Debian上的RabbitMQ从3.8.2升级到3.8.6 --如何安装最新版本？

Question

我正在尝试将RabbitMQ从3.8.2版本升级到最新版本3.8.6，该集群是通过Azure中的Bitnami创建的两个Linux (运行Debian9Sch)。根据RabbitMQ文档，我可以通过停止其中一个节点，在其上安装最新版本，重新启动该节点，然后在另一个节点上执行相同的操作来进行滚动升级。这些机器使用Erlang 22运行，RabbitMQ状态与3.8.6版本兼容：

bitnami@AI-RabbitMQ-02:~$  erl -eval 'erlang:display(erlang:system_info(otp_release)), halt().'  -noshell
"22"

在使用PackageCloud安装的文档步骤之后，我成功地安装了存储库，输出如下：

bitnami@AI-RabbitMQ-02:~$ sudo rabbitmqctl stop_app

bitnami@AI-RabbitMQ-02:~$ curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.deb.sh | sudo bash                                                                                                          abbitmq/rabbitmq-server/script.deb.sh | sudo bash

然后，我尝试下一步，安装RabbitMQ，出现以下错误：

我也尝试过使用Bintray选项进行安装，但是没有效果。我也尝试过用dpkg -i手动安装，但我不确定如何处理包依赖关系，因为兔子页面上的链接是用于该步骤的在任何地方都不会。任何对升级的帮助都将不胜感激。非常感谢!

Answer 1

我有Erlang23和RabbitMQ Server3.8.2(它们不完全兼容，所以我决定将RabbitMQ服务器升级到3.8.9，因为我在运行应用程序时遇到了一些问题)

在Ubuntu20.04的AWS EC2实例上，我有一个带有一个节点的集群(未按照RabbitMQ的建议通过插件进行正确的配置--我计划稍后再这样做)。

我所做的和它对我的作用(在sudo或根sudo su下执行的命令)：

1. 对于shutdown来说，重要的不仅仅是stop_app，因为Erlang也需要停止，而stop_app只停止RabbitMQ服务器离开Erlang，这可能会在启动新版本的RabbitMQ服务器时给您带来错误--因为端口25672正在忙着处理另一个应用程序： rabbitmqctl shutdown
2. 将rabbitmq文件从旧版本(由于某种奇怪的原因而不是运行的3.8.2 )改为新的版本--在我的例子中是3.8.9： vim /etc/apt/preferences.d/rabbitmq
3. 重新检查是否安装了依赖项： apt-get -y install socat logrotate init-system-helpers adduser
4. 如果您没有wget，请安装wget： apt-get -y install wget
5. 下载最新的服务器安装文件.deb包： wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.9/rabbitmq-server_3.8.9-1_all.deb
6. 安装： dpkg -i rabbitmq-server_3.8.9-1_all.deb
7. 删除发行版： rm rabbitmq-server_3.8.9-1_all.deb
8. 检查服务器是否停止(可能是冗余命令)： service rabbitmq-server stop
9. 重新启动服务器： service rabbitmq-server restart
10. 检查服务器状态： rabbitmq-server status
11. 如果它给您一个错误引导失败。分发端口25672正在由另一个节点使用，请检查谁使用该端口--可能是Erlang使用该端口： lsof -i :25672
12. 启动RabbitMQ应用程序： rabbitmqctl start_app
13. 检查节点状态： rabbitmqctl status

您应该会看到升级的RabbitMQ服务器版本(在我的示例3.8.9中)以及最新的Erlang版本(在我的示例23中)。
