修改mysql数据库为utf8

1.登录MySQL查看用show variables like "character_set%";

现在是gbk

2.修改mysql的my.cnf文件中的字符集键值

[client]

port = 3306
socket = /var/lib/mysql/mysql.sock
default-character-set=utf8  
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
character-set-server=utf8    
[mysql]
no-auto-rehash
default-character-set=utf8

3.修改完成后，service mysql restart重启mysql服务就生效。

更改之后是utf8
