erlang - 在 Red Hat 上安装 RabbitMQ - 错误的 Erlang 版本

Question

我正在尝试按照 https://www.rabbitmq.com/install-rpm.html 中的说明在 Red Hat(Enterprise Linux 7 64 位工作站版本)的评估 VM 上安装 RabbitMQ。 .

我已经从源代码安装了 Erlang 的零依赖版本 https://github.com/rabbitmq/erlang-rpm .安装没有错误，我将其/bin 目录添加到我的路径中。

然后当我尝试使用 yum install rabbitmq-server-3.7.4-1.el7.noarch.rpm 安装 RabbitMQ 时，它失败并告诉我它需要 Erlang 版本 >= 19.3，甚至虽然我当时从源代码安装了最新版本的 Erlang (OTP v20.3)。以下是我尝试安装 RabbitMQ 时的完整输出:

yum can be configured to try to resolve such errors by temporarily enabling
disabled repos and searching for missing dependencies.
To enable this functionality please set 'notify_only=0' in /etc/yum/pluginconf.d/search-disabled-repos.conf

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我自己找到了如何获得正确版本的 Erlang，以便 Rabbit MQ 可以安装在我的 Red Hat 版本上。这是我所做的:

在 /etc/yum.repos.d 中，我创建了一个包含以下内容的 rabbitmq-erlang.repo 文件:

# In /etc/yum.repos.d/rabbitmq-erlang.repo
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/19/el/7
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1

然后我使用以下命令安装了 Rabbit MQ，它能够自动安装我需要的正确版本的 Erlang:

rpm --import https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
yum install rabbitmq-server-3.7.4-1.el7.noarch.rpm
