Erlang: how to get multiple releases running at the same time?

Is it possible to have multiple releases created by rebar to run at the same time? I have one server where I'd like to run different releases simultaneously to test them out. The problem is when I do:

rel/myapp_a/bin/myapp_a stop

It manages to stop my VM which is running myapp_b

How do I get them to run as their own entities that do not interfere with each other?

Solution

  • First I would check if the two nodes are connected to each other:

    On one or each of the nodes run

    Eshell V5.7.5  (abort with ^G)
1> nodes().
[]

    and make sure the list is empty or only containing other nodes that are supposed to be connected.

    Check if the nodes can be connected at all by calling netadm:ping/1 and try to connect the nodes. If they can be connected and shouldn't make sure to run them with different cookies.
