| 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
 | |
|  --automatic-sp-privileges 
 | |
|  Creating and dropping stored procedures alters ACLs
 | |
|  (Defaults to on; use --skip-automatic-sp-privileges to disable.)
 | |

|  have. This comes into play when the main MySQL thread
 | |
|  gets very many connection requests in a very short time

 | |
|  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 cache to hold the SQL statements for the
 | |
|  binary log during a transaction. If you often use big,
 | |
|  multi-statement transactions 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=# 
 | |

 | |
|  --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
 | |

 | |
|  not sure, leave this option unset

|  is already the default.

 | |
|  --slave-exec-mode=name
