Ubuntu 20.04 NFS Server: A Comprehensive Guide

Introduction

Greetings and welcome to this comprehensive guide on Ubuntu 20.04 NFS Server. In this article, we will delve into the world of network file sharing, specifically focusing on NFS (Network File System) server on Ubuntu 20.04. Whether you’re a seasoned system administrator or a beginner in the Linux world, this guide aims to provide valuable insights and information that will help you set up and configure NFS servers successfully.

What is an NFS Server?

Before diving deep into the world of Ubuntu 20.04 NFS Server, let’s first understand what an NFS server is. Network File System (NFS) is a distributed file system protocol that allows clients to access files and directories from a remote server over a network. It is widely used in Linux/Unix environments to share files between systems.

Why Ubuntu 20.04 NFS Server?

Ubuntu 20.04 is the latest Long Term Support (LTS) version, providing numerous advantages such as stability, security, and regular updates. NFS server is an essential component of a networked environment, and Ubuntu 20.04 offers great support for NFS server configuration and management.

Prerequisites

Before we proceed with the installation and configuration of Ubuntu 20.04 NFS Server, it’s essential to fulfill the following requirements:

Requirements	Description
Ubuntu 20.04 Server	A fresh installation of Ubuntu 20.04 Server
Static IP Address	Ensure that the server has a static IP address
Root Access	Root access or sudo privileges to install packages and modify system settings

Ubuntu 20.04 NFS Server Configuration

Step 1: Update and Upgrade Ubuntu 20.04

Before anything else, it’s essential to update and upgrade your Ubuntu 20.04 server to ensure that you have the latest packages and security patches. Open your terminal and run the following commands:

$ sudo apt update$ sudo apt upgrade

Step 2: Install NFS Server

Next, you need to install the NFS server package on your Ubuntu 20.04 server. Run the following command in your terminal:

$ sudo apt install nfs-kernel-server

Step 3: Configure NFS Exports

After successfully installing NFS server, you need to configure NFS exports. NFS exports define the directories that will be shared over the network. By default, NFS exports are stored in the /etc/exports file. Open your /etc/exports file using your favorite text editor:

$ sudo nano /etc/exports

Here, you can define the directories that you want to share and the client systems that can access them. For example:

/shared_folder client1(rw,sync,no_root_squash) client2(ro,sync,no_root_squash)

Here, /shared_folder is the directory that will be shared over the network, client1 and client2 are the client systems that can access it. “rw” and “ro” denote read-write and read-only access, respectively. “sync” ensures that changes are synchronized between the client and server while “no_root_squash” ensures that root on the client system has the same permissions as root on the NFS server.

Step 4: Export NFS Shares

After configuring NFS exports, you need to export the shares in /etc/exports. Run the following command in your terminal:

$ sudo exportfs -ra

Step 5: Configure Firewall

By default, NFS uses port 2049 for communication. You need to ensure that your firewall allows traffic on this port. Run the following commands in your terminal:

$ sudo ufw allow from any to any port 2049 proto tcp$ sudo ufw allow from any to any port 2049 proto udp

Step 6: Test NFS Connection

After completing the configuration on the NFS server, you can test the NFS connection from the client system. Run the following command in your terminal:

$ sudo mount -t nfs server_ip:/shared_folder /mnt

Here, server_ip is the IP address of the NFS server, /shared_folder is the NFS exported directory, and /mnt is the mount point on the client system where the shared folder will be mounted.

Ubuntu 20.04 supports NFSv2, NFSv3, and NFSv4.

Q8: Can multiple clients access the same NFS share simultaneously?

Yes, multiple clients can access the same NFS share simultaneously, provided that the share is configured to allow multiple connections.

Q9: Can NFS be used for sharing files between Linux and Windows?

Yes, NFS can be used for sharing files between Linux and Windows systems with the help of third-party software or NFS clients.

Q10: Can NFS be used on virtual machines?

Yes, NFS can be used on virtual machines, allowing virtual machines to share files with the host system or other virtual machines.

Q11: Can NFS be used for web server clusters?

Yes, NFS can be used for web server clusters, allowing multiple web servers to access the same files over a network.

Q12: Can NFS be used with Docker containers?
