How To Change Hostname on Fedora 35

Change Hostname on Fedora 35

In this tutorial, we will show you how to Change the Hostname on Fedora 35. For those of you who didn’t know, A hostname is a human-readable string that helps people refer to a computer by a familiar name. As a system administrator, it is imperative to have a short but recognizable hostname to separate the server machines from each other. Often, a hostname is set during the installation process, but there are times when it needs to be changed.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step change your hostname on a Fedora 35.

Change Hostname on Fedora 35

Step 1. Before proceeding, update your Fedora operating system to make sure all existing packages are up to date. Use this command to update the server packages:

sudo dnf upgrade
sudo dnf update

Step 2. Displaying Your Current Hostname.

Let’s check the current hostname by using either the hostname or hostnamectl command:

hostnamectl

The example output below shows the static and transient hostnames:

Static hostname: localhost.localdomain
Transient hostname: fedora
         Icon name: computer-laptop
           Chassis: laptop
        Machine ID: 65fc9e69d00701bmwe46f31bc527888ed1
           Boot ID: 81ac938872bae0bmwe46cb288841ac93
  Operating System: Fedora 35 (Workstation Edition)
       CPE OS Name: cpe:/o:fedoraproject:fedora:35
            Kernel: Linux 5.15.10-200.fc33.x86_64
      Architecture: x86-64

To see the current static, transient, or pretty hostname, you can use the hostnamectl command with options, such as:

hostnamectl --static
hostnamectl --transient
hostnamectl --pretty

Step 3. Change Hostname on Fedora.

You can change the hostname of the Fedora system using the following command. For example, you need to set the computer hostname to fedora.idroot.us:

sudo hostnamectl set-hostname fedora.idroot.us

Step 4. Verify the Hostname.

Once changing the Hostname, verify it by typing the hostnamectl command. The result shows the system information along with a new static hostname:

hostnamectl

Output:

Static hostname: fedora.idroot.us
Transient hostname: fedora
         Icon name: computer-laptop
           Chassis: laptop
        Machine ID: 65fc9e69d00701bmwe46f31bc527888ed1
           Boot ID: 81ac938872bae0bmwe46cb288841ac93
  Operating System: Fedora 35 (Workstation Edition)
       CPE OS Name: cpe:/o:fedoraproject:fedora:35
            Kernel: Linux 5.15.10-200.fc33.x86_64
      Architecture: x86-64
