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.
--defaults-extra-file=name
Read this file after the global files are read.
--defaults-file=name Only read default options from the given file name.
--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.
--help Display this help and exit.
--ldata=path The path to the MySQL data directory. Same as --datadir.
--no-defaults Don't read default options from any option file.
--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
