ntp server configuration in linux

Machine Networking:If the server can be networked: Perform ntpdate 1.cn.pool.ntp.org the server will automatically synchronize time write a scheduled task to perform a time synchronization every two minutes;Crontab-e/2 */usr/sbin/ntpdate 1.cn.pool.ntp.org//So that time synchronization can be achievedThe following is a domestic NTP Server1.cn.pool.ntp.org2.cn.poo

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, NTP is more powerful. Configura

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 -- enable-parse-clocksmake am In the production

On AIX 6.1, the NTP clock synchronization configuration details ntp synchronization server time NTP service is currently used in a small number of projects, recently a DB2 cluster, there are some requirements for time consistency, so I wantNtp. Although timed can also be use

An error is displayed when you use RHEL as an NTP server to update ntpdate on the server. My configuration is as follows: restrict127.0.0.1restrict-6: 1restrict10. Conflict An NTP server is built using RHEL. An error is displayed

1, install NTP service, to use time synchronization, then the server and client need to use the following command to install the NTP package [root@5201351 ~]# Yum Install ntp-y 2, if only as a client, the configuration can be very simple, edit the/etc/ntp.conf f

This experiment uses 2 Rhel 6.3, of which 192.168.1.131 is the service side; 192.168.1.132 is the client. Server-side configuration allows only 192.168.1.0 network segments to connect to servers for time synchronization1. Install the NTP service (client and server side)# yum-y Install

NTP server ConstructionNTP is a time server that provides the Synchronization Update time of other computers, so that the time of each computer is the same, without any deviation due to the long running of the system. The client also needs to install the NTP service.1. Install NTP
