Setup NTP on CentOS 5.2

I am working on building a DRBD cluster and as with all cluster tools , you must have a synced time between nodes.

1. install ntp

yum -y install ntp

2. enable ntp on boot

chkconfig ntpd on

3.run a manual time sync before starting the service

ntpdate 0.pool.ntp.org

4. start the service

service ntpd start
