Abstract

The invention provides a database read-write method, server and system, electronic equipment and a non-instantaneous computer storage medium. A database is configured in the server, and the database comprises a main database and at least two standby databases; the main database and the at least two standby databases are used for library writing operation and library reading operation; the librarywriting operation comprises the following steps: detecting the state of a main database; according to a detection result, sending the library writing request to the main database or one of the at least two standby databases; the library reading operation comprises the following steps: detecting the states of at least two standby databases; and sending the library reading request to at least one ofthe at least two standby databases according to the detection result. When the database fails, the technical scheme of the invention can automatically switch the database, and the client does not perceive the database, does not need any modification, and is directly connected to a new database.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a method for reading and writing a database, a server, a system, electronic equipment and a non-transitory computer storage medium. Background technique [0002] The reliability and security of the database directly affect the safe operation of the platform. Currently, there are three high-availability solutions for the database in the process: [0003] (1) RAC (Real Application Clusters): Multiple servers form a shared Cache, and these servers share a network-based storage. The system can tolerate single and / or multi-machine failures. However, multiple nodes within the system need high-speed network interconnection, basically everything needs to be placed in a computer room, or in a data center. If there is a failure in the computer room, such as a network failure, it will be broken. Therefore, only using RAC still cannot meet the important business needs of general Inter...
