【README】问题概述 

Errors during downloading metadata for repository 'rabbitmq-erlang':
  - Status code: 404 for https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/23/el/8/repodata/repomd.xml (IP: 3.227.81.238)
Error: Failed to download metadata for repo 'rabbitmq-erlang': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

【1】解决方法 

在/etc/yum.repos.d/目录下编辑 rabbitmq-erlang.repo 

vim rabbitmq-erlang.repo

#In /etc/yum.repos.d/rabbitmq-erlang.repo
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/23/el/8
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1
#yum clean all
#yum makecache

显然 baseurl无法访问，所以需要重新编辑； 

通过在github上查看 rabbimq erlang安装指南 https://github.com/rabbitmq/erlang-rpm ， 

我们把 rabbitmq-erlang.repo 修改如下：

# In /etc/yum.repos.d/rabbitmq_erlang.repo
[rabbitmq-rabbitmq-erlang]
name=rabbitmq-rabbitmq-erlang
baseurl=https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/rpm/el/8/$basearch
repo_gpgcheck=1
enabled=1
gpgkey=https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/gpg.E495BB49CC4BBE5B.key
gpgcheck=1
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
pkg_gpgcheck=1
autorefresh=1
type=rpm-md

[rabbitmq-rabbitmq-erlang-noarch]
name=rabbitmq-rabbitmq-erlang-noarch
baseurl=https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/rpm/el/8/noarch
repo_gpgcheck=1
enabled=1
gpgkey=https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/gpg.E495BB49CC4BBE5B.key
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
gpgcheck=1

[rabbitmq-rabbitmq-erlang-source]
name=rabbitmq-rabbitmq-erlang-source
baseurl=https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/rpm/el/8/SRPMS
repo_gpgcheck=1

gpgkey=https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/gpg.E495BB49CC4BBE5B.key

pkg_gpgcheck=1
autorefresh=1

再次执行 yum  update -y

Errors during downloading metadata for repository 'rabbitmq-rabbitmq-erlang-source':
  - Curl error (7): Couldn't connect to server for https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc [Failed to connect to github.com port 443: Connection refused]

还是报错。 原因是，无法下载文件签名（但通过代理是可以访问的）； 

Couldn't connect to server for https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc

解决方法：

把上述签名key文件下载到本地，然后手动导入到rpm；
