mysql 存不上汉语

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

二

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

1. 查看表编码：  
2. 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；
