Configure The ntpd Service Properly

In the cluster scenario, the time of servers must be accurate and consistent. For example, if the server time is inconsistent, the data generated by different servers may be sorted or compared inaccurately. Even if you run the date command to set the time of all servers to the same value, the tim...
