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

  1. Login to NTC VA in the console or using SSH.

  2. 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 editor:

     # sudo nano /etc/sysconfig/network
  3. Modify the HOSTNAME= value to match your FQDN hostname, as shown in the following example:

     HOSTNAME=myserver.domain.com
  4. 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
     123.45.67.89   hostname.domain.com   hostname
     ~
     ~
     ~
     ~
     -- INSERT --                         2,43-57    ALL
  5. Run the 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
     hostname.domain.com
  6. Use the following command to restart networking on your server to ensure that changes persist on restart:
      # /etc/init.d/network restart
