The following options may be given as the first argument:
|
|
--print-defaults Print the program argument list and exit
|
|
--no-defaults Don't read default options from any options file
|
|

|
|
|
|
--abort-slave-event-count=#
|
|
Option used by mysql-test for debugging and testing of
|
|
replication.
|
|
--allow-suspicious-udfs
|
|
Allows use of UDFs consisting of only one symbol xxx()
|
|
without corresponding xxx_init() or xxx_deinit(). That
|
|
also means that one can load any function from any
|
|
library, for example exit() from libc.so
|
|

|
|
will also set transaction isolation level 'serializable'.

|
|
Offset added to Auto-increment columns. Used when
|
|
auto-increment-increment != 1

|
--automatic-sp-privileges

|
Creating and dropping stored procedures alters ACLs
|
|
(Defaults to on; use --skip-automatic-sp-privileges to disable.)

|
|
have. This comes into play when the main MySQL thread
|
|
gets very many connection requests in a very short time

|
-b, --basedir=name Path to installation directory. All paths are usually
|
|
resolved relative to this
|
|
--big-tables Allow big result sets by saving all temporary sets on
|

--bind-address=name IP address to bind to.

--binlog-cache-size=#
|

statement-based binary logging except for those
|
|
statements where only row-based is correct: those which
|
|
involve user-defined functions (i.e. UDFs) or the UUID()
|
|
function; for those, row-based binary logging is
|
|
automatically used. If NDBCLUSTER is enabled and
|
|
binlog-format is MIXED, the format switches to row-based
|
|
and back implicitly per each query accessing an
|
|
NDBCLUSTER table

|
Each thread that does a sequential scan allocates a
|
|
buffer of this size for each table it scans. If you do
|
|
many sequential scans, you may want to increase this
|
|
value
|
|
--read-only Make all non-temporary tables read-only, with the
|
|
exception for replication (slave) threads and users with
|
|
the SUPER privilege
|
|
--read-rnd-buffer-size=#
|
|
When reading rows in sorted order after a sort, the rows
|
|
are read through this buffer to avoid a disk seeks. If
|
|
not set, then it's set to the value of record_buffer
|
|
--record-buffer=# Deprecated; use --read-buffer-size instead.
|
|

|
|
--relay-log-index=name
|
|

|
|
list of the last relay logs
|
|
--relay-log-info-file=name
|
|

|
|
the SQL replication thread is in the relay logs
|
|
--relay-log-purge if disabled - do not purge relay logs. if enabled - purge
|
|
them as soon as they are no more needed
|
|
(Defaults to on; use --skip-relay-log-purge to disable.)
|
|
--relay-log-recovery
|
|
Enables automatic relay log recovery right after the
|
|
database startup, which means that the IO Thread starts
|
|
re-fetching from the master right after the last
|
|
transaction processed
|
|
--relay-log-space-limit=#
|
|
Maximum space to use for all relay logs
|
|
--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-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-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.
|
|
--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-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.
|
|
--report-host=name Hostname or IP of the slave to be reported 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-password=name
|
|
The account password of the slave to be reported to the
|

|
|
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
|
|
--report-user=name The account user name of the slave to be reported to the
|
|
master during slave registration

|
|
--skip-locking Deprecated option, use --skip-external-locking instead.

--skip-symlink Don't allow symlinking of tables. Deprecated option. Use
|
|
--skip-symbolic-links instead.
|
|
--skip-thread-priority
|
|
Don't give threads different priorities. This option is
|
|
deprecated because it has no effect; the implied behavior
|
|
is already the default.

|
|
--slave-exec-mode=name

|
the slave
