Configure NTP Server CentOS/Redhat/Oracle Linux

This process goes over configuring a NTP server, so that the server is dishing out time to clients. Let’s get started

from here we need to install the ntp server

configure NTP to start after a reboot, and now as well

from here we need to edit the config file

add the following lines to the config:

we need to add our local networks (and remote if you have any) that are allowed to sync with the time server

you want to add a few extra other than the default to synchronize with, usually something local

un-comment the following line, this allows the server to check against itself if it cannot reach all of the internet time servers

like so:

at this point we need to sync our time server with an accurate time source

at this point there is one final step….

WAIT 5 MINUTES FOR THE SERVER TO SYNC UP WITH INTERNET NTP SERVERS

IF YOU DO NOT WAIT, YOUR NTP SERVER WILL NOT APPEAR TO WORK…….

That’s it!
