Synchronize time on linux

I am using the NTP service to synchronize the time.

1. Install NTP

yum install ntp

2. Execute the command line

ntpdate -u ntp.api.bz

This command statement means: synchronize the time of the local server with the time on ntp.api.bz; where ntp.api.bz is the NTP server in Shanghai.

It can also be synchronized to other servers, http://www.ntp.org.cn/

The following errors may be reported during the synchronization process:

no server suitable for synchronization found

The reason for this error may be: the synchronization server you selected is incorrect, try to change the synchronization server.
