文章详细的介绍了解决mysql的默认字符编码和中文乱码问题 ,有需要了解的朋友可参考一下。

MySQL的默认编码是Latin1,不支持中文,那么如何修改MySQL的默认编码呢,下面以UTF-8为例来说明

启动mysql后,以root登录mysql
mysql > show variables like 'character%';  #执行编码显示
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
这是安装后,默认的字符编码(图为Solaris下的截图,windows的类似)

需要注意的是,要修改的地方非常多,相应的修改方法也很多。下面是一种最简单最彻底的方法:

一、Windows
1、中止MySQL服务
2、在MySQL的安装目录下找到my.ini,如果没有就把my-medium.ini复制为一个my.ini即可
3、打开my.ini以后,在[client]和[mysqld]下面均加上default-character-set=utf8,保存并关闭
4、启动MySQL服务

二、Linux
1、中止MySQL服务(bin/mysqladmin -u root shutdown -p)
2、在/etc/下找到my.cnf,如果没有就把MySQL的安装目录下的support-files目录下的my-large.cnf复制到/etc/下并改名为my.cnf即可
3、打开my.cnf以后,修改以下,保存并关闭

         找到客户端配置[client] 在下面添加
        default-character-set=utf8 默认字符集为utf8
        在找到[mysqld] 添加
        default-character-set=utf8 默认字符集为utf8
        init_connect='SET NAMES utf8' (设定连接mysql时使用utf8编码,以让mysql数据库为utf8运行)

4、启动MySQL服务(bin/mysqld_safe &),重新查看编码显示

    mysql > show variables like 'character%'; #执行编码显示
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
修改后的编码显示(图为Solaris下的截图,windows的类似)

非常简单,这样的修改一劳永逸,今后MySQL一切相关的默认编码均为UTF-8了,创建新表格的时候无需再次设置
