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 thought about ntp, although timed can also be used, it is only valid for broadcast domains

[Switch] Provision of time synchronization and NTP service for FreeBSD system China National Time Service Center Time Server IP Address: 210.72.145.44 Http://www.cnfug.org/journal/archives/000038.html Original article of NTP at www.cnfug.org: Tonight If you ignore the computer time, there will be an error soon.This error is reflected in the time stamp of the email sending time, and in the posting

The/etc/linux ntp.conf system-config-date network Time Protocol (Linux NTP, web-hour protocol) is used to synchronize all of its client clock services. The Linux NTP server synchronizes the clock of the local system with a common Linux NTP server and then serves as a time host so that all clients on the local network can synchronize clocks.The biggest advantage o

Time synchronization is important when the Linux service needs time-stamping.

Configuration of the CentOS6.5 NTP service The first requirements are as follows: There are three servers, respectively: hadoop01.shiluo.com 192.168.239.133 Hadoop02.shiluo.com 192.168.239.134 Hadoop03.shiluo.com 192.168.239.135 Now to synchronize the time of the other two machines with the time of hadoop01.shiluo.com this machine, all of the following steps are tested effectively, and there are problems to communicate. 1. Configure hadoop01.shiluo.

The server is very time-critical, the generation of Linux server files, logs, and database connections are based on the logic of timeTask processing, if the time is not synchronized, then, the processing of the task, and the analysis of the problem log, the time is wrong, difficult to analyzeDirectly change the Linux server time, the impact is particularly large, we all know that the server farm startup is regular, if you arbitrarily change the Linux server timeis likely to cause time logic stat

The author needs to face the environment for time synchronization has a higher requirement, and the virtualized environment time is more prone to problems, you can refer to the previous blog post Why is the synchronization on the domain controller very important? The author of the environment, after personal observation, if there is no time synchronization, virtual machine and standard time gap in just two hours unexpectedly on the deviation of nearly half an hour! According to VMware KB 100306

BackgroundWhen the server is more, time is accurate or not, the same is a big problem. Although this problem is always overlooked, it is necessary to unify the time. Here's how to configure a Linux time server within a LAN.Configuration of the environment and requirements:1.
