       --ansi Use ANSI SQL syntax instead of MySQL  syntax.  See  section  5.2
              Running MySQL in ANSI Mode.

              Path  to  installation directory. All paths are usually resolved
              relative to this.

              Allow big result sets by saving all temporary sets on  file.  It
              solves most ’table full’ errors, but also slows down the queries
              where in-memory tables  would  suffice.  Since  Version  3.23.2,
              MySQL is able to solve it automaticaly by using memory for small
              temporary tables and switching to disk tables where necessary.

              IP address to bind to.

              Directory where character  sets  are.  See  section  10.1.1  The
              Character Set Used for Data and Sorting.

              Chroot   mysqld  daemon  during  startup.  Recommended  security
              measure. It will somewhat limit LOAD DATA INFILE and SELECT  ...
              INTO OUTFILE though.

              Path to the database root.

              Set  the default character set. See section 10.1.1 The Character
              Set Used for Data and Sorting.

              Set the default table type for tables. See section 8 MySQL Table

              Don’t flush key buffers between writes for any MyISAM table. See
              Mysql Manual section 12.2.3 Tuning Server Parameters.

              Enable system locking.

              Print some debug info at exit.

              Flush all changes to disk after each SQL command. Normally MySQL
              only  does a write of all changes to disk after each SQL command
              and lets the operating system handle the syncing  to  disk.  See
              section 20.2 What to Do if MySQL Keeps Crashing.

              Display short help and exit.

              Read SQL commands from this file at startup.

              Client  error messages in given language. May be given as a full
              path. See Mysql Manual section 10.1 What Languages Are Supported
              by MySQL?.

              Log connections and queries to file.

              Log  all  ISAM/MyISAM  changes to file (only used when debugging

              Log all  queries  that  have  taken  more  than  long_query_time
              seconds  to  execute  to file. See Mysql Manual section 21.5 The
              Slow Query Log.

              Log updates to file.# where # is a unique number if  not  given.
              See Mysql Manual section 21.3 The Update Log.

              Log  some  extra  information  to  update  log. If you are using
              --log-slow-queries then queries that are not using  indexes  are
              logged to the slow query log.

              Table-modifying   operations  (INSERT/DELETE/UPDATE)  will  have
              lower priority than selects. It can also be done via  {INSERT  |
              REPLACE  |  UPDATE  |  DELETE}  LOW_PRIORITY  ...  to  lower the
              priority   of   only   one   query,    or    by    SET    OPTION
              SQL_LOW_PRIORITY_UPDATES=1 to change the priority in one thread.
              See Mysql Manual section  12.2.9 Table Locking Issues.

              Lock the mysqld process in  memory.  This  works  only  if  your
              system supports the mlockall() system call. This may help if you
              have a problem where the operating system is causing  mysqld  to
              swap on disk.

          --myisam-recover  [=option[,option...]]]  where  option  is  one  of
              If  this  option is used, mysqld will on open check if the table
              is marked as crashed or if if the table wasn’t  closed  properly
              (The   last   option   only   works  if  you  are  running  with
              --skip-locking). If this is the case mysqld will  run  check  on
              the  table.  If  the table was corrupted, mysqld will attempt to
              repair it. The following options affects how the  repair  works.
              DEFAULT  The  same as not giving any option to --myisam-recover.
              BACKUP If the data table was  changed  during  recover,  save  a
              backup     of     the     ‘table_name.MYD’    data    file    as
              ‘table_name-datetime.BAK’.  FORCE Run recover even  if  we  will
              loose  more  than one row from the .MYD file.  QUICK Don’t check
              the rows in the table if there isn’t any delete blocks.   Before
              a  table  is  automaticly repaired, mysqld will add a note about
              this in the error log. If you want to be able  to  recover  from
              most  things  without  user  intervention,  you  should  use the
              options BACKUP,FORCE. This will force a repair of a  table  even
              if  some  rows  would  be deleted, but it will keep the old data
              file as a backup so that you can later examine what happened.

              Path to pid file used by mysqld_safe.

              Port number to listen for TCP/IP connections.

              Use the 3.20 protocol  for  compatibility  with  some  very  old
              clients. See Mysql Manual section  4.17.3 Upgrading from Version
              3.20 to Version 3.21.

              Only use one thread  (for  debugging  under  Linux).  See  Mysql
              Manual section  H.1 Debugging a MySQL server.

       -O| --set-variable var=option
              Give  a variable a value. --help lists variables. You can find a
              full description for all variables in the SHOW VARIABLES section
              in this manual. See Mysql Manual section  7.28.4 SHOW VARIABLES.
              The tuning server parameters section includes information of how
              to  optimize  these.  See  Mysql  Manual  section  12.2.3 Tuning
              Server Parameters.

              This option causes the server not to use the privilege system at
              all.  This gives everyone full access to all databases! (You can
              tell a running server to start using the grant tables  again  by
              executing mysqladmin flush-privileges or mysqladmin reload.)

              Skip some optimize stages. Implies --skip-delay-key-write.

              IP  numbers  returned  by  the  gethostbyname()  system call are
              checked to make sure they resolve back to the original hostname.
              This makes it harder for someone on the outside to get access by
              pretending to be another host. This option also adds some sanity
              checks  of  hostnames.  The  option  is turned off by default in
              MySQL Version 3.21 because sometimes it takes  a  long  time  to
              perform   backward   resolutions.   MySQL  Version  3.22  caches
              hostnames (unless --skip-host-cache is used) and has this option
              enabled by default.

              Turn  off  the  ability to select and insert at the same time on
              MyISAM tables. (This is only to be used if you  think  you  have
              found a bug in this feature).

              Ignore  the  delay_key_write  option  for  all tables. See Mysql
              Manual section  12.2.3 Tuning Server Parameters.

              Don’t use system locking. To use isamchk or myisamchk  you  must
              shut  down  the server. See Mysql Manual section  1.6 How Stable
              Is MySQL?. Note that in MySQL Version 3.23 you  can  use  REPAIR
              and CHECK to repair/check MyISAM tables.

              Hostnames  are not resolved. All Host column values in the grant
              tables must be IP numbers or localhost.

              Don’t listen for TCP/IP connections at all. All interaction with
              mysqld  must  be  made  via  Unix sockets. This option is highly
              recommended for systems where only local requests  are  allowed.
              However,   this  option  is  unsuitable  for  systems  that  use
              MIT-pthreads, because the MIT-pthreads package  doesn’t  support
              Unix sockets.

              Don’t    use    new,    possible    wrong    routines.   Implies

              Never use host name cache for  faster  name-ip  resolution,  but
              query DNS server on every connect instead.

              Don’t  allow  ’SHOW  DATABASE’  commands,  unless  the  user has
              process privilege.

              Disable using thread priorities for faster response time.

              Socket file to use for  local  connections  instead  of  default

              Path  for temporary files. It may be useful if your default /tmp
              directory resides on a partition too  small  to  hold  temporary

              Run  mysqld  daemon  as user user_name. This option is mandatory
              when starting mysqld as root.

              Output version information and exit.
