Hostname is not properly set!

[jclins]

I'm trying to install CWP 7 on Centos CentOS 7 64bit. I have already installed other times but was having error in outlook and I am trying to sort out and understand where the error is.

In this latest release of CWP 7, an error is occurring and the installation is halting with this message:

Hostname is not properly set!

My footerprints:
0-Change MYDOMAIN.COM NAMESERVERS to NS1.CENTOS-WEBPANEL.COM and NS2.CENTOS-WEBPANEL.COM
1-change hostname for SRV1.MYDOMAIN.COM
2-update CENTOS (yum -y update && reboot)
3-install cwp-el7-latest

at this moment I get the error message.

Could someone tell you where the error is?  In advance, thank you

My Mistake

I was changing the hostname with the hostname srv.dominio.com command
But when the server restarted this name was not recorded

The correct command:
hostnamectl set-hostname srv.DOMINIO

And for check:
hostname status

[ring_c]

And for check:
hostname status

Be careful!!! This "hostname status" command will change your hostname to "status"!
Do not run this command unless that's what you want your hostname to be!
