Django框架报错“_mysql_exceptions.Warning: Incorrect string value:”解决方法

在使用Django连到我的VPS上的MySQL数据库，在插入数据时，报了这样一个错误：“_mysql_exceptions.Warning: Incorrect string value: ‘xE6xB5x81xE8xA1x8C…’ for column ‘name’ at row 1”。
我使用了中文的数据，看起来就是一个字符集不兼容的错误；Django默认使用UTF-8，而mysqld那边配置是默认使用了latin1 – default collation 。
解决办法如下：
1. 修改 /etc/my.cnf 配置文件，然后重启mysqld。
在[client]下配置：default-character-set=utf8
在[mysqld]下配置：
default-character-set=utf8
init_connect=’SET NAMES utf8′
注意：新版MySQL(如：5.5）或MariaDB等，mysqld启动时可能会遇到“[ERROR] /usr/libexec/mysqld: unknown variable ‘default_character_set=utf8’”的错误；就应该在[mysqld]中用 character_set_server=utf8 替换掉 default_character_set=utf8 。
2.如果还没有解决，那么就得删掉原来建的DB，重新建并制定字符集为utf8，如：CREATE DATABASE `jay_db` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
附我遇到的报这个错的堆栈信息：
