In the homepage of RabbitMQ it says
erlangThen 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*
