在Red Hat上安装RabbitMQ-错误的Erlang版本 [英] Installing RabbitMQ on Red Hat - wrong Erlang version

问题描述

我试图按照 https://www.rabbitmq.com/install-rpm.html 。

我已经安装了来自 https://github.com/rabbitmq/erlang-rpm 。安装完成没有错误，我将其/ bin目录添加到了我的路径。

I've gone and installed the zero-dependency version of Erlang from the source at https://github.com/rabbitmq/erlang-rpm. That installed without error and I added its /bin directory to my path.

然后我尝试使用 yum安装RabbitMQ时，请安装Rabbitmq-server-3.7.4-1.el7.noarch.rpm ，它失败并告诉我它需要Erlang版本> = 19.3，即使我当时从源头安装了最新版本的Erlang（OTP v20.3）。以下是我尝试安装RabbitMQ时的完整输出：

When I then try to install RabbitMQ using yum install rabbitmq-server-3.7.4-1.el7.noarch.rpm, it fails and tells me it needs Erlang version >= 19.3, even though I installed the latest version of Erlang at the time (OTP v20.3) from the source. Below is the full output from when I try to install RabbitMQ:

$ sudo yum install rabbitmq-server-3.7.4-1.el7.noarch.rpm

**********************************************************************
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

Error: Package: rabbitmq-server-3.7.4-1.el7.noarch (/rabbitmq-server-3.7.4-1.el7.noarch)

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

推荐答案

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

I found out on my own how to get the right version of Erlang so that Rabbit MQ will install on my version of Red Hat. Here's what I did:

在 /etc/yum.repos.d 中，我创建了 rabbitmq-erlang.repo 文件，其内容如下：

In /etc/yum.repos.d I created a rabbitmq-erlang.repo file with the following contents:

# 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：

Then I installed Rabbit MQ using the following commands, and it was able to automagically install the right version of Erlang I needed:

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