一：
运行环境 ubuntu :14.04
mysql：5.5.47
进入mysql 运行?SHOW VARIABLES LIKE 'character_set_%';查看mysql 的支持的编码格式
+--------------------------+----------------------------+| Variable_name | Value |+--------------------------+----------------------------+| character_set_client | utf8 || character_set_connection | latin || character_set_database | utf8 || character_set_filesystem | binary || character_set_results | latin || character_set_server | utf8 || character_set_system | utf8 || character_sets_dir | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+8 rows in set (0.00 sec)
?
?将所有的格式修改成utf8，修改my.cnf(也可能是my.ini)?
sudo find / -name my.cnf //查看路径/etc/mysql/my.cnf sudo gedit /etc/mysql/my.cnf//打开文件
?
?
?
在?[client] ?[mysql]?[mysqld_safe]下面插入?default-character-set = utf8
? ? 在[mysqld] 下面插入character-set-server=utf8
然后 点击保存
重启mysql?
?
sudo /etc/init.d/mysql restart
再次查看进入mysql 查看编码格式
?
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/ |+--------------------------+----------------------------+8 rows in set (0.00 sec)
这样就 哦可 ?la

如果第一种方法还不性，那就试试这种吧！
1.修改数据库的编码格式
?
//查看数据库编码： mysql> SHOW CREATE DATABASE db_name;
?
+-----------+--------------------------------------------------------------------+| Database | Create Database |+-----------+--------------------------------------------------------------------+| GoodsInfo | CREATE DATABASE `GoodsInfo` /*!40100 DEFAULT CHARACTER SET utf8 */ |+-----------+--------------------------------------------------------------------+1 row in set (0.00 sec)
?如果不是utf8那就删数据库了再来一次?
?
建数据库的时候我们可以通过这样的指令实现数据库的字符集设置：
?
CREATE DATABASE `database` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;?
2.修改表的编码格式
- 查看表编码：??
- mysql> SHOW?CREATE?TABLE?tbl_name;?
如果报错：
ERROR 1046 (3D000): No database selected
执行下面的：
mysql> use db_name;mysql> show create table tbl_name;
?
?
?
修改表的编码方式：ALTER TABLE `test` DEFAULT CHARACTER SET utf8;该命令用于将表test的编码方式改为utf8；
