电脑死机重启后，再开机打开xampp，mysql就无法启动了。
xampp上的错误日志

大概意思是mysql启动失败，提示可能是端口被占用，缺少依赖，权限问题，电脑死机或者其他任何导致关机都可能是原因，等于啥都没说，端口确认是没有占用的，我这个情况显然是因为之前的电脑死机导致的。
提示查看错误日志。下面查看mysql的启动错误日志。

从这上面看不出来到底哪里报错了，没有什么大问题。
进入到xampp下的mysql的bin文件夹，我这边是D:\xampp72\mysql\bin运行mysqld --console。
我在Windows 7 32位上安装Xampp。当我尝试在XAMPP控制面板(v3.2.1)中启动MySql时，我有以下消息，MySql不启动。
23:02:03 [mysql] Problem detected! 23:02:03 [mysql] Port 3306 in use by ""C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld" --defaults-file="C:\Program Files\MySQL\MySQL Server 5.1\my.ini" MySQL"! 23:02:03 [mysql] MySQL WILL NOT start without the configured ports free! 23:02:03 [mysql] You need to uninstall/disable/reconfigure the blocking application 23:02:03 [mysql] or reconfigure MySQL and the Control Panel to listen on a different port 23:02:03 [mysql] Attempting to start MySQL service...
一个类似的问题报告here，但没有工作的答案。当我试图安装与MySql禁用，结果是，我甚至没有一个选项，甚至尝试运行它。
我是新到Xampp，不知道在哪里和寻找什么来解决这个问题
我需要运行Apache和MySql与Php。
mysql启动解决方案
您已经在此机器上安装了一个使用端口3306的mySQL版本。进入最新的my.ini文件，将端口更改为3307.重新启动mySQL服务，看看是否出现。
