To make changes to the hostname take effect immediately, follow these steps:

  1. Open the terminal and log in as the root user.
  2. Set the hostname to the new hostname.
  3. Set the hostname to “myhostname” using the hostnamectl command.
  4. Restart the systemd-hostnamed service using systemctl.

Please note that the above steps apply to Linux distributions using systemd, such as Red Hat Enterprise Linux (RHEL), CentOS, Ubuntu, etc. For other distributions, there may be slightly different commands or steps.
