一、检测安装系统版本

查看Linux版本命令如下：

1、查看Linux内核

cat /proc/version
uname -a

2、查看Linux系统版本的命令

lsb_release -a          #即可列出所有版本信息
cat /etc/redhat-release #这种方法只适合Redhat系的Linux
cat /etc/issue          #此命令也适用于所有的Linux发行版

二、下载对应系统版本的软件包

RabbitMQ官网

Erlang and Elixir Packages Download - Erlang Solutions (erlang-solutions.com)

三、安装步骤.

当前系统为 Centos7。下载软件版本如下：

rabbitmq-server-3.9.13-1.el7.noarch.rpm，esl-erlang_23.3.4.5-1_centos_7_amd64.rpm

1、rabbitmq是使用Erlang开发，所以先安装Erlang

注意RabbitMQ与Erlang之间的版本对应关系

# 先安装依赖，否则可能报错
yum install -y libtool
yum install -y *unixODBC*
rpm -Uvh esl-erlang_23.3.4.5-1_centos_7_amd64.rpm
yum install -y erlang

安装完，使用 erl -version

[root@VM-16-2-centos rabbitmq]# erl -version
Erlang (SMP,ASYNC_THREADS,HIPE) (BEAM) emulator version 11.2.2.4

2、安装RabbitMq

rpm -Uvh rabbitmq-server-3.9.13-1.el7.noarch.rpm
yum install -y rabbitmq-server

执行完上面的命令，如果无错误，说明安装成功。

3、启动RabbitMq

systemctl start rabbitmq-server

查看启动状态：

systemctl status  rabbitmq-server
