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'.
 --auto-increment-increment[=#] 
 Auto-increment columns are incremented by this
 --auto-increment-key-high-priority 
 whether choose auto increment key as high priority key
 when the table do not contain primary key and not
 nullable unique key in the process of slave applying
 events
 (Defaults to on; use --skip-auto-increment-key-high-priority to disable.)
 --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 (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-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

 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

 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.

 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.

 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

 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

 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

 Semisync can wait for slave ACKs at one of two
 points,AFTER_SYNC or AFTER_COMMIT. AFTER_SYNC is the
 default value.AFTER_SYNC means that semisynchronous
 replication waits just after the binary log file is
 flushed, but before the engine commits, and so guarantees
 that no other sessions can see the data before replicated
 to slave. AFTER_COMMIT means that semisynchronous
 replication waits just after the engine commits. Other
 sessions may see the data before it is replicated, even
 though the current session is still waiting for the
 commit to end successfully.
