[Ubuntu][MySQL]修改MySQL编码

MySQL
主要配置文件位置:/etc/mysql/my.cnf.
数据库表文件夹:/var/lib/mysql/,相当于Windows下MySQL的date文件夹

登录MySQL,执行编码显示:

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

修改MySQL默认数据库的编码
需要编辑my.cnf文件,Windows可以直接用Ｍysql Server Instance Config Wizard 进行设置

sudo gedit /etc/mysql/my.cnf

找到[client] 添加:

default-character-set=utf8 //默认字符集为utf8

找到[mysqld] 添加:

 //默认字符集为utf8
default-character-set=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
init_connect='SET NAMES utf8'

修改好后,重新启动mysql 即可.

查询一下show variables like 'character%';
