SYN2136 type Beidou NTP network time serverProduct OverviewSYN2136-type Beidou NTP network time server is designed by Xi ' an synchronous Electronic Technology Co., Ltd., self-developed and produced a time server based on the NTP/

will not be adjusted with NTP. The concept of Clock_realtime_coarse and Clock_monotonic_coarse is similar to the concept of clock_realtime and clock_monotonic, except that the accuracy is a rather coarse version. Sometimes, the timer doesn't have to require that much precision, so we can use this clock to get better performance. Clock_boottime and Clock_monotonic are similar, but also monotonous above, whe

Configure NTP and synchronize server time Configure NTP and synchronize server time There are more and more servers in the project. Recently, Database Synchronization has been performed on several servers. When a synchronization error occurs, you can view the logs, as a result, we found a small problem that has been ig

Configure NTP to synchronize server timeMore and more servers in the project, and recently in a few servers to synchronize the database, synchronization error to look at the log, and then found a small problem has been neglected---several servers time inconsistent.The data is then consulted, and the decision is made to use NTP (Network

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

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
