  6. #
  7. # Installation Instructions
  8. # ----------------------------------------------------------------------
  9. #
  10. # On Linux you can copy this file to /etc/my.cnf to set global options,
  11. # mysql-data-dir/my.cnf to set server-specific options
  12. # (@localstatedir@ for this installation) or to
  13. # ~/.my.cnf to set user-specific options.
  14. #
  15. # On Windows you should keep this file in the installation directory
  16. # of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
  17. # make sure the server reads the config file use the startup option
  18. # "--defaults-file".
  19. #
  20. # To run run the server from the command line, execute this in a
  21. # command line shell, e.g.
  22. # mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
  23. #
  24. # To install the server as a Windows service manually, execute this in a
  25. # command line shell, e.g.
  26. # mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
  27. #
  28. # And then execute this in a command line shell to start the server, e.g.
  29. # net start MySQLXY
  30. #
  31. #
  32. # Guildlines for editing this file
  33. # ----------------------------------------------------------------------
  34. #
  35. # In this file, you can use all long options that the program supports.
  36. # If you want to know the options a program supports, start the program
  37. # with the "--help" option.
  38. #
  39. # More detailed information about the individual options can also be
  40. # found in the manual.
