How to Set Up the NTP Server

The NTP server is on a separate system from OpenStack nodes.

1. Install the NTP package.

   ntp-server# pkg install ntp

2. Install the configuration file.

   ntp-server# cp /etc/inet/ntp.server /etc/inet/ntp.conf

3. Edit the /etc/inet/ntp.conf file by configuring the server and driftfile keywords.

   For example:

   server 127.127.1.0 prefer
   ...
   driftfile /var/ntp/ntp.drift

   ---

   Note -  127.127.1.0 is not an IP address. It is a format used to refer to a clock that provides accurate time to the server. Make sure to read the comments in the ntp.conf file that explains the server keyword.

   ---

4. Create the /var/ntp/ntp.drift file as you have defined in the previous step.

   ntp-server# touch /var/ntp/ntp.drift

5. Start the ntp service.

   ntp-server# svcadm enable ntp
