Abstract

The invention relates to a database management control method and system and a storage medium, and under the condition that the main node is connected with at least two slave nodes, the method comprises the steps that a slave node detects the network connectivity of a main node and transmits first error information under the condition that the network connectivity is abnormal; the slave node detects a synchronization state between the node and the master node, and sends second error information under the condition that the synchronization state is abnormal; under the condition that all the slave nodes send out the first error information and the second error information, it is determined that the main node breaks down, and the main node and any slave node are switched. Through the application, the problems that the main database server is easy to switch by mistake and the external application cannot be normally accessed under the condition that the main database server is down are solved.

Description

technical field [0001] The present application relates to the field of database management, in particular to a database management control method, system and storage medium. Background technique [0002] With the improvement of relational database management system, relational database management system has been widely used in various industries as commercial software. MySQL is a relational database management system. The cluster mode of MySQL is master-slave synchronization. MySQL has a master database server and a slave database server. When the master database server is down, MySQL needs to switch to the slave database server. At present, there are two main ways to switch the master database server to the slave database server. One is to manually change the IP address of the master database server in the application configuration file to the IP address of the slave database server. The IP address of the master database server in the configuration file is changed to the I...
