Re: Can the mysql replication limited to one database
Quoting Brown, Charles cbr...@bmi.com: Can the mysql replication limited to selected schema or database? Hi, yes it can. On the master side you control what is written to the binlog with my.cnf entries for each DB like: binlog-do-db=DB1 binlog-do-db=DB2 And on the slave side you use entries like: replicate-do-db=DB1 replicate-do-db=DB2 thanks Andy. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql
RE: Can the mysql replication limited to one database
Yes, doable. In my.cnf on master: Binlog-do-database = dbname1 Binlog-do-database = dbname2 Would replicate those two dbs only. There are many other combinations using binlog/replicate-do/ignore-db/table/wild. See the manual on replication, and especially the flowchart on how those interact (sometimes in unexpected ways). -Original Message- From: Brown, Charles [mailto:cbr...@bmi.com] Sent: Wednesday, May 02, 2012 8:44 AM To: Rick James Cc: mysql@lists.mysql.com Subject: Can the mysql replication limited to one database Hi Gurus, Can the mysql replication limited to selected schema or database?

Re: Can the mysql replication limited to one database
I recommend to use the 'wild' modifier, if you have a default db and you specify the schema in the query like update schemanotreplicated.mytable. you will miss that.

RE: Can the mysql replication limited to one database
Nothing in the slave's my.cnf. On the Master, binlog-do/ignore-* filters before leaving the Master. On the Slave, replicate-do/ignore-* (if used) would filter after getting to the Slave. That is, you _could_ do the replicate-* instead of the binlog-*, but that would be inefficient. Doing both is redundant. -Original Message- From: Brown, Charles [mailto:cbr...@bmi.com] Sent: Wednesday, May 02, 2012 11:15 AM To: Rick James Cc: mysql@lists.mysql.com Subject: RE: Can the mysql replication limited to one database Hello Rick, What goes into your my.cnf slave ?

RE: Can the mysql replication limited to one database
Doing both is redundant. Doing binlog (on the Master) is more efficient because it eliminates sending the other dbs. -Original Message- From: a.sm...@ukgrid.net [mailto:a.sm...@ukgrid.net] Sent: Wednesday, May 02, 2012 8:50 AM To: mysql@lists.mysql.com Subject: Re: Can the mysql replication limited to one database Quoting Brown, Charles cbr...@bmi.com: Can the mysql replication limited to selected schema or database?

RE: Can the mysql replication limited to one database
Here's the use case that screws up a lot of people: USE db_that_is_not_replicated; INSERT INTO db_that_IS_replicate.tbl ...; Surprise! That INSERT is not replicated. Workaround: *wild will notice it. The other way around, the INSERT will be replicated, then hang replication because the table won't be on the Slave.
