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. --activate-all-roles-on-login Automatically set all granted roles as active after the user has authenticated successfully. --admin-address=name IP address to bind to for service connection. Address can be an IPv4 address, IPv6 address, or host name. Wildcard values *, ::, 0.0.0.0 are not allowed. Address value can have following optional network namespace separated by the delimiter / from the address value. E.g., the following value 192.168.1.1/red specifies IP addresses to listen for incoming TCP connections that have to be placed into the namespace 'red'. Using of network namespace requires its support from underlying Operating System. Attempt to specify a network namespace for a platform that doesn't support it results in error during socket creation. --admin-port=# Port number to use for service connection, built-in default (33062) --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'. --appliedindex-force-delay[=#] force set a smaller appliedindex --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(es) to bind to. Syntax: address[,address]..., where address can be an IPv4 address, IPv6 address, host name or one of the wildcard values *, ::, 0.0.0.0. In case more than one address is specified in a comma-separated list, wildcard values are not allowed. Every address can have optional network namespace separated by the delimiter / from the address value. E.g., the following value 192.168.1.1/red,172.16.1.1/green,193.168.1.1 specifies three IP addresses to listen for incoming TCP connections two of that have to be placed in corresponding namespaces: the address 192.168.1.1 must be placed into the namespace red and the address 172.16.1.1 must be placed into the namespace green. Using of network namespace requires its support from underlying Operating System. Attempt to specify a network namespace for a platform that doesn't support it results in error during socket creation. --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-encryption Enable/disable binary and relay logs encryption. --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-expire-logs-seconds=# If non-zero, binary logs will be purged after binlog_expire_logs_seconds seconds; If both this option and expire_logs_days are set to non-zero values, this option takes priority. Purges happen at startup and at binary log rotation. --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-rotate-encryption-master-key-at-startup Force binlog encryption master key rotation at startup --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 (e.g. 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-row-metadata=name Controls whether metadata is logged using FULL or MINIMAL format. FULL causes all metadata to be logged; MINIMAL means that only metadata actually required by slave is logged. Default: MINIMAL. --binlog-row-value-options=name When set to PARTIAL_JSON, this option enables a space-efficient row-based binary log format for UPDATE statements that modify a JSON value using only the functions JSON_SET, JSON_REPLACE, and JSON_REMOVE. For such updates, only the modified parts of the JSON document are included in the binary log, so small changes of big documents may need significantly less space. --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. --block-encryption-mode=name mode for AES_ENCRYPT/AES_DECRYPT --bulk-insert-buffer-size=# Size of tree cache used in bulk insert optimisation. Note that this is a limit per thread! --caching-sha2-password-private-key-path=name A fully qualified path to the private RSA key used for authentication. --caching-sha2-password-public-key-path=name A fully qualified path to the public RSA key used for authentication. --ccl-max-waiting-count=# max waiting count in one ccl rule or bucket --ccl-queue-bucket-count=# How many groups when use ccl queue --ccl-queue-bucket-size=# The max concurrency allowed when use ccl queue --ccl-wait-timeout=# Timeout in seconds to wait when concurrency control. --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. --client-endpoint-ip=name The endpoint ip that client use to connect. --cluster-current-term=# Normandy cluster nodes current term information --cluster-dump-meta Normandy cluster dump meta --cluster-force-change-meta Normandy cluster force to change meta --cluster-force-recover-index=# Normandy cluster restore from leader set apply index point --cluster-force-single-mode Normandy cluster force to use single mode --cluster-id=# cluster id --cluster-info=name Normandy cluster nodes ip-port information --cluster-learner-node Normandy cluster learner node type --cluster-log-type-node Normandy cluster log type instance --cluster-mts-recover-use-index Normandy cluster use idex to recover mts (Defaults to on; use --skip-cluster-mts-recover-use-index to disable.) --cluster-purged-gtid=name Normandy cluster set the purged gtid --cluster-start-index=# Normandy cluster start valid index --collation-server=name Set the default collation. --commit-pos-watcher background thread checking and updating binlog commit position (Defaults to on; use --skip-commit-pos-watcher to disable.) --commit-pos-watcher-interval[=#] interval(us) for background thread commit_pos_watcher --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' --consensus-auto-leader-transfer whether to enable auto leader transfer in consensus layer (Defaults to on; use --skip-consensus-auto-leader-transfer to disable.) --consensus-auto-leader-transfer-check-seconds[=#] the interval between a leader check its health for a transfer --consensus-auto-reset-match-index enable auto reset match index when consensus follower has fewer logs (Defaults to on; use --skip-consensus-auto-reset-match-index to disable.) --consensus-check-commit-index-interval[=#] check interval for slave calling checkCommitIndex --consensus-check-large-event check consensus large event or not (Defaults to on; use --skip-consensus-check-large-event to disable.) --consensus-checksum Checksum when consensus receive log. Disabled by default. --consensus-configure-change-timeout=# Consensus configure change timeout (ms). Default 1 min --consensus-disable-election Disable consensus election and stepdown. Disabled by default. --consensus-disable-fifo-cache disable consensus fifo cache (run with weak consensus mode) --consensus-dynamic-easyindex Enable dynamic easy addr cidx. Enabled by default. (Defaults to on; use --skip-consensus-dynamic-easyindex to disable.) --consensus-election-timeout=# Consensus election timeout --consensus-flow-control[=name] consensus flow control (<-1: no log send, -1: only send log during heartbeat, 0: no flow control, >0: [TODO] flow control). --consensus-force-promote Try to force promote a follower to leader --consensus-force-recovery for innodb_force_recovery --consensus-force-sync-epoch-diff[=#] consensus forceSync epoch diff --consensus-heartbeat-thread-cnt[=#] Number of consensus heartbeat thread --consensus-index-buf-enabled Whether to enable Relay_log_info::consensus_index_buf (Defaults to on; use --skip-consensus-index-buf-enabled to disable.) --consensus-io-thread-cnt[=#] Number of consensus io thread --consensus-large-batch-ratio[=#] Large batch ratio of consensus server send at once --consensus-large-event-limit=# Consensus large event limit --consensus-large-event-split-size[=#] split size for large event, dangerous to change this variable --consensus-large-trx consensus large trx or not (Defaults to on; use --skip-consensus-large-trx to disable.) --consensus-large-trx-split-size=# Max size to split large trx into multi consensus logs.

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; If this option alone is set on the command line or in a configuration file, it overrides the default value for binlog-expire-logs-seconds. If both options are set to nonzero values, binlog-expire-logs-seconds takes priority. 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. (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 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 --force-revise force revise or not --ft-boolean-syntax=name List of operators for MATCH ...

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. -?, --help Display this help and exit. --histogram-generation-max-mem-size=# Maximum amount of memory available for generating histograms --host-cache-size=# How many host names should be cached to avoid resolving. --information-schema-stats-expiry=# The number of seconds after which mysqld server will fetch data from storage engine and replace the data in cache. --init-connect=name Command(s) that are executed for each new connection --init-file=name Read SQL commands from this file at startup --init-slave=name Command(s) that are executed by a slave server each time the SQL thread starts -I, --initialize Create the default database and exit. Create a super user with a random expired password and store it into the log. --initialize-insecure Create the default database and exit. Create a super user with empty password. --interactive-timeout=# The number of seconds the server waits for activity on an interactive connection before closing it --internal-tmp-mem-storage-engine=name The default storage engine for in-memory internal temporary tables. --join-buffer-size=# The size of the buffer that is used for full joins --keep-files-on-create Don't overwrite stale .MYD and .MYI even if no directory is specified --key-buffer-size=# The size of the buffer used for index blocks for MyISAM tables. 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 --keyring-migration-destination=name Keyring plugin to which the keys are migrated to.

If password value is not specified then it will be asked from the tty. --keyring-migration-port=# Port number to use for connection. --keyring-migration-source=name Keyring plugin from where the keys needs to be migrated to. This option must be specified along with --keyring-migration-destination. --keyring-migration-user=name User to login to server. -L, --language=name Client error messages in given language.

Use --lc-messages-dir instead. --large-pages Enable support for large pages --lc-messages=name Set the language used for the error messages. --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 --lock-wait-timeout=# Timeout in seconds to wait for a lock before returning an error. --log-bin[=name] Configures the name prefix to use for binary log files. If the --log-bin option is not supplied, the name prefix defaults to "binlog". If the --log-bin option is supplied without argument, the name prefix defaults to "HOSTNAME-bin", where HOSTNAME is the machine's hostname. To set a different name prefix for binary log files, use --log-bin=name. To disable binary logging, use the --skip-log-bin or --disable-log-bin option. --log-bin-index=name File that holds the names for 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-bin-use-v1-row-events If equal to 1 then version 1 row events are written to a row based binary log. If equal to 0, then the latest version of events are written. This option is useful during some upgrades. --log-error[=name] Error log file --log-error-services=name Services that should be called when an error event is received --log-error-suppression-list=name Comma-separated list of error-codes. Error messages corresponding to these codes will not be included in the error log.

For use in debugging, not production as sensitive information may be logged. --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. (Defaults to on; use --skip-log-slave-updates to disable.) --log-slow-admin-statements Log slow OPTIMIZE, ANALYZE, ALTER and other administrative statements to the slow log if it is open. --log-slow-extra Print more attributes to the slow query log file. Has no effect on logging to table. --log-slow-slave-statements Log slow statements executed by slave thread to the slow log if it is open. --log-statements-unsafe-for-binlog Log statements considered unsafe when using statement based binary logging. (Defaults to on; use --skip-log-statements-unsafe-for-binlog to disable.) --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. --log-throttle-queries-not-using-indexes=# Log at most this many 'not using index' warnings per minute to the slow log. Any further warnings will be condensed into a single summary line. A value of 0 disables throttling. Option has no effect unless --log_queries_not_using_indexes is set. --log-timestamps=name UTC to timestamp log files in zulu time, for more concise timestamps and easier correlation of logs from servers from multiple time zones, or SYSTEM to use the system's local time. This affects only log files, not log tables, as the timestamp columns of the latter can be converted at will. --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 --mandatory-roles=name All the specified roles are always considered granted to every user and they can't be revoked. Mandatory roles still require activation unless they are made into default roles. The granted roles will not be visible in the mysql.role_edges table. --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.

Legal values are: ALL_LOSSY to enable lossy conversions, ALL_NON_LOSSY to enable non-lossy conversions, ALL_UNSIGNED to treat all integer column type data to be unsigned values, and ALL_SIGNED to treat all integer column type data to be signed values. Default treatment is ALL_SIGNED. If ALL_SIGNED and ALL_UNSIGNED both are specified, ALL_SIGNED will take higher priority than ALL_UNSIGNED. 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.

Users with the SUPER privilege are affected, unlike read_only. Setting super_read_only to ON also sets read_only to ON. -s, --symbolic-links Enable symbolic link support (deprecated and will be removed in a future release). --sync-binlog=# Synchronously flush binary log to disk after every #th write to the file. Use 0 to disable synchronous flushing --sync-master-info=# Synchronously flush master info to disk after every #th event.
