rabbitmq推荐的安装方式：

1、首先让我们的系统信任我们要增加的源：

wget -O - 'https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc' | sudo apt-key add -

2、增加erlang和rabbitmq源：

echo "deb https://dl.bintray.com/rabbitmq/debian bionic main erlang" | sudo tee /etc/apt/sources.list.d/bintray.rabbitmq.list

3、源更新过后要运行：

apt-get update

4、卸载erlang rabbitmq（如果之前安装过的话）：

apt-get remove rabbitmq
apt-get purge erlang
apt-get autoremove

5、重新安装erlang 和 rabbitmq：

apt-get install erlang
apt-get install rabbitmq-server

6、再检查rabbitmq的版本：
已经是最新版本的3.7.8
