–replicate-do-db=name
Tells the slave thread to restrict replication to the
specified database. To specify more than one database,
use the directive multiple times, once for each database.
Note that this will only work if you do not use
cross-database queries such as UPDATE some_db.some_table
SET foo=’bar’ while having selected a different or no
database. If you need cross database updates to work,
make sure you have 3.23.28 or later, and use
replicate-wild-do-table=db_name.%.
–replicate-do-table=name
Tells the slave thread to restrict replication to the
specified table. To specify more than one table, use the
directive multiple times, once for each table. This will
work for cross-database updates, in contrast to
replicate-do-db.
–replicate-wild-do-table=name
Tells the slave thread to restrict replication to the
tables that match the specified wildcard pattern. To
specify more than one table, use the directive multiple
times, once for each table. This will work for
cross-database updates. Example:
replicate-wild-do-table=foo%.bar% will replicate only
updates to tables in all databases that start with foo
and whose table names start with bar
–replicate-ignore-db=name
Tells the slave thread to not replicate to the specified
database. To specify more than one database to ignore,
use the directive multiple times, once for each database.
This option will not work if you use cross database
updates. If you need cross database updates to work, make
sure you have 3.23.28 or later, and use
replicate-wild-ignore-table=db_name.%.
–replicate-ignore-table=name
Tells the slave thread to not replicate to the specified
table. To specify more than one table to ignore, use the
directive multiple times, once for each table. This will
work for cross-datbase updates, in contrast to
replicate-ignore-db.
–replicate-wild-ignore-table=name
Tells the slave thread to not replicate to the tables
that match the given wildcard pattern. To specify more
than one table to ignore, use the directive multiple
times, once for each table. This will work for
cross-database updates. Example:
replicate-wild-ignore-table=foo%.bar% will not do updates
to tables in databases that start with foo and whose
table names start with bar.
–replicate-rewrite-db=name
Updates to a database with a different name than the
original. Example:
replicate-rewrite-db=master_db_name->slave_db_name
–replicate-same-server-id
In replication, if set to 1, do not skip events having
our server id. Default value is 0 (to break infinite
loops in circular replication). Can’t be set to 1 if
–log-slave-updates is used.
–report-host=name Hostname or IP of the slave to be reported to to the
master during slave registration. Will appear in the
output of SHOW SLAVE HOSTS. Leave unset if you do not
want the slave to register itself with the master. Note
that it is not sufficient for the master to simply read
the IP of the slave off the socket once the slave
connects. Due to NAT and other routing issues, that IP
may not be valid for connecting to the slave from the
master or other hosts.
–report-user=name Undocumented
–report-password=name
Undocumented
–report-port=# Port for connecting to slave reported to the master
during slave registration. Set it only if the slave is
listening on a non-default port or if you have a special
tunnel from the master or other clients to the slave. If
not sure, leave this option unset.

–relay-log-index=name
The location and name to use for the file that keeps a
list of the last relay logs

write privileges to the mysql.user table

for each new file.
