Network File System (NFS) is a distributed filesystem protocol that allows clients to access remote files and directories as if they are available on the local system. This allows client systems to leverage large centrally shared storage. Users can access the same data from any system across the network. A typical setup for NFS includes a server that runs the NFS daemon, nfsd, and lists (export) files and directories to be shared. A client system can mount these exported directories as their local file system.
You will need two Ubuntu systems: one as a central NFS server and another as a client. The following is an example IP address configuration for the Host and Client systems:
Host - 192.168.2.14 Client - 192.168.2.16
Installing the Network File System
Follow these steps to install NFS:
Step 1 : First, we need to install the NFS server
sudo apt-get update sudo apt-get install nfs-kernel-server
Step 2 : Create the directories to be shared:
sudo mkdir /var/nfs
Step 3 : Add this directory to NFS exports under /etc/exports
sudo nano /etc/exports
Step 4 : Add the following line to /etc/exports
Step 5 : Save and close the exports file.
Step 6 : Now, restart the NFS service
sudo service nfs-kernel-server restart
Step 7 : Next, we need to configure the client system to access NFS shares.
Create a mount point for NFS shares
Step 1 : Install the nfs-common package on the client side
sudo apt-get install nfs-common sudo mkdir -p /var/nfsshare sudo chmod 777 /var/nfs
Step 2 : Mount the NFS shared directory on the newly-created mount point
sudo mount 192.168.2.14:/var/nfs /var/nfsshare
Step 3 : Confirm the mounted share with the following command:
mount -t nfs
Step 4 : Now, change the directory to /var/nfsshare, and you are ready to use NFS
