安装nfs服务
如果用: apt-get install nfs-kernel-server portmap安装后会自动运行
打开/etc/exports文件，在末尾加入：
/ * 保存(注意/ * 之间有空格)
注:/etc/exports为NFS服务器的配置文件,"/ *"是挂载根目录下的所有文件
执行下面重启NFS服务
/etc/init.d/nfs-kernel-server restart
注：nfs允许挂载的目录及权限，在文件/etc/exports中进行定义，各字段含义如下：
/home/ *(rw,sync,no_root_squash)
/home/：要共享的目录
* ：允许所有的网段访问
rw ：读写权限
sync：资料同步写入内在和硬盘
no_root_squash：nfs客户端共享目录使用者权限
本机挂载测试
取消挂载
umount /mnt
linux内核配置
[*] Networking support ---> Networking options ---> [*] IP: kernel level autoconfiguration 當然還需要啟動NFS的功能。 File systems ---> [*] Network File Systems ---> <*> NFS client support [*] Root file system on NFS 5.3.2 網絡功能設置 TCP/IP 設置 要使能基本的網絡功能, 請依照以下設置即可. [*] Networking support ---> Networking options ---> <*> Packet socket <*> Unix domain sockets [*] TCP/IP networking [*] IP: multicasting
