When a program runs on multiple servers, the clock on these servers is sometimes the same. However, when the server runs for a certain period of time, the clock on each server may be different, in this case, all servers need to automatically calibrate their respective clocks. NTP is a convenient clock service, which can be used for clock

This paper introduces two kinds of protocols commonly used in time server: SNTP and timing, and explains the setting of Linux Time service in LAN environment, and finally realizes the synchronization and calibration of all computer clocks in the whole LAN environment. 1, what is the network Time service Network Time service net Times services and network file download service FTP, Web browsing services www,

Internet that can provide us with accurate time and then synchronize our system time with a protocol, then this Protocol is NTP. Note that all we have to say about synchronization is the synchronization between the system time and the network server.4. Preparation before setting up

I. Introduction Network Time Protocol (NTP) is used to synchronize time between the distributed time server and the client. NTP is transmitted Based on UTP packets. The UDP port used is 123. NTP is used to synchronize the clock of all devices in the network, so that all devices in the network are consistent with the c

Time synchronization in a cluster can cause big data applications to run into confusion, causing unpredictable problems, such as HBase, which hangs when time differences are too large, so in a big data cluster, the NTP service should serve as a basic service, as shown below in the CentOS 7.2 Procedures for configuring NTP services on ClustersFirst check if the

The NTP clock synchronization configuration on AIX6.1 describes the ntp synchronization server time. Currently, the NTP service is not widely used. Recently, a project, DB2 cluster, has some requirements on time consistency, so I

1th. NTP time server Setup 1.1ntp Introduction NTP (networktime Protocol, 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 . The importance of time synchronizationTime synchronization can ensure the normal operation of the business, such as data synchronization, such as the batch execution of the system planning task. such as2.
