" now we know how to set the system and hardware time. but the question is, what should I do if neither of these two times is accurate? Then we need to find a server on the Internet that can provide our accurate time and then synchronize our system time through a protocol. Then this protocol is NTP. note that next we will talk about synchronization between the system time and the network

Configure NTP, synchronize server time, and configure ntp synchronization server Configure NTP and synchronize server time There are more and more servers in the project. Recently, Database Synchronization has been performed on se

, they sometimes need to work together, so accurate time reliability is particularly important. The configuration and use of the NTP service are very simple, and the network information used is very small. NTP time servers are widely used in network security, online teaching, database backup, and other fields. It is important for an enterprise to take measures to

1th Chapter ntp1.1 NTP IntroductionNTP, Network Time Protocol, is a protocol that is used to synchronize the time of each computer in a network. Its purpose is to synchronize the computer clock to the World coordinated UTC, its accuracy in the LAN up to 0.1ms, in most places on the Internet its accuracy can reach 1-50ms.1.2 NTP server-side deployment1.2.1Environm

NTP (Network Time Protocol) is by David L. professor Mills proposed in 1985 that in addition to estimating the round-trip latency of packets on the network, it can also independently estimate the Computer Clock Deviation, so as to achieve high precision computer calibration on the network, it is a communication protocol designed to enable different machines to maintain the same time on the Internet.
