Note: my.cnf in the binlog-do-db= library name, when the library changes, the corresponding changes from the library, that is, the main from each of the two libraries to use this parameter to name the corresponding phase from the synchronization of the library, and to the main note if you want more than one library, but also have multiple binlog-do-db parameters
