KS添加nfs配置安装集群

一、安装前操作：

yum install -y nfs-utils # 或 apt install nfs-kernel-server
mkdir -p /KS
chmod 777 /KS

echo "/KS *(rw,no_root_squash,sync)" >> /etc/exports

systemctl enable --now nfs-server
exportfs -r

所有 K8s 节点安装 NFS 客户端
yum install -y nfs-utils
或
apt install -y nfs-common

测试是否能挂载（很关键）
在 node1 / node2 执行：
showmount -e 111.170.34.72

mount -t nfs 111.170.34.72:/KS /mnt
能挂载成功才说明 OK

二、KS安装自动安装NFS：
