First, MySQL master (called Master) from (called slave) Copy principle: (1). master records data changes to the binary log (binary log), which is the Log-bin specified file (These records are called binary log events binary log event)(2). Slave copy Master's binary log events to its relay logs (relay log)(3). Slave redo the event in the relay log, changing the data that reflects it (the data repeats itself) Attached schematic diagram: Second, the
