Below steps should work for me;
hostnamectl set-hostname <server1.example.com>
vi /etc/hosts
10.1.1.1 server1.example.com server1
hostname -f
server1
In order to set your hostname, you will want to use the command
hostnamectl set-hostname yourhostnamehereAfter that, run
hostnamectlagain to confirm the change.
