一、官方脚本

直接使用apt安装的rabbitmq版本较低，甚至可能无法使用死信队列等插件。首先提供一个 官方 的安装脚本：

#!/usr/bin/sh
sudo apt-get install curl gnupg apt-transport-https -y
## Team RabbitMQ's main signing key
curl -1sLf "https://keys.openpgp.org/vks/v1/by-fingerprint/0A9AF2115F4687BD29803A206B73A36E6026DFCA" | sudo gpg --dearmor | sudo tee /usr/share/keyrings/com.rabbitmq.team.gpg > /dev/null
## Cloudsmith: modern Erlang repository
curl -1sLf https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/gpg.E495BB49CC4BBE5B.key | sudo gpg --dearmor | sudo tee /usr/share/keyrings/io.cloudsmith.rabbitmq.E495BB49CC4BBE5B.gpg > /dev/null
## Cloudsmith: RabbitMQ repository
curl -1sLf https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/gpg.9F4587F226208342.key | sudo gpg --dearmor | sudo tee /usr/share/keyrings/io.cloudsmith.rabbitmq.9F4587F226208342.gpg > /dev/null
## Add apt repositories maintained by Team RabbitMQ
## 用编辑器打开/etc/apt/sources.list.d/rabbitmq.list 添加下面的源也可以。
sudo tee /etc/apt/sources.list.d/rabbitmq.list <<EOF
## Provides modern Erlang/OTP releases
##
deb [signed-by=/usr/share/keyrings/io.cloudsmith.rabbitmq.E495BB49CC4BBE5B.gpg] https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/deb/ubuntu bionic main
deb-src [signed-by=/usr/share/keyrings/io.cloudsmith.rabbitmq.E495BB49CC4BBE5B.gpg] https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/deb/ubuntu bionic main
## Provides RabbitMQ
##
deb [signed-by=/usr/share/keyrings/io.cloudsmith.rabbitmq.9F4587F226208342.gpg] https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/deb/ubuntu bionic main
deb-src [signed-by=/usr/share/keyrings/io.cloudsmith.rabbitmq.9F4587F226208342.gpg] https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/deb/ubuntu bionic main
EOF
## Update package indices
sudo apt-get update -y
## Install Erlang packages
sudo apt-get install -y erlang-base \erlang-asn1 erlang-crypto erlang-eldap erlang-ftp erlang-inets \erlang-mnesia erlang-os-mon erlang-parsetools erlang-public-key \erlang-runtime-tools erlang-snmp erlang-ssl \erlang-syntax-tools erlang-tftp erlang-tools erlang-xmerl
## Install rabbitmq-server and its dependencies
sudo apt-get install rabbitmq-server -y --fix-missing

但是这个办法对我这里的情况不奏效。解决方法往下看。

二、彻底卸载

## 删除rabbitmq：
sudo apt-get remove rabbitmq-server
## 然后查看依赖
dpkg --list|grep rabbitmq
## 如果有残留 
sudo apt autoremove --purge xxxxx## 删除erlang：
## 同上，命令行先执行
sudo apt-get remove erlang
## 然后查看依赖
dpkg --list|grep erlang
## 挨个删除
sudo apt-get remove xxxxx
## 如果有残留 
sudo apt autoremove --purge xxxxx

三、重新安装

1.安装高版本Erlang

下载 Erlang Solution 仓库的 GPG 密钥：

wget -O- https://packages.erlang-solutions.com/ubuntu/erlang_solutions.asc | sudo apt-key add -

echo "deb https://packages.erlang-solutions.com/ubuntu bionic contrib" | sudo tee /etc/apt/sources.list.d/erlang-solution.list

更新本地包缓存：

sudo apt-get update

重新安装：

sudo apt install erlang

---

2.安装RabbitMQ

将下行添加到你的 /etc/apt/sources.list 文件中：

deb http://www.rabbitmq.com/debian/ 18.04 main

（可选操作）：

wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
sudo apt-key add rabbitmq-signing-key-public.asc

更新：

sudo apt-get update

安装：

sudo apt-get install rabbitmq-server
