First, build NFS
1. Execute command:sudo apt-get installnfs-kernel-server
2. Execute command:mkdir-p/opt/friendlyarm/mini210/linux/rootfs_mini210 Create a dedicated folder for NFS services

# chmod 777/opt/friendlyarm/mini210/linux/rootfs_mini210

3. After setting up the folder, execute the command:sudo vim/etc/exports Configure NFS
4. Add in the last line:

/opt/friendlyarm/mini210/linux/rootfs_mini210 * (Sync,rw,no_root_squash)

The meaning of this line is:

/OPT/FRIENDLYARM/MINI210/LINUX/ROOTFS_MINI210: Directory shared with the NFS service client, this path must match the path of the file you set up earlier!

*: Allow all network segments to be accessed or use specific IP

RW: Clients hooking up this directory have read and write access to the shared directory

Sync: Data is written to memory and hard disk synchronously

No_root_squash:root users have full administrative access to the root directory.

No_subtree_check: The permissions of the parent directory are not checked. More parameter Description I posted it under the article!

5. After modifying the above configuration file, save exit.

6. Execute the command:

Restart the Rpcbind service.

7. Execute the command :

#/etc/init.d/nfs-kernel-server Restart

Restart the NFS service.

# mkdir/mnt/nfs# Mount 192.168.1.101:/opt/friendlyarm/mini210/linux/rootfs_mini210/mnt/nfs# Ls/mnt/nfs
