ctrl+c 退出到终端
#whereis mysql
#find / -name 'my.cnf'
找到哦啊my.cnf在/etc/mysql/my.cnf
#vim /etc/mysql/my.cnf
在【client】下面加入
default-character-set=utf8
在【mysqld】下面加入
default-character-set=utf8
:wq
退出后
#/etc/init.d/mysql restart
提示
root@debian:/# /etc/init.d/mysql restart

这个只是个提示,告诉你在做什么。不管它
再次进去mysql
#mysql -u root -p
#
输入
mysql> show variables like 'collation_%';

修改成功。再次查询数据。就好了
注意 如果修改后不能启动报错
试试把default-character-set=utf8改为character_set_server=utf8 改成后面这个,只需要mysqld下面的.client就不需要加了
5.5后的需要用改成这几个参数
[client] 下面加
default-character-set=utf8
[mysqld]
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci
