Ubuntu 18.04を使用しています。 「sudo apachectl start」を使用してApache2を再起動できないようです。私はこれを見る
~$ sudo apachectl start
Invoking 'systemctl start apache2'.
Use 'systemctl status apache2' for more info.
Job for apache2.service failed because a timeout was exceeded.
See "systemctl status apache2.service" and "journalctl -xe" for details.
Action 'start' failed.
The Apache error log may have more information.
状態を確認してみる
$ sudo systemctl status apache2.service

しかし、奇妙なことに、「sudo apachectl restart」を実行すると、Apacheが表示され、対話できます。
$ sudo apachectl restart
httpd not running, trying to start
どうなりますか?以下は私のサービス設定ファイルです...
$ sudo cat /lib/systemd/system/apache2.service

理論的には、システムにサービスとして設定されているため、サービスを再起動するために実行可能プログラムを実行しても効果はありません。 "systemctl restart apache2"を使用する必要があります。停止するには、「systemctl stop apache2」と入力して「systemctl start apache2」から始めてください。
