Windows bug: new line disappears when it is exactly at the right offset.
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.
The following specify which files/extra groups are read (specified before remaining options):
--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=# Additionally read default groups with # appended as a suffix.
--allow-suspicious-udfs
Allows use of user-defined functions (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
--alter-algorithm[=name]
Unused. One of: DEFAULT, COPY, INPLACE, NOCOPY, INSTANT.
Deprecated, will be removed in a future release.
--analyze-max-length=#
Fields which length in bytes more than this are skipped
by ANALYZE TABLE PERSISTENT unless explicitly listed in
the FOR COLUMNS () clause
--analyze-sample-percentage=#
Percentage of rows from the table ANALYZE TABLE will
sample to collect table statistics. Set to 0 to let
MariaDB decide what percentage of rows to sample
-a, --ansi Use ANSI SQL syntax instead of MariaDB 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 MariaDB can
have. This comes into play when the main MariaDB thread
gets many connection requests in a very short time
(Automatically configured unless set explicitly)
-b, --basedir=name Path to installation directory. All paths are usually
resolved relative to this
--big-tables Old variable, which if set to 1, allows large result sets
by saving all temporary sets to disk, avoiding 'table
full' errors. No longer needed, as the server now handles
this automatically. Deprecated, will be removed in a
future release.
--bind-address=name IP address to bind to. Several addresses may be
specified, separated by a comma (,)
--binlog-alter-two-phase
When set, split ALTER at binary logging into 2
statements: START ALTER and COMMIT/ROLLBACK ALTER
--binlog-annotate-row-events
Tells the master to annotate RBR events with the
statement that caused these events
(Defaults to on; use --skip-binlog-annotate-row-events to disable.)
--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-expire-logs-seconds=#
If non-zero, binary logs will be purged after
binlog_expire_logs_seconds seconds; It and
expire_logs_days are linked, such that changes in one are
converted into the other. Possible purges happen at
startup and at binary log rotation
--binlog-file-cache-size=#
The size of file cache for the binary log
--binlog-format=name
The binary logging format the master will use: ROW for
row-based binary logging (safer), STATEMENT for
statement-based binary logging (smaller binary logs),
MIXED for statement-based binary logging when it's safe
with fall back to row-based otherwise
--binlog-gtid-index Enable the creation of a GTID index for every binlog
file, and the use of such index for speeding up GTID
lookup in the binlog
(Defaults to on; use --skip-binlog-gtid-index to disable.)
--binlog-gtid-index-page-size=#
Page size to use for the binlog GTID index
--binlog-gtid-index-span-min=#
Control sparseness of the binlog GTID index. If set to N,
at most one index record will be added for every N bytes
of binlog file written, to reduce the size of the index.
Normally does not need tuning
--binlog-ignore-db=name
Tells the master that updates to the given database
should not be logged to the binary log
--binlog-large-commit-threshold=#
Increases transaction concurrency for large transactions
(i.e. those with sizes larger than this value) by using
the large transaction's cache file as a new binary log,
and rotating the active binary log to the large
transaction's cache file at commit time. This avoids the
default commit logic that copies the transaction cache
data to the end of the active binary log file while
holding a lock that prevents other transactions from
binlogging
--binlog-legacy-event-pos
Fill in the end_log_pos field of _all_ events in the
binlog, even when doing so costs performance. Can be used
in case some old application needs it for backwards
compatibility. Setting this option can hurt binlog
scalability
--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. This variable is deprecated and will be
removed in a future release. Deprecated, will be removed
in a future release.
(Defaults to on; use --skip-binlog-optimize-thread-scheduling 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',
'FULL_NODUP', 'NOBLOB' or 'MINIMAL' formats. 'FULL',
means that all columns in the before and after image are
logged. 'FULL_NODUP', means that all columns are logged
in before image, but only changed columns or all columns
of inserted record are logged in after image, 'NOBLOB',
means that MariaDB 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
--binlog-row-metadata=name
Controls whether metadata is logged using FULL , MINIMAL
format and NO_LOG. FULL causes all metadata to be logged;
MINIMAL means that only metadata actually required by
slave is logged; NO_LOG NO metadata will be logged
--binlog-space-limit=#
Alias for max_binlog_total_size. Compatibility with
Percona server
--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
--block-encryption-mode=name
Default block encryption mode for AES_ENCRYPT() and
AES_DECRYPT() functions. One of: aes-128-ecb, aes-192-ecb,
aes-256-ecb, aes-128-cbc, aes-192-cbc, aes-256-cbc,
aes-128-ctr, aes-192-ctr, aes-256-ctr
--bootstrap Used by MariaDB installation scripts
--bulk-insert-buffer-size=#
Size of tree cache used in bulk insert optimization. Note
that this is a limit per thread
--character-set-client-handshake
Don't ignore client side character set value sent during
handshake
(Defaults to on; use --skip-character-set-client-handshake to disable.)
--character-set-collations=name
Overrides for character set default collations
--character-set-filesystem=name
Set the filesystem character set
-C, --character-set-server=name
Set the default character set
--character-sets-dir=name
Directory where character sets are
-r, --chroot=name Chroot mariadbd process during startup
--collation-server=name
Set the default collation
--column-compression-threshold=#
Minimum column data length eligible for compression
--column-compression-zlib-level=#
zlib compression level (1 gives best speed, 9 gives best
compression)
--column-compression-zlib-strategy=name
The strategy parameter is used to tune the compression
algorithm. Use the value DEFAULT_STRATEGY for normal
data, FILTERED for data produced by a filter (or
predictor), HUFFMAN_ONLY to force Huffman encoding only
(no string match), or RLE to limit match distances to one
(run-length encoding). Filtered data consists mostly of
small values with a somewhat random distribution. In this
case, the compression algorithm is tuned to compress them
better. The effect of FILTERED is to force more Huffman
coding and less string matching; it is somewhat
intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY.
RLE is designed to be almost as fast as HUFFMAN_ONLY, but
give better compression for PNG image data. The strategy
parameter only affects the compression ratio but not the
correctness of the compressed output even if it is not
set appropriately. FIXED prevents the use of dynamic
Huffman codes, allowing for a simpler decoder for special
applications
--column-compression-zlib-wrap
Generate zlib header and trailer and compute adler32
check value. It can be used with storage engines that
don't provide data integrity verification to detect data
corruption
--completion-type=name
The transaction completion type. One of: NO_CHAIN, CHAIN,
RELEASE
--concurrent-insert[=name]
Use concurrent insert with MyISAM. One of: NEVER, AUTO,
ALWAYS
--console Write error output on screen; don't remove the console
window on Windows
--core-file Write core on crashes
-h, --datadir=name Path to the database root directory
--deadlock-search-depth-long=#
Long search depth for the two-step deadlock detection
--deadlock-search-depth-short=#
Short search depth for the two-step deadlock detection
--deadlock-timeout-long=#
Long timeout for the two-step deadlock detection (in
microseconds)
--deadlock-timeout-short=#
Short timeout for the two-step deadlock detection (in
microseconds)
--default-password-lifetime=#
This defines the global password expiration policy. 0
means automatic password expiration is disabled. If the
value is a positive integer N, the passwords must be
changed every N days. This behavior can be overridden
using the password expiration options in ALTER USER
--default-regex-flags=name
Default flags for the regex library. Any combination of:
DOTALL, DUPNAMES, EXTENDED, EXTENDED_MORE, EXTRA,
MULTILINE, UNGREEDY, or ALL to set all combinations

The default storage engine for new tables
--default-time-zone=name
Set the default time zone
--default-tmp-storage-engine=name
The default storage engine for user-created temporary
tables
--default-week-format=#
The default week format used by WEEK() functions
--delay-key-write[=name]
Specifies how MyISAM tables handles CREATE TABLE
DELAY_KEY_WRITE. If set to ON, the default, any DELAY KEY
WRITEs are honored. The key buffer is then flushed only
when the table closes, speeding up writes. MyISAM tables
should be automatically checked upon startup in this
case, and --external locking should not be used, as it
can lead to index corruption. If set to OFF, DELAY KEY
WRITEs are ignored, while if set to ALL, all new opened
tables are treated as if created with DELAY KEY WRITEs
enabled
--delayed-insert-limit=#
After inserting delayed_insert_limit rows, the INSERT
DELAYED handler will check if there are any SELECT
statements pending. If so, it allows these to execute
before continuing
--delayed-insert-timeout=#
How long a INSERT DELAYED thread should wait for INSERT
statements before terminating
--delayed-queue-size=#
What size queue (in rows) should be allocated for
handling INSERT DELAYED. If the queue becomes full, any
client that does INSERT DELAYED will wait until there is
room in the queue again
--disconnect-on-expired-password
This variable controls how the server handles clients
that are not aware of the sandbox mode. If enabled, the
server disconnects the client, otherwise the server puts
the client in a sandbox mode
--div-precision-increment=#
Precision of the result of '/' operator will be increased
on that value
--encrypt-binlog Encrypt binary logs (including relay logs)
--encrypt-tmp-disk-tables
Encrypt temporary on-disk tables (created as part of
query execution)
--encrypt-tmp-files Encrypt temporary files (created for filesort, binary log
cache, etc)
--enforce-storage-engine=name
Force the use of a storage engine for new tables
--eq-range-index-dive-limit=#
The optimizer will use existing index statistics instead
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
--event-scheduler[=name]
Enable the event scheduler. Possible values are ON, OFF,
and DISABLED (keep the event scheduler completely
deactivated, it cannot be activated run-time)
--expensive-subquery-limit=#
The maximum number of rows a subquery may examine in
order to be executed during optimization and used for
constant optimization
--expire-logs-days=#
If non-zero, binary logs will be purged after
expire_logs_days days; It and binlog_expire_logs_seconds
are linked, such that changes in one are converted into
the other, presentable as a decimal value with 1/1000000
of the day precision; possible purges happen at startup
and at binary log rotation
--explicit-defaults-for-timestamp
This option causes CREATE TABLE to create all TIMESTAMP
columns as NULL with DEFAULT NULL attribute, Without this
option, TIMESTAMP columns are NOT NULL and have implicit
DEFAULT clauses
(Defaults to on; use --skip-explicit-defaults-for-timestamp to disable.)
--external-locking Use system (external) locking (disabled by default).
With this option enabled you can run myisamchk to test
(not repair) tables while the MariaDB server is running.
Disable with --skip-external-locking
--extra-max-connections=#
The number of connections on extra-port
--extra-port=# Extra port number to use for tcp connections in a
one-thread-per-connection manner. 0 means don't use
another port
--flashback Setup the server to use flashback. This enables binary
log in row mode and will enable extra logging for DDL's
needed by flashback feature
--flush Flush MyISAM tables to disk between SQL commands
--flush-time=# A dedicated thread is created to flush all tables at the
given interval
--ft-boolean-syntax=name
List of operators for MATCH ... AGAINST ( ... IN BOOLEAN
MODE)
--ft-max-word-len=# The maximum length of the word to be included in a
FULLTEXT index. Note: FULLTEXT indexes must be rebuilt
after changing this variable
--ft-min-word-len=# The minimum length of the word to be included in a
FULLTEXT index. Note: FULLTEXT indexes must be rebuilt
after changing this variable
--ft-query-expansion-limit=#
Number of best matches to use for query expansion
--ft-stopword-file=name
Use stopwords from this file instead of built-in list
--gdb Set up signals usable for debugging. Deprecated, will be
--general-log Log connections and queries to a table or log file.
Defaults logging to a file 'hostname'.log or a table
mysql.general_log if --log-output=TABLE is used
--general-log-file=name
Log connections and queries to given file
--getopt-prefix-matching
Recognize command-line options by their unambiguous
prefixes
(Defaults to on; use --skip-getopt-prefix-matching to disable.)
--group-concat-max-len=#
The maximum length of the result of function
GROUP_CONCAT()
--gtid-cleanup-batch-size=#
Normally does not need tuning. How many old rows must
accumulate in the mysql.gtid_slave_pos table before a
background job will be run to delete them. Can be
increased to reduce number of commits if using many
different engines with --gtid_pos_auto_engines, or to
reduce CPU overhead if using a huge number of different
gtid_domain_ids. Can be decreased to reduce number of old
rows in the table
--gtid-domain-id=# Used with global transaction ID to identify logically
independent replication streams. When events can
propagate through multiple parallel paths (for example
multiple masters), each independent source server must
use a distinct domain_id. For simple tree-shaped
replication topologies, it can be left at its default, 0
--gtid-ignore-duplicates
When set, different master connections in multi-source
replication are allowed to receive and process event
groups with the same GTID (when using GTID mode). Only
one will be applied, any others will be ignored. Within a
given replication domain, just the sequence number will
be used to decide whether a given GTID has been already
applied; this means it is the responsibility of the user
to ensure that GTID sequence numbers are strictly
increasing
--gtid-pos-auto-engines=name
List of engines for which to automatically create a
mysql.gtid_slave_pos_ENGINE table, if a transaction using
that engine is replicated. This can be used to avoid
introducing cross-engine transactions, if engines are
used different from that used by table
mysql.gtid_slave_pos
--gtid-strict-mode Enforce strict seq_no ordering of events in the binary
log. Slave stops with an error if it encounters an event
that would cause it to generate an out-of-order binlog if
executed. When ON the same server-id semisync-replicated
transactions that duplicate existing ones in binlog are
ignored without error and slave interruption
-?, --help Display this help and exit
--histogram-size=# Number of bytes used for a histogram. If set to 0, no
histograms are created by ANALYZE
--histogram-type=name
Specifies type of the histograms created by ANALYZE.
Possible values are: SINGLE_PREC_HB - single precision
height-balanced, DOUBLE_PREC_HB - double precision
height-balanced, JSON_HB - height-balanced, stored as
JSON

(Automatically configured unless set explicitly)
--idle-readonly-transaction-timeout=#
The number of seconds the server waits for read-only idle
transaction
--idle-transaction-timeout=#
The number of seconds the server waits for idle
transaction

The number of seconds the server waits for write idle
transaction
--ignore-builtin-innodb
Disable initialization of builtin InnoDB plugin
--ignore-db-dirs=name
Specifies a directory to add to the ignore list when
collecting database names from the datadir. Put a blank
argument to reset the list accumulated so far
--in-predicate-conversion-threshold=#
The minimum number of scalar elements in the value list
of IN predicate that triggers its conversion to IN
subquery. Set to 0 to disable the conversion
--init-connect=name Command(s) that are executed for each new connection
(unless the user has SUPER privilege)
--init-file=name Read SQL commands from this file at startup
--init-rpl-role=name
Set the replication role. One of: MASTER, SLAVE
--init-slave=name Command(s) that are executed by a slave server each time
the SQL thread starts
--interactive-timeout=#
The number of seconds the server waits for activity on an
interactive connection before closing it
--join-buffer-size=#
The size of the buffer that is used for joins
--join-buffer-space-limit=#
The limit of the space for all join buffers used by a
query
--join-cache-level=#
Controls what join operations can be executed with join
buffers. Odd numbers are used for plain join buffers
while even numbers are used for linked buffers
--keep-files-on-create
Don't overwrite stale .MYD and .MYI even if no directory
is specified. Deprecated, will be removed in a future
release.
--key-buffer-size=# The size of the buffer used for index blocks for MyISAM
tables. Increase this to get faster index handling
--key-cache-age-threshold=#
This characterizes the number of hits a hot block has to
be untouched until it is considered aged enough to be
downgraded to a warm block. This specifies the percentage
ratio of that number of hits to the total number of
blocks in key cache
--key-cache-block-size=#
The default size of key cache blocks
--key-cache-division-limit=#
The minimum percentage of warm blocks in key cache
--key-cache-file-hash-size=#
Number of hash buckets for open and changed files. If
you have a lot of MyISAM files open you should increase
this for faster flush of changes. A good value is
probably 1/10 of number of possible open MyISAM files
--key-cache-segments=#
The number of segments in a key cache
-L, --language=name Client error messages in given language. May be given as
a full path. Deprecated, will be removed in a future
release. Please use --lc-messages-dir instead.
--large-pages Enable support for large pages
--lc-messages=name Set the language used for the error messages
-L, --lc-messages-dir=name
Directory where error messages are
--lc-time-names=name
Set the language used for the month names and the days of
the week
--local-infile Enable LOAD DATA LOCAL INFILE
(Defaults to on; use --skip-local-infile to disable.)
--lock-wait-timeout=#
Timeout in seconds to wait for a lock before returning an
error
--log-basename=name Basename for all log files and the .pid file. This sets
all log file names at once (in 'datadir') and is normally
the only option you need for specifying log files. Sets
names for --log-bin, --log-bin-index, --relay-log,
--relay-log-index, --general-log-file,
--log-slow-query-file, --log-error-file, and --pid-file
--log-bin[=name] Log update queries in binary format. Optional argument
should be name for binary log. If not given
'datadir'/'log-basename'-bin or 'datadir'/mysql-bin will
be used (the later if --log-basename is not specified).
We strongly recommend to use either --log-basename or
specify a filename to ensure that replication doesn't
stop if the real hostname of the computer changes
--log-bin-compress Whether the binary log can be compressed
--log-bin-compress-min-len[=#]
Minimum length of sql statement (in statement mode) or
record (in row mode) that can be compressed
--log-bin-index=name
File that holds the names for last binary log files
--log-bin-trust-function-creators
If set to FALSE (the default), then when --log-bin is
used, creation of a stored function (or trigger) is
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-ddl-recovery=name
Path to file used for recovery of DDL statements after a
crash
--log-disabled-statements=name

directive multiple times, once for each table. This will
work for cross-database updates, in contrast to
replicate-do-db
--replicate-events-marked-for-skip=name
Whether the slave should replicate events that were
created with @@skip_replication=1 on the master. Default
REPLICATE (no events are skipped). Other values are
FILTER_ON_SLAVE (events will be sent by the master but
ignored by the slave) and FILTER_ON_MASTER (events marked
with @@skip_replication=1 will be filtered on the master
and never be sent to the slave)
--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-database 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
master during slave registration
--report-port=# Port for connecting to slave reported to the master
during slave registration. Set it only if the slave is

idempotent. This means that CREATE TABLE is treated as
CREATE TABLE OR REPLACE and DROP TABLE is treated as DROP
TABLE IF EXISTS
--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
domain from grabbing all threads and thus stalling other
domains. The default of 0 means to allow a domain to grab
as many threads as it wants, up to the value of
slave_parallel_threads
--slave-exec-mode=name
How replication events should be executed. Legal values
are STRICT (default) and IDEMPOTENT. In IDEMPOTENT mode,

parallel, and handles any conflicts with rollback and
retry. "conservative" limits parallelism in an effort to
avoid any conflicts. "aggressive" tries to maximise the
parallelism, possibly at the cost of increased conflict
rate. "minimal" only parallelizes the commit steps of
transactions. "none" disables parallel apply completely
--slave-parallel-threads=#
If non-zero, number of threads to spawn to apply in
parallel events on the slave that were group-committed on
the master or were logged with GTID in different
replication domains. Note that these threads are in
addition to the IO and SQL threads, which are always
created by a replication slave
--slave-parallel-workers=#
Alias for slave_parallel_threads
--slave-run-triggers-for-rbr=name
Modes for how triggers in row-base replication on slave
side will be executed. Legal values are NO (default),
YES, LOGGING and ENFORCE. NO means that trigger for RBR
will not be running on slave. YES and LOGGING means that
triggers will be running on slave, if there was not
triggers running on the master for the statement. LOGGING
