Mysql数据库字符集编码的查看与修改

1，查看编码：

                 命令：show variables like 'character%';

如下是客户端命令行修改方式，不推荐使用

mysql> set character_set_client=utf8 ;

mysql> set character_set_connection=utf8 ;

mysql> set character_set_database=utf8 ;

mysql> set character_set_database=utf8 ;

mysql> set character_set_results=utf8 ;

mysql> set character_set_server=utf8 ;

mysql> set character_set_system=utf8 ;

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/ |
+--------------------------+----------------------------+

一般来说，通过这种方法来修改字符编码

修改mysql数据库的字符编码

修改字符编码必须要修改mysql的配置文件my.cnf,然后重启才能生效

通常需要修改my.cnf的如下几个地方：

【client】下面，加上default-character-set=utf8，或者character_set_client=utf8

【mysqld】下面，加上character_set_server = utf8 ；
