In Centos6.3, the ntp time server-linux Enterprise Application-Linux server application information is implemented. For more information, see the following section. Network Time Protocol (NTP) is a standard Internet Protocol used for Time synchronization on the Internet. NTP
In the production environment, linux server time synchronization is important. The following describes how to build a time server.1. Set up a time server1. Install ntp server on a linux serverTar zxvf ntp-4.2.6.tar.gzCd ntp-4.2.6.
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
Preface a time error occurred on a self-managed Ubuntu 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 Protocol (NetworkTimeProcotol) aims to transmit unified and standard time on the Internet. The specific implementation scheme is to specify several
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.

Linux configuration NTP serverBackgroundWhen 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. Assume that a Linux machine time

2. Modify NTP profile via SSH

In a clustered environment and multi-server applications that require log synchronization, in order to ensure normal collaboration between multiple servers, it is necessary to keep their time consistent, and manually adjust the time on multiple servers is extremely unscientific, and this requires the use of NTP time servers to complete the synchronization of time. One, the installation of
When installing Cloudera CDH, it is required to install the NTP server to implement the time synchronization problem between different hosts. The following is a detailed introduction to the NTP installation process.First, the server-side configuration1, first install NTP
