第一種，手動刪除：
1. 刪除/etc/kubernetes/文件夾下的所有文件
2. 刪除$HOME/.kube文件夾
3. 刪除/var/lib/etcd文件夾
[root@k8s-master ~]# rm -rf /etc/kubernetes/*
[root@k8s-master ~]# rm -rf ~/.kube/*
[root@k8s-master ~]# rm -rf /var/lib/etcd/*
4、停用上圖所列的端口號
[root@k8s-master ~]# lsof -i :6443|grep -v "PID"|awk '{print "kill -9",$2}'|sh
[root@k8s-master ~]# lsof -i :10251|grep -v "PID"|awk '{print "kill -9",$2}'|sh
[root@k8s-master ~]# lsof -i :10252|grep -v "PID"|awk '{print "kill -9",$2}'|sh
[root@k8s-master ~]# lsof -i :10250|grep -v "PID"|awk '{print "kill -9",$2}'|sh
[root@k8s-master ~]# lsof -i :2379|grep -v "PID"|awk '{print "kill -9",$2}'|sh
[root@k8s-master ~]# lsof -i :2380|grep -v "PID"|awk '{print "kill -9",$2}'|sh
第二種，kubectl命令清除環境
[root@k8s-master ~]# kubectl reset
重新執行初始化命令
