NTP server centos 7 fresh installation and configuration
I am gonna show you how to configure NTP Server for time sync.
First of all, we need to install the ntpd and ntpdate clients on our Linux host. I’m using CentOS linux .
yum install ntp ntpdate
systemctl start ntpd
systemctl enable ntpd
systemctl status ntpd
Now that that’s out of the way let’s 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
What we’re doing is telling 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 let’s restart the ntpd daemon.
systemctl restart ntpd
Now let’s check if NTP synchronization is enabled and running.
timedatectl
And for the last hurrah, we will set the hardware clock to the current system time using the -w switch.
hwclock -w
Congratulations! You’ve now successfully set your NTP client on CentOS.
