How to change the hostname on CentOS 8?

You can change the hostname using the hostnamectl command by running the following commands:

sudo hostnamectl set-hostname host.example.com

sudo hostnamectl set-hostname "Your Pretty HostName" --pretty

sudo hostnamectl set-hostname host.example.com --static

sudo hostnamectl set-hostname host.example.com --transient

For example, to change the system static hostname to host.eldernode.com, you would use the following command:

sudo hostnamectl set-hostname host.eldernode.com
