RabbitMQ not loading with latest version of Erlang

I've installed Erlang from source:

otp_src_R16B01.tar.gz

When I run erl at prompt:

[ec2-user@ip-100-XX-40-55 ~]$ erl
Erlang R16B01 (erts-5.10.2) [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.2  (abort with ^G)
1>

When I run sudo rabbitmqctl status the version is R14, not R16:

`status of node 'rabbit@ip-100-XX-40-55' ...
[{pid,1837},
 ...
 {erlang_version,
     "Erlang R14B04 (erts-5.8.5) [source] [64-bit] [rq:1] [async-threads:30]....

How can I run rabbitmq-server with erlang version R16B01?

Make sure, that the right erl is in your path first. Try which erl and you should see, that it finds the R14B04 and that is why Rabbit starts with it. You can try trhee things:

  • uninstall R14B (if you need only current version of Erlang)
  • adjust PATH variable (if you want to keep the old version)
  • use kerl if you want to manage multiple Erlang releases

kerl is really great, because it is able to adjust path for you with simple script. All you need to do is type three commands:

kerl build R16B01 r16b01
kerl install r16b01 /path/to/install/dir/
. /path/to/install/dir/activate

You will have to repeat the last step every time, you start a new terminal or put that command in configuration file.

You can also download packaged version of Erlang from the repository
