Centos Time Synchronization

The newly installed server may be set incorrectly. You need to adjust the time zone and adjust the time as follows: Use NTP to synchronize data from a time server.

CP/usr/share/zoneinfo/Asia/Shanghai/etc/localtime

Ntpdate us.pool.ntp.org

The first sentence is to change the current time zone to Shanghai, which is + 8. If you want to change the other time zones, you can check the/usr/share/zoneinfo directory;

The second sentence is to use ntpdate to synchronize the standard time.

 

If ntpdate is not installed, you can run Yum:

Yum install-y ntpdate

Add scheduled tasks and synchronize the clock every 10 minutes

Crontab-e

0-59/10 ****/usr/sbin/ntpdate us.pool.ntp.org | logger-T NTP
