1. 安装nfs工具，其实是mount需要mount.fs
否则会出现类似如下错误：
[root@stds ~]# mount -t nfs 192.168.7.1:/home/tong/Src /root/src
mount: wrong fs type, bad option, bad superblock on 192.168.7.1:/home/tong/Src,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program) In some cases useful info is found in syslog - try
dmesg | tail or so.
安装：
[root@stds ~]# yum install nfs-utils
2. 挂载：
[root@stds ~]# mount -t nfs 192.168.7.1:/home/tong/Src /root/src
[root@stds ~]# ls
anaconda-ks.cfg src
[root@stds ~]# ll src/
total

drwxr-xr-x. Dec : copyleft
drwxr-xr-x. Mar copyright
drwxr-xr-x. Oct : INSTALL
drwxr-xr-x. Dec : thirdparty
3. 开机自动挂载：
在 /etc/fstab 中，添加如下行
[root@stds ~]# tail -n1 /etc/fstab
192.168.7.1:/home/tong/Src /root/src nfs defaults,nofail,actimeo=
