暴露挂载点的机器：

yum -y install nfs-utils

mkdir -p /nfs/data/

chmod -R 777 /nfs/data

vim /etc/exports

写入以下内容：

/nfs/data *(rw,no_root_squash,sync)

生效配置并查看

exportfs -r
exportfs

启动服务：

systemctl restart rpcbind && systemctl enable rpcbind
systemctl restart nfs-server && systemctl enable nfs-server

其他需要进行挂载的机器：

yum -y install nfs-utils
systemctl start nfs rpcbind
systemctl enable nfs rpcbind

测试挂载：
showmount -e 192.168.1.2

直接挂载到本地查看：
mount 192.168.1.2:/nfs/data /opt

卸载挂载：
umount /opt

Pod 挂载使用：

apiVersion: v1
kind: Pod
metadata:
labels:
run: nginx
name: podxx
spec:
volumes:
- name: nfs
  nfs:
  server: 192.168.1.244
  path: /nfs/data
  containers:
- image: nginx
  name: nginx
  volumeMounts:
- mountPath: /usr/share/nginx/html
  name: nfs
