4.5. Updating the Host Name

If required, change the host name of the target system before you deploy.

Procedure 4.2. Updating the Host Name

  1. Update the host name in the /etc/sysconfig/network file: 
    NETWORKING=yes
HOSTNAME=New_Hostname
    Copy to Clipboard Toggle word wrap
  2. Also update the host name using the hostname command: 
    # hostname New_Hostnamehostname New_Hostname
    Copy to Clipboard Toggle word wrap
The above instructions set the host name locally, but not in DNS. For node hosts, this is used as the server identity. Generally it is best to use a name that matches how the host will resolve in DNS.
