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).

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*

    Thanks for your answer. You must be an expert on 'erlang' because you know the zero dependency version. Unfortunately I didn't know that version, so in fact I installed 'erlang' from source which was rather a struggle. Anyway, your commands work! (I still had to 'yum install socat' which is needed by 'RabbitMQ') Thank you very much! – shintaroid Jul 29 '16 at 07:47
