设置开机自动同步Internet时间,并作定时同步任务
1、修改时区
rm -rf /etc/localtime ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime vim /etc/sysconfig/clock ZONE="Asia/Shanghai" UTC=false ARC=false
2、安装并设置开机自启
yum install -y ntp systemctl start ntpd systemctl enable ntpd
3、配置开机启动校验
vim /etc/rc.d/rc.local /usr/sbin/ntpdate ntp1.aliyun.com > /dev/null 2>&1; /sbin/hwclock -w
4、配置定时任务
crontab -e 0 */1 * * * ntpdate ntp1.aliyun.com > /dev/null 2>&1; /sbin/hwclock -w
