安裝nfs服務
如果用: apt-get install nfs-kernel-server portmap安裝後會自動運行
打開/etc/exports文件，在末尾加入：
/ * 保存(注意/ * 之間有空格)
注:/etc/exports爲NFS服務器的配置文件,"/ *"是掛載根目錄下的所有文件
執行下面重啓NFS服務
/etc/init.d/nfs-kernel-server restart
注：nfs允許掛載的目錄及權限，在文件/etc/exports中進行定義，各字段含義如下：
/home/ *(rw,sync,no_root_squash)
/home/：要共享的目錄
* ：允許所有的網段訪問
rw ：讀寫權限
sync：資料同步寫入內在和硬盤
no_root_squash：nfs客戶端共享目錄使用者權限
