I installed ntp on a centos server.
I modified /etc/ntp.conf
replacing the default server entries with one entry to my internal NTP server's IP (1.2.3.4 is the IP of the NTP server):
server 1.2.3.4 iburst
When I reboot the server and run ntpstat I see this:
unsynchronised
polling server every 64 s
Then I run sudo ntpdate 1.2.3.4
and see this message:
1 Dec 19:22:35 ntpdate[2339]: the NTP socket is in use, exiting
Then I stop the service (systemctl stop ntpd
) and run sudo ntpdate 1.2.3.4
again to see it sync successfully:
1 Dec 19:25:11 ntpdate[2351]: adjust time server 1.2.3.4 offset 0.005316 sec
Now when I start the service back up and run ntpstat I see this message:
synchronised to NTP server (1.2.3.4) at stratum 4
time correct to within 8065 ms
polling server every 64 s
If I reboot now and run ntpstat it will say unsynchronized. What am I doing wrong? It should be automatically syncing to the IP of the NTP server I put in the config file right?
