If you want to sync your Linux server time with specific network time servers? Okay, quick steps for you!
* Ensure you have NTP installed. If not use the command below.
For installation on Debian or Ubuntu.
sudo apt-get install ntp
For Redhat or CentOS.
yum install ntp
* Locate the /etc/ntp.conf file. There you can find the server lines. Add your preferred server to the file.
* Now restart or start the NTPD service:
/etc/init.d/ntpd restart
* To update the time, stop the NTP service and run the command below, swapping out your preferred server for pool.ntp.org.
/usr/sbin/ntpdate pool.ntp.org
That’s it!
