Introduction
Welcome to this comprehensive guide on setting up an NFS server on Ubuntu. In today’s digitally-driven world, managing files and resources can become quite challenging, especially in a networked environment. NFS (Network File System) is a solution that simplifies sharing files and resources between networked computers. With NFS, you can share files between Linux and Unix systems in a transparent way, making it a powerful and useful tool for system administrators and developers alike. In this article, we will walk you through all the steps required to set up an NFS server on Ubuntu, including the installation of necessary packages, configuring the server, and mounting NFS shares. So, let’s get started!
What is NFS?
NFS (Network File System) is a distributed file system protocol that allows networked computers to share files and resources transparently. NFS enables users to access files on remote systems just as if they were available locally. It is an open-source protocol that was originally developed by Sun Microsystems. Today, NFS is widely used in Linux and Unix environments to share files and resources over the network. NFS works by using server-client architecture, where one server hosts the shared resources, and one or more clients access these resources. NFS is a powerful tool that simplifies file sharing and resource management in networked environments.
Why Setup NFS Server on Ubuntu?
Ubuntu is one of the most popular Linux distributions and is widely used in both personal and enterprise environments. Setting up an NFS server on Ubuntu can greatly simplify managing resources and sharing files between networked computers. NFS is a powerful tool that enables seamless file sharing between Linux and Unix systems, making it a must-have tool for system administrators and developers alike. By setting up an NFS server on Ubuntu, you can take advantage of this powerful protocol and simplify your resource management tasks.

Setting up NFS Server on Ubuntu
Step 1: Update Your System
Before installing any packages, it is always a good idea to update your system to the latest available packages. To do this, run the following command:
sudo apt-get update && sudo apt-get upgrade
This will update the package list and install any available updates on your system.
Step 2: Install NFS Server Packages
The next step is to install the NFS server packages. To do this, run the following command:
sudo apt-get install nfs-kernel-server
This will install the NFS server packages on your system.
Step 3: Configure NFS Server
The next step is to configure the NFS server. The configuration file for NFS server is located at /etc/exports. This file contains a list of directories that can be shared with other networked computers. To edit this file, run the following command:
sudo nano /etc/exports
This will open the /etc/exports file in the nano editor. You can add the directories that you want to share with other computers in this file.
For example, if you want to share the /mnt/nfs directory, you can add the following line to the /etc/exports file:
/mnt/nfs *(rw,sync,no_subtree_check)
Here, /mnt/nfs is the directory that you want to share with other computers. The * symbol means that any computer can access this directory. The rw option allows read and write access to the shared directory. The sync option ensures that changes made to the shared directory are immediately propagated to other computers. The no_subtree_check option disables subtree checking for this directory.
You can add multiple directories to the /etc/exports file, each on a new line.
Once you have made the necessary changes to the /etc/exports file, save and exit the nano editor.
Step 4: Export Directories
The next step is to export the directories that you have listed in the /etc/exports file. To do this, run the following command:
sudo exportfs -a
This will export all the directories listed in the /etc/exports file.
Step 5: Start NFS Server
The next step is to start the NFS server. To do this, run the following command:
sudo systemctl start nfs-kernel-server
This will start the NFS server on your system.
Step 6: Check NFS Server Status
The final step is to check the status of the NFS server to ensure that it is running without any issues. To check the status of the NFS server, run the following command:
sudo systemctl status nfs-kernel-server
This will show you the status of the NFS server, including any errors or warnings that may need to be addressed.
Advantages and Disadvantages of NFS Server on Ubuntu
Advantages
1. Simplifies Resource Management: NFS server simplifies the management of resources by allowing you to share files and resources between networked computers in a transparent way.
2. Easy to Use: NFS server is easy to use and configure, making it accessible to both novice and experienced users.
3. Open Source: NFS server is an open-source protocol, which means that it is freely available and can be modified to suit your specific needs.
4. Cross-Platform Support: NFS server supports both Linux and Unix systems, making it a powerful tool for sharing files and resources between different platforms.
Disadvantages
1. Security Concerns: NFS server is not secure by default, and additional security measures need to be taken to prevent unauthorized access to shared resources.
2. Performance Issues: NFS server can suffer from performance issues when sharing large files or when many clients are accessing the shared resources simultaneously.
3. Limited Network Range: NFS server is designed for use within a LAN (Local Area Network) and is not suitable for use over the internet or across WANs (Wide Area Networks).
4. Limited Features: NFS server has limited features compared to other file-sharing protocols and may not be suitable for all use cases.
