Introduction​

This cheat sheet provides a quick reference for some common NFS (Network File System) commands and concepts. NFS is a distributed file system protocol that allows a user on a client computer to access files over a network as if they were on the local disk.

NFS Concepts​

Exporting Directories​

To share directories from the server to NFS clients, you need to export them.

  • Edit the NFS exports configuration file:

    sudo nano /etc/exports

  • Export a directory to a specific client:

    /path/to/shared/dir client_ip(options)

NFS Server Commands​

Managing the NFS server on the server-side involves starting, stopping, and checking its status.

  • Start the NFS server:

    sudo service nfs-kernel-server start

  • Stop the NFS server:

    sudo service nfs-kernel-server stop

  • Check the status of the NFS server:

    sudo service nfs-kernel-server status

NFS Client Commands​

On the client-side, you can mount and unmount NFS shares.

  • Mount an NFS share:

    sudo mount server_ip:/shared_dir /mnt/local_mount_point

  • Unmount an NFS share:

    sudo umount /mnt/local_mount_point

Viewing NFS Mounts​

You can view mounted NFS shares on a client.

  • List mounted NFS shares on the client:
    mount | grep nfs

NFS Security​

NFS allows you to control access to shared directories using export options.

  • Export a directory with read-only access:

    /path/to/shared/dir client_ip(ro)

  • Export a directory with read-write access:

    /path/to/shared/dir client_ip(rw)

NFS Command-Line​

  • Edit the NFS exports configuration file:

    sudo nano /etc/exports

  • Start the NFS server:

    sudo service nfs-kernel-server start

  • Stop the NFS server:

    sudo service nfs-kernel-server stop

  • Check the status of the NFS server:

    sudo service nfs-kernel-server status

  • Mount an NFS share:

    sudo mount server_ip:/shared_dir /mnt/local_mount_point

  • Unmount an NFS share:

    sudo umount /mnt/local_mount_point

  • List mounted NFS shares on the client:

    mount | grep nfs

Conclusion​

This cheat sheet covers some common NFS (Network File System) commands and concepts. NFS is a powerful protocol for sharing files and directories across a network, making it valuable for network file sharing and storage solutions; refer to the official NFS documentation for more in-depth information and advanced usage.
