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

Current network of the host, the business side sent to have an unsynchronized. Before also encountered similar problems, generally are NTP dead, resulting in the time is not synchronized. This view NTP service is operating properly. Www.111cn.net: ~ #:~ # RCNTP StatusChecking for Network Time Protocol Daemon (NTPD): R

Time synchronization is achieved through the NTP service.1: First build local Yum source URL (http://www.cnblogs.com/zxbdbk/p/6020679.html)2: First install NTP service[email protected] ~]# Yum install ntp-y3: Modify the NTP configuration file[Email protected] ~]# vi/etc/ntp.

/share directory of this machine. Check the time with the date command and find that it has become a normal local time: MonAug 13:14:29 CST (4)/etc/sysconfig/clock This profile can be used to set how the user chooses to display the time. If the hardware clock is local time, UTC is set to 0 and no environment variable

One, SELinux configurationIn order for Cloudstack to work properly, we must set the SELinux to permissive. It needs to be available in the current system running state and after it has been started, with the following configuration.To set SELinux to permissive while the system is running, execute the following command:Setenforce 0Configure the/etc/selinux/config file according to the following Lezilai to ensure that the current SELinux status is permissive. As shown in this example# This file co

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

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, di
