我自己找到了如何获得正确版本的Erlang的方法， MQ将安装在我的Red Hat版本上。这是我所做的：

I found out on my own how to get the right version of Erlang so that Rabbit MQ will install on my version of Red Hat. Here's what I did:

在 /etc/yum.repos.d 中，我创建了 rabbitmq-erlang.repo 文件，其内容如下：

In /etc/yum.repos.d I created a rabbitmq-erlang.repo file with the following contents:

# In /etc/yum.repos.d/rabbitmq-erlang.repo
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/19/el/7
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1

然后我使用以下命令安装了Rabbit MQ，它能够自动安装我需要的正确版本的Erlang：

Then I installed Rabbit MQ using the following commands, and it was able to automagically install the right version of Erlang I needed:

rpm --import https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
yum install rabbitmq-server-3.7.4-1.el7.noarch.rpm
