systemctl service can't restart on reboot

Question

I have created a service for systemctl which works perfectly but whenever I reboot the server it can't auto-restart itself.

The code for the service is:

[Unit]
Description=Service Description
[Service]
User=ubuntu
Group=ubuntu
WorkingDirectory=project_path
Restart=always
ExecStart=/home/ubuntu/.rvm/gems/ruby-2.6.3/wrappers/bundle exec /usr/share/rvm/rubies/ruby-2.6.3/bin/rake QUEUE=* resque:work

Path for the service is

/lib/systemd/system/worker.service

I have start the service by command systemctl start service_name — Shivashish Singh, Jan 28 '20 at 11:07
But did you enable it via `systemctl enable service_name`? Else it would only be enabled during the current session. — creyD, Jan 28 '20 at 11:08
I'm running the command then I'm getting this error: The unit files have no installation config (WantedBy, RequiredBy, Also, Alias settings in the [Install] section, and DefaultInstance for template units). This means they are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. — Shivashish Singh, Jan 28 '20 at 11:09

The service you created needs to be enabled, not only by starting it, but by letting systemd know, that it exists. That can be done by using the command systemctl enable worker.service.

You might need to add some values to the config for getting the service to run properly, but without enabling the service it can't be triggered after a restart automatically.
