查看数据库编码如下：

MysqL> show variables like '%char%';

+--------------------------+----------------------------------+

| 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     | latin1                           |

| character_set_system     | utf8                             |

| character_sets_dir       | /usr/local/MysqL/share/charsets/ |

+--------------------------+----------------------------------+

8 rows in set

其中：

character_set_server     | latin1

编码为latin1，数据库出现中文乱码！

解决方法：

修改编码为uft8;

set @@character_set_server='utf8';
