我的本地 XAMPP 堆疊在我的 Macbook Pro 上運行了數週（OS X Yosemite 10.10.3、XAMPP 5.5.24）。然後，我花了一些時間嘗試安裝一個庫，但不知何故搞砸了 XAMPP 的安裝。現在 Apache 根本不再啟動了。這就是我嘗試過的。
啟動阿帕契
$ sudo /Applications/XAMPP/xamppfiles/xampp startapache
XAMPP: Starting Apache...fail.
XAMPP: Another web server is already running.
$ sudo /Applications/XAMPP/xamppfiles/xampp stopapache
XAMPP: Stopping Apache...not running.
所以我嘗試查找哪個網頁伺服器已經在運行。
殭屍阿帕契
$ sudo lsof | grep AMP | grep apache
$ ps -x | grep apache
7980 ttys000 0:00.00 grep apache
$ ps -x | grep AMP
7990 ttys000 0:00.00 grep AMP
所以我沒有看到任何網頁伺服器正在運行。
Skype
我關閉 Skype。還是同樣的問題。
連接埠 80 上的其他偵聽器
我按照 mnfc 的回答中的建議檢查了連接埠 80 上的其他偵聽器。

殺死連接埠 80 上的其他偵聽器
我想終止現有的 httpd 進程。我首先關閉了所有其他應用程序，包括 Firefox。當我嘗試使用sudo killall httpd或殺死它們時sudo kill 1227，它們不會消失。我仍然無法啟動我的 Apache 伺服器。
全新安裝
我完全卸載了XAMPP，刪除了目錄，並從安裝包中重新安裝了XAMPP。我重新啟動了我的 Macbook。還是同樣的問題。
答案1
經過幾個月的嘗試，我終於成功了。我找到了解決方案這裡：停用 OSX 內建的 Apache 伺服器。
sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist
答案2
你應該檢查 TCP 套接字上綁定到連接埠 80 的其他進程。
netstat -atp tcp | grep -i "listen"
Achive Internet connections (including servers)
Proto Recv-Q Send-Q Local Address Foreign Address (state)
tcp4 0 0 localhost.25035 *.* LISTEN
sudo lsof -i -P | grep -i "listen"
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
GitHub 850 grgarside 6u IPv4 0x23c345381d089301 0t0 TCP localhost:25035 (LISTEN)
答案3
對於任何正在尋找在 Xamps 上啟動任何伺服器的答案的人（已經對此進行了太長時間的挖掘）。
透過終端進行操作：我發現這個連結肯定有幫助：

mysql-sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start
阿帕契-sudo /Applications/XAMPP/xamppfiles/bin/ftpdctl start
希望有幫助。
