安装 NFS server
mystery@lcw:~$ sudo apt-get install nfs-kernel-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
<world>
mystery@lcw:~$
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
<world>
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/nfs
mystery@lcw:~$ ls /mnt/nfs/
mystery@lcw:~$
挂载NFS
mystery@lcw:~$ sudo mount 192.168.7.233:/home/mystery/nfs_files /mnt/nfs/ -t nfs
mystery@lcw:~$
测试下
mystery@lcw:~$ cd /mnt/nfs/
mystery@lcw:/mnt/nfs$ ls
mystery@lcw:/mnt/nfs$ touch test
mystery@lcw:/mnt/nfs$ ls
test
mystery@lcw:/mnt/nfs$ ls /home/mystery/nfs_files/
test
mystery@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$ ls
mystery@lcw:/mnt/nfs$
