Please use the Web User Interface (WUI), not the Phone User Interface (PUI). But plenty of times, like with a production server, one would like to execute that rename, but not reboot one's host.

What I am familiar with is executing the above two steps and then rebooting your host. Prior to changing the hostname, your-hostname is the current (soon to be former hostname) and as a part of changing your host's hostname, one replaces that name with the new name. It acts as bootstrapping while your host is booting up and establishing itself within your network.
Ubuntu in the /etc/hosts file has the line: 127.0.1.1 your-hostname your-hostname In the /etc/hostname one just replaces the current hostname (soon to be former hostname) with the new hostname. In the web console, click the System tab in the left column. First, install and enable Cockpit: sudo dnf install cockpit. I know that to rename the host, I edit the files: Using Cockpit, you can change the static hostname for your own machine, or any machine you administer (as long as it has Cockpit enabled). However, we are running Ubuntu in our production environment so we chose not to use the graphical desktop or utilities in order not to have those features consume resources we need in our production environment. How do I change a Linux host's hostname and get that change to take effect without a reboot?Ī big feature of Ubuntu is the graphical desktop and graphical system utilities.

I know it is possible, but I can't remember how to do it.
I searched for an answer to this question on serverfault and could not find it.
