Abstract

The invention discloses a distributed cluster time synchronization method and device and a computer readable storage medium, and relates to the field of computers. The method comprises the following steps: receiving a Tick request instruction sent by a service node and determining a current Tick; new Ticks with the corresponding number are generated according to the number of the instructions for requesting the Tick, and 1 is sequentially added to the new Ticks on the basis of the current Tick; and sending the new Tick to the corresponding service node according to the order of receiving the instruction for requesting the Tick. Through adoption of a logic clock mode, time synchronization of interaction of each service node is achieved, and the problem of data asynchronization in a cluster is avoided.

Description

technical field [0001] The present application relates to the field of computers, and in particular, to a distributed cluster time synchronization method, apparatus, and computer-readable storage medium. Background technique [0002] A distributed system is a software system built on a network with a high degree of cohesion and transparency. In distributed systems, time synchronization is often a headache. Generally speaking, time is an absolute quantity, but when it is specific to each computer, time is a relative quantity. There are slight differences in the time of each node in a distributed system, which is also unacceptable for a highly concurrent distributed cluster. Once the time of many time-related middleware is out of synchronization, the data of each module in the cluster will be out of synchronization, such as the timing failure of the Remote Dictionary Server (Redis). [0003] Traditional time synchronization using a physical clock such as a Network Time Prot...
