MySQL Master-slave replication error: Incorrect usage of DB GRANT and GLOBAL privileges

When configuring MySQL master-slave replication, you want to pass

Grant replication slave on bbs.*-' BBS ' @ ' 192.168.1.3 ' identified by ' 123456 ';

To restrict the master-slave replication to only the BBS database, but the above statement will be error: incorrect usage of DB GRANT and global privileges because the level of replication slave is GLOBAL, So you can't just work on a database, but globally, as explained:

So still go through grant replication slave on * * to ' BBS ' @ ' 192.168.1.3 ' identified by ' 123456 '; and add/etc/my.cnf in binlog-do-db= BBS to limit the master-slave replication of the database for BBS
