ntp server configuration in linux

NTP server is used for LAN time synchronization. You can ensure that all servers in the LAN are synchronized with the time server. Some applications require a higher time-to-live nature. Requirements must be unified time, so the configuration of the time server is important.

Configuring NTP to set up the local time server NTP is a protocol used to keep the system and a precise time source at time. in Linux, we can use the Network Time Protocol to keep our system accurate. install: # Yum install NTP or find the ntp rpm package from the installati
