[CentOS] How to set hostname and domainnmae in CentOS 7?

[Gregory P. Ennis]

We can permanently set hostname using  hostnamectl set-hostname. How
can we
permanently set *domain name* in CentOS 7?
I found an article
<http://unix.stackexchange.com/questions/239920/how-to-set-the-fully-qu
alified-hostname-on-centos-7-0>
that recommended setting FQDN using hostnamectl. Is that the right way
to
set hostname and domainname at the same time using *hostnamectl
set-hostname* command?

 Running *hostnamectl set-hostname* will set the hostname in*
/etc/hostname*
but it doesn't change */etc/hosts*. What's the proper way of adding
hostname and FQDN to */etc/hosts *in CentOS 7?

Thanks,

Joe

Joe,

I used the following command in the /etc/rc.d/rc.local file which is
used at boot time.

/bin/domainname Domain.com

Make sure you also use :

chmod +x /etc/rc.d/rc.local

to make sure the file is executable.
