Host name is not persistent in CentOS 7

[realjumy]

Hi guys.

I tried everything to sort this. I have chosen a proper host name during the installation, I have tried changing the hosts file, using VestaCP panel... But the host name for my installation continues changing to that one defined by my VPS providers (OVH). Is any of you having the same issue or knows how to change it and make it persistent?

Thanks!

Edit:

After communicating with OVH, the answered me the following:

1. Edit /etc/sysconfig/network:

Code: Select all

HOSTNAME=hostname.domain.com

2. Update /etc/hosts:

Code: Select all

149.202.50.229 hostname.domain.com hostname

3. Run the hostname command to get OS to remember:

Code: Select all

hostnamectl set-hostname hostname.domain.com

4. Check if it knows the hostname:

Code: Select all

[root@vps ~]# hostname

hostname.domain.com

5. Restart the interface:

Code: Select all

/etc/init.d/network restart

If you reboot the OS it should stick with the set hostname.

I can confirm that it works.

Code: Select all

/etc/sysconfig/network

contained a message asking not to modify its content, and until now, I was respecting it (and maybe that's the reason why it was not working).
