Installing and configuring NFS Server on Ubuntu

To install and configure the NFS server, follow the steps outlined below.

Step 1: Install NFS Kernel Server in Ubuntu

The first step is to install the nfs-kernel-server package on the server. But before we do this, let’s first update the system packages using the following apt command.

$ sudo apt update

Once the update is complete, proceed and install the nfs-kernel-server package as shown below. This will store additional packages such as nfs-common and rpcbind which are equally crucial to the setup of the file share.

$ sudo apt install nfs-kernel-server

Step 2: Create an NFS Export Directory

The second step will be creating a directory that will be shared among client systems. This is also referred to as the export directory and it’s in this directory that we shall later create files which will be accessible by client systems.

Run the command below by specifying the NFS mount directory name.

$ sudo mkdir -p /mnt/nfs_share

Since we want all the client machines to access the shared directory, remove any restrictions in the directory permissions.

$ sudo chown -R nobody:nogroup /mnt/nfs_share/

You can also tweak the file permissions to your preference. Here’s we have given the read, write and execute privileges to all the contents inside the directory.

$ sudo chmod 777 /mnt/nfs_share/

Create NFS Share in Ubuntu

Step 3: Grant NFS Share Access to Client Systems

Permissions for accessing the NFS server are defined in the /etc/exports file. So open the file using your favorite text editor:

$ sudo vim /etc/exports

You can provide access to a single client, multiple clients or specify an entire subnet.

In this guide, we have allowed en entire subnet to have access to the NFS share.


Explanation about the options used in the above command.

§  rw: Stands for Read/Write.

§  sync: Requires changes to be written to the disk before they are applied.

§  No_subtree_check: Eliminates subtree checking.

Set NFS Share Access

To grant access to a single client, use the syntax:

/mnt/nfs_share  client_IP_1 (re,sync,no_subtree_check)

For multiple clients, specify each client on a separate file:

/mnt/nfs_share  client_IP_1 (re,sync,no_subtree_check)

/mnt/nfs_share  client_IP_2 (re,sync,no_subtree_check)

Step 4: Export the NFS Share Directory

After granting access to the preferred client systems, export the NFS share directory and restart the NFS kernel server for the changes to come into effect.

$ sudo exportfs -a

$ sudo systemctl restart nfs-kernel-server

Export NFS Share Directory

Step 5: Allow NFS Access through the Firewall

For the client to access the NFS share, you need to allow access through the firewall otherwise, accessing and mounting the shared directory will be impossible. To achieve this run the command:

$ sudo ufw allow from to any port nfs

Reload or enable the firewall (if it was turned off) and check the status of the firewall. Port 2049, which is the default file share, should be opened.

$ sudo ufw enable

$ sudo ufw status

Open NFS Port on Firewall

Install the NFS Client on the Client Systems

We’re done installing and configuring the NFS service on the Server, let’s now install NFS on the client system.

Step 1: Install the NFS-Common Package

As is the norm, begin by updating the system packages and repositories before anything else.

$ sudo apt update

Next, install nfs-common packages as shown.

$ sudo apt install nfs-common

Install NFS on Client System

Step 2: Create a NFS Mount Point on Client

Next,you need to create a mount point on which you will mount the nfs share from the NFS server. To do this, run the command:

$ sudo mkdir -p /mnt/nfs_clientshare

Step 3: Mount NFS Share on Client System

The last step remaining is mounting the NFS share that is shared by the NFS server. This will enable the client system to access the shared directory.

Let’s check the NFS Server’s IP address using the ifconfig command.

$ ifconfig

Check Ubuntu Server IP Address

To achieve this run the command:

$ sudo mount  /mnt/nfs_clientshare

Step 4: Testing the NFS Share on Client System

To verify that our NFS setup is working, we are going to create a few files in the NFS share directory located in the server.

$ cd /mnt/nfs_share/

$ touch file1.txt file2.txt file3.txt

Now head back to the NFS client system and check if the files exist.

$ ls -l /mnt/nfs_clientshare/
