windows中mysql5.5.10默认字符集修改，字符编码设置，中文乱码，gb2312，gbk，utf8格式存储数据

通过修改mysql默认字符集，可以存储中文数据，以免出现中文乱码，以下以设置为utf8为例。

=================================================================================

以下内容是在本机安装的mysql-5.5.10上,没有修改my.ini前显示结果
===================================================================================

 mysql> show variables like 'character%';
+--------------------------+---------------------------------+
| Variable_name            | Value                           |
+--------------------------+---------------------------------+
| character_set_client     | gbk                             |
| character_set_connection | gbk                             |
| character_set_database   | latin1                          |
| character_set_filesystem | binary                          |
| character_set_results    | gbk                             |
| character_set_server     | latin1                          |
| character_set_system     | utf8                            |
| character_sets_dir       | D:\mysql-5.5.10\share\charsets\ |
+--------------------------+---------------------------------+
8 rows in set (0.02 sec)

mysql> show variables like 'collation%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | gbk_chinese_ci    |
| collation_database   | latin1_swedish_ci |
| collation_server     | latin1_swedish_ci |
+----------------------+-------------------+
3 rows in set (0.00 sec)

 

==============================================================================

关闭mysql服务，在mysql安装目录下，my.ini文件进行如下修改，没有则直接进行添加
==============================================================================

[client]
#修改客户端默认字符编码格式为utf8
default-character-set=utf8
[mysqld]
#修改服务器端默认字符编码格式为utf8
character-set-server = utf8

 

=============================================================================

修改后，再次输入命令查看，显示结果如下
==============================================================================

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       | D:\mysql-5.5.10\share\charsets\ |
+--------------------------+---------------------------------+
8 rows in set (0.00 sec)
