, both of which are reasonable, but the two sides are not unified, resulting in replication error, MySQL from 5.1 to the current MySQL5.5 version of the problem (MySQL5.6 has not been tested, there should be the problem). Workaround: Service side use UTF8 character set encoding (due to the previous GBK, change to UTF8 will appear garbled and so many problems) Change application does not insert int field for non-int data Change app does not use prepare statement Binlog format

Recently, the team has a Data Synchronization requirement. Generally, two or more database (MariaDB) servers use the VPN channel to synchronize data with one database. First, they do not care about the VPN channel communication problem, this kind of multi-master and One-Slave Data Synchronization requirement has also been achieved through the replication function configuration of MySQL itself, but it does n

Implement Multi master Replication Using Stored ProceduresThe method is simple. The principle is: slave uses a table to save the masterfile and position of each master, and then uses the scheduler to traverse and change to different masters at intervals.Note the following: * The MySQL scheduler is disabled by default and needs to be manually enabled for dynamic
