可以mount本地一个目录到另外一个目录，以便提供NFS
mount --bind /home/bigdir /mnt/nfsdir
fstab 中加入如下内容，以便开机启动挂载
/mnt/nfsdir /home/bigdir none rw,bind 0 0
/etc/exports中加入如下内容，以便导出NFS列表
/mnt/nfsdir 192.168.0.1/24(rw,sync,no_root_squash)
192.168.0.1/24 指192.168.0.x网段可访问，也可指定固定IP地址
ro 只读访问
rw 读写访问
sync 所有数据在请求时写入共享
async NFS在写入数据前可以相应请求
secure NFS通过1024以下的安全TCP/IP端口发送
insecure NFS通过1024以上的端口发送
wdelay 如果多个用户要写入NFS目录，则归组写入（默认）
no_wdelay 如果多个用户要写入NFS目录，则立即写入，当使用async时，无需此设置。
hide 在NFS共享目录中不共享其子目录
no_hide 共享NFS目录的子目录
subtree_check 如果共享/usr/bin之类的子目录时，强制NFS检查父目录的权限（默认）
no_subtree_check 和上面相对，不检查父目录权限
all_squash 共享文件的UID和GID映射匿名用户anonymous，适合公用目录。
no_all_squash 保留共享文件的UID和GID（默认）
root_squash root用户的所有请求映射成如anonymous用户一样的权限（默认）
no_root_squas root用户具有根目录的完全管理访问权限
anonuid=xxx 指定NFS服务器/etc/passwd文件中匿名用户的UID
客户机/etc/fstab加入如下内容，以便启动自动挂载
ServerA:/mnt/nfsdir /mnt/nfsdir nfs rw,timeo=300,retrans=5,hard,intr,bg,suid
其中，
ServerA - NFS 服务器的计算机名
rw - 读和写访问
timeo=300 - 如果 nfs 服务器在规定时间内没有响应（以十分之一秒为单位），则允许内核超时
retrans=5 - 设置在返回错误之前重复的请求数
hard - 当服务器挂起时，客户机将被阻塞，直到服务器重新处于活动状态
intr - 客户机（用户）可以中断会导致错误的被阻塞的操作
bg - 如果装配失败，系统继续在后台重试，然后继续
suid - 允许 set-user-identifier 或 set-group-identifier 生效
