How to Install and Configure NFS on Ubuntu

NFS, which stands for Network File System, is a tool that lets you share files over a network. Having a folder on one computer that others can open, edit, and save files to, just like it’s on their own machine. For Ubuntu users, NFS is particularly useful. It means you can have one central spot for all your files, which anyone on your network can use without needing to transfer files back and forth.

This setup is perfect for groups working on projects or for anyone who wants easy access to shared resources. It simplifies file management, reduces clutter, and speeds up collaborative work. This article will guide you through how to setup NFS on Ubuntu system, turning it into a file-sharing hub for your network.

Installing NFS Server

Before diving into the Ubuntu NFS server installation, ensure your system’s package list is up to date and all installed software is at the latest version:

sudo apt update && sudo apt upgrade -y
update and upgrade
  • sudo apt update: updates the package index to ensure you have access to the latest package versions.
  • sudo apt upgrade -y: upgrades all installed packages to their latest versions. The `-y` flag automatically answers ‘yes’ to any prompts, streamlining the process.

Next, install NFS server Ubuntu package:

sudo apt install nfs-kernel-server
nfs kernel server

Purpose: This command installs the necessary software to run an NFS server on your Ubuntu machine.

Create the Directory to Share

Create a directory specifically for NFS sharing:

sudo mkdir /var/nfs/share -p
nfs share
  • mkdir makes a new directory: The -p flag ensures no error is thrown if the directory already exists, and it creates parent directories as needed.

Adjust the ownership and permissions:

sudo chown nobody:nogroup /var/nfs/share && sudo chmod 777 /var/nfs/share
nobody group
  • chown nobody:nogroup changes the directory ownership to nobody and nogroup, which is a security best practice for NFS shares to prevent unauthorized access.
  • chmod 777 gives read, write, and execute permissions to everyone. This is risky in production environments; consider more restrictive permissions.

Configure NFS Exports

Edit the NFS export file to define access:

sudo nano /etc/exports
etc exports

nano is a simple text editor. Here, you define which directories are shared and with what permissions.

Add your share configuration:

sudo /var/nfs/share 192.168.1.0/24(rw,sync,no_subtree_check)
nfs share check

This line specifies that the /var/nfs/share directory is shared with the network 192.168.1.0/24, allowing read/write (rw) access, using synchronous writes (sync), and disabling subtree checking for performance.

Apply the export settings:

sudo exportfs -a
exportfs -a

exportfs -a exports all directories listed in /etc/exports, making them available to clients.

Start and Enable NFS Server

To ensure the NFS server runs:

sudo systemctl start nfs-server && sudo systemctl enable nfs-server && sudo systemctl status nfs-server
nfs server systemctl
  • start begins the service immediately.
  • enable ensures the service starts on system boot.
  • status checks if the service is running correctly.

Firewall Configuration

If you have install UFW on Ubuntu system, configure it to allow NFS traffic:

sudo ufw allow from 192.168.1.0/24 to any port nfs && sudo ufw enable && sudo ufw status
ufw setup

Client Configuration

On your client machine, install the NFS client:

sudo apt install nfs-common
nfs common

Purpose: Install client utilities needed to mount NFS shares.

Mount the NFS share:

sudo mount server_IP:/var/nfs/share /mnt

This command mounts the shared directory from the server to the local /mnt directory.

For a persistent mount:

echo 'server_IP:/var/nfs/share /mnt nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0' | sudo tee -a /etc/fstab
server IP

Adds an entry to /etc/fstab for automatic mounting at boot. The options ensure the system doesn’t hang if the NFS server is down (nofail), optimizes performance, and handles file locking.

What is NFS?

NFS, or Network File System, is a distributed file system protocol that allows files to be shared across a network. It enables users to access and share files on remote systems as if they were local.

NFS is built on the concept of a client-server architecture, where the server hosts the shared files and the clients access them through the network. NFS is a valuable tool for collaborative work, simplifying file management and reducing clutter. It is widely used in various environments, including office networks, data centers, and cloud computing platforms.

Why Do We Need NFS?

NFS is essential for several reasons:

  • Collaboration: NFS enables teams to work together on projects seamlessly, sharing files and resources without the need for manual transfers.
  • Centralized File Management: NFS creates a central hub for files, making it easier to manage and maintain access control.
  • Scalability: NFS allows you to expand your storage capacity without the need for additional hardware on individual machines.
  • Convenience: NFS simplifies file access, reducing the need for manual file transfers and version control.

Benefits of NFS

The benefits of using NFS include:

  1. Improved Collaboration: NFS facilitates teamwork by providing a shared workspace for files and resources.
  2. Increased Productivity: With NFS, users can access files quickly and easily, reducing downtime and increasing productivity.
  3. Simplified File Management: NFS streamlines file management, reducing clutter and making it easier to maintain access control.
  4. Cost-Effective: NFS is a cost-effective solution, eliminating the need for additional hardware and reducing the complexity of file management.

Conclusion

By following this guide, you’ve learned how to implement NFS on your Ubuntu server. We started with the basics: updating your system, installing the NFS server, and creating a shareable directory. We configured access rights, ensuring only the right people can get to your files, and set up the firewall to keep everything secure.

We also covered how to connect client machines to this shared space. Now, your Ubuntu server is not just a computer; it’s a central file repository that enhances teamwork by providing seamless file access. With NFS configured, you’ve streamlined how files are shared and accessed across your network, making data management both easier and more efficient. Remember, while NFS boosts convenience, always keep an eye on security and performance tweaks to match your specific needs.

Installing NFS on Ubuntu can be a simple process. Upgrading to an Ultahost Linux VPS server provides a more powerful and affordable environment to configure the NFS setup. These VPS plans offer processing power, RAM, and storage, ensuring smooth performance.
