XAMPP中apache出现错误 Error: Apache shutdown unexpectedly.

今早上启动XAPMPP中的apache出现以下错误：

Error: Apache shutdown unexpectedly.

10:03:20  [Apache]     This may be due to a blocked port, missing dependencies,
10:03:20  [Apache]     improper privileges, a crash, or a shutdown by another method.
10:03:20  [Apache]     Press the Logs button to view error logs and check
10:03:20  [Apache]     the Windows Event Viewer for more clues

出现以上错误的话，打开E:\php\xampp\apache\conf\extra，这里的前面路径是你安装xampp的路径，然后在里面找到httpd-ssl.conf这个文件，打开，然后找到Listen 443，将其修改为Listen 444，然后重启apache，即可启动成功
