However, this is not enough to meet the security needs of the enterprise. The following is an explanation of NTP's main configuration file settings. 1) Resolution of the

Linux NTP service configuration for Oracle RAC tutorial, ntprac When installing Oracle 11g RAC, We need to configure the ntp service. There are many ways to configure the clock synchronization mode when using virtual machines. You can use the clock synchronization feature provided by vmware or directly use a local node as the time

Configure the NTP server and Heartbeat V1 for httpd High Availability Establishment and use of NTP servers In high-availability clusters, the time requirements for each node are strict. Therefore, we need to configure an NTP server to implement the time synchronization of hi

The time for all nodes must be synchronized, which is usually achieved by configuring the NTP server. If the user already has a time server in the network, then all nodes can point to it, otherwise you can pick a node from the cluster as the time server and let the other nodes synchronize with it. These two methods are

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

The NTP server "Network time Protocol (NTP)" is used to make the computer Time Synchronization protocol, which is negotiated with a specific algorithm through UDP packet Exchange , allows the computer to synchronize its server or clock source (such as quartz clocks, GPS, etc.) to provide a high-precision time correctio

On the basis of the Linux system after installation--based on CentOS (5.8/6.4)--we mentioned how to automatically update the server time at timed intervals. Also mentioned, when the number of intranet machines, if all go to the public network NTP server synchronization time is there will be delay. Of course, this is not just the only meaning of deploying an
