rabbitmq需要erlang和socat，安装erlang参加博文：
下载：

wget https://mirrors.tuna.tsinghua.edu.cn/erlang-solutions/centos/6/esl-erlang_19.0-1~centos~6_amd64.rpm;
wget http://repo.iotti.biz/CentOS/7/x86_64/socat-1.7.3.2-5.el7.lux.x86_64.rpm;
wget www.rabbitmq.com/releases/rabbitmq-server/v3.6.5/rabbitmq-server-3.6.5-1.noarch.rpm;

rpm安装erlang，socat，rabbitmq：

rpm -ivh esl-erlang_19.0-1~centos~6_amd64.rpm;
rpm -ivh socat-1.7.3.2-5.el7.lux.x86_64.rpm;
rpm -ivh rabbitmq-server-3.6.5-1.noarch.rpm;

但是安装rabbit报错了,报错如下：

warning: rabbitmq-server-3.7.0-1.el6.noarch.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
  erlang >= 19.3 is needed by rabbitmq-server-3.7.0-1.el6.noarch

可能跟版本支持策略有关,这是支持的策略：
