Elixir & Mix all want to make the server as a daemon. There have not been able to find the right way.

In addition, I want to use the erlang reltool.

You can use the --detached option to start the runtime system detached from the system console. It is meant to be used for running daemons and backgrounds processes:

elixir --detached -S mix run

Regarding reltool, you can use exrm although and pass -detached (single -) when configuring the VM arguments. The full argument list for the runtime system can be found here: http://erlang.org/doc/man/erl.html

You should use --erl "-detached" since Elixir 1.9+. Like this:

MIX_ENV=prod elixir --erl "-detached" -S mix run --no-halt

or for Phoenix:

MIX_ENV=prod elixir --erl "-detached" -S mix phx.server
