上次说了一下C从MySql里面读取数据，这次在介绍一下如何把MySql的字符集设置为utf8
第一：查看自己MySql的字符集
mysql> show variables like 'character%';
看看是否是下面的显示：
+--------------------------+----------------------------+
| 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       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
如果不是就这样改变：
mysql>SET character_set_client=utf8;
mysql>SET character_set_connection=utf8;
mysql>SET character_set_databse=utf8;
mysql>SET character_set_results=utf8;
mysql>SET character_set_server=utf8;
mysql>SET character_set_system=utf8;
mysql> show variables like 'character%';
看看是否改变过来
第二：改变一下MySql的配置文件
cd ／etc／mysql／my.cnf
gedit my.cnf
[client]
port        = 3306
socket        = /var/run/mysqld/mysqld.sock
default-character-set=utf8

[mysqld]
#
# * Basic Settings
#
default-character-set=utf8
init_connect='SET NAMES utf8'
