MySQL复制不更新奴隶

Question

Trying to set up replication master - slave.

Master my.cnf

[mysqld]
bind-address = 0.0.0.0
port = 3306
server-id = 1
log-bin = /var/lib/mysql/mysql-bin
replicate-do-db = Test

Slave my.cnf

[mysqld]
log_output              = "FILE"
general_log_file        = /var/log/mysql/mysql.log
general_log             = 1
log_bin                 = /var/log/mysql/mysql-bin.log
server-id = 2
relay-log = /var/lib/mysql/mysql-relay-bin
relay-log-index = /var/lib/mysql/mysql-relay-bin.index
replicate-do-db = Test

SHOW SLAVE STATUS shows

Slave_IO_Running: Yes
Slave_SQL_Running: Yes

In relay log i see query executed on master.
And Read_Master_Log_Pos also updates.
But in general_log_file appear only

130530 14:50:25   523 Query     BEGIN
                  523 Query     COMMIT /* implicit, from Xid_log_event */

And changes on master not executed on slave. What i have missed?

This could be due to the following option:

replicate-do-db = Test

The replicate-do-db option can be very tricky and can sometimes behave in a manner that appears illogical .

It will only replicate statements where the default ((that is, the one selected by USE) database is set. So in your example that would mean that this is replicated:

use Test ;

insert into myTable (column) values (value);

But this will not be replicated:

insert into Test.myTable (column) values (value);

Try using the replicate-wild-do-table option instead:

replicate-wild-do-table=Test.%

Hopefully you will get some joy.
