Edit File: mysqld--help-notwin.result
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. --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'. --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-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-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. 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-ignore-db=name Tells the master that updates to the given database should not be logged to the binary log. --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-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 --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.

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-storage-engine=name The default storage engine for new tables --default-time-zone=name Set the default time zone. --default-week-format=# The default week format used by WEEK() functions --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 --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.

Deprecated, use --optimizer-switch instead. (Defaults to on; use --skip-engine-condition-pushdown to disable.) --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 --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. --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.

Increase this to get better index handling (for all reads and multiple writes) to as much as you can afford --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 -L, --language=name Client error messages in given language.

Optional (but strongly recommended to avoid replication problems if server's hostname changes) argument should be the chosen location for the binary log files. --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-error[=name] Error log file --log-isam[=name] Log all MyISAM changes to file. --log-output=name Syntax: log-output=value[,value...], where "value" could be TABLE, FILE or NONE --log-queries-not-using-indexes Log queries that are executed without benefit of any index to the slow log if it is open --log-short-format Don't log extra information to update and slow-query logs. --log-slave-updates Tells the slave to log the updates from the slave thread to the binary log. You will need to turn it on if you plan to daisy-chain the slaves --log-slow-admin-statements Log slow OPTIMIZE, ANALYZE, ALTER and other administrative statements to the slow log if it is open. --log-slow-queries[=name] Log slow queries to a table or log file. Defaults logging to table mysql.slow_log or hostname-slow.log if --log-output=file is used. Must be enabled to activate other slow log options. Deprecated option, use --slow-query-log/--slow-query-log-file instead. --log-slow-slave-statements Log slow statements executed by slave thread to the slow log if it is open. --log-tc=name Path to transaction coordinator log (used for transactions that affect more than one storage engine, when binary log is disabled). --log-tc-size=# Size of transaction coordinator log. -W, --log-warnings[=#] Log some not critical warnings to the log file --long-query-time=# Log all queries that have taken more than long_query_time seconds to execute to file. The argument will be treated as a decimal value with microsecond precision --low-priority-updates INSERT/DELETE/UPDATE has lower priority than selects --lower-case-table-names[=#] If set to 1 table names are stored in lowercase on disk and table names will be case-insensitive. Should be set to 2 if you are using a case insensitive file system --master-info-file=name The location and name of the file that remembers the master and where the I/O replication thread is in the master's binlogs. --master-retry-count=# The number of tries the slave will make to connect to the master before giving up. --max-allowed-packet=# Max packet length to send to or receive from the server --max-binlog-cache-size=# Sets the total size of the transactional cache --max-binlog-dump-events=# Option used by mysql-test for debugging and testing of replication. --max-binlog-size=# Binary log will be rotated automatically when the size exceeds this value.

Use thread-handling=no-threads instead. --open-files-limit=# If this is not 0, then mysqld will use this value to reserve file descriptors to use with setrlimit(). If this value is 0 then mysqld will reserve max_connections*5 or max_connections + table_cache*2 (whichever is larger) number of file descriptors --optimizer-prune-level=# Controls the heuristic(s) applied during query optimization to prune less-promising partial plans from the optimizer search space. Meaning: 0 - do not apply any heuristic, thus perform exhaustive search; 1 - prune plans based on number of retrieved rows --optimizer-search-depth=# Maximum depth of search performed by the query optimizer. Values larger than the number of relations in a query 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 will switch to the original find_best search. NOTE: The value 63 and its associated behaviour is deprecated --optimizer-switch=name optimizer_switch=option=val[,option=val...], where option is one of {index_merge, index_merge_union, index_merge_sort_union, index_merge_intersection, engine_condition_pushdown} and val is one of {on, off, default} --performance-schema Enable the performance schema. --performance-schema-events-waits-history-long-size=# Number of rows in EVENTS_WAITS_HISTORY_LONG. --performance-schema-events-waits-history-size=# Number of rows per thread in EVENTS_WAITS_HISTORY. --performance-schema-max-cond-classes=# Maximum number of condition instruments. --performance-schema-max-cond-instances=# Maximum number of instrumented condition objects. --performance-schema-max-file-classes=# Maximum number of file instruments. --performance-schema-max-file-handles=# Maximum number of opened instrumented files. --performance-schema-max-file-instances=# Maximum number of instrumented files. --performance-schema-max-mutex-classes=# Maximum number of mutex instruments. --performance-schema-max-mutex-instances=# Maximum number of instrumented MUTEX objects. --performance-schema-max-rwlock-classes=# Maximum number of rwlock instruments. --performance-schema-max-rwlock-instances=# Maximum number of instrumented RWLOCK objects. --performance-schema-max-table-handles=# Maximum number of opened instrumented tables. --performance-schema-max-table-instances=# Maximum number of instrumented tables. --performance-schema-max-thread-classes=# Maximum number of thread instruments. --performance-schema-max-thread-instances=# Maximum number of instrumented threads. --pid-file=name Pid file used by safe_mysqld --plugin-dir=name Directory for plugins --plugin-load=name Optional semicolon-separated list of plugins to load, where each plugin is identified as name=library, where name is the plugin name and library is the plugin library in plugin_dir. -P, --port=# Port number to use for connection or 0 to default to, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306), whatever comes first --port-open-timeout=# Maximum time in seconds to wait for the port to become free.

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 listening on a non-default port or if you have a special tunnel from the master or other clients to the slave. If not sure, leave this option unset --report-user=name The account user name of the slave to be reported to the master during slave registration --rpl-recovery-rank=# Unused, will be removed --safe-mode Skip some optimize stages (for testing).

All hostnames are IP's or 'localhost'. --skip-networking Don't allow connection with TCP/IP --skip-new Don't use new, possibly wrong routines. --skip-show-database Don't allow 'SHOW DATABASE' commands --skip-slave-start If set, slave is not autostarted. --skip-stack-trace Don't print a stack trace on failure. --skip-thread-priority Don't give threads different priorities. This option is deprecated because it has no effect; the implied behavior is already the default. --slave-compressed-protocol Use compression on master/slave protocol --slave-exec-mode=name Modes for how replication events should be executed. Legal values are STRICT (default) and IDEMPOTENT. In IDEMPOTENT mode, replication will not stop for operations that are idempotent.

Legal values are: ALL_LOSSY to enable lossy conversions and ALL_NON_LOSSY to enable non-lossy conversions. If the variable is assigned the empty set, no conversions are allowed and it is expected that the types match exactly. --slow-launch-time=# If creating the thread takes longer than this value (in seconds), the Slow_launch_threads counter will be incremented --slow-query-log Log slow queries to a table or log file. Defaults logging to a file hostname-slow.log or a table mysql.slow_log if --log-output=TABLE is used.
