How to change or get a server hostname on the Plesk server?
Note: A server hostname must be a fully qualified domain name (FQDN). The changes are not instant. It requires 24-48 hours to get a new hostname propagated through all the DNS servers.
Warning: Server providers might deny hostname change, in such cases contact the server provider.
In Plesk interface
Go to Tools & Settings > Server Settings > Full hostname:
Note: You must be Plesk Administrator to be able to see or change the hostname.
Via CLI (Linux only)
Connect to the server using SSH as root
To view hostname execute the command:
To change server hostname execute the following command with preferred hostname value instead of host.example.com:
# plesk bin server_pref –update -hostname host.example.com
Restart sw-cp-server and sw-engine services:
# service sw-cp-server restart
# service sw-engine restart
If the hostname was not changed, use the native SystemD utility(CentOS7/Debian8+/Ubuntu16):
# hostnamectl set-hostname host.example.com
Note: In some cases, server restart is required.
For Google Cloud instance the changes will not be saved after server restart. Use the following workaround: https://cloud.google.com/compute/docs/instances/custom-hostname-vm
