  • 0

I’ve got a single table in a master DB that I would like to replicate to multiple databases on one slave server. Like this:

masterDB.tableA -> slaveDB1.tableA
masterDB.tableA -> slaveDB2.tableA

slaveDB1 and slaveDB2 are on the same slave server. Is this possible?

I can get slaveDB1’s replication working no problem, but it’s as it it’s ignoring the command in my.cnf for slaveDB2:

replicate-rewrite-db="masterDB->slaveDB1"
replicate-rewrite-db="masterDB->slaveDB2"

replicate-wild-do-table=slaveDB1.tableA%
replicate-wild-do-table=slaveDB2.tableA%

Am I missing something, or can this just not be done with replication?

    From the docs

    To specify multiple rewrites, use this option multiple times. The server uses the first one with a from_name value that matches.

    This suggests it won’t work as it will only take into account the first of your two replicate-rewrite-db options (which is the behaviour you’re seeing).
