第一步也是往往最重要的一步：下载安装包！
Rabbitmq地址：https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.7.5
Erlang地址：https://github.com/rabbitmq/erlang-rpm/releases
特殊说明：
Install Erlang
Before installing RabbitMQ, you must install a supported version of Erlang/OTP. We strongly recommend using a packaged version. There are three commonly used sources for Erlang packages. We recommend using one of them.
- We produce a package stripped down to only provide those components needed to run RabbitMQ. It might be easiest to use if installing Erlang's dependencies is proving difficult.
- Erlang Solutions produces packages that are usually up to date. They produce two sets of packages: ones which are split up and are more convenient to use if you can add a yum repository, and a monolithic package which might be easier if you have to download manually.
- EPEL ("Extra Packages for Enterprise Linux"); part of the Red Hat / Fedora organisation, provides many additional packages, including Erlang. These are the most official packages, and are split into many small packages, but are not always up to date.
将下载好的安装文件（此处注意erlang的rpm包必须从rabbitmq官网提供的github地址下载）
erlang-20.3.4-1.el7.centos.x86_64.rpm和rabbitmq-server-3.7.5-1.el7.noarch.rpm上传到要安装rabbitmq的服务器根目录下：
使用命令 yum install erlang-20.3.4-1.el7.centos.x86_64.rpm进行erlang安装，这样会自行解决依赖问题。（yum源配置方法在本文不再赘述）
Erlang包安装结束后，使用命令 ：
yum install rabbitmq-server-3.7.5-1.el7.noarch.rpm安装rabbitmq包。
