xampp/apache启动失败解决方法

我的问题是：

9:15:53 AM [Apache] Error: Apache shutdown unexpectedly.

9:15:53 AM [Apache] This may be due to a blocked port, missing dependencies,

9:15:53 AM [Apache] improper privileges, a crash, or a shutdown by another method.

9:15:53 AM [Apache] Press the Logs button to view error logs and check

9:15:53 AM [Apache] the Windows Event Viewer for more clues

9:15:53 AM [Apache] If you need more help, copy and post this

9:15:53 AM [Apache] entire log window on the forums

根据log查找解决方案，

1．80端口冲突，解决方法：

打开目录C:\xampp\apache\conf(我的安装目录为C:\xampp)下的httpd.conf文件，将Listen 80和 ServerName localhost:80中的80改为8081或其它值（尽量不要使用0－1023端口，这个是系统保留端口），要保持一致。

2．监听端口443冲突，解决方法：

打开目录C:\xampp\apache\conf\extra (我的安装目录为C:\xampp)下的httpd-ssl.conf文件，将Listen 443这句注释掉：# Listen 443或将443改为4433或其它值（尽量不要使用0－1023）。

再修改了以上两个端口后，再次启动apache，it works！
