Problems solved by technology

[0002] A distributed storage cluster system is generally composed of multiple servers to provide unified external services. In this paper, the server is represented by a "node". The traditional distributed cluster has its own web management system, including the client (Client) and the server (Server) It runs on the management node, so the database (DB) it maintains is usually updated on the management node and synchronized to other nodes periodically (for example, in a period of 30s); There will also be one or more standby management nodes. When the main management node fails (such as sudden power failure, downtime, etc.), it needs to switch to the standby management node immediately. However, the time of power failure is usually random and cannot be determined. At this time It may happen that the management node database has stopped running before it is synchronized. If the latest updated database information of the main management node before the power failure has not been synchronized to the standby management node, it has failed, and these database records may be lost due to inability to synchronize in time , leading to some unknown exceptions may occur after the management node is switched, causing some management flow risks, so the existing database synchronization method of distributed storage needs to be improved urgently

Abstract

The invention discloses a distributed cluster database synchronization method, device, equipment and storage medium. The method includes: the main management node persists the database information to the local system disk, and backs up the database information to the main management node BMC system through in-band communication; in response to the main management node BMC system detecting that the main management node fails or switches , then send the backup database information in the BMC system of the main management node to the backup management node; the backup management node uses the backup database information to update the database of the backup management node. The scheme of the present invention backs up the database information of the main management node to the BMC system of the main management node, and the backup management node uses the backup database information of the BMC system of the main management node to update the database of the backup management node, thereby preventing the loss of database information and effectively ensuring The reliability and integrity of the database information of each node reduces manual intervention and synchronization, and reduces maintenance costs.

Description

technical field [0001] The present invention relates to the field of distributed storage, and more particularly to a distributed cluster database synchronization method, device, computer equipment and storage medium. Background technique [0002] The distributed storage cluster system is generally composed of multiple servers to provide services to the outside world. In this article, the server is represented by "node". The traditional distributed cluster has its own web management system, including the client (Client) and the server (Server). It runs on the management node, so the database (DB) it maintains is usually updated on the management node and synchronized to other nodes regularly (for example, every 30s). There will also be one or more backup management nodes. When the main management node fails (such as sudden power failure, downtime, etc.), it needs to switch to the backup management node immediately. However, the time of power failure is usually random and cann...
