Other nodes

Other nodes reference the controller node for clock synchronization. Perform these steps on all other nodes.

Install and configure components

  1. Install the packages.

    For Ubuntu:

    # apt install chrony

    For RHEL or CentOS:

    # yum install chrony

    For SUSE:

    # zypper install chrony

  2. Configure the chrony.conf file and comment out or remove all but one server key. Change it to reference the controller node:

    For RHEL, CentOS, or SUSE, edit the /etc/chrony.conf file:

    server controller iburst

    For Ubuntu, edit the /etc/chrony/chrony.conf file:

    server controller iburst

  3. Comment out the pool 2.debian.pool.ntp.org offline iburst line.

  4. Restart the NTP service.

    For Ubuntu:

    # service chrony restart

    For RHEL, CentOS, or SUSE:

    # systemctl enable chronyd.service
# systemctl start chronyd.service
