如 default-character-set = utf8
character_set_server = utf8
修改完后，重启mysql的服务，service mysql restart
使用 mysql> SHOW VARIABLES LIKE ‘character%’;查看，发现数据库编码均已改成utf8
+————————–+———————————+
| 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 | D:”mysql-5.0.37″share”charsets” |
+————————–+———————————+
2、还有一种修改字符集的方法，就是使用mysql的命令
mysql> SET character_set_client = utf8 ;
mysql> SET character_set_connection = utf8 ;
mysql> SET character_set_database = utf8 ;
mysql> SET character_set_results = utf8 ;
mysql> SET character_set_server = utf8 ;
mysql> SET collation_connection = utf8 ;
mysql> SET collation_database = utf8 ;
mysql> SET collation_server = utf8 ;
3、一般就算设置了表的默认字符集
为utf8并且通过UTF-8编码发送查询，你会发现存入数据库的仍然是乱码。问题就出在这个connection连接层上。解决方法是在发送查询前执行一下下面这句：
SET NAMES ‘utf8’;
它相当于下面的三句指令：
SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;gaodaima.com
