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

在【mysqld】下面加入

default-character-set=utf8

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
