How to Configure NFS: A Step-by-Step Guide

Network File System (NFS) is a popular distributed file system protocol that allows you to share files and directories between multiple Linux servers. Setting up NFS can greatly simplify file sharing and improve collaboration across your network. In this guide, we will walk you through the process of configuring NFS on your Linux system.

Step 1: Install NFS Server

The first step in configuring NFS is to install the NFS server on your system. Depending on your Linux distribution, you can install the NFS server using the following commands:

  • sudo apt-get install nfs-kernel-server (for Debian/Ubuntu)
  • sudo yum install nfs-utils (for CentOS/RHEL)

Step 2: Create NFS Shared Directory

Next, you need to create a directory on your server that you want to share via NFS. You can create a new directory using the following command:

sudo mkdir /nfs_share

Step 3: Configure NFS Exports

After creating the shared directory, you need to configure NFS exports to define which directories are shared and the access permissions for those directories. You can edit the /etc/exports file using a text editor such as nano or vim:

sudo nano /etc/exports

In the /etc/exports file, add the following line to export the directory you created:

/nfs_share *(rw,sync,no_subtree_check)

Step 4: Export the NFS Share

After saving the /etc/exports file, you need to export the NFS share and reload the NFS server configuration. You can export the NFS share and reload the configuration using the following commands:

sudo exportfs -a

sudo systemctl restart nfs-server

Step 5: Configure NFS Clients

Finally, you need to configure NFS clients to mount the NFS share on their systems. On the client system, you can mount the NFS share using the following command:

sudo mount :/nfs_share /mnt

Replace with the IP address of the NFS server. Once the NFS share is mounted, you can access the shared directory on the client system.

Conclusion

Configuring NFS can greatly simplify file sharing and collaboration across your network. By following the steps outlined in this guide, you can set up NFS on your Linux system and start sharing files and directories with ease. Remember to secure your NFS configuration by restricting access to authorized users only.

Happy file sharing!
