• 本地时间服务器(主)配置文件如下

    driftfile /var/lib/ntp/drift
    restrict 192.168.0.0 mask 255.255.0.0 nomodify notrap
    server 127.127.1.0
    fudge 127.127.1.0 stradum 4
    includefile /etc/ntp/crypto/pw
    keys /etc/ntp/keys
  

• 本地时间服务器(从)配置文件如下

    driftfile /var/lib/ntp/drift
    restrict 192.168.0.0 mask 255.255.0.0 nomodify notrap
    server center
    fudge 127.127.1.0 stradum 5
    includefile /etc/ntp/crypto/pw
    keys /etc/ntp/keys
  

• 需要同步的服务器配置如下

    driftfile /var/lib/ntp/drift
    server master01 prefer
    server master02
    includefile /etc/ntp/crypto/pw
    keys /etc/ntp/keys
