mysqld命令参数详解
mysqld Ver 5.7. for Win64 on x86_64 (MySQL Community Server (GPL))
Copyright (c) , , Oracle and/or its affiliates. All rights reserved. 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 [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 F:\temp\\mysql-5.7.-winx64\mysql-5.7.-winx64\my.ini F:\temp\\mysql-5.7.-winx64\mysql-5.7.-winx64\my.cnf
The following groups are read: mysqld server mysqld-5.7
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 !=
--autocommit Set default value for autocommit ( or )
(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. 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-group-commit-sync-delay=#
The number of microseconds the server waits for the
binary log group commit sync queue to fill before
continuing. Default: . Min: . Max: .
--binlog-group-commit-sync-no-delay-count=#
If there are this many transactions in the commit sync
queue and the server is waiting for more transactions to
be enqueued (as set using
--binlog-group-commit-sync-delay), the commit procedure
resumes.
--binlog-gtid-simple-recovery
If this option is enabled, the server does not open more
than two binary logs when initializing GTID_PURGED and
GTID_EXECUTED, either during server restart or when
binary logs are being purged. Enabling this option is
useful when the server has already generated many binary
logs without GTID events (e.g., having GTID_MODE = OFF).
Note: If this option is enabled, GLOBAL.GTID_EXECUTED and
GLOBAL.GTID_PURGED may be initialized wrongly in two
cases: () All binary logs were generated by MySQL 5.7.
or older, and GTID_MODE was ON for some binary logs but
OFF for the newest binary log. () The oldest existing
binary log was generated by MySQL 5.7. or older, and SET
GTID_PURGED was issued after the oldest binary log was
generated. If a wrong set is computed in one of case ()
or case (), it will remain wrong even if the server is
later restarted with this option disabled.
(Defaults to on; use --skip-binlog-gtid-simple-recovery to disable.)
--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=#

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 .
--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
--blackhole[=name] Enable or disable BLACKHOLE plugin. Possible values are
ON, OFF, FORCE (don't start if the plugin fails to load).
--block-encryption-mode=name
mode for AES_ENCRYPT/AES_DECRYPT

trace), if variable is set to , repeats the structure's
key (if it has one) near the closing bracket
--enforce-gtid-consistency[=name]
Prevents execution of statements that would be impossible
to log in a transactionally safe manner. Currently, the
disallowed statements include CREATE TEMPORARY TABLE
inside transactions, all updates to non-transactional
tables, and CREATE TABLE ... SELECT.
--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

special case, if variable is , the thread never wakes up
to compress the gtid_executed table.
--gtid-mode=name Controls whether Global Transaction Identifiers (GTIDs)
are enabled. Can be OFF, OFF_PERMISSIVE, ON_PERMISSIVE,
or ON. OFF means that no transaction has a GTID.

assigned any GTID, and replicated transactions are
allowed to have or not have a GTID. ON_PERMISSIVE means
that new transactions are assigned a GTID, and replicated
transactions are allowed to have or not have a GTID. ON
means that all transactions have a GTID. ON is required
on a master before any slave can use
MASTER_AUTO_POSITION=. To safely switch from OFF to ON,
first set all servers to OFF_PERMISSIVE, then set all

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

them as soon as they are no more needed
(Defaults to on; use --skip-relay-log-purge to disable.)
--relay-log-recovery

database startup, which means that the IO Thread starts
re-fetching from the master right after the last
transaction processed
--relay-log-space-limit=#

--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. 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. 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 , do not skip events having
our server id. Default value is (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.

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

snapshot - but not any work done / data modified within
the transaction).
--sha256-password-proxy-users
If set to FALSE (the default), then the sha256_password
authentication plugin will not signal for authenticated

mysql命令参数详解
mysql Ver 14.14 Distrib 5.7., for Win64 (x86_64)
Copyright (c) , , Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners. Usage: mysql [OPTIONS] [database]
-?, --help Display this help and exit.
-I, --help Synonym for -?
--auto-rehash Enable automatic rehashing. One doesn't need to use
'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
(Defaults to on; use --skip-auto-rehash to disable.)
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect.
--auto-vertical-output
Automatically switch to vertical output mode if the
result is wider than the terminal width.
-B, --batch Don't use history file. Disable interactive behavior.
(Enables --silent.)
--bind-address=name IP address to bind to.
--character-sets-dir=name
Directory for character set files.
--column-type-info Display column type information.
-c, --comments Preserve comments. Send comments to the server. The
default is --skip-comments (discard comments), enable
with --comments.
-C, --compress Use compression in server/client protocol.
-#, --debug[=#] This is a non-debug version. Catch this and exit.
--debug-check This is a non-debug version. Catch this and exit.
-T, --debug-info This is a non-debug version. Catch this and exit.
-D, --database=name Database to use.
--default-character-set=name
Set the default character set.
--delimiter=name Delimiter to be used.
--enable-cleartext-plugin
Enable/disable the clear text authentication plugin.
-e, --execute=name Execute command and quit. (Disables --force and history
file.)
-E, --vertical Print the output of a query (rows) vertically.
-f, --force Continue even if we get an SQL error.
--histignore=name A colon-separated list of patterns to keep statements
from getting logged into syslog and mysql history.
-G, --named-commands
Enable named commands. Named commands mean this program's
internal commands; see mysql> help . When enabled, the
named commands can be used from any line of the query,
otherwise only from the first line, before an enter.
Disable with --disable-named-commands. This option is
disabled by default.
-i, --ignore-spaces Ignore space after function names.
--init-command=name SQL Command to execute when connecting to MySQL server.
Will automatically be re-executed when reconnecting.
--local-infile Enable/disable LOAD DATA LOCAL INFILE.
-b, --no-beep Turn off beep on error.
-h, --host=name Connect to host.
-H, --html Produce HTML output.
-X, --xml Produce XML output.
--line-numbers Write line numbers for errors.
(Defaults to on; use --skip-line-numbers to disable.)
-L, --skip-line-numbers
Don't write line number for errors.
-n, --unbuffered Flush buffer after each query.
--column-names Write column names in results.
(Defaults to on; use --skip-column-names to disable.)
-N, --skip-column-names
Don't write column names in results.
--sigint-ignore Ignore SIGINT (CTRL-C).
-o, --one-database Ignore statements except those that occur while the
default database is the one named at the command line.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's asked from the tty.
-W, --pipe Use named pipes to connect to server.
-P, --port=# Port number to use for connection or for default to, in
order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/services, built-in default ().
--prompt=name Set the mysql prompt to this value.
--protocol=name The protocol to use for connection (tcp, socket, pipe,
memory).
-q, --quick Don't cache result, print it row by row. This may slow
down the server if the output is suspended. Doesn't use
history file.
-r, --raw Write fields without conversion. Used with --batch.
--reconnect Reconnect if the connection is lost. Disable with
--disable-reconnect. This option is enabled by default.
(Defaults to on; use --skip-reconnect to disable.)
-s, --silent Be more silent. Print results with a tab as separator,
each row on new line.
--shared-memory-base-name=name
Base name of shared memory.
-S, --socket=name The socket file to use for connection.
--ssl-mode=name SSL connection mode.
--ssl Deprecated. Use --ssl-mode instead.
(Defaults to on; use --skip-ssl to disable.)
--ssl-verify-server-cert
Deprecated. Use --ssl-mode=VERIFY_IDENTITY instead.
--ssl-ca=name CA file in PEM format.
--ssl-capath=name CA directory.
--ssl-cert=name X509 cert in PEM format.
--ssl-cipher=name SSL cipher to use.
--ssl-key=name X509 key in PEM format.
--ssl-crl=name Certificate revocation list.
--ssl-crlpath=name Certificate revocation list path.
--tls-version=name TLS version to use, permitted values are: TLSv1, TLSv1.
-t, --table Output in table format.
--tee=name Append everything into outfile. See interactive help (\h)
also. Does not work in batch mode. Disable with
--disable-tee. This option is disabled by default.
-u, --user=name User for login if not current user.
-U, --safe-updates Only allow UPDATE and DELETE that uses keys.
-U, --i-am-a-dummy Synonym for option --safe-updates, -U.
-v, --verbose Write more. (-v -v -v gives the table output format).
-V, --version Output version information and exit.
-w, --wait Wait and retry if connection is down.
--connect-timeout=# Number of seconds before connection timeout.
--max-allowed-packet=#
The maximum packet length to send to or receive from
server.
--net-buffer-length=#
The buffer size for TCP/IP and socket communication.
--select-limit=# Automatic limit for SELECT when using --safe-updates.
--max-join-size=# Automatic limit for rows in a join when using
--safe-updates.
--secure-auth Refuse client connecting to server if it uses old
(pre-4.1.) protocol. Deprecated. Always TRUE
--server-arg=name Send embedded server this as a parameter.
--show-warnings Show warnings after every statement.
-j, --syslog Log filtered interactive commands to syslog. Filtering of
commands depends on the patterns supplied via histignore
option besides the default patterns.
--plugin-dir=name Directory for client-side plugins.
--default-auth=name Default authentication client-side plugin to use.
--binary-mode By default, ASCII '\0' is disallowed and '\r\n' is
translated to '\n'. This switch turns off both features,
and also turns off parsing of all clientcommands except
\C and DELIMITER, in non-interactive mode (for input
piped to mysql or loaded using the 'source' command).
This is necessary when processing output from mysqlbinlog
that may contain blobs.
--connect-expired-password
Notify the server that this client is prepared to handle
expired password sandbox mode. 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 D:\mysql-5.7.-winx64\my.ini D:\mysql-5.7.-winx64\my.cnf
The following groups are read: mysql client
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. Variables (--variable-name=value)
and boolean options {FALSE|TRUE} Value (after reading options)
