Возникла следующая проблема при перезагрузке сервера:
root ~ # systemctl restart httpd Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
Чтобы посмотреть, что же произошло выполнил следующую команду:
root ~ # systemctl -l status httpd.service
