How to use ntp to update the centos system time from the time synchronization server

The newly installed CentOS system server may be set incorrectly. you need to adjust the time zone and adjust the time. The following is the process for CentOS to use NTP to synchronize time from a time server:

Perform the following steps to synchronize time in the CentOS system:

Copy codeThe code is as follows:
Cp/usr/share/zoneinfo/Asia/Shanghai/etc/localtime
Ntpdate us.pool.ntp.org

Easy!

The first sentence is to change the current time zone to Shanghai, that is, the + 8 zone. if you want to change the other time zones, you can go to 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:

Copy codeThe code is as follows:
Yum install-y ntpdate

Add scheduled tasks and synchronize the clock every 10 minutes

Copy codeThe code is as follows:
Crontab-e
0-59/10 ****/usr/sbin/ntpdate us.pool.ntp.org | logger-t NTP

In this way, we can solve the problem of inaccurate time in the CentOS system.
