经过本人多次试验，绝对可行的。。。。
登录MySQL,执行编码显示:
showvariableslike'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
修改MySQL默认数据库的编码
需要编辑f文件，如果没有的话执行下面的操作：
1、查找MySQL的cnf文件的位置 find / -iname '*.cnf' -print /usr/share/mysql/my-innodb-heavy-f /usr/share/mysql/my-f /usr/share/mysql/my-f /usr/share/mysql/my-f /usr/share/mysql/my-f /usr/share/texmf/web2c/f /usr/share/texmf/web2c/f /usr/share/texmf/web2c/f /usr/share/texmf/tex/xmltex/f /usr/share/texmf/tex/jadetex/f /usr/share/doc/MySQL-server-community-5.1.22/my-innodb-heavy-f /usr/share/doc/MySQL-server-community-5.1.22/my-f /usr/share/doc/MySQL-server-community-5.1.22/my-f /usr/share/doc/MySQL-server-community-5.1.22/my-f /usr/share/doc/MySQL-server-community-5.1.22/my-f 2、拷贝 f、my-f、my-f、my-innodb-heavy-f其中的一个到/etc下，命名为f cp /usr/share/mysql/my-f /etc/f 3、修改f
vi /etc/f
1、在[client]字段里加入default-character-set=utf8，如下：
[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
default-character-set=utf8
2、在[mysqld]字段里加入character-set-server=utf8，如下：
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
character-set-server=utf8
3、在[mysql]字段里加入default-character-set=utf8，如下：
[mysql]
no-auto-rehash
default-character-set=utf8
修改完成后，service mysql restart重启mysql服务就生效。注意：[mysqld]字段与[mysql]字段是有区别的。这点在网上没人反馈过。
