Ubuntu
無法重啟 Nginx，“nginx.service 的作業失敗，因為控制程序退出並出現錯誤程式碼。”
我有一個執行 Ubuntu 16.04 的 digitalocean droplet。我使用 Nginx 提供大部分靜態站點，但它突然停止工作。
（正如你可能從這個介紹中了解到的那樣，我在這一切方面都是初學者。）
我試圖重新啟動nginx：
$ sudo service nginx restart Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.systemctl 狀態 nginx.service:

關於它可能是什麼的任何想法？

其他一些程序已經在執行並綁定到埠 80/443，因此 systemd 無法啟動 nginx。這幾乎總是因為該程序是手動啟動的，而不是通過 systemd 啟動的，或者因為您試圖同時啟動兩個不同的 Web 伺服器。
要解決此問題，請在通過 systemd 重新啟動之前自行終止該程序。
sudo killall apache2
