This article is to help you to configure the NTP Client to synchronize with NTP Servers.
First, You need to install the ntpd and ntpdate clients on Linux host.
# yum install ntp ntpdate
If yum is not installed, then just run the following command: sudo apt install yum. Once that’s installed you need to start and enable the ntpd service.
# systemctl start ntpd
# systemctl enable ntpd
# systemctl status ntpd
Now run the following command to configure the NTP Servers.
# ntpdate -u -s 0.centos.pool.ntp.org 1.centos.pool.ntp.org 2.centos.pool.ntp.org
Command tells the ntpdate to use an unprivileged port for outgoing packets with the -u switch and to write logging output to the system syslog facility using the -s switch
Next restart the ntpd daemon.
# systemctl restart ntpd
Now check if NTP synchronization is enabled and running.
And for the last, you need to set the hardware clock to the current system time using the -w switch.
# hwclock -w
You’ve now successfully set your NTP client on CentOS. Hope this article has helped you to Sync your server with NTP Time Servers.
