一、登录MySQL查看用SHOW VARIABLES LIKE ‘character%'; 下字符集，显示如下：
+--------------------------+----------------------------+| 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/ |+--------------------------+----------------------------+
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：
[client]port = 3306socket = /var/lib/mysql/mysql.sockdefault-character-set=utf8
[mysqld]port = 3306socket = /var/lib/mysql/mysql.sockcharacter-set-server=utf8
[mysql]no-auto-rehashdefault-character-set=utf8
使用SHOW VARIABLES LIKE ‘character%';查看，发现数据库编码全已改成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 | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+
