Beginning with MySQL 5.0.4, it is possible to use
option files and

There is no guarantee about the order in which the option files in the directory will be read.
Write the contents of an included option file like any other option file. That is, it should contain groups of
options, each preceded by a
While an included file is being processed, only those options in groups that the current program is
looking for are used. Other groups are ignored. Suppose that a

4.2.3.4. Command-Line Options that Affect Option-File Handling
Most MySQL programs that support option files handle the following options. They affect option-file
handling, so they must be given on the command line and not in an option file. To work properly, each
of these options must be given before other options, with these exceptions:
•
--print-defaults
defaults-extra-file
• On Windows, if the server is started with the
options,
--install
Service".
When specifying file names, you should avoid the use of the "~" shell metacharacter because it might
not be interpreted as you expect.
•
--defaults-extra-file=file_name
Read this option file after the global option file but (on Unix) before the user option file. As of
MySQL 5.0.6, if the file does not exist or is otherwise inaccessible, the program exits with an error.
