I changed my hostname to /etc/host and /etc/hostname
I've rebooted the machine (vps) and checked in virtualmin=>networking=>Hostname and DNS Client and my new FQDN is already configured, I'm basing myself on a new domain that I bought for my new website to be the new FQDN name of my VPS : vps5.newdomain.com ... I have switched my PTR reverse with the new FQDN on my ISP (ovh and everything ok)
but every time I create a new virtual server, all settings in virtualmin=>server configuration=>DNS Records ( DNS Table )of this new domain added, comes with all the old settings! How do I update this within virtualmin and nginx and postfix(I have updated in /etc/postfix/main.cf)? virtualmin always did everything to me with the old domain vps5.olddomain.com, where I have to warn vitualmin that now my hostname is changed, is it a new hostname?
(I believe this is disrupting even in the generation of my dkim sign. because it is using as base a domain that no longer exists).
ubuntu 16.04/64bits /nginx /mysql /webmin 1.860(last) /postfix /Bind9.10
Thanks all/Regards.
Have you confirmed that you have also changed it here:
Webmin -> Networking -> Network Configuration -> Hostname and DNS Client, and you can change your hostname there.
Also Check
Virtualmin -> System Settings -> Server Templates -> Bind DNS Domain
