After using the binlog_ignore_db parameter on MySQL master, all statements executed by mysq-e do not write binlog.

Looking at the MySQL operation manual, ignoring the copy of a library has two parameters:

1 、 binlog_ignore_db

If this parameter is set to master, such as binlog_ignore_db=test, then all operations (add, delete, change) against the library will not be recorded, so that the number of binlog accepted by slave will be reduced, and the network I will be reduced.

2 、 replicate_ignore_db

If this parameter is set on slave, such as replicate_ignore_db=test, then all operations (add, delete, change) under the library will not be performed by the SQL thread, so that although the performance of slave O has not been improved, it ensures the security of slave data.

If the binlog_ignore_db=test parameter is used in master, the executed SQL must use the use command, otherwise the data cannot be synchronized

Suggestion: if you want to ignore a library on slave, use replicate_ignore_db instead of binlog_ignore_db.
