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.

# timedatectl

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.
