Master-slave replication is widely used in MySQL. it is mainly used to synchronize data on one server to multiple slave servers. it can be used for load balancing, high availability and failover, and backup. MySQL supports a variety of replication technologies, such as unidirectional, semi-synchronous, asynchronous, an

MySQL replication is established to achieve data redundancy based on business needs. MySQL 5.6.10 provides a more convenient gtid-based replication function. MySQL can automatically identify the last synchronization point through gtid, which greatly facilitates O M personne

In this section, we will learn how to grant user authorization and master-slave replication in Mysql.The following describes the advantages of Mysql master-slave replication:1. If a problem occurs on the master server, you can quickly switch to the service provided by the slave server.2. query operations can be performed on the slave server to reduce the access p
