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 option file.
|
|
--defaults-file=# Only read default options from the given file #.
|
|
--defaults-extra-file=# Read this file after the global files are read.
|
|
|
|
--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
|
|
-a, --ansi Use ANSI SQL syntax instead of MySQL syntax. This mode
|
|
will also set transaction isolation level 'serializable'.
|
|
--auto-increment-increment[=#]
|
|
Auto-increment columns are incremented by this
|
|
--auto-increment-offset[=#]
|
|
Offset added to Auto-increment columns. Used when
|
|
auto-increment-increment != 1
|
|
--autocommit Set default value for autocommit (0 or 1)
|
|
(Defaults to on; use --skip-autocommit to disable.)
|
|
--automatic-sp-privileges
|
|
Creating and dropping stored procedures alters ACLs
|
|
(Defaults to on; use --skip-automatic-sp-privileges to disable.)
|
|
--back-log=# The number of outstanding connection requests MySQL can
|
|
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
|
|
file (Solves most 'table full' errors)
|
|
--bind-address=name IP address to bind to.
|
|
--binlog-annotate-row-events
|
|
Tells the master to annotate RBR events with the
|
|
statement that caused these events
|
|
--binlog-cache-size=#
|
|
The size of the transactional cache for updates to
|
|
transactional engines for the binary log. If you often
|
|
use transactions containing many statements, you can
|
|
increase this to get more performance
|
|
--binlog-checksum=name
|
|
Type of BINLOG_CHECKSUM_ALG. Include checksum for log
|
|
events in the binary log. One of: NONE, CRC32
|
|
--binlog-commit-wait-count=#
|
|
If non-zero, binlog write will wait at most
|
|
binlog_commit_wait_usec microseconds for at least this
|
|
many commits to queue up for group commit to the binlog.
|
|
This can reduce I/O on the binlog and provide increased
|
|
opportunity for parallel apply on the slave, but too high
|
|
a value will decrease commit throughput.
|
|
--binlog-commit-wait-usec=#
|
|
Maximum time, in microseconds, to wait for more commits
|
|
to queue up for binlog group commit. Only takes effect if
|
|
the value of binlog_commit_wait_count is non-zero.
|
|
--binlog-direct-non-transactional-updates
|
|
Causes updates to non-transactional engines using
|
|
statement format to be written directly to binary log.
|
|
Before using this option make sure that there are no
|
|
dependencies between transactional and non-transactional
|
|
tables such as in the statement INSERT INTO t_myisam
|
|
SELECT * FROM t_innodb; otherwise, slaves may diverge
|
|
from the master.
|
|
--binlog-do-db=name Tells the master it should log updates for the specified
|
|
database, and exclude all others not explicitly
|
|
mentioned.
|
|
--binlog-format=name
|
|
What form of binary logging the master will use: either
|
|
ROW for row-based binary logging, STATEMENT for
|
|
statement-based binary logging, or MIXED. MIXED is
|
|
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.
|
|
--binlog-ignore-db=name
|
|
Tells the master that updates to the given database
|
|
should not be logged to the binary log.
|
|
--binlog-optimize-thread-scheduling
|
|
Run fast part of group commit in a single thread, to
|
|
optimize kernel thread scheduling. On by default. Disable
|
|
to run each transaction in group commit in its own
|
|
thread, which can be slower at very high concurrency.
|
|
This option is mostly for testing one algorithm versus
|
|
the other, and it should not normally be necessary to
|
|
change it.

|
(Defaults to on; use --skip-binlog-optimize-thread-scheduling to disable.)
|
|
--binlog-row-event-max-size=#
|

--binlog-stmt-cache-size=#
|
|

|
allowed only to users having the SUPER privilege and only
|
|
if this stored function (trigger) may not break binary
|
|
logging. Note that if ALL connections to this server
|
|
ALWAYS use row-based binary logging, the security issues
|
|
do not exist and the binary logging cannot break, so you
|
|
can safely set this to TRUE
|
|
--log-error[=name] Log errors to file (instead of stdout). If file name is
|
|
not specified then 'datadir'/'log-basename'.err or the

|
|
result in better query plans, but take longer to compile
|
|
a query. Values smaller than the number of tables in a
|
|
relation result in faster optimization, but may produce
|
|
very bad query plans. If set to 0, the system will
|
|
automatically pick a reasonable value; if set to 63, the

--optimizer-use-condition-selectivity=#
|
|
Controls selectivity of which conditions the optimizer
|
|
takes into account to calculate cardinality of a partial
|
|
join when it searches for the best execution plan
|
|
Meaning: 1 - use selectivity of index backed range
|
|
conditions to calculate the cardinality of a partial join
|
|
if the last joined table is accessed by full table scan
|
|
or an index scan, 2 - use selectivity of index backed
|
|
range conditions to calculate the cardinality of a
|
|
partial join in any case, 3 - additionally always use
|
|
selectivity of range conditions that are not backed by
|
|
any index to calculate the cardinality of a partial join,
|
|
4 - use histograms to calculate selectivity of range
|
|
conditions that are not backed by any index to calculate
|
|
the cardinality of a partial join.5 - additionally use
|
|
selectivity of certain non-range predicates calculated on
|
|
record samples

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

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

|
--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.

|
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
|

How replication events should be executed. Legal values
|
|
are STRICT and IDEMPOTENT (default). In IDEMPOTENT mode,
|

|
--slave-domain-parallel-threads=#
|
|
Maximum number of parallel threads to use on slave for
|
|
events in a single replication domain. When using
|
|
multiple domains, this can be used to limit a single
