owners.
Starts the MySQL database server.
Usage: /usr/local/libexec/mysqld [OPTIONS]
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/etc/my.cnf /usr/local/etc/mysql/my.cnf ~/.my.cnf
The following groups are read: mysqld server mysqld-5.5
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=#

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

How long a INSERT DELAYED thread should wait for INSERT
statements before terminating
--delayed-queue-size=#

error.
-l, --log[=name] Log connections and queries to file (deprecated option,
use --general-log/--general-log-file instead).
--log-bin[=name] Log update queries in binary format. 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

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

Maximum space to use for all relay logs
--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.

original. Example:
replicate-rewrite-db=master_db_name->slave_db_name.
--replicate-same-server-id

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

files within specified directory
--server-id=# Uniquely identifies the server instance in the community
of replication partners
--show-slave-auth-info

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

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. In STRICT mode, replication will
stop on any unexpected difference between the master and
the slave
--slave-load-tmpdir=name
The location where the slave should put its temporary
files when replicating a LOAD DATA INFILE command

--slave-skip-errors=name
Tells the slave thread to continue replication when a
query event returns an error from the provided list
--slave-transaction-retries=#
Number of times the slave SQL thread will retry a
transaction in case it failed with a deadlock or elapsed
lock wait timeout, before giving up and stopping
--slave-type-conversions=name
Set of slave type conversions that are enabled. 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. Must be enabled to activate
other slow log options
--slow-query-log-file=name
Log slow queries to given log file. Defaults logging to
hostname-slow.log. Must be enabled to activate other slow
log options
--socket=name Socket file to use for connection
--sort-buffer-size=#
Each thread that needs to do a sort allocates a buffer of
this size
--sporadic-binlog-dump-fail
Option used by mysql-test for debugging and testing of
replication.
--sql-mode=name Syntax: sql-mode=mode[,mode[,mode...]]. See the manual
for the complete list of valid sql modes
--ssl Enable SSL for connection (automatically enabled with
other flags).
--ssl-ca=name CA file in PEM format (check OpenSSL docs, implies --ssl)
--ssl-capath=name CA directory (check OpenSSL docs, implies --ssl)
--ssl-cert=name X509 cert in PEM format (implies --ssl)
--ssl-cipher=name SSL cipher to use (implies --ssl)
--ssl-key=name X509 key in PEM format (implies --ssl)
--stored-program-cache=#
The soft upper limit for number of cached stored routines
for one connection.
-s, --symbolic-links
Enable symbolic link support.
(Defaults to on; use --skip-symbolic-links to disable.)
--sync-binlog=# Synchronously flush binary log to disk after every #th
event. Use 0 (default) to disable synchronous flushing
--sync-frm Sync .frm files to disk on creation
(Defaults to on; use --skip-sync-frm to disable.)
--sync-master-info=#
Synchronously flush master info to disk after every #th
event. Use 0 (default) to disable synchronous flushing
--sync-relay-log=# Synchronously flush relay log to disk after every #th
event. Use 0 (default) to disable synchronous flushing
--sync-relay-log-info=#
Synchronously flush relay log info to disk after every
#th transaction. Use 0 (default) to disable synchronous
flushing
--sysdate-is-now Non-default option to alias SYSDATE() to NOW() to make it
safe-replicable. Since 5.0, SYSDATE() returns a `dynamic'
value different for different invocations, even within
the same statement.
--table-cache=# Deprecated; use --table-open-cache instead.
--table-definition-cache=#
The number of cached table definitions
--table-open-cache=#
The number of cached open tables
--tc-heuristic-recover=name
Decision to use in heuristic recover process. Possible
values are COMMIT or ROLLBACK.
--temp-pool This option is ignored on this OS.
(Defaults to on; use --skip-temp-pool to disable.)
--thread-cache-size=#
How many threads we should keep in a cache for reuse
--thread-concurrency=#
Permits the application to give the threads system a hint
for the desired number of threads that should be run at
the same time
--thread-handling=name
Define threads usage for handling queries, one of
one-thread-per-connection, no-threads, loaded-dynamically
--thread-stack=# The stack size for each thread
--time-format=name The TIME format (ignored)
--timed-mutexes Specify whether to time mutexes (only InnoDB mutexes are
currently supported)
--tmp-table-size=# If an internal in-memory temporary table exceeds this
size, MySQL will automatically convert it to an on-disk
MyISAM table
-t, --tmpdir=name Path for temporary files. Several paths may be specified,
separated by a colon (:), in this case they are used in a
round-robin fashion
--transaction-alloc-block-size=#
Allocation block size for transactions to be stored in
binary log
--transaction-isolation=name
Default transaction isolation level.
--transaction-prealloc-size=#
Persistent buffer for transactions to be stored in binary
log
--updatable-views-with-limit=name
YES = Don't issue an error message (warning only) if a
VIEW without presence of a key of the underlying table is
used in queries with a LIMIT clause for updating. NO =
Prohibit update of a VIEW, which does not contain a key
of the underlying table and the query uses a LIMIT clause
(usually get from GUI tools)
-u, --user=name Run mysqld daemon as user.
-v, --verbose Used with --help option for detailed help.
-V, --version Output version information and exit.
--wait-timeout=# The number of seconds the server waits for activity on a
connection before closing it
