Abstract

The invention provides a cluster time synchronization method, a cluster and a time synchronization system. The method comprises the step of selecting at least one node in a cluster as a server node, configuring the other nodes as client nodes, and configuring time synchronization addresses for the client nodes according to the address of each server node. The method also comprises the step of sending a first synchronization request to an external time server by the server node and receiving standard time sent by the time server; carrying out synchronization on own clock by the server node according to the standard time; sending second synchronization requests to the server node by the client nodes according to the configured time synchronization addresses; feeding back current time corresponding to own clock to the corresponding client nodes by the server node according to the received second synchronization requests; and carrying out time synchronization by the client nodes according to the current time fed back by the server node. According to the scheme, the time synchronization efficiency can be improved.

Description

technical field [0001] The invention relates to the field of cluster technology, in particular to a cluster time synchronization method, a cluster and a time synchronization system. Background technique [0002] As the amount of information data increases, the scale of big data clusters is also increasing. A large amount of business data is stored on each node in the cluster, so the consistency of the cluster time is very important. At present, the time synchronization of each node is mainly performed manually. However, the existing technology is only aimed at clusters with a small number of nodes, and is not operable when the number of nodes in the cluster is large. Therefore, it is urgent to propose a cluster time synchronization method to quickly realize time synchronization within the cluster. Contents of the invention [0003] Embodiments of the present invention provide a cluster time synchronization method, a cluster and a time synchronization system, so as to qu...
