Set the same time for all cluster nodes

配置服务器
修改 /etc/ntp.conf
加上需要同步得网段
restrict 10.64.3.0 mask 255.255.255.0
启动ntp
chkconfig ntpd on
/etc/init.d/ntpd start
# vi /etc/ntp/step-tickers
加入一行
pool.ntp.org
这样每次ntpd启动时，会自动连接该国际标准时间服务器；

配置客户端
ntpdate ip_of server

0 3 * * * /usr/sbin/ntpdate 192.168.0.179
