Я получаю сообщение об ошибке после использования `a2ensite MyDomain.com.conf` и запускает` service apache2 reload` [закрыт]

Question 1

Я использую Ubuntu 16.04 LTS, размещенный на Linode.

Я хочу перезагрузить apache2 после того, как я использовал a2ensite MyDamain.com.conf. Но я получаю сообщение об ошибке после того, как я использую a2ensite MyDomain.com.conf, а затем перезагрузите apache2 service apache2 reload

Ошибка после команды

Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.

Когда я использовал system status apache2.service, я получаю эти Результаты:
