PS:昨天一同事遇到mysql 5.5中文乱码问题,找我解决。解决了,有个细节问题网上没人说,我就总结一下。

一、登录MySQL查看用SHOW VARIABLES LIKE ‘character%’;下字符集,显示如下:
<br> +--------------------------+----------------------------+<br> | Variable_name | Value |<br> +--------------------------+----------------------------+<br> | character_set_client | utf8 |<br> | character_set_connection | utf8 |<br> | character_set_database | latin1 |<br> | character_set_filesystem | binary |<br> | character_set_results | utf8 |<br> | character_set_server | latin1 |<br> | character_set_system | utf8 |<br> | character_sets_dir | /usr/share/mysql/charsets/ |<br> +--------------------------+----------------------------+<br>
character_set_database和character_set_server的默认字符集还是latin1。

二、最简单的完美修改方法,修改mysql的my.cnf文件中的字符集键值(注意配置的字段细节):

1、在[client]字段里加入default-character-set=utf8,如下:
<br> [client]<br> port = 3306<br> socket = /var/lib/mysql/mysql.sock<br> default-character-set=utf8<br>
2、在[mysqld]字段里加入character-set-server=utf8,如下:
<br> [mysqld]<br> port = 3306<br> socket = /var/lib/mysql/mysql.sock<br> character-set-server=utf8<br>
3、在[mysql]字段里加入default-character-set=utf8,如下:
<br> [mysql]<br> no-auto-rehash<br> default-character-set=utf8<br>
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。

使用SHOW VARIABLES LIKE ‘character%’;查看,发现数据库编码全已改成utf8。
<br> +--------------------------+----------------------------+<br> | Variable_name | Value |<br> +--------------------------+----------------------------+<br> | character_set_client | utf8 |<br> | character_set_connection | utf8 |<br> | character_set_database | utf8 |<br> | character_set_filesystem | binary |<br> | character_set_results | utf8 |<br> | character_set_server | utf8 |<br> | character_set_system | utf8 |<br> | character_sets_dir | /usr/share/mysql/charsets/ |<br> +--------------------------+----------------------------+<br>

4、如果上面的都修改了还乱码,那剩下问题就一定在connection连接层上。解决方法是在发送查询前执行一下下面这句(直接写在SQL文件的最前面):
SET NAMES ‘utf8′;

它相当于下面的三句指令:
<br> SET character_set_client = utf8;<br> SET character_set_results = utf8;<br> SET character_set_connection = utf8;<br>

网上很多其他方法不能彻底解决这个问题,这个可以完美解决!
