mysql启动报错问题

新安装的一台Centos服务器，安装完lamp后，重启了一下系统，发现mysql启动不了并报如下的错误：

/etc/init.d/mysqld start

Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/feixiag.pid).

查看日志如下：

InnoDB: Apply batch completed

150318 17:28:05 mysqld_safe mysqld from pid file /var/lib/mysql/feixiag.pid ended

google,百度后，也没有找到好的方法，突然想起，我在初始化数据库的时候指定了datadir的路径为/data/mysql，而在/etc/my.cnf中的datadir没有修改指定的路径。

查看/etc/my.cnf，果然是没有更改，改为datadir=/data/mysql 后，启动成功。

注：my.conf里面的内容除需要外，其它的最好都注释掉。
