Steps to set a server's time source to the NTP server:
timedatectl set-timezone UTC
In
chronyd.conf
, add or modify the following IP address setting.When using SCS, use the Swarm-internal IP address.
server {SCS Swarm-internal IP address} iburst
To use a different NTP server:
server {NTP server IP} iburst
NOTE:
This must not be a Windows Directory SNTP server.
Restart chrony:
> systemctl enable chronyd > systemctl restart chronyd
Verify that time sources are correct.
chronyc sources
Verify there is an asterisk (*) next to one of the lines, indicating the time has been synchronized. Example:210 Number of sources = 1 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^* telamon.tx.caringo.com 3 8 377 152 +5225ns[+7036ns] +/- 98ms
Once the time is synchronized, sync the BIOS clock.
hwclock --systohc
