How to set pid file location?

[Paxa]

When I run it, it only create file in current folder. How to change it to /var/run/app.pid or any other folder?

According to https://github.com/thuehlinger/daemons/blob/master/lib/daemons/pidfile.rb

Daemons is configurable to store the Pid-Files relative to three different locations:

1. in a directory relative to the directory where the script (the one that is supposed to run as a daemon) resides (:script option for :dir_mode)
2. in a directory given by :dir (:normal option for :dir_mode)
3. in the preconfigured directory /var/run (:system option for :dir_mode)

Nice. Can you give an example how to make in /opt/pids/my-app.pid ?

[sodabrew]

Daemons.daemonize(:dir => '/opt/pids')

[Paxa]

But how to make pidfile name not same with application name?

[thuehlinger]

Daemons.daemonize(:app_name => 'custom_app_name', :dir => '/opt/pids')

[sodabrew]

@Paxa or @thuehlinger I think this question is answered and can be closed.

I still can't make different name for process and pid file.

for example process name my_daemon, and pid_file daemon_process.pid

As I see in source code it use same name for pid and proces name

You can set the sub process name in the sub process itself, like this:

Daemons.run_proc('pid_file_name') do
  # Set the process name
  $0 = 'my_fancy_process'

  # Do whatever as a daemon
end
