Problems solved by technology

[0004] However, in the above implementation method, after adding new nodes to achieve capacity expansion, in order to achieve data balance, a lot of data will be migrated between nodes in the cluster system
It takes dozens of hours for the cluster system to rebalance the data. If a network failure or node failure occurs at this time, the log information will be unrecoverable
Therefore, the cluster management method in the prior art results in poor reliability of the cluster system

Abstract

One embodiment of the invention provides a cluster management method and a cluster server. The method comprises following steps: determining whether new sub-cluster are added; if newly added sub-clusters are determined by a cluster server, then switching at least one data acquisition client terminal connected to the original sub-clusters to connect to the newly added sub-clusters; the method realizes that the data acquisition client end connected to the original sub-clusters are directly changed to be connected to the newly added sub-clusters by the cluster server during expansion by newly adding nodes in a cluster system. Because the data between sub-clusters does not communicate with each other, the sub-clusters working as a complete cluster can work independently. Therefore, after the capacity expansion, the data between the sub-clusters does not migrate, thereby improving the reliability of the cluster management method.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a cluster management method and a cluster server. Background technique [0002] With the development of communication technology, more and more log information is generated by servers, and the data volume of daily log information can reach TB level. Therefore, a unified log platform is needed to collect log information of more than a thousand servers. A distributed cluster system can be used to process log information. [0003] A cluster system in the prior art includes at least two nodes, and each node can store data fragments of log information. Each data shard can have one backup. The primary data and backup data of the same data shard cannot be stored on the same node. figure 1 It is a schematic structural diagram of a cluster system in the prior art. Such as figure 1 As shown, the primary data of data fragments 0, 1 and 2 are stored on node 1: P0, ...
