Seems there’s no ntpd in centos7, how can I sync time in centos7?
I found out that
chrony should be used in centos7, what is manual way to update time using chrony?
I assume chronyd is something equivalent to ntpd? and what’s the command equivalent to
ntpdate -s time.nist.gov?
Unless you’ve changed chrony’s configuration, you don’t need to do anything but start the service.
systemctl enable --now chronyd.service
The default configuration automatically steps the clock at startup (using the
makestep directive) if it is more than one second different than the default NTP servers.
If you explicitly removed
makestep from the configuration, you can step the clock by using the command
You should NOT do this if you used the non-default
rtcfile option though, as it will cause the RTC drift to be recorded incorrectly.
For further details see the RHEL 7 chrony documentation.
