replication, we understand basic information about the binary log files of the master server, which must be used in slave server settings, this information includes the name of the binary file of the master server and the location of the current log record, so that the slave server can know where to start the replication operation. You can use the following oper

The copy operation is done through 3 threads during the MySQL replication process: Where the Binlog dump thread is on the main library, I/O threads and SQL threads are on the slave library, and when replication starts from the library (start SLAVE), the I/O thread first connects to the main library, which is
