服务端：

1. yum install nfs*  

2. vim /etc/exports

   /www/attachment 192.168.0.227(rw,sync,no_root_sqush)

   启动服务

    service rpcbind start

    service nfs start

客户端

    1. yum install nfs*

    mount -t nfs 192.168.0.230:/www/attachment  /www/attachment

    启用服务

    service rpcbind start

客户端常见错误：

    1、客户端没有启用 rpcbind

    mount: wrong fs type, bad option, bad superblock on 192.168.0.230:/www/attachment,
       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

    2、 mount.nfs: access denied by server while mounting

        端口问题(具体疑问Google之)

        修正服务端/etc/exports

        /www/attachment 192.168.0.227(insecure,rw,sync,no_root_sqush)
