centOS stream 9 安装rabbitMQ4.2
环境：centOS stream 9
安装前提条件：
1、Installing the package using the *.rabbitmq.com dnf/yum repositories (this option is highly recommended)：强烈推荐这种方式
2、Downloading the package and installing it with rpm. This option will require manual installation of all package dependencies and makes upgrades more difficult.（手动安装，比较困难）
安装前，必须先安装erlang;
