普通NFS共享的实现

准备需要共享的文件夹
1.[root@server0 ~]# mkdir /public
2.[root@server0 ~]# mkdir /protected

建立NFS共享配置
1.[root@server0 ~]# vim /etc/exports
2./public 172.25.0.0/24(ro)
3./protected 172.25.0.0/24(rw)

启动系统服务nfs-server，并设置开机自启
1.[root@server0 ~]# systemctl restart nfs-server
2.[root@server0 ~]# systemctl enable nfs-server
3.ln -s ‘/usr/lib/systemd/system/nfs-server.service’ ‘/etc/systemd/system/nfs.target.wants/nfs-server.service’

在desktop0上挂载NFS共享目录/public
创建挂载点
[root@desktop0 ~]# mkdir /mnt/nfsmount

列出server0上提供的NFS共享资源
1.[root@desktop0 ~]# showmount -e server0.example.com
2.Export list for server0.example.com:
3./protected 172.25.0.0/24
4./public 172.25.0.0/24

配置开机挂载server0的NFS共享目录/public
1.[root@desktop0 ~]# vim /etc/fstab
2… …
3.server0.example.com:/public /mnt/nfsmount nfs _netdev 0 0

测试挂载配置
1.[root@desktop0 ~]# mount -a
2.[root@desktop0 ~]# df -hT /mnt/nfsmount/
3.Filesystem Type Size Used Avail Use% Mounted on
4.server0.example.com:/public nfs4 10G 3.2G 6.8G 32% /mnt/nfsmount
