Configure CentOS with NTP Time Servers

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.
