【今天为了解决这个字符默认编码的问题花费了将近3个小时。由于版本不同，网上给出的修改方式不尽适用于此版本。特将该版本修改字符编码方式记录如下，以供他人参考】
1、
当我们把zip文件格式解压到指定目录后，并且完成基本环境配置后，打开mysql 5.6.24会发现名为【my-default.ini】的文件。我们用记事本打开该文件会发现并没有【default-character-set = xxx】或者【character_set_server=xxx】，怎么回事呢？网上给出的许多方法都是直接修改这句话的xxx为utf8，不急，下面请看第二步：
2、
复制该文件，并且命名为【my.ini】，这样根目录下就有两个.ini文件了，一个是my-default.ini，一个是my.ini 。接下来我们只需修改my.ini里面的内容就行了。请看第三步：
3、
修改【my.ini】,
在[mysqld]下面添加 character_set_server=utf8，注意是【utf8】不是【utf-8】而且后面没有任何标点符号；
在【sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES】这句话后面再添加三行：
[client]
port=3306
default-character-set=utf8
4、
经过以上三步就ok了。保存后重启服务器，登陆后在命令行输入：【show variables like 'char%';】可查看默认字符集如下图所示：
5、
我的【my.ini】代码，红色代码区为修改之处：
