（2）編輯NTP服務(wù)器的主配置文件。

[root@block~]#vi/etc/ntp.conf編輯以下配置：restrict0 #放行NTP服務(wù)器來(lái)源#server0.iburst #去掉默認(rèn)的Internet上層NTP服務(wù)器#server1.iburst#server2.iburstserver0 #將上層NTP服務(wù)器配置為controller的IP地址14配置NTP服務(wù)（3）啟動(dòng)NTP服務(wù)器并將服務(wù)配置為開(kāi)機(jī)自動(dòng)啟動(dòng)。[root@block~]#servicentpdstartStartingntpd:[OK][root@block~]#chkconfig

ntpdon

（4）檢查NTP服務(wù)的配置結(jié)果。等待5-15分鐘，檢查block是否已經(jīng)與controller的NTP服務(wù)器同步。
