ubuntu在命令行下同步时间

1. 修改 /etc/timezone的时钟为UTC时钟.

echo "Asia/Shanghai" > /etc/timezone

 

2.修改时区 

$sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

 

3.同步时钟服务器 

$sudo ntpdate cn.pool.ntp.org

　　报错 21 Feb 03:04:30 ntpdate[19759]: the NTP socket is in use, exiting 解决方法，停止npdd服务

/etc/init.d/ntpd stop

4.写入BIOS 

$sudo hwclock --systohc
