查看Ubuntu下MySQL的配置，使完美支持中文的源代码 0

安装完以后：

 $:mysql -u root -p

查看字符编码初始值：

 mysql> show variables like 'char%';

此时应该是：

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

| 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/ |

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

修改字符集，不然对UTF-8的支持会出问题（[http://jamwiki.org/wiki/en/%E4%B8%AD%E6%96%87 看这里]）：

 $:cd /etc/mysql/

 $:sudo gedit my.cnf

更改或加入：

[mysqld]下

 default-character-set=utf8 

*如果启动不了，提示“mysqld: unknown variable 'default-character-set=utf8'”，则可换成：

 character_set_server=utf8

[client]下

 default-character-set=utf8

[server]下

 default-character-set=utf8，init_connect='SET NAMES utf8;'

保存

重启SQL：

 $:sudo /etc/init.d/mysql restart

查看字符编码初始值：

 mysql> show variables like 'char%';

结果应为：

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

| 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/ |

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

最后，创建DB时最好指明字符属性

 $:create database database-name character set utf8
