Safely change hostname

[danderzei]

Hi I like to retire the domain use for the hostname in my hestia setup. This hostname domain is not used for anything else and I like to stop paying for it.

How can I safely change the hostname? ChatGPT suggests:

hostnamectl set-hostname new.hostname.com

Update the /etc/hosts file.

v-change-sys-hostname new.hostname.com

systemctl restart hestia

rm -rf /usr/local/hestia/ssl/*

v-add-letsencrypt-host

Lastly, update PTR record (reverse DNS) to match the new hostname for email deliverability.

Are these the correct steps to take?

Hi @danderzei

You only need to do these steps:

v-change-sys-hostname new.hostname.com
v-add-letsencrypt-host
Lastly, update PTR record (reverse DNS) to match the new hostname for email deliverability.

hostnamectl and editing the hosts file are already handled by v-change-sys-hostname. Additionally, there is no need to remove SSL files, as doing so could cause hestia-nginx to fail to start.

Great, that is much more straightforward.

Just used these steps. In the letsencrypt bit, I get an error:

Error: Unable to add hestia.prevos.net. prevos.net belongs to a different user
Error: web domain hestia.prevos.net doesn't exist

I indeed use prevos.net as a web service. hestia.prevos.net exists but is not registered. Should I register it as admin?

Two options:

Option 1
Remove web domain hestia.prevos.net from the current admin user and add it to the user that has main domain prevos.net

Option 2
Remove the policy that enforces subdomain ownership.

v-change-sys-config-value ENFORCE_SUBDOMAIN_OWNERSHIP no

v-change-sys-config-value ENFORCE_SUBDOMAIN_OWNERSHIP no

Great that worked.
