This article mainly introduces how Yii implements master-slave read/write splitting for multiple databases. it is a very practical technique to implement the separation of master-slave read/write for multiple databases by extending the Yii database class, for more information about how to implement master-slave read/write splitting for multiple databases in Yii,

I also hope you can make a brick and write it using PhP5. PhP4 for fear that I am falling behind.Copy the PHP content to the clipbo

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
