所以我執行
systemctl status httpd.service
我得到以下信息：

我發現在信息提示：
：httpd：/etc/httpd/conf/httpd.conf的第353行的語法錯誤：/ etc/httpd/con ...數字的第14行的語法錯誤。
屏幕射擊低於：
353線低於： IncludeOptional conf.d/*.conf
我不知道哪裏是錯誤。
'systemctl status httpd.service'顯示有用的*「**提示：**一些行被省略了，使用'-l'顯示完整。」*這將防止像「/etc/httpd/con ... fVersion>的第16行的語法錯誤被截斷，允許您找到正確的配置文件。 – HBruijn
