安装过程
官网提供了一个shell脚本，如下：

#!/bin/sh
## If sudo is not available on the system,
## uncomment the line below to install it
# apt-get install -y sudo

sudo apt-get update -y

## Install prerequisites
sudo apt-get install curl gnupg -y

## Install RabbitMQ signing key
curl -fsSL https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc | sudo apt-key add -

## Install apt HTTPS transport
sudo apt-get install apt-transport-https

## Add Bintray repositories that provision latest RabbitMQ and Erlang 23.x releases
sudo tee /etc/apt/sources.list.d/bintray.rabbitmq.list <<EOF
deb https://dl.bintray.com/rabbitmq-erlang/debian bionic erlang
deb https://dl.bintray.com/rabbitmq/debian bionic main
EOF

## Update package indices
sudo apt-get update -y

## Install rabbitmq-server and its dependencies
sudo apt-get install rabbitmq-server -y --fix-missing

可以一行一行执行，整个过程很快；
启动过程及常用命令

# 启动 rabbitmq 服务
service rabbitmq-server start

# 关闭 rabbitmq 服务
service rabbitmq-server stop

# 重启 rabbitmq 服务
service rabbitmq-server restart

# 查看 rabbitmq 状态
service rabbitmq-server status
注意，启动rabbitmq之后要启动管理服务插件，否则15672管理页面无法登录

# 启用 rabbitmq_manager
sudo rabbitmq-plugins enable rabbitmq_management

其次，guest用户默认只能在localhost登录，所以我们需要创建一个新的用户：

##设置账号密码
[root@rabbitmq1 ebin]# rabbitmqctl add_user admin 123456
Adding user "admin" ...
[root@rabbitmq1 ebin]# rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/" ...
[root@rabbitmq1 ebin]# rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...

然后就可以进入管理页面了：
