重启K8S服务
systemctl stop kubeletsystemctl stop kube-apiserversystemctl stop kube-proxysystemctl stop kube-controller-manager # 如果是master节点，需要执行systemctl stop kube-scheduler # 如果是master节点，需要执行systemctl stop flanneldsystemctl stop dockersystemctl restart iptablessystemctl start flanneldsystemctl start dockersystemctl start kubeletsystemctl start kube-apiserversystemctl start kube-proxysystemctl start kube-controller-manager # 如果是master节点，需要执行systemctl start kube-scheduler # 如果是master节点，需要执行systemctl status NetworkManager
查看kube-dns服务

重启harbor
cd /opt/install/harbordocker-compose downdocker-compose up -d #后台启动curl http://ip:80 #查看是否启动OK
harbor报502 Gate way错误
现在的解决办法是，不停的关闭，重启，直至OK
重装iptables
配置文件备份

卸载，然后重装
