Starts the MySQL database server

Usage: /usr/libexec/mysqld [OPTIONS]

Default options are read from the following files in the given order:
/etc/my.cnf ~/.my.cnf /etc/my.cnf 
The following groups are read: mysqld server mysqld-5.0
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 options file
--defaults-file=#	Only read default options from the given file #
--defaults-extra-file=# Read this file after the global files are read

  -?, --help          Display this help and exit.
  --abort-slave-event-count=#

                      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-datbase 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 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.

                      tunnel from the master or other clients to the slave. If
                      not sure, leave this option unset.

  --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

                      What size queue (in rows) should be allocated for
                      handling INSERT DELAYED. If the queue becomes full, any

  --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. Smaller values 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
                      MAX_TABLES+2, the optimizer will switch to the original
                      find_best (used for testing/comparison).
