Distributed storage high-reliability data log module and construction method thereof

The invention discloses a distributed storage high-reliability data log module and a construction method thereof. The method comprises the steps that a log module with a master-slave structure is set,and the master-slave structure comprises a master log module and a slave log module; an NVDIMM is adopted as log storage equipment, and a plurality of partitions are created in the NVDIMM; the NVDIMMis equally divided into partitions with the same number according to the master-slave structure, and mapping relationships are bound one by one; when affairs on the main log module are recorded intothe corresponding NVDIMM partitions, the affairs are also recorded into the corresponding NVDIMM partitions of the slave log module, and the partition parts of the same affair records in all the partitions form a log group; according to the method, the master-slave structure of the log module corresponding to the NVDIMM is used, so that the safety and reliability of a log file are improved, and acrucial role is played in gu
