服务端

1.安装软件包

yum install -y nfs-utils

2.写入共享目录

vim /etc/exports
/root/nfs_root/ *(insecure,rw,sync,no_root_squash)

3.启动共享服务

mkdir /root/nfs_root
systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server
exportfs -r

客户端

4.客户端 安装nfs工具包

yum install -y nfs-utils

5.检查主机共享目录

showmount -e $(nfs服务器的IP)
showmount -e 172.17.216.82

输出结果如下所示

Export list for 172.17.216.82:
/root/nfs_root *

6.挂在到本机

mkdir /home/map_data
mount -t nfs n1[:/home/map_data](http://0.0.0.51/home/map_data) /home/map_data
mkdir /root/nfsmount
# mount -t nfs $(nfs服务器的IP):/root/nfs_root /root/nfsmount

写入一个测试文件

echo "hello nfs server" > /root/nfsmount/test.txt
