在 Centos 7 上安裝 Apache

我目前正在嘗試使用以下教程在 Centos 7 上安裝 Apache https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-centos -7。

當我輸入以下命令systemctl start httpd.service啟動 Apache 時，我收到以下錯誤：Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

誰能幫我理解這裡出了什麼問題？還請記住，在伺服器和 linux 方面，我是一個完全的菜鳥，因為我以前從未使用過它們。

我也輸入了以下命令systemctl status httpd.service並得到了以下資訊：

httpd.service - The Apache HTTP Server

如果有任何幫助。

地址已在使用中：AH00072：make_sock：無法綁定到地址

$$ :: $$:80 / 0.0.0.0:80

另一個程序已經在偵聽預設的 HTTP 埠，即埠 80，因此 Apache 無法使用它並且無法啟動。調查以下命令可能有用的內容：

sudo netstat -tnlp | grep :80

或者

ss -tnlp | grep :80
