MySQL master-slave replication and read-write separation, mysql master-slave read-write The so-called read/write splitting is to prepare two types of MySQL Databases in advance, one for update (master) and the other for query (slave ). When the application system needs to update data, it calls the master and slave when

use a binary log and set a unique ID number.On each slave server, you must set a unique ID number in order to connect to the Maste server(optional) Create an independent user to authenticate the primary server and replicate by accessing the binary logBefore you create a data snapshot or start the replication process, you need to log the master server's binary log location. This information is required at late slave startupIf data already exists on th

MySQL parallel replication is already a commonplace. I started to deal with this issue online since 2010. I have been happy to share it for the first two or three years.

Recently, when I deployed The MySQL master-slave replication architecture, I encountered "Last_IO_Error: Fatal error: The slave I/O thread stops because master and slave have equal MySQL server UUIDs; these UUIDs must be different for replication to work.

Use XtraBackup for MySQL master-slave replication without locking tables Xtrabackup is an open-source project of percona to implement the innodb Hot Backup function similar to InnoDB's official Hot Backup tool. It can quickly back up and restore MySQL databases. Xtrabackup contains two tools: Xtrabackup is a tool used

You need to understand why your replication behavior lags behind, and then learn how to use the correct method to solve the lag problem. MySQL replication is generally considered very effective. after the master server makes changes, the slave server can make the corresponding changes within several seconds. However, if the synchronization between the two is s
