--------------------------------
|
|
|
|
1. Install the packages:
|
|
|
|
.. only:: ubuntu or debian
|
|
|
|
.. code-block:: console
|
|
|
|
# apt-get install chrony
|
|
|
|
.. only:: rdo
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install chrony
|
|
|
|
.. only:: obs
|
|
|
|
On openSUSE:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper addrepo -f obs://network:time/openSUSE_Leap_42.1 network_time
|
|
# zypper refresh
|
|
# zypper install chrony
|
|
|
|
On SLES:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper addrepo -f obs://network:time/SLE_12_SP1 network_time

|
|
verify the fingerprint of the imported GPG key before using it.
|

2. Edit the ``/etc/chrony/chrony.conf`` file and comment out or remove all
|
|
but one ``server`` key. Change it to reference the controller node:
|
|
|
|
.. code-block:: ini
|
|
|
|
server controller iburst
|
|
|
|
3. Restart the NTP service:
|
|
|
|
.. code-block:: console
|
|
|
|
# service chrony restart
|
|
|
|
.. only:: rdo or obs
|
|
|
|
2. Edit the ``/etc/chrony.conf`` file and comment out or remove all but one
|
|
``server`` key. Change it to reference the controller node:
|
|
|
|
.. code-block:: ini
|
|
|
|
server controller iburst
|
|
|
|
3. Start the NTP service and configure it to start when the system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable chronyd.service
|
|
# systemctl start chronyd.service
