The ntp software package is no longer supported by default in CentOS8.0, and time synchronization is implemented by chrony. But I have become accustomed to using ntpdate to synchronize the system time, including CentOS7 and Ubuntu both use ntpdate to synchronize the system time.
Install the ntp service from the source provided by wlnmp.
Add wlnmp source
rpm -ivh http://mirrors.wlnmp.com/centos/wlnmp-release-centos.noarch.rpm
Install ntp service
yum install wntp
Time synchronization
ntpdate ntp1.aliyun.com
