Daemon Mode Not Working In Latest Puma version

[techseria]

I am using puma from last 2 years, recently I have upgraded puma to the latest version and found that daemon mode is not working in the latest version.

Can anyone help me to fix how I can start my application in daemon mode?

See "Deprecations, Removals and Breaking API Changes" at https://github.com/puma/puma/blob/ea81fba045ce191644129cc772608765d1595511/History.md#500--2020-09-17

Daemonization has been removed without replacement. (#2170)

Is there any way through that I can run an application as service mode? As of now, I need to start an application manually after a server reboot.

There are plenty of alternatives for that, some are mentioned in https://github.com/puma/puma/blob/v5.0.4/docs/deployment.md

For more info about Puma and systemd, see https://github.com/puma/puma/blob/v5.0.4/docs/systemd.md

I encourage you to investigate and read up on these tools, the Puma issue tracker isn't really the place to get help with deploying your application (try Stack Overflow etc.) (but you can probably also find information in old issues here).

@techseria Please take a look - this functionality has been extracted into puma-daemon ruby gem. I would love some additional testing if you'd like to use daemonization with 5+ Puma

@kigster Please open a PR to add puma-daemon to the README (deployment and community sections, probably)
