命令:show variables like 'character%';
如下是客户端命令行修改方式,不推荐使用
mysql> set character_set_client=utf8 ;
mysql> set character_set_connection=utf8 ;
mysql> set character_set_database=utf8 ;
mysql> set character_set_database=utf8 ;
mysql> set character_set_results=utf8 ;
mysql> set character_set_server=utf8 ;
mysql> set character_set_system=utf8 ;
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| 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/ |

一般来说,通过这种方法来修改字符编码
修改字符编码必须要修改mysql的配置文件my.cnf,然后重启才能生效
通常需要修改my.cnf的如下几个地方:
【client】下面,加上default-character-set=utf8,或者character_set_client=utf8
【mysqld】下面,加上character_set_server = utf8 ;
