《Mysql必读Linux下MySQL 5.5/5.6的修改字符集编码为UTF8的方法》要点：
本文介绍了Mysql必读Linux下MySQL 5.5/5.6的修改字符集编码为UTF8的方法，希望对您有用。如果有疑问，可以联系我们。
一、登录MySQL查看用SHOW VARIABLES LIKE ‘character%'; 下字符集,显示如下：MYSQL必读
+--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+
character_set_database和character_set_server的默认字符集还是latin1.MYSQL必读
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)：MYSQL必读
1、在[client]字段里加入default-character-set=utf8,如下：MYSQL必读
[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：MYSQL必读
[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必读
[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.MYSQL必读
使用SHOW VARIABLES LIKE ‘character%';查看,发现数据库编码全已改成utf8.MYSQL必读
+--------------------------+----------------------------+ | 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/ | +--------------------------+----------------------------+
