Installing rabbitmq-server on RHEL

问题

When trying to install rabbitmq-server on RHEL:

[ec2-user@ip-172-31-34-1XX ~]$ sudo rpm -i rabbitmq-server-3.3.5-1.noarch.rpm 
  error: Failed dependencies:
     erlang >= R13B-03 is needed by rabbitmq-server-3.3.5-1.noarch

[ec2-user@ip-172-31-34-1XX ~]$ rpm -i rabbitmq-server-3.3.5-1.noarch.rpm 
  error: Failed dependencies:
    erlang >= R13B-03 is needed by rabbitmq-server-3.3.5-1.noarch

I'm unsure why trying to rpm install isn't recognizing my erlang install since running $ erlgives:

[ec2-user@ip-172-31-34-1XX ~]$ which erl
  /usr/local/bin/erl
[ec2-user@ip-172-31-34-1XX ~]$ sudo which erl
  /bin/erl

You will need to ensure that an up-to-date version of Erlang is installed. It is available in the EPEL repository.

You can install it by performing the following:

wget -O /etc/yum.repos.d/epel-erlang.repo http://repos.fedorapeople.org/repos/peter/erlang/epel-erlang.repo

yum install erlang

Following the above setup of Erlang, you can then proceed to install RabbitMQ as follows:

rpm --import http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
  yum install rabbitmq-server-3.3.5-1.noarch.rpm

You can find more info in their setup guide

You need to install erlang via RPM for it to recognise the dependency.

The erlang RPMs are available in the EPEL repository:
