UBUNTU16.04NFS Configuration and ARM Development Board transfer Files _ mount and unload

Step One: Install NFS Services

sudo apt-get install nfs-kernel-server portmap

Step Two: Add NFS configuration Files

sudo vim /etc/exports

Add the following information to the VIM terminal:

/home/china/nfsroot *(rw,sync,no_root_squash)

The path above explains, for example, the shared folder where the Nfsroot folder is used for NFS services

Step Three: Restart the NFS service

sudo /etc/init.d/nfs-kernel-server restart

Each time you modify the configuration information for NFS, you need to execute a command to restart the NFS service
Done!!!

Verification one: Linux itself mounts itself

First, use the following command to view the Mount folder path information

showmount -e

Then execute the following command to mount the changed folder:

sudo mount -t nfs 192.168.1.218:/home/china/nfsroot /mnt/nfs/

Among them, the above IP address for my Ubuntu IP address, you can ipconfig view their own through the command, /mnt/nfs/ the NFS folder is my own in the Ubuntu system root/mnt/under the self-established.
Execute the following command to see if the mount succeeds

ls /mnt/nfs/

You can see /home/china/nfsroot/ that the information in the target folder is already attached to the /mnt/nfs/ folder.
Execute the following command to complete the uninstallation of the shared folder

sudo umount /mnt/nfs

Verification Two: The ARM board mounts the folders in the Linux system

Enter the ARM development Board (the author is Jz2440v3)
Execute the following command in the terminal of the Development Board

mount -t nfs -o nolock 192.168.1.218:/home/china/nfsroot /mnt/nfs/

The /mnt/nfs/ NFS folder in this is the one I built on the Development Board.
Execute commands in the terminal of the Development Board

ls /mnt/nfs/

Normal mount
The Unload Mounted Folder command is

 umount /mnt/nfs/

Verify that the uninstallation was successful.
P.S.
Each time you modify the configuration information for NFS, you need to execute a command to restart the NFS servicesudo /etc/init.d/nfs-kernel-server restart
If you encounter an error during execution, copy the problem to Baidu or Google, it may be solved
