Usage: $0 [OPTIONS]

  --basedir=path       The path to the MySQL installation directory.

  --builddir=path      If using --srcdir with out-of-directory builds, you

                       will need to set this to the location of the build

                       directory where built files reside.

  --cross-bootstrap    For internal use.  Used when building the MySQL system

                       tables on a different host than the target.

  --datadir=path       The path to the MySQL data directory.

  --force              Causes mysql_install_db to run even if DNS does not

                       work.  In that case, grant table entries that normally

                       use hostnames will use IP addresses.

  --ldata=path         The path to the MySQL data directory. Same as --datadir.

  --rpm                For internal use.  This option is used by RPM files

                       during the MySQL installation process.

  --skip-name-resolve  Use IP addresses rather than hostnames when creating

                       grant table entries.  This option can be useful if

                       your DNS does not work.

  --srcdir=path        The path to the MySQL source directory.  This option

                       uses the compiled binaries and support files within the

                       source tree, useful for if you don't want to install

                       MySQL yet and just want to create the system tables.

  --user=user_name     The login username to use for running mysqld.  Files

                       and directories created by mysqld will be owned by this

                       user.  You must be root to use this option.  By default

                       mysqld runs using your current login name and files and

                       directories that it creates will be owned by you.

All other options are passed to the mysqld program
