无法将 Puma 作为服务启动

Question

When I lanch the command /home/centos/.rvm/rubies/ruby-3.0.0/bin/bundle exec puma -C /home/centos/app/config/puma.rb in the app folder I get no error:

[145103] Puma starting in cluster mode...
[145103] * Puma version: 5.2.1 (ruby 3.0.0-p0) ("Fettisdagsbulle")
[145103] *  Min threads: 1
[145103] *  Max threads: 5
[145103] *  Environment: production

[145103] *     Restarts: (✔) hot (✔) phased
[145103] * Listening on unix:///home/centos/app/tmp/sockets/puma.sock

But when I try to start Puma as service service puma start && service puma status I get:

● puma.service - Puma HTTP Server
   Loaded: loaded (/etc/systemd/system/puma.service; enabled; vendor preset: disabled)
   Active: activating (auto-restart) (Result: exit-code) since Mon 2021-02-15 17:37:24 UTC; 938ms ago

Feb 15 17:37:24 centos-s systemd[1]: puma.service: Failed with result 'exit-code'.

I don't understand why?

Problem solved, just a too much parenthesis in the config/puma.rb
