Centos system time synchronization (NTP)

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

The newly installed centos system server may be set incorrectly. You need to adjust the time zone and time.

The following is how the centos system uses NTP to synchronize data from a time server:
To change the current time zone to Shanghai, you can go to the/usr/share/zoneinfo directory if you want to change it to another time zone:

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

Use ntpdate to synchronize the Standard Time:

Ntpdate us.pool.ntp.org

Note:

If ntpdate is not installed, you can run Yum:

YumInstall-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

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