Problems solved by technology

However, the synchronization of the database and files in this way is independent of each other, which may cause inconsistencies between the database and configuration files, and in some applications that interact with the underlying system, those interactive actions cannot be synchronized, resulting in inconsistencies between the two servers, hot standby Some features don't work properly after switching

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, the present invention is based on the mysql binlog, triggers the synchronous action through the mysql sql operation, and uses the configuration file to flexibly control the synchronous table and the data requiring special processing. The specific implementation steps are as follows:

[0022] Step 1: Configure binlog on both server A and server B to be synchronized, and configure them as hosts; use the logfile file to store the file name of the current binlog, and the logpos file to store the location of the current binlog. Configure the tables that need to be synchronized and the tables that need special processing in the configuration file.

[0023] Step 2: Initialize between server A and server B, so that the two hosts are in the same initial state;

[0024] (2.1) Server A packs the tables, confi...

Abstract

The invention discloses a binlog-based configurable mysql database real-time synchronization method. The method is triggered on the basis of a mysql action event, and interactive action of a user among a database influencing configuration operation of a system, a configuration file and an underlying system on a page can be all executed by a backup server in one mysql action event, namely that a certain action of the user done at a main server can be completely copied to the backup server in real time. Consistent configuration of two servers in hot standby is guaranteed, service can be normally provided after switching, and the reliability and stability of the system are improved.

Description

technical field [0001] The invention relates to the field of data synchronization, in particular to a binlog-based configurable mysql database real-time synchronization method. Background technique [0002] Hot standby is a disaster recovery method for servers, and it is a backup form of servers. When the main server fails, the system automatically activates the backup server to complete the service switchover. Therefore, the configuration between the two servers should be synchronized. Although mysql provides a database replication function, which can realize the synchronization of two databases, there are also many file synchronization software that can synchronize files. However, the synchronization of the database and files in this way is independent of each other, which may cause inconsistencies between the database and configuration files, and in some applications that interact with the underlying system, those interactive actions cannot be synchronized, resulting in i...
