>From the mySQL Replication docs... snip -------------------------------------------------------------- In Version 3.23.15, all of the tables and databases will be replicated. Starting in Version 3.23.16, you can restrict replication to a set of databases with replicate-do-db directives in `my.cnf' or just exclude a set of databases with replicate-ignore-db. --------------------------------------------------------------
