修改mysqlcharacter_set_database与character_set_server的默认编码（windows环境）

@参考文章

修改前是这个样子的

mysql> show variables like "%char%";
+--------------------------+---------------------------------------------------------------+
| Variable_name | Value |
+--------------------------+---------------------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | C:\Program Files (x86)\MySQL\MySQL Server 5.5\share\charsets\ |
+--------------------------+---------------------------------------------------------------+
8 rows in set

具体到my.ini中的配置是这样的：

若想更改，手动修改为utf-8好像不起作用。

怎么办呢？在MySQL的安装文件中进入bin目录下，双击MySQLInstanceConfig.exe，重新走一遍server的配置，一切默认就行，只需要在Character Set环节，要选择character为utf8

再来看配置文件：

变成utf-8了，顺道去数据库看看

mysql> show variables like "%char%";
+--------------------------+---------------------------------------------------------------+
| Variable_name | Value |
+--------------------------+---------------------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | C:\Program Files (x86)\MySQL\MySQL Server 5.5\share\charsets\ |
+--------------------------+---------------------------------------------------------------+
8 rows in set

以后再新建数据库默认编码就是utf-8了，还在等什么，赶紧动手试试
