Controller node

Controller node

Perform these steps on the controller node.

Install and configure components

  1. Install the packages:

    # apt-get install chrony
  1. Edit the /etc/chrony/chrony.conf file and add, change, or remove the following keys as necessary for your environment:

    server NTP_SERVER iburst

    Replace NTP_SERVER with the hostname or IP address of a suitable more accurate (lower stratum) NTP server. The configuration supports multiple server keys.


    By default, the controller node synchronizes the time via a pool of public servers. However, you can optionally configure alternative servers such as those provided by your organization.

  2. Restart the NTP service:

    # service chrony restart
