NFS Mounting in Linux: Syntax and Steps for Mounting NFS Shares
In this article, we will explore the syntax and steps for mounting NFS shares in Linux. NFS (Network File System) is a distributed file system protocol that allows a client to access files over a network as if they were on the local machine. Mounting NFS shares in Linux enables users to access remote files and directories seamlessly.
Introduction
Mounting NFS shares in Linux is a crucial skill for system administrators and users who need to access files and directories located on remote servers. By mounting NFS shares, Linux users can treat remote files as if they were local, enabling them to read, write, and execute files on the NFS server.
What is NFS?
NFS, or Network File System, is a distributed file system protocol that allows a client to access files over a network. It was developed by Sun Microsystems and has become a standard protocol for sharing files between Unix-like systems.
NFS operates on the client-server model, where the NFS server exports directories that can be mounted by NFS clients. The clients can then access the files and directories on the server as if they were on their local machine.
Why Mount NFS in Linux?
Mounting NFS shares in Linux offers several advantages:
- Centralized Storage: By mounting NFS shares, users can access files and directories stored on a central server, allowing for easy collaboration and file sharing.
- Seamless Integration: Mounting NFS shares makes remote files and directories appear as if they were on the local machine, enabling users to interact with them using familiar commands and tools.
- Efficient Resource Utilization: NFS allows multiple clients to access the same files simultaneously, reducing the need for duplicate copies and optimizing storage utilization.
- Improved Performance: NFS utilizes caching mechanisms to improve performance, reducing the need for frequent network transfers.

Mounting NFS with read-only access
To mount an NFS share with read-only access, use the following syntax:
mount -t nfs -o ro <NFS server IP or hostname>:<remote directory> <local directory>
Replace <NFS server IP or hostname>
with the IP address or hostname of the NFS server, <remote directory>
with the directory on the NFS server you want to mount, and <local directory>
with the directory on your local machine where you want to mount the NFS share.
Mounting NFS with read-write access
To mount an NFS share with read-write access, use the following syntax:
mount -t nfs -o rw <NFS server IP or hostname>:<remote directory> <local directory>
Replace <NFS server IP or hostname>
with the IP address or hostname of the NFS server, <remote directory>
with the directory on the NFS server you want to mount, and <local directory>
with the directory on your local machine where you want to mount the NFS share.
Mounting NFS with specific NFS version
To mount an NFS share with a specific NFS version, use the following syntax:
mount -t nfs -o vers=<NFS version> <NFS server IP or hostname>:<remote directory> <local directory>
Replace <NFS version>
with the specific NFS version you want to use, <NFS server IP or hostname>
with the IP address or hostname of the NFS server, <remote directory>
with the directory on the NFS server you want to mount, and <local directory>
with the directory on your local machine where you want to mount the NFS share.
Mounting NFS with specific mount options
To mount an NFS share with specific mount options, use the following syntax:
mount -t nfs -o <mount options> <NFS server IP or hostname>:<remote directory> <local directory>
Replace <mount options>
with the specific mount options you want to use, <NFS server IP or hostname>
with the IP address or hostname of the NFS server, <remote directory>
with the directory on the NFS server you want to mount, and <local directory>
with the directory on your local machine where you want to mount the NFS share.
Mounting NFS with specific authentication options
To mount an NFS share with specific authentication options, use the following syntax:
mount -t nfs -o <authentication options> <NFS server IP or hostname>:<remote directory> <local directory>
Replace <authentication options>
with the specific authentication options you want to use, <NFS server IP or hostname>
with the IP address or hostname of the NFS server, <remote directory>
with the directory on the NFS server you want to mount, and <local directory>
with the directory on your local machine where you want to mount the NFS share.
Mounting NFS with specific timeout options
To mount an NFS share with specific timeout options, use the following syntax:
mount -t nfs -o <timeout options> <NFS server IP or hostname>:<remote directory> <local directory>
Replace <timeout options>
with the specific timeout options you want to use, <NFS server IP or hostname>
with the IP address or hostname of the NFS server, <remote directory>
with the directory on the NFS server you want to mount, and <local directory>
with the directory on your local machine where you want to mount the NFS share.
Mounting NFS with specific file locking options
To mount an NFS share with specific file locking options, use the following syntax:
mount -t nfs -o <file locking options> <NFS server IP or hostname>:<remote directory> <local directory>
Replace <file locking options>
with the specific file locking options you want to use, <NFS server IP or hostname>

with the directory on your local machine where you want to mount the NFS share.
Steps for Mounting NFS Shares in Linux
Step 1: Install NFS client
Before mounting NFS shares, ensure that the NFS client package is installed on your Linux system. You can install it using the package manager specific to your distribution. For example, on Ubuntu, you can use the following command:
sudo apt-get install nfs-common
Step 2: Create a local directory for mounting
Create a directory on your local machine where you want to mount the NFS share. This directory will serve as the mount point. You can choose any name for the directory. For example, to create a directory named “nfs-mount” in the root directory, use the following command:
sudo mkdir /nfs-mount
Step 3: Mount the NFS share
Once the NFS client is installed and the mount point is created, you can proceed to mount the NFS share. Use the appropriate mount command based on the NFS version and options you want to use. For example, to mount an NFS share using version 3, use the following command:
sudo mount -t nfs <NFS server IP or hostname>:<remote directory> <local directory>
Step 4: Verify the mount
After mounting the NFS share, you can verify the mount by listing the contents of the mount point directory. If the mount was successful, you should see the files and directories from the NFS server listed. For example, to list the contents of the “nfs-mount” directory, use the following command:
ls /nfs-mount
Conclusion
Mounting NFS shares in Linux provides a convenient way to access remote files and directories as if they were on the local machine. By understanding the syntax and following the steps outlined in this article, you can easily mount NFS shares in Linux and take advantage of centralized storage and seamless integration.
