I installed Hestia a couple of months ago and want to change the domain name that I originally used in the install. What command is done to change the domain name? Furthermore, I already have the domain that I want to use as an additional web domain added into the Hestia Control Panel. How is this best done? And will I have to reassign SSL certificates in the process? Lastly, what is the best way to manage backup and recovery if the process doesn’t go well?
You won’t need a backup but:
To make sure you have your backup in the /backup directory you can do it with this command: ls -l /backup
The list will show the creation date and time for the backup. In case it is not working, then look in the docs or try to set your backup via UI.
Create the DNS entry
Go to your DNS server (that can be your hestiacp server or not) and configure the new hostname DNS entry: new.mydomain.com A 123.123.123.123
Run the command $HESTIA/bin/v-change-sys-hostname new.mydomain.com
Enable letsencrypt $HESTIA/bin/v-add-letsencrypt-host
If it shows an error code 400. It is maybe because the new DNS has not been yet propagated or it is not correctly configured.
Bear in mind that if the commands dont show any output, they have been successfully executed.
