Set up ntp time server and ntp Time Server Chapter 1 Introduction to ntp1.1 ntp NTP(Network Time Protocol) is a Protocol used to synchronize Time between computers in the Network. Its purpose is to synchronize the computer clock to the Coordinated Universal Time UTC, and its accuracy can reach 0.1 ms in the LAN. In

1. "The NTP socket is on use, exiting" error appears. The reason for this is that the system NTPD server is running and can be via PS aux | grep ntpd View, if you still want to manually synchronize time, you must first stop the service, the command is:service ntpd stop or/etc/init.d/ntpd stop2. Npdate time.windows.com or ntpdate us.pool.ntp.org will be able to synchronize time successfully. This article is from the Linux Technical Exchange blog, so b

Deploy NTP in RHEL6.5 Cluster NTP is called Network Time Protocol, which is the Network Time Protocol. It is generally used in Linux to synchronize the time of different machines in the cluster.

Linux uses NTP service to manage/Synchronize server time When there are multiple Web servers, and each server's time needs to be consistent, consider using NTP services. 1. Use Ntpstat to see the current status of the NTP service. #ntpstat If the output below, the description has not started, you need to set the server restart when the

Automatic synchronization via network NTP If you only need to sync once, execute the following command Rdate-s time.nist.gov Where time.nist.gov is a time server, of course you can also use another time server. If multiple servers require a full synchronization of time, it is best to configure these servers with a unified, automatic synchronization task, so that their time is biased for a variety of rea
