题目要求：
• 共享/data/share目录；
• 用于存储server01主机的web数据；
• 仅允许service01主机访问该共享。
题目实施：
server01服务端配置：
安装nfs软件包：
[root@server01 ~]# yum -y install nfs-utils rpcbind
修改配置文件：
[root@server01 ~]# vim /etc/exports
#添加以下内容
/data/share 192.168.88.88/24(rw,sync,no_root_squash)
#方法二：
echo '/data/share 192.168.88.88/24(rw,sync,no_root_squash)' >> /etc/exports
#rw：可读写
#sync：同时将数据写入到内存与硬盘中，保证不丢失数据
#no_root_squash：无论 NFS 客户端使用什么用户访问，均映射为 NFS 服务器的 root 管理员
重启服务查看状态：
[root@server01 ~]# systemctl restart nfs-server
[root@server01 ~]# systemctl status nfs-server

关闭防火墙：
[root@server01 ~]# systemctl stop firewalld
查看nfs的文件共享：
[root@server01 ~]# showmount -e 192.168.88.88
Export list for 192.168.88.88:
/data/share 192.168.88.88/24
[root@server01 ~]# exportfs -v
/data/share 192.168.88.88/24(sync,wdelay,hide,no_subtree_check,sec=sys,rw,secure,no_root_squash,no_all_squash)
[root@server01 ~]# exportfs -arv
exporting 192.168.88.88/24:/data/share
exportfs: Failed to stat /data/share: No such file or directory
客户端配置：
安装nfs软件包：
[root@khd ~]# yum -y install nfs-utils rpcbind
配置永久挂载：
[root@khd ~]# mkdir /data/share -p
[root@khd ~]# echo '192.168.88.88:/data/share /data/share nfs defaults_netdev 0 0' >> /etc/fstab
[root@khd ~]# mount -a
查看挂载：
[root@khd ~]# df -h
