注：在启动MySQL服务时，会按照一定次序搜索my.cnf，先在/etc目录下找，找不到则会搜索"$basedir/my.cnf"，在本例中就是 /usr/local/mysql/my.cnf，这是新版MySQL的配置文件的默认位置！
注意：在CentOS 6.4版操作系统的最小安装完成后，在/etc目录下会存在一个my.cnf，需要将此文件更名为其他的名字，如：/etc/my.cnf.bak，否则，该文件会干扰源码安装的MySQL的正确配置，造成无法启动。
在使用"yum update"更新系统后，需要检查下/etc目录下是否会多出一个my.cnf，如果多出，将它重命名成别的。否则，MySQL将使用这个配置文件启动，可能造成无法正常启动等问题。
