Мой Конфигурационный файл, как спросили, предложите то, что должно быть конфигурацией, я - новичок в mySql установке

Нано GNU 2.5.3 Файлов:/etc/mysql/my.cnf

к одному из:

# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

#
# * IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.
