Abstract

The invention relates to the field of cloud storage, and discloses a method and a device for data synchronization based on a cluster server system. The method comprises the steps of dynamically electing a master node, and notifying the master node to process in a cluster after worker nodes receive a task, thereby effectively ensuring the data consistency, avoiding mutual exclusion and synchronization between processes of the nodes at the same time, and reducing the system overhead. According to the invention, the cluster server system comprises at least one cluster, the cluster comprises at least three nodes, and the method for data synchronization based on the cluster server system comprises the steps that one node in the cluster is dynamically elected as the master node, and the other nodes act as the worker nodes; if the worker nodes receive a task request, the other nodes in the cluster are notified to process the task; each of the other nodes in the cluster judges whether the node itself is the master node or not after receiving the notice; and if the node is the master node, the master node processes the task and feeds back a processing result.

Description

technical field [0001] The invention relates to the field of cloud storage, in particular to a data synchronization technology. Background technique [0002] In practical applications based on cloud storage technology, cluster technology is usually used to form a loosely coupled set of computing nodes with two or more computer nodes, which provides users with more efficient fault tolerance and recovery capabilities, and increases the ability to The real-time processing capability of massive tasks provides better reliability and practicality. [0003] In the cloud storage system, multiple servers are formed into a cluster by using cluster technology, and the cluster provides external services through a cluster virtual IP address (Virtual Internet Protocol, "VIP" for short), and the platform communicates with the cluster system through the unique cluster VIP , all servers in the cluster can receive and process requests sent by users, which greatly improves the ability to resp...
