Change a server's hostname in NTC Virtual Appliance
By default, NTC server is started with the server’s given name as the
hostname. However, certificates requires a valid fully
qualified domain name (FQDN) for the hostname for proper verification.
This article describes how to change a
server hostname in NTC Virtual Appliance.
Change a server’s hostname
Login to NTC VA in the console or using SSH.
Using a text editor, open the server’s /etc/sysconfig/network file.
The following example shows how to open this file in the GNU nano text
# sudo nano /etc/sysconfig/network
HOSTNAME= value to match your FQDN hostname,
as shown in the following example:
Open the file at /etc/hosts. To update the information for internal
networking, change the host that is associated with the main IP address
for your server, as shown in the following example:
127.0.0.1 localhost localhost.localdomain
18.104.22.168 hostname.domain.com hostname
-- INSERT -- 2,43-57 ALL
hostname command. This command enables you to change the
hostname on the server that the command line remembers, but it does
not actively update all of the programs that are running under the
old hostname. The following code provides an example:
[root@defiant ~]# hostnamectl set-hostname hostname.domain.com
[root@defiant ~]# hostname
Use the following command to restart networking on your server to ensure that changes persist on restart:
# /etc/init.d/network restart
