RabbitMQ RPM installation failed on Red Hat Enterprise Linux 7.2 (even with erlang installed)

Question

In the homepage of RabbitMQ it says

1. First install erlang

2. Then install RabbitMQ by

   rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

   yum install rabbitmq-server-3.6.3-1.noarch.rpm

I installed erlang but when install RabbitMQ it failed, the error says

Requires: erlang>=R16B-03

But I have already installed erlang 19.0, what's the problem? Someone in other article suggested RabbitMQ doesn't support erlang 19.0 right now, then what should I do? I have already installed erlang 19.0 and tried installing erlang 18.3 without deleting erlang 19.0, because I don't know how to uninstall erlang :( , it still fails (but $erl shows the version is 18.3).

Answer 1

RabbitMQ will support Erlang 19.0 starting from the version 3.6.4 (currently in RC1).

I suggest to use the zero dependency Erlang/OTP 18.3.4 package here:

https://github.com/rabbitmq/erlang-rpm/releases/tag/v1.3.0

install it in this way:

wget https://github.com/rabbitmq/erlang-rpm/releases/download/v1.3.0/erlang-18.3.4-1.el7.centos.x86_64.rpm 
rpm -i erlang-18.3.4-1.el7.centos.x86_64.rpm

To remove your current erlang installation try using:

sudo yum remove erlang*
