安装 NFS server

mystery@lcw:~$ sudo apt-get install nfs-kernel-server 

　　编辑/etc／exports，添加目标系统的根文件系统映射目录，假如目标系统的根文件系统最后映射到／home／mystery／nfs_files，则／etc／exports内容如下

/home/mystery/nfs_files *(subtree_check,rw,no_root_squash,async)    

　　解释如下：

• ／home／mystery／nfs_files：映射目录
• ＊：允许所以的主机挂载
• subtree_check：子目录权限检查
• rw：可读写
• no_root_squash：无root权限
• async：同步文件

重启服务

mystery@lcw:~$ sudo /etc/init.d/nfs-kernel-server restart * Stopping NFS kernel daemon   ...done. * Unexporting directories for NFS kernel daemon...   ...done. * Exporting directories for NFS kernel daemon...exportfs: Failed to stat /home/mystery/nfs_files: No such file or directory   ...done. * Starting NFS kernel daemon   ...done.mystery@lcw:~$ sudo exportfs/home/mystery/nfs_files                
     
      mystery@lcw:~$
     

 　　最好每修改过 ／etc／exports 后都执行一次

测试NFS

　　首先建立一个nfs测试的挂载点

mystery@lcw:~$ sudo mkdir /mnt/nfsmystery@lcw:~$ ls /mnt/nfs/mystery@lcw:~$  

　　挂载NFS 

mystery@lcw:~$ sudo mount 192.168.7.233:/home/mystery/nfs_files /mnt/nfs/ -t nfsmystery@lcw:~$  

　　测试下 

mystery@lcw:~$ cd /mnt/nfs/mystery@lcw:/mnt/nfs$ lsmystery@lcw:/mnt/nfs$ touch testmystery@lcw:/mnt/nfs$ lstestmystery@lcw:/mnt/nfs$ ls /home/mystery/nfs_files/testmystery@lcw:/mnt/nfs$

 　　OK，卸载

mystery@lcw:/mnt/nfs$ cd ..mystery@lcw:/mnt$ sudo umount ./nfs/mystery@lcw:/mnt$ cd nfs/mystery@lcw:/mnt/nfs$ lsmystery@lcw:/mnt/nfs$
