Configure NFS Server and Client on Linux Mint 20 - Step by Step process to do it ?

This article covers how to setup the NFS server and client on Mint. You will learn how to install the NFS server and client, configure and share NFS export directories, and mount/unmount the NFS shares on the client.

Network File System (NFS), is a distributed file system that allows various remote systems to access a file share. We all know that files should be stored on a central server for security and ease of backup. NFS provides us with a file sharing service that is easily managed and controls client access to resources.


To Install the NFS Client on the Client Systems:

1. Install the NFS-Common Package. As is the norm, begin by updating the system packages and repositories before anything else.

2. Create a NFS Mount Point on Client.

3. Mount NFS Share on Client System.

4. Testing the NFS Share on Client System.


A Network File System (NFS) allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. This enables system administrators to consolidate resources onto centralized servers on the network.


Benefits of setting up an NFS server:

1. Enables multiple computers to use the same files, so everyone on the network can access the same data.

2. Reduces storage costs by having computers share applications instead of needing local disk space for each user application.

Reboot Linux Mint 20 - How to do it ?

This article covers methods to reboot the Linux Mint. If you want to shut down your Linux Mint instead of rebooting, Learn How to Shutdown Linux Mint 20 .

Rebooting is the same as restarting, and close enough to powering off and then turning off your device. The purpose is to close and reopen the operating system. Resetting, on the other hand, means taking the device back to the state in which it left the factory. Resetting wipes all your personal data.


The systemctl command accepts, among many other options, halt (halts disk activity but does not cut power) reboot (halts disk activity and sends a reset signal to the motherboard) and poweroff (halts disk acitivity, and then cut power). These commands are mostly equivalent to starting the target file of the same name.


To reboot Linux:

1. To reboot the Linux system from a terminal session, sign in or "su"/"sudo" to the "root" account.

2. Then type " sudo reboot " to reboot the box.

3. Wait for some time and the Linux server will reboot itself.


To shut down Linux Mint:

Execute the following command:

sudo chmod u+s /sbin/shutdown

You will be prompted for your root password. After that, you're done and can type "exit" to exit out of the Terminal.


Linux Commands to Shutdown and Reboot the System:

1. Linux shutdown / reboot command. On Linux, like all tasks, the shutdown and restart operations can also be done from the command line.

2. "shutdown" command.

3. "reboot" command.

4. "halt" command.

5. "poweroff" command.
