System Administration

7.8.1 Configure NTP

The file /etc/ntp.conf has many options. We want to define the time servers to use. You need the hostname (or IP address) of the time servers you wish to access. Using your editor, edit the file and add the line:

server <my time server name or IP address>

to the end of the file.

For example, let's use the name ts1.mydomain . Your entry is

server ts1.mydomain

You need the hostname (or IP address) of the time servers you wish to access. You should also add the server names to the file /etc/ntp/step-tickers.

This file just needs the name of the time servers (the word 'server' as used in the file /etc/ntp.conf is not needed)

7.8.2 Start the NTP Service

To start the NTP service manually:

service ntpd start

To cause NTP to start automatically on startup:

chkconfig ntpd on
