Install and Configure NTP on CentOS

This is a simple tutorial on how to install and configure the NTP service to make sure your clock is accurate and synched on your system.

Install NTP

$ yum install ntp

Once that's done turn on the NTP service so that it automatically starts on boot.

$ chkconfig --level 2345 ntpd on

Synchronize Clock

Here we are just setting the service the NTP server will use to synchronize the clock with, in this case we are using the 0.pool.ntp.org server

$ ntpdate pool.ntp.org

Start NTP Service

$ /etc/init.d/ntpd start
