# Example MySQL config file for small systems.#数据库最小系统配置文件样例
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.#这个配置时为内存比较小的系统且数据库不连续使用的系统设置的，
#最重要的时它的后台服务几乎不会使用太多资源
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html#数据库程序寻找调度平台可以调度的一些位置的选项文件。
#你可以把选项文件复制到这些位置
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.#在这个文件中，你可以使用程序支持的所有长选项。
#如果你想只知道程序支持哪个选项，运行程序查找帮助
