mysql数据库编码修改

在linux下修改3个my.cnf的1个/etc/mysql/my.cnf文件

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数据库时使用utf8编码,以让mysql数据库为utf8运行)

修改好后,重新启动mysql 即可,查询一下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/ |
+--------------------------+----------------------------+

此方法用于标准mysql版本同样有效,对于/etc/my.cnf文件,需要从mysql/support-files的文件夹cp my-large.cnf一份到/etc/my.cnf
