3.yum install erlang
第二步：安装rabbitmq-server
1. 以root用户执行 rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
2. 在/etc/yum.repos.d/ 下创建rabbitmq.repo，添加如下内容
[bintray-rabbitmq-server] name=bintray-rabbitmq-rpm baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.7.x/el/7/ gpgcheck=0 repo_gpgcheck=0 enabled=1
3.yum install rabbitmq-server
4. 1）开启延时队列（非死信队列方式）安装插件： https://www.rabbitmq.com/community-plugins.html 下载rabbitmq_delayed_message_exchange 注意mq版本
