Two years ago I was running the following command:
bundle exec puma -C config/puma.rb -b unix:/home/user/site/shared/tmp/sockets/user-puma.sock -d
bundle exec sidekiq -d
But now, after some Ubuntu updates, the -d flag is deprecated and I can't start the Puma and Sidekiq processes to run in background.
I also tried running:
bundle exec puma -C config/puma.rb -b unix:/home/user/site/shared/tmp/sockets/user-puma.sock &
bundle exec sidekiq &
This works only while I'm logged on the SSH, when I close the SSH connection, all processes opened with & are closed.
How can I run Puma, Sidekiq and other processes in background as Daemons?
What works for me is setting up my own systemd service for sidekiq
A well-documented example file is in the sidekiq github repository
Along with this, I'd also recommend using monit to watch background processes... here's a recipe from Lugo Labs that I loosely base my deploys off of
