How to Configure a Static and Persistent Hostname on Linux

August 14, 2023 / Servers, Hosting & Email

This guide helps in understanding how to configure a static and persistent hostname on Linux. Static Hostname on Linux is a fixed name for your computer used for identification within a network, whereas a persistent hostname ensures the static hostname remains the same even after the computer restarts.

Let us find out how to configure a static and persistent hostname-

  1. First, let us configure a Static hostname-
    1. Execute the following command to display the system’s hostname-
      $ hostname
    2. You can also temporarily use the hostname command to modify the system’s name. Here is an example:
      $ hostname
    3. The change is temporary. Once you reboot, the changes will revert.
  2. Now, let us configure a persistent hostname-
    1. To make a lasting change to the hostname, you can either use the “hostnamectl” command or directly edit the configuration file located at “/etc/hostname”.
    2. Let us take an example of changing the hostname permanently using the hostnamectl command. This shows the change:
      $ hostnamectl set-hostname
    3. Do not miss out to verify the change using the hostname command after executing the command.
    4. By presenting the /etc/hostname file contents, you can check the entry.
