mysqld.exe Ver 5.6.24 for Win32 on x86 (MySQL Community Server (GPL))

Oracle is a registered trademark of Oracle Corporation and/or its

affiliates. Other names may be trademarks of their respective

owners.

Starts the MySQL database server.

Usage: mysqld.exe [OPTIONS]

NT and Win32 specific options:

--install Install the default service (NT).

--install-manual Install the default service started manually (NT).

--install service_name Install an optional service (NT).

--install-manual service_name Install an optional service started manually (NT).

--remove Remove the default service from the service list (NT).

--remove service_name Remove the service_name from the service list (NT).

--enable-named-pipe Only to be used for the default server (NT).

--standalone Dummy option to start as a standalone server (NT).

Default options are read from the following files in the given order:

C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\my.ini C:\my.cnf C:\Program Files\MySQL\MySQL Server 5.6\my.ini C:\Program Files\MySQL\MySQL Server 5.6\my.cnf

The following groups are read: mysqld server mysqld-5.6

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,

except for login file.

--defaults-file=# Only read default options from the given file #.

--defaults-extra-file=# Read this file after the global files are read.

--defaults-group-suffix=#

Also read groups with concat(group, suffix)

--login-path=# Read this path from the login 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

-a, --ansi Use ANSI SQL syntax instead of MySQL syntax. This mode

will also set transaction isolation level 'serializable'.

--archive[=name] Enable or disable ARCHIVE plugin. Possible values are ON,

OFF, FORCE (don't start if the plugin fails to load).

--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.)

--avoid-temporal-upgrade

When this option is enabled, the pre-5.6.4 temporal types

are not upgraded to the new format for ALTER TABLE

requests ADD/CHANGE/MODIFY COLUMN, ADD INDEX or FORCE

operation. This variable is deprecated and will be

removed in a future release.

--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-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. Possible values are NONE and

CRC32; default is CRC32.

--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-error-action=name

When statements cannot be written to the binary log due

to a fatal error, the server can either ignore the error

and let the master continue, or abort.

--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. 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

--binlog-gtid-simple-recovery

If this option is enabled, the server does not scan more

than one binary log for every iteration when initializing

GTID sets on server restart. Enabling this option is very

useful when restarting a server which has already

generated lots of binary logs without GTID events. Note:

If this option is enabled, GLOBAL.GTID_EXECUTED and

GLOBAL.GTID_PURGED cannot be initialized correctly if

binary log(s) with GTID events were generated before

binary log(s) without GTID events, for example if

gtid_mode is disabled when the server has already

generated binary log(s) with GTID events and not purged

them.

--binlog-ignore-db=name

Tells the master that updates to the given database

should not be logged to the binary log.

--binlog-max-flush-queue-time=#

The maximum time that the binary log group commit will

keep reading transactions before it flush the

transactions to the binary log (and optionally sync,

depending on the value of sync_binlog).

--binlog-order-commits

Issue internal commit calls in the same order as

transactions are written to the binary log. Default is to

order commits.

(Defaults to on; use --skip-binlog-order-commits to disable.)

--binlog-row-event-max-size=#

The maximum size of a row-based binary log event in

bytes. Rows will be grouped into events smaller than this

size if possible. The value has to be a multiple of 256.

--binlog-row-image=name

Controls whether rows should be logged in 'FULL',

'NOBLOB' or 'MINIMAL' formats. 'FULL', means that all

columns in the before and after image are logged.

'NOBLOB', means that mysqld avoids logging blob columns

whenever possible (eg, blob column was not changed or is

not part of primary key). 'MINIMAL', means that a PK

equivalent (PK columns or full row if there is no PK in

the table) is logged in the before image, and only

changed columns are logged in the after image. (Default:

FULL).

--binlog-rows-query-log-events

Allow writing of Rows_query_log events into binary log.

--binlog-stmt-cache-size=#

The size of the statement cache for updates to

non-transactional engines for the binary log. If you

often use statements updating a great number of rows, you

can increase this to get more performance

--binlogging-impossible-mode=name

On a fatal error when statements cannot be binlogged the

behaviour can be ignore the error and let the master

continue or abort the server. This variable is deprecated

and will be removed in a future release. Please use

binlog_error_action instead.

--blackhole[=name] Enable or disable BLACKHOLE plugin. Possible values are

ON, OFF, FORCE (don't start if the plugin fails to load).

statements pending. If so, it allows these to execute

before continuing. This variable is deprecated along with

INSERT DELAYED.

--delayed-insert-timeout=#

How long a INSERT DELAYED thread should wait for INSERT

statements before terminating.This variable is deprecated

along with INSERT DELAYED.

--delayed-queue-size=#

tables, and CREATE TABLE ... SELECT.

--eq-range-index-dive-limit=#

of doing index dives for equality ranges if the number of

equality ranges for the index is larger than or equal to

this number. If set to 0, index dives are always used.

columns as NULL with DEFAULT NULL attribute, Without this

option, TIMESTAMP columns are NOT NULL and have implicit

DEFAULT clauses. The old behavior is deprecated.

updates to tables in all databases that start with foo

and whose table names start with bar.

ALL_UNSIGNED to treat all integer column type data to be

unsigned values, and ALL_SIGNED to treat all integer

column type data to be signed values. Default treatment
