However, NFS-mounted directories are not part of the system on which they are mounted, so by default, the NFS server refuses to perform operations that require superuser privileges. Superusers can do anything anywhere on their system. We’re going to share two separate directories, with different configuration settings, in order to illustrate two key ways that NFS mounts can be configured with respect to superuser access. Step 2 - Creating the Share Directories on the Host
Now that both servers have the necessary packages, we can start configuring them. Again, refresh the local package index prior to installation to ensure that you have up-to-date information:
Ubuntu setup nfs share install#
On the client server, we need to install a package called nfs-common, which provides NFS functionality without including any server components. Once these packages are installed, switch to the client server. Since this is the first operation that you’re performing with apt in this session, refresh your local package index before the installation: On the host server, install the nfs-kernel-server package, which will allow you to share your directories. We’ll begin by installing the necessary components on each server. Step 1 - Downloading and Installing the Components Throughout this tutorial we will refer to these IP addresses by the placeholders host_ip and client_ip.
Be sure to use the private network address, if available. You will need to know the IP address for both. Throughout this tutorial, we refer to the server that shares its directories as the host and the server that mounts these directories as the client.
Ubuntu setup nfs share how to#
If you’re using DigitalOcean Droplets for your server and client, you can read more about setting up a private network in our documentation on How to Create a VPC.For assistance setting up a non- root user with sudo privileges and a firewall, follow our Initial Server Setup with Ubuntu 20.04 guide.Each of these should have a non- root user with sudo privileges, a firewall set up with UFW, and private networking, if it’s available to you.
We will use two servers in this tutorial, with one sharing part of its filesystem with the other. In this guide, we’ll go over how to install the software needed for NFS functionality on Ubuntu 20.04, configure two NFS mounts on a server and client, and mount and unmount the remote shares. NFS provides a relatively standard and performant way to access remote systems over a network and works well in situations where the shared resources must be accessed regularly. This lets you manage storage space in a different location and write to that space from multiple clients. NFS, or Network File System, is a distributed file system protocol that allows you to mount remote directories on your server.
