Trying shared directory NFS PCs

In this article, we will discuss how to set up and run an NFS server on a PC and offer an NFS share. To start, we need to ensure that the NFS server is installed on the PC that will act as the server.

Install NFS server

On Ubuntu, open a terminal and run:

sudo apt-get install nfs-kernel-server

Configure NFS share

After installing the NFS server, we need to create a directory that will be shared and configure it in the /etc/exports file:

/path  (ro,sync,no_subtree_check)

Start NFS server

Finally, start the NFS server and enable it to start automatically at boot:

sudo systemctl start nfs-kernel-server
sudo systemctl enable nfs-kernel-server

Install the NFS server on the PC that will act as the server.
Create a directory that will be shared and configure it in the /etc/exports file.
Start the NFS server and enable it to start automatically at boot.
