NTP synchronization server timeCurrently, the NTP service is not widely used. Recently, a DB2 cluster has some requirements on time consistency, So I thought about NTP. Although timed can also be used, it is only valid for broadcast domains,

To ensure consistency within the cluster, the NTP time synchronization server needs to be configured, using the China National Time Service Center clock synchronization server, p address 210.72.145.44. So each machine in the cluster is synchronized with the 210.72.145.44 clo

, hosts using NTP should interact periodically with the specified NTP server to keep their clocks synchronized. Time synchronization between different hosts is important for scheduling backups, intrusion detection records, distributed task scheduling, or transactional order management. It should even be part of a day-

The time for all nodes must be synchronized, which is usually achieved by configuring the NTP server. If the user already has a time server in the network, then all nodes can point to it, otherwise you can pick a node from the cluster as the time server and let the other nodes synchronize with it. These two methods are

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

Network Time Protocol (NTP, Network Time Protocol) is used to synchronize all of its client clock services. The NTP server synchronizes the clock of the local system with a public NTP server and then serves as a time host so that all clients on the local network can synchron

/share directory of this machine. Check the time with the date command and find that it has become a normal local time: MonAug 13:14:29 CST (4)/etc/sysconfig/clock This profile can be used to set how the user chooses to display the time. If the hardware clock is local time, UTC is set to 0 and no environment variable TZ is set. If the hardware clock is UTC time, set UTC to 1 and set the environment variable TZ (or configuration file/etc/tz) as time zone information, such as "Asia/shanghai". The
