1.以root登陆，在终端输入命令 sudo gedit /etc/mysql/my.cnf在打开的文件中

找到［client]在下面加入

default-character-set=utf8

找到 [mysqld_safe]在下面加入

default-character-set=utf8

找到[mysqld]在下面加入，12.04以后

character-set-server=utf8

init_connect='SET NAMES utf8'

或者12.04以前

default-character-set=utf8

init_connect='SET NAMES utf8'

  找到［mysql］在下面加入

  default-character-set=utf8

2.重启mysql命令以便让你上面的修改生效

停用命令：sudo mysqladmin shutdown -u root -p

启用命令：sudo /etc/init.d/mysql restart

或者：sudo mysqld_safe -user=mysql &

3.查看现在mysql的编码

进入mysql命令：sudo mysql －u root -p

检查mysql字符集命令：show variables like 'character%';
