mysql start replication

replication works1, the first part of the process is the master record binary log. Master Records These changes in binary logging before each transaction updates the data. MySQL writes the transaction serially to the binary log, and when the event is written to the binary log completion,Master notifies the storage engine to commit the transaction. You can then receive slave requests.2, the next step isSlav

MySQL is an open source relational database system. Replication (Replication) is a process that replicates data from a MySQL database server (master server master) to another server (slave from the server). Configure Primary server (Master)1, edit the database configuration file my.cnf, generally in the/etc/directory.

There are many mysql cluster architecture methods, and different architectures are implemented according to different requirements. Simply put, mysql replication is the replication function of Mysql. The modes include master-slaves, master-slaves, master-slaves, and so on ca

Preface Mysqlreplicaion is a simple architecture, that is, a MySQL Server (slave) replicates logs from another MySQL Server (master), then parses the logs and applies them to itself.

The slave server needs to configure the security function on mysql5.6, which means the information is usually contained on the master server. Information or logs should be in a table. let's get started with configuration. Here is an example! First, you need to download the mysql test version. Click this link to download. We need a sandbox environment for the slave server and two master se
