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.
