Embodiment Construction

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] Such as figure 1 Shown is a schematic structural diagram of a data server cluster system provided by an embodiment of the present invention; the system includes a master server 10 and at least two slave servers 20 connected through a network, wherein:

[0037] The main server 10 is used to receive the data sent by the client, number the data, and broadcast the numbered data to the slave server 20; it is also used to receive confirmation information that more than half of the slave servers 20 receive the numbered data Afterwards, broadcast the st...

Abstract

The invention discloses a data server cluster system and a data synchronization method. The data synchronization method includes the steps that data sent by a client side are received by a master server and then numbered, the numbered data are broadcasted to a slave server, after the master server receives more than half of confirmation information of the numbered data received by the slave server, storage data commands are broadcasted to the slave server, and the master server and the slave server store the numbered data to local. By the adoption of the data server cluster system and the data synchronization method, the single-point problem of a traditional master server and a traditional slave server is solved, meanwhile, uniformity of cluster data is guaranteed, and reliability and availability of clusters are improved.

Description

technical field [0001] The invention relates to the field of computer and network information technologies, in particular to a data server cluster system and a data synchronization method. Background technique [0002] In the cloud storage system, the metadata server stores all the metadata of the file system, so the reliability and expansion of the server are important functions. Generally, there will be a cluster of multiple metadata servers to store data and provide read and write services at the same time. , therefore, how to ensure the data consistency of the cluster is an important issue. [0003] At present, the traditional master-slave structure server architecture usually has a master server with multiple slave servers. The master server is responsible for reading and writing, and the slave servers can only read. If the main server is manually reconfigured, the system cannot provide services for a period of time, and the reliability is low. Contents of the invent...
