InfluxDB не удалось запустить как службу

Я пытаюсь настроить InfluxDB для автоматического запуска на машине RHEL7.

если я делаю:

sudo systemctl start influxdb

сервис не

[dadmin@localhost dashboard]$ sudo systemctl start influxdb
[sudo] password for dadmin: 
[dadmin@localhost dashboard]$ sudo systemctl status influxdb

это единичный файл:

# /usr/lib/systemd/system/influxdb.service
# If you modify this, please also make sure to edit init.sh

но если я выполню непосредственно

/usr/bin/influxd -config /dashboard/influxdb.conf

InfluxDB начать плавно.

где я ошибаюсь?
