修改ubuntu下mysql默认编码

编辑/etc/mysql/my.cnf文件，相当于windows中的my.ini：

找到[client]
添加：

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

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%';
