【问题描述】：
我最近越来越多地遇到这个问题，终于需要一些帮助，因为我完全卡住了。
我刚刚获得了 RHEL EC2 Linux 服务器的访问权限，我只是想安装 Docker。这个过程最近非常痛苦。尝试遵循在线提到的流程时出现大量 404 HTTP Not Found 错误
根据https://docs.aws.amazon.com/AmazonECS/latest/developerguide/docker-basics.html，您可以简单地运行以下两个命令之一：
- sudo amazon-linux-extras 安装 docker
- sudo yum install docker
但是，这些命令都不起作用，如下面的输出所示：
[root@d8de679d27f2454 myuser]# sudo amazon-linux-extras install docker
sudo: amazon-linux-extras: command not found
[root@d8de679d27f2454 myuser]# yum install docker
Loaded plugins: amazon-id, search-disabled-repos
No package docker available.
Error: Nothing to do
[root@d8de679d27f2454 myuser]#
这是我尝试做的事情的清单：
第一次尝试（RE：How to install docker on Amazon Linux2）
提出的第二个答案是您可以运行以下命令：
sudo yum update -y
sudo yum -y install docker
但是，这也不起作用，如下面的输出所示：
[root@d8de679d27f2454 myuser]# yum update -y
Loaded plugins: amazon-id, search-disabled-repos
No packages marked for update
[root@d8de679d27f2454 myuser]# yum -y install docker
Loaded plugins: amazon-id, search-disabled-repos
No package docker available.
Error: Nothing to do
[root@d8de679d27f2454 myuser]#
第二次尝试：通过get.docker.com安装
在运行curl https://get.docker.com | bash 时，这也不起作用
第三次尝试：https://computingforgeeks.com/install-docker-ce-on-rhel-7-linux/
本文的一部分建议运行以下两个命令：
sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
但是，这也不起作用：
# yum install -y yum-utils device-mapper-persistent-data lvm2
Loaded plugins: amazon-id, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.

To address this issue please refer to the below knowledge base article
https://access.redhat.com/articles/1320623
If above article doesn't help to resolve this issue please open a ticket with Red Hat Support.
One of the configured repositories failed (Docker CE Stable - x86_64),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=docker-ce-stable ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable docker-ce-stable
or
subscription-manager repos --disable=docker-ce-stable
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=docker-ce-stable.skip_if_unavailable=true
failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try.

这是我的cat /etc/os-release 命令的输出

任何帮助将不胜感激。此时安装 docker 似乎几乎是不可能的。
