修改/etc/mysql/my.cnf
On MySQL 5.5 I have in my.cnf

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci' 
init_connect='SET NAMES utf8' character-set-server=utf8 collation-server=utf8_unicode_ci skip-character-set-client-handshake

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

Result is

mysql> show variables like "%character%";show variables like "%collation%";
