Ubuntu?12.04 MySQL改utf-8 啟動不了

default-character-set=utf8

報錯：

start mysql. The restart(8) utility is also available.
start: Job failed to start

這么寫OK了：　

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

Result is

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