先记录一下，暂不完全
NFS服务，客户端需要安装 nfs-common，不然挂载时会出现下面错误
root@web1:~# mount -t nfs 192.168.2.202:/test /mnt/nfs
mount: wrong fs type, bad option, bad superblock on 192.168.2.202:/test,
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
#apt-get install nfs-common 即可解决
