i've a problem with time syncronization of a CentOS 7 host with a Windows 2008 R2 Domain controller. If I use the command ntpdate -u host.domain the synchronization is ok. But using ntpd the time is always the same, here the result of the command ntpq -p:

 10.10.10.221    .LOCL.           1 u   65   64  377    1.740  965414.   4.054
 10.10.10.220    10.10.10.221     2 u   62   64  377    1.912  965408.  12.899

and the ntp.conf is the following:

driftfile /var/lib/ntp/drift
restrict default nomodify notrap nopeer noquery
restrict 127.0.0.1
restrict ::1
server 10.10.10.221 iburst prefer
server 10.10.10.220 iburst
includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
disable monitor
logfile /var/log/ntp.log

Centos 7 use systemd. I suggest you use it.

Use the command timedatectl

Enable network time synchronization:

timedatectl set-ntp True

Create a conf file:

vi /etc/systemd/timesyncd.conf

with content like this:

[Time] NTP= yourserver.org

Start systemd-timedated service:

systemctl start systemd-timedated
  • Umm, I don't believe centos chose to include systemd-timesyncd and so manufacturing a /etc/systemd/timesyncd.conf would have no effect. I'm willing to be corrected but systemd-timedated does not read this file. See unix.stackexchange.com/a/312716/80414 – shalomb Jul 9 '18 at 22:03
