Abstract

The invention discloses a method and a device for carrying out fault repairing on a database management platform. The method for carrying out the fault repairing on the database management platform, provided by the embodiment of the invention, comprises the steps of judging a role of a fault database instance in an instance group before fault when a repairing command on the fault database instance in the database management platform is received; judging whether a switching record corresponding to the fault database instance can be obtained from a saved switching record table or not when the role of the fault database instance is a main database; establishing a master-slave relation between the fault database instance and a current main database in the instance group by utilizing the switching record when the switching record of the fault database instance is obtained, carrying out synchronous operation of the fault database instance and the current main database, and making the fault database instance online when an online condition is met.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a fault recovery method and device for a database management platform. Background technique [0002] The MySQL database has been serving Internet companies for ten years. Among many relational database products, the storage engine characteristics of MySQL make it gradually become the data storage medium of choice for various business models. [0003] Initially, the amount of data is still in a small stage. MySQL provides application access in the form of a single instance service that shares a server with the application. When the server has a hardware failure, or the application and MySQL compete for resources, the MySQL resource is exhausted. Crash, or the various restrictions of the low version at that time caused MySQL to run abnormally. At this time, DBA (Database Administrator, database administrator) manual intervention is required to restore the data using the pre-saved...
