# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# 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
#
# 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.
# The following options will be passed to all MySQL clients
[client]
default-character-set=utf8
#password = your_password
port = 3306
socket = /tmp/mysql.sock
# Here follows entries for some specific programs
# The MySQL server
对在修改mysql配置文件之前，你已经存在的数据库，如果你想要输入中文字段，请对该数据库进行如下修改：
mysql -u 用户名 -p
输入密码
进入mysql
对数据库的表进行更改（此时表的字体还不是utf8）
终端进入mysql
alter table 数据库名.表名 convert to character set utf8 collate utf8_general_ci;
最后对数据库进行修改
alter database 数据库名 default character set utf8 collate utf8_general_ci;
捣鼓这个鬼东西捣鼓了三个小时，差点心态爆炸了。
这样子以后，发现JDBC对数据库的操作，或者是workbench对数据库进行中文字段的操作，都可以成功！！！
