Configure NTP

To use NTP:

Install NTP on the machines that will host Eucalyptus components.

yum install ntp

Open the /etc/ntp.conf file and add NTP servers, if necessary, as in the following example.


Save and close the file. Synchronize your server.

ntpdate -u YOUR_NTP_SERVER

Configure NTP to run at reboot.

systemctl enable ntpd.service

Start NTP.

systemctl start ntpd.service

Synchronize your system clock, so that when your system is rebooted, it does not get out of sync.

hwclock --systohc

Repeat on each host machine that will run a Eucalyptus service.
