Starts the MySQL database server.

Usage: C:\\Program Files\\MySQL\\MySQL Server 5.7\\bin\\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 5.7\\my.ini C:\\Program Files\\MySQL\\MySQL Server 5.7\\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 != 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-group-commit-sync-delay=\#  
                      The number of microseconds the server waits for the  
                      binary log group commit sync queue to fill before  
                      continuing. Default: 0. Min: 0. Max: 1000000.  
  --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: (1) All binary logs were generated by MySQL 5.7.5  
                      or older, and GTID\_MODE was ON for some binary logs but  
                      OFF for the newest binary log. (2) The oldest existing  
                      binary log was generated by MySQL 5.7.5 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 (1)  
                      or case (2), 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=\#  
                      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  
  --binlog-transaction-dependency-history-size=\#  
                      Maximum number of rows to keep in the writeset history.  
  --binlog-transaction-dependency-tracking=name  
                      Selects the source of dependency information from which  
                      to assess which transactions can be executed in parallel  
                      by the slave's multi-threaded applier. Possible values  
                      are COMMIT\_ORDER, WRITESET and WRITESET\_SESSION.  
  --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  
  --bootstrap         Used by mysql installation scripts.  
  --bulk-insert-buffer-size=\#  
                      Size of tree cache used in bulk insert optimisation. 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-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  
  --check-proxy-users If set to FALSE (the default), then proxy user identity  
                      will not be mapped for authentication plugins which  
                      support mapping from grant tables.  When set to TRUE,  
                      users associated with authentication plugins which signal  
                      proxy user mapping should be done according to GRANT  
                      PROXY privilege definition.  
  -r, --chroot=name   Chroot mysqld daemon during startup.  
  --collation-server=name  
                      Set the default collation.  
  --completion-type=name  
                      The transaction completion type, one of NO\_CHAIN, CHAIN,  
                      RELEASE  
  --concurrent-insert\[=name\]  
                      Use concurrent insert with MyISAM. Possible values are  
                      NEVER, AUTO, ALWAYS  
  --connect-timeout=\# The number of seconds the mysqld server is waiting for a  
                      connect packet before responding with 'Bad handshake'  
  --console           Write error output on screen; don't remove the console  
                      window on windows.  
  --core-file         Write core on errors.  
  -h, --datadir=name  Path to the database root directory  
  --date-format=name  The DATE format (ignored)  
  --datetime-format=name  
                      The DATETIME format (ignored)  
  --default-authentication-plugin=name  
                      The default authentication plugin used by the server to  
                      hash the password.  
  --default-password-lifetime=\#  
                      The number of days after which the password will expire.  
  --default-storage-engine=name  
                      The default storage engine for new tables

  --delay-key-write\[=name\]  
                      Type of DELAY\_KEY\_WRITE  
  --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. 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=\#  
                      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. This variable is deprecated  
                      along with INSERT DELAYED.  
  --des-key-file=name Load keys for des\_encrypt() and des\_encrypt from given  
                      file.  
  --disable-partition-engine-check  
                      Skip the check for non-natively partitioned tables during  
                      bootstrap. This option is deprecated along with the  
                      partition engine.

  --disabled-storage-engines=name  
                      Limit CREATE TABLE for the storage engines listed  
  --disconnect-on-expired-password  
                      Give clients that don't signal password expiration  
                      support execution time error(s) instead of connection  
                      error  
                      (Defaults to on; use --skip-disconnect-on-expired-password to disable.)  
  --disconnect-slave-event-count=\#  
                      Option used by mysql-test for debugging and testing of  
                      replication.  
  --div-precision-increment=\#  
                      Precision of the result of '/' operator will be increased  
                      on that value  
  --early-plugin-load=name  
                      Optional semicolon-separated list of plugins to load  
                      before storage engine initialization, where each plugin  
                      is identified as name=library, where name is the plugin  
                      name and library is the plugin library in plugin\_dir.  
  --end-markers-in-json  
                      In JSON output ("EXPLAIN FORMAT=JSON" and optimizer  
                      trace), if variable is set to 1, 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  
                      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)  
  -T, --exit-info\[=\#\] Used for debugging. Use at your own risk.  
  --expire-logs-days=\#  
                      If non-zero, binary logs will be purged after  
                      expire\_logs\_days days; 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. The old behavior is deprecated. The  
                      variable can only be set by users having the SUPER  
                      privilege.  
  --external-locking  Use system (external) locking (disabled by default).  
                      With this option enabled you can run myisamchk to test  
                      (not repair) tables while the MySQL server is running.  
                      Disable with --skip-external-locking.  
  --federated\[=name\]  Enable or disable FEDERATED plugin. Possible values are  
                      ON, OFF, FORCE (don't start if the plugin fails to load).  
  --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.  
  --general-log       Log connections and queries to a table or log file.  
                      Defaults to logging to a file hostname.log, or if  
                      --log-output=TABLE is used, to a table mysql.general\_log.  
  --general-log-file=name  
                      Log connections and queries to given file  
  --group-concat-max-len=\#  
                      The maximum length of the result of function  
                      GROUP\_CONCAT()  
  --gtid-executed-compression-period\[=\#\]  
                      When binlog is disabled, a background thread wakes up to  
                      compress the gtid\_executed table every  
                      gtid\_executed\_compression\_period transactions, as a  
                      special case, if variable is 0, 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.  
                      OFF\_PERMISSIVE means that new transactions (committed in  
                      a client session using GTID\_NEXT='AUTOMATIC') are not  
                      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=1. To safely switch from OFF to ON,  
                      first set all servers to OFF\_PERMISSIVE, then set all  
                      servers to ON\_PERMISSIVE, then wait for all transactions  
                      without a GTID to be replicated and executed on all  
                      servers, and finally set all servers to GTID\_MODE = ON.

                      optimization of a query, index range scan will not be  
                      considered for this query. A value of 0 means range

  --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-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
