There are 3 main steps to the MySQL replication function The primary server logs changes to the binary log (these are called Binary log events)Copy the primary server's binary log events from the server to its trunk logRedo the events in the relay log from the server.The first part of the process is that the primary server records the binary logs, and before each transaction updates the data is completed,Master logs These changes in binary logging, an

I. Principles of MySQL master-slave Replication 1. mysql replication process: each time a write operation is executed, it will save a copy to its own database. At the same time, this write operation will also be stored in a binary log file, and save them as events. Therefore, each write operation or modification operation on the front-end data in this database will save an event, we will send the event to a

First, IntroductionIn the master-slave copy of the previous article: http://www.cnblogs.com/lay2017/p/9043985.htmlWe learned that MySQL writes logs through master, slave reads and executes the log content to achieve slave data consistent with master. So based on this principle, we can realize the replication function of two master.Broadly as follows:1, both master open Log-bin write log2, ID to repeat3. Configure the tables to be copied4, two master r

Master-Slave replication principle MySQL replication is an asynchronous replication process that replicates from master to one or more slave. The entire replication process between master and slave is done primarily by three threads, one IO thread on the master side and two threads (SQL thread and IO threa
