central time ntp server

Chrony is an open source free software that keeps the system clock synchronized with the clock server (NTP) to keep time accurate.It consists of two programs: Chronyd and CHRONYC.Chronyd is a daemon that runs in the background to tune the system clock and clock server synchronization running in the kernel. It determine

Recently, we often encounter some faults caused by synchronization of time on each server. Now we need to build a CentOS time server to adjust and upgrade the ntp time package. # The specific configuration of yum-yinstallntp has b

Encounter a situation, that is, the time between multiple servers is not synchronous, and some are fast slow, this time will need to use the network,Log on to the server, enter the command date can query the server time, need to synchronize the

The time synchronization centos command must be the same for multiple servers. one of the servers must be used as the time server, and the other servers must be updated on a regular basis. 1. run the following command to install ntp on the time

1. Select one of the servers as the benchmark server, which provides the clock service. (1) First determine if NTP exists, and if it does not exist, install it by using the following command: Yum Install NTP (2) Modify the configuration file/etc/ntp.conf in which to insert: Restrict 192.168.20.0 mask 255.255.255.0 nomodify notrap which With restrict control autho

For multiple Linux servers, it is necessary to keep the time consistent. According to the accuracy requirements, there should be a corresponding time interval for time synchronization. If you do not synchronize time, long time will be very different, when the problem is diff

The newly installed CentOS system server may have set the wrong time, time is very important when doing the cluster, it is likely that the cluster will fail because of the time, so you need to adjust the time zone and adjust the times. The following is a CentOS system that u

If we use the U.S. VPS Host Station we will find some VPS, some sites submitted time and we are different, the adoption of the United States time, rather than the Beijing time we need, this problem is mainly due to the current VPS system time zone settings problem. We need to manually adjust to solve the problem. Firs
