务所在机器的IP地址完成仓库配置
修改k8s主节点ip（在控制节点上替换所有节点的ip）
备份k8s的配置文件
cp -R /etc/kubernetes/ /etc/kubernetes-bak
配置新旧IP对应关系并在相应配置文件中进行替换
export oldip1=192.168.123.12 export newip1=192.168.1.12 export oldip2=192.168.123.13 export newip2=192.168.1.13 find /etc/kubernetes -type f | xargs sed -i "s/$oldip1/$newip1/" find /etc/kubernetes -type f | xargs sed -i "s/$oldip2/$newip2/" sed -i "s/$oldip1/$newip1/" /etc/systemd/system/kubelet.service.d/10-kubeadm.conf sed -i "s/$oldip2/$newip2/" /etc/systemd/system/kubelet.service.d/10-kubeadm.conf sed -i "s/$oldip1/$newip1/" /usr/local/bin/kube-scripts/initOS.sh sed -i "s/$oldip2/$newip2/" /usr/local/bin/kube-scripts/initOS.sh sed -i "s/$oldip1/$newip1/" /etc/kubernetes/kubeadm-config.yaml sed -i "s/$oldip2/$newip2/" /etc/kubernetes/kubeadm-config.yaml sed -i "s/$oldip1/$newip1/" /etc/hosts sed -i "s/$oldip2/$newip2/" /etc/hosts
删除包含旧IP的证书并重新生成新的证书
rm -f /etc/kubernetes/pki/apiserver* kubeadm init phase certs all --config /etc/kubernetes/kubeadm-config.yaml
进入k8s的配置文件夹，删除包含旧IP的配置文件并重新生成新的配置文件
cd /etc/kubernetes rm -f admin.conf kubelet.conf controller-manager.conf scheduler.conf kubeadm init phase kubeconfig all --config /etc/kubernetes/kubeadm-config.yaml cp /etc/kubernetes/admin.conf $HOME/.kube/config
重启服务，并查看服务状态
systemctl daemon-reload systemctl restart docker systemctl restart kubelet systemctl status kubelet
