Запуск Ruby на Rails в качестве systemd

OS: Centos 7

Я пытаюсь запустить Snorby как systemd, но скрипты запускаются неправильно

Я могу сделать bundle exec rails server-e development-b 0.0.0.0 в командной строке, находясь в папке Snorby, без каких-либо проблем, но когда я помещаю его в скрипт и выполняю с systemctl, он работает неправильно.

[Service]
WorkingDirectory=/tmp/snorby
Environment=RAILS_ENV=development
ExecStart=/usr/local/rbenv/shims/bundle exec rails server -d -b 0.0.0.0


выход состояния
