XAMPP安裝好之後啟動，但有些使用者在啟動apache的時候會出現：

11:41:38 [Apache] Status change detected: running
11:41:38 [Apache] Status change detected: stopped
11:41:38 [Apache] Error: Apache shutdown unexpectedly.
11:41:38 [Apache] This may be due to a blocked port, missing dependencies,
11:41:38 [Apache] improper privileges
 
, a crash, or a shutdown by another method.
11:41:38 [Apache] Press the Logs button to view error logs and check
11:41:38 [Apache] the Windows Event Viewer for more clues

錯誤原因

XAMPP的設定的常用埠，包含http和https的埠都被佔用了。

解決辦法

1. 開啟XAMPP的控制面板，找到：Apache的Config檔案；
2. 先開啟 Apache(httpd.conf),找到：Listen 80 替換成：Listen 8080；找到：ServerName localhost:80 替換成：ServerName localhost:8080；儲存。
3. 再開啟Apache(httpd-ssl.conf)，找到：Listen 443 替換成：Listen 4433；找到：和 ServerName localhost:443 替換成：和 ServerName localhost:4433；儲存。（本人配置檔案中未找到ServerName localhost:443，而是ServerName www.example.com:443，總之相應的改掉埠就可以。）
4. 關閉XAMPP，重新開啟，再啟動Apache就不會有問題了。
