其他的一些设置方法：

修改数据库的字符集
mysql>use mydb
mysql>alter database mydb character set utf-8;
创建数据库指定数据库的字符集
mysql>create database mydb character set utf-8;

通过配置文件修改:
修改/var/lib/mysql/mydb/db.opt
default-character-set=latin1
default-collation=latin1_swedish_ci
为
default-character-set=utf8
default-collation=utf8_general_ci
重起MySQL:
[root@bogon ~]# /etc/rc.d/init.d/mysql restart

通过MySQL命令行修改:
mysql> set character_set_client=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_connection=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_database=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_results=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_server=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_system=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_connection=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_database=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_server=utf8;
Query OK, 0 rows affected (0.01 sec)
查看:
mysql> show variables like 'character_set_%';
