Abstract

The invention provides a method and device for creating a fragmented database cluster, and the method comprises the steps: obtaining the number of fragments, the number of copies and the memory specification which are currently used for creating the fragmented database cluster redis cluster, and numbering the fragments and redis instances in the fragments in sequence; determining the number M of physical devices required for creating the redis cluster according to the number of the fragments and the number of the copies; according to the memory specification and the number M of the physical devices, acquiring M physical devices meeting the memory specification from the resource pool, and numbering the M physical devices; and for each fragment, according to the numbering sequence of the redis instances and the numbering sequence of the physical devices, each redis instance is cyclically located on one physical device until the redis instances in all the fragments are located, and the created redis cluster is obtained. Through the method, the flexibility can be improved, and flexible and changeable application requirements are met.

Description

technical field [0001] The present invention relates to the technical field of database deployment, in particular to a method and device for creating a fragmented database cluster. Background technique [0002] With the development of enterprise information systems, fragmented database clusters are used more and more frequently. [0003] In the prior art, since redis is a single-threaded working mode, it only consumes a single-core CPU during work. Therefore, the business deployment requirements are realized through the mixed deployment mode of physical machines. However, in actual deployment, the mixed deployment mode of physical machines is relatively fixed. For each different combination, the required number of physical equipment and placement methods need to be set in advance, which lacks flexibility and cannot meet flexible and changeable application requirements. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a m...
