修改mysql字符编码出现Job failed to start解决办法

从网上找到如下资料：
$sudo gedit /etc/mysql/my.cnf
[client]下添加：


default-character-set=utf8


[mysqld]下添加：


default-character-set=utf8


        然后保存退出


$ /etc/init.d/mysql restart


        结果出现了:


Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop mysql ; start mysql. The restart(8) utility is also available.
start: Job failed to start

可能是版本的问题，查5.5以后的版本对字符编码方式修改的办法，发现[mysqld]修改方法变了：


[mysqld]下添加的应该为：


character-set-server=utf8


collation-server=utf8_general_ci


保存退出


$ /etc/init.d/mysql restart


成功


进入MySQL控制台：


    show variables like 'character%';
