NTP

Question 1

Synchronize time using other NTP peers

Answer 1

Synchronize time using other NTP peers.

If you didn’t already set up a time server, learn how to configure a NTP server.

1. Install the NTP package:
# yum install -y ntpd

2. Edit the /etc/ntp.conf file and comment the following lines if you don’t want to use the default timeservers:
#server 0.centos.pool.ntp.org
#server 1.centos.pool.ntp.org
#server 2.centos.pool.ntp.org

3. In the same file, add the name (or IP address) of your time server:
   server timeserver

4. Check the system date:
# date

5. If the system date is more than 15 minutes away from real time, set up the date from your time server:
# ntpdate timeserver

6. Activate the NTP service:
# chkconfig ntpd on

7. Start the NTP service:
# service ntpd start

8. Check that the service is working properly:
# ntpq -p
