To configure an NTP server on a vCloud Availability appliance post-deployment, update the settings via command line operations on each appliance:
- SSH to the appliance whose NTP settings you need to update and login as the root user.
- Edit the timesyncd.conf file with a text editor such as vi:
vi /etc/systemd/timesyncd.conf
- In the [Time] section edit the NTP entry with the correct NTP server address:
[Time]
#FallbackNTP=time1.google.com time2.google.com time3.google.com time4.google.com
NTP=ntpAddress
- Restart the network service:
systemctl restart systemd-networkd
- Restart the timesync service:
systemctl restart systemd-timesyncd
- Verify that the time on the appliance is now synchronizing with the NTP server.
