怎么修改mysql数据库的默认编码？

在windows系统下修改mysql默认编码时可以采用不同的方法,主要还是因为windows有配置这一功能,如下:

Mysql Server Instance Config Wizard

但是在Linux下就没有了,采用如下方法:

先show variables like‘character%’;

结果如下:

mysql>show variables like'character%';

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

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/|

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

当然如果里面是utf8的话就不用改了…

有三个地方需要动的

[client]下面加上

default-character-set=utf8

[mysqld]下面加上

default-character-set=utf8

init_connect='SET NAMES utf8'

然后再看一下变量

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

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/|

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

可以看一下手册关于系统变量的部分.有的配置在配置文件和使用show variables都看不到.但是可以设置
