Question full hostname in plesk

[yiannis yiannis]

Hello plesk forum!

Trying to read on the forum and understand what I should do with the full hostname in plesk, makes me even more confused.
We recently rent a dedicated server and successfully complete the subscription migration from our old sharing hosting. Now I see that the full hostname in server settings, is set to localhost.localdomain.

I carefully read the below post but I'm bit afraid of messing things up.
https://talk.plesk.com/threads/full-hostname-under-server-system-settings.302662/

Could you please let me know what's the right process for getting a proper hostname both for plesk and server itself? Additional info on the screenshots.

The Hostname of the server and the host name of the plesk are same. The host name that you set to the server will be picked up by Plesk or you can use it for Plesk.
The hostname should be a fully qualified domain name (( FQDN ) . So if you have a domain registered as abc.com you can assign the hostname to the server as server.abc.com or box.abc.com

Thanks for you reply!

So, I should first change my server's hostname e.g. server.abc.com following this process - https://support.rackspace.com/how-to/centos-hostname-change/
And then I should just apply the same hostname on plesk server settings, is that right?
Anything to do on the DNS server records?

It's just the name of your server. You only have to set it in Plesk.

For example:

server1.mydomain.com

So 'server1' is the specific name of your server. If one day you'll have a second server, you can call it server2.mydomain.com

You think that I don't have to worry about this one?

Be carefull because this update can block some services, if you provides zero-stop-services, before you change the hostname, make a full backup or snapshot.

I have no idea what that means. If you have a fresh Plesk install I wouldn't worry about it.

Thanks for your replies.

By assigning the server hostname on plesk, it changed automatically the /etc/hostname and /etc/hosts files.

I had to do it manually on /etc/sysconfig/network by adding HOSTNAME=myserver.domain.com, restarting also the network.

I had to add it also manually on /etc/postfix/main.cf by changing myhostname=myserver.domain.com. This might be necessary since some mail servers may reject emails if they sent using initial localhost.localdomain.
