Why isn’t the hostname command getting the FQDN from /etc/hostname?

Question

I set the hostname.

# more /etc/hostname
kafka01.ocff4.com

The hostname is still as follows.

hostname
kafka01

I restart using the following command.

 systemctl restart systemd-hostnamed

But still, hostname does not show the FQDN.

hostname
kafka01

Why did systemctl restart systemd-hostnamed not take affect? Is it a bug?

Take a look at your /etc/sysconfig/network file. If your hostname isn't present in the file, place the following line in it: hostname kafka01.ocff4.com

You'll also have to "sudo hostname kafka01.ocff4.com" at the command line to make the change take affect immediatly, or restart to make the change take affect.

With systemd you should be using hostnamectl – Raman Sailopal Oct 23 '17 at 13:36
