character_set_database和character_set_server的编码还是继承自编译的
直接修改配置文件 my.cnf:[mysqld]下添加default-character-set=utf8
$sudo service mysql restart
mysql stop/waiting
start: job failed to start
服务竟然起不来
升级ubuntu12.04以后才第一次碰到
最简单的办法是只要在[mysqld]下再加两条配置即可：加上之后如下
default-storage-engine=innodb 
character-set-server=utf8 
collation-server=utf8_general_ci
$sudo service mysql start
mysql start/running, process 22704
$mysql -u root -p
enter password:
mysql> show variables like 'character%';

编码就顺利改掉了。
