我在 Ubuntu 機器上安裝了 Apache2。起初，它工作得很好，因為我在課程中多次開始和重新啟動。但現在突然當我嘗試重新啟動時，它給了我這個錯誤訊息：
[....] Restarting apache2 (via systemctl): apache2.serviceJob
for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.
檢查後，systemctl status apache2.service它給了我以下訊息：
● apache2.service - LSB: Apache2 web server

我無法弄清楚是什麼可能導致此錯誤。
答案1
正如訊息Cannot load /usr/lib/apache2/modules/libphp7.0.so into server所暗示的那樣，您的 mod_php 可能已損壞/遺失/意外刪除/等等。嘗試執行sudo apt-get install --reinstall libapache2-mod-php7.0重新安裝軟體包，然後再次重新啟動 apache。
