Abstract

The invention provides a data synchronization method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining the working state of a current database; determining whether the current database has a fault or not according to the working state of the current database; under the condition that the current database fails, selecting a targetstandby database from a plurality of standby databases; setting the current database as a standby database, and setting the target standby database as a new current database; and creating a databasesynchronous replication service and an external replication service for the new current database. According to the technical scheme, the service application of the railway passenger ticket system is completely not affected by database faults occurring in the background, the user experience is improved, meanwhile, the data synchronization performance of the whole railway informatization system is achieved, and the stability and safety of the whole railway informatization system are maintained.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of computer technology, in particular to a data synchronization method and device, electronic equipment, and a computer-readable storage medium. [0003] 【Background technique】 [0004] With the development of railway construction and the deepening of railway service reform, railway informatization has been widely used. With the operation of 12306 and other systems, China's railway information technology, like China's high-speed rail technology, has entered the forefront of technology. [0005] Among them, the railway ticket system is based on PostgreSQL optimization and customization to form an independent database. PostgreSQL is a free object-relational database server (database management system), which provides Another option for . Since the application of multiple systems such as catering system, point system, face service system, QR code service system, and standby system all rely on the databas...
