在RHEL7上安装最新版本的Erlang

erlangrhel7
7
我正在尝试将最新的 Erlang 发行版（目前版本为 20.3）安装到 RHEL7（确切地说是 7.5 版本）。Google 告诉我，最新的 Erlang 发行版由Erlang Solutions维护，并在https://packages.erlang-solutions.com/上提供（谢谢！）。您还可以在那里找到添加存储库的说明，以便使用软件包管理器安装 Erlang。

Installation using repository

  1. Adding repository entry

To add Erlang Solutions repository (including our public key for verifying signed package) to your system, call the following commands:

wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
然而，如果我运行命令（我以root身份运行rpm命令），则没有将Erlang Solutions存储库添加到yum repolist中。RHEL7与Centos不同，还是说明有误或者我做错了什么？Erlang Solutions存储库（以及安装说明）也被引用。

我找到了根本原因，并成功从Erlang Solutions存储库安装了Erlang。

根本原因是RHEL中的$releasever与Centos不同，因此不能使用该变量，而必须改为硬编码值。

以下是设置yum的详细步骤，以便可以使用yum从Erlang Solutions和EPEL存储库安装Erlang及其依赖项。

添加以下Erlang Solutions存储库文件：

[root@red ~]# cat /etc/yum.repos.d/erlang-solutions.repo 
[erlang-solutions]
name=CentOS $releasever - $basearch - Erlang Solutions
baseurl=https://packages.erlang-solutions.com/rpm/centos/7/$basearch
enabled=1
gpgcheck=1
gpgkey=https://packages.erlang-solutions.com/rpm/erlang_solutions.asc
[root@red ~]#
注意，baseurl必须更改为 
https://packages.erlang-solutions.com/rpm/centos/$releasever/$basearch

至

https://packages.erlang-solutions.com/rpm/centos/7/$basearch

同时为 Erlang 所需的依赖项添加 EPEL 存储库（wxBase、wxGTK 和 wxGTK-gl）：

[root@red ~]# rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

现在Repolist的样子是这样的：

[root@red ~]# yum repolist
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
repo id                                    repo name                                                      status

[root@red ~]#

Erlang软件包现已发布！

[root@red ~]# yum info erlang

最后你可以使用 yum -y install erlang 安装 Erlang。
从几个不同的存储库中安装了以下包：
