how to configure ntp server in linux

In the production environment, linux server time synchronization is important. The following describes how to build a time server. One slave build time server 1、install ntpservertarzxvfntp-4.2.6.tar.gz cdntp-4.2.6./configure -- prefix =/usr/local/ntp -- enable-all-clocks --

Two ways to synchronize NTP: 1. Synchronize directly with the Ntpdate command 2. Smooth sync with NTPD serviceThe defect of the direct synchronization method: It will cause the scheduled task to be done again.The offset of the synchronization time of the smooth synchronization is not too steep, according to the offset, the mean variance equivalent of each synchronization a little bit, synchronization fully synchronized well takes a long time. So gener

This article describes in detail how to configure the NTP time synchronization server, and takes CISCO 7200 as an example. I hope this article will help you. For the purpose of network management, we set up netflow to monitor traffic and obtain detailed access records for Intranet users to access the Internet. Such records can be accurate to seconds, the premise

. Regardless of the time that we want to sync the system through any channel, the provider will usually give only the utc+0 time value and not the time zone (because it doesn't know where you are). So when we set the system time, it's the first thing to do # date Thu Oct 11:22:45 EDT 2013 If the time zone is found to be incorrect, the method of modification is shown in Appendix 1 2. Check that NTP is installed # Rpm-qa |grep ^
