Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems in 1984,
allowing a user on a client computer to access files over a computer network much like local storage is accessed.
Configure NFS Server
Install NFS server components
sudo apt-get install nfs-common nfs-server -y
Create the nfs server shared folder, you can use an existing folder as well
sudo mkdir /var/nfs
give the mount point you just created liberal permissions.
sudo chmod -R 777 /var/nfs
sudo service nfs-kernel-server stop
sudo service nfs-kernel-server start
Open the NFS exports file where you configure the paths to share and their permissions
sudo nano /etc/exports
Tell NFS to read your newly created exports file
