重新初始化k8s master節點

卸載k8s, 可以參考這篇文章: https://blog.csdn.net/ccagy/article/details/85845979

 一共分為以下幾步:

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

rm -rf /etc/kubernetes/*
rm -rf ~/.kube/*
rm -rf /var/lib/etcd/*

 

4. 停用端口號, 把下面的這些端口號都停用就ok

lsof -i :6443|grep -v "PID"|awk '{print "kill -9",$2}'|sh

lsof -i :10259|grep -v "PID"|awk '{print "kill -9",$2}'|sh

lsof -i :10257|grep -v "PID"|awk '{print "kill -9",$2}'|sh

lsof -i :2379|grep -v "PID"|awk '{print "kill -9",$2}'|sh

lsof -i :2380|grep -v "PID"|awk '{print "kill -9",$2}'|sh
