错误：
[root@localhost]# mount -t nfs 192.168.0.106:/home/nfs1 /home/nfs
mount: wrong fs type, bad option, bad superblock on 192.168.0.106:/home/nfs1,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog – try
dmesg | tail or so
解决办法：
1 apt-get install nfs-common
或者
1 yum install nfs-utils
