Network time Protocol (NTP) is also a new exam requirement for RHCE. Study time also by the way to review how to set up Linux time, now take out and share with youSetting up an NTP server is not difficult, but NTP itself is a very complex protocol. Here's just a brief introduction to the practical approachLike last tim
How to build an NTP server in CentOS The Network Time Protocol (NTP) is used to synchronize the system time of different hosts on the network. All Hosts you manage can synchronize their time with a specified time server called NTP server
NTP (Network time Protocol) server: Temporal serverGMT (Greenwich Mean time,gmt time): Greenwich Mean TimeSummer saving time (or daylight saving time): Daylight savings (DST)UTC (coordinated Universal time): Concord Standard TimesThe most standard time is calculated by atomic clocks, according to the Atomic Oscillation cycleUTC and GMT time are 16 minutes apart due to different timing methodsSoftware Clock:
Preface a time error occurred on a self-managed server, which caused a problem in the display time of mail sending, here we will take the time to record the process of building an NTP server. The Network Time procotol (NTP protocol) aims to deliver a unified and standard time on the Internet. The specific implementatio

The NTP server----operation of the Linux real-World Deployment series explains how to deploy a load-balanced and highly available NTP server under a simple architecture. Next, we need to understand the maintenance of the technology, so as to better escort the company's business AH.
Network Time Protocol (NTP) is a standard Internet Protocol used for Time synchronization on the Internet. NTP is used to synchronize computer time to certain time standards. The current Time standard is Universal Time Coordinated ). The primary developer of NTP is Professor David L. Mills from the University of Delaware. What is the use of
recently, found that the company domain member user time and the domain server time is not synchronized, to achieve: 1, the domain member server and intra-domain client and domain NTP server synchronization, 2, the domain NTP server

Last time I talked about how to adjust the Linux system time. In the project, we often need to view system logs when analyzing system problems. In this case, if a cluster or ha application is used, the time is very important for locating the sequence and cause of the problem. Therefore, we hope to have a way to ensure that the time of the two servers is the same, and it is best to achieve the standard time. This is what it means to build an NTP
ObjectiveIn the world of computers, time synchronization is extremely important for co-ordination between computers, and it takes time to synchronize our high availability clusters, load balancing, DNS services, and so on. NTP (Network time Protocol) is a protocol 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

The Linux Combat Deployment series of NTP server----theory to introduce the concept of time and the principles of NTP, this blog will bring you to deploy a production environment to achieve simple load balancing and highly available NTP server. Simple architecture Diagram:
Build an NTP server in Linux BackgroundWhen there are too many servers, it is a big problem whether the time is accurate or not. Although this problem is always ignored, it is necessary to unify the time. The following describes how to configure the Linux time server in the LAN. For example, if the IP address range is 50.50.50.0/24, the IP address range is IP50.5
