linux - Docker 安装在 Linux 中失败并出现错误 [Errno 14] HTTPS 错误 404 - 未找到

Question

我正在尝试在 linux [Redhat] box 中安装 docker。但它因以下错误而失败。

Loaded plugins: product-id, search-disabled-repos, subscription-manager, susemanagerplugin, yumnotify
This system is not registered with an entitlement server. You can use subscription-manager to register.
 https://yum.dockerproject.org/repo/main/centos/7/repodata/repomd.xml: [Errno 
14] HTTPS Error 404 - Not Found
Trying other mirror.

One of the configured repositories failed (Docker Repository),
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=dockerrepo ...

 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 dockerrepo
    or
        subscription-manager repos --disable=dockerrepo

 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=dockerrepo.skip_if_unavailable=true

    failure: repodata/repomd.xml from dockerrepo: [Errno 256] No more mirrors to try.

我浏览了多篇文章并尝试了不同的选项，但没有解决问题。

我正在使用 RHEL 7。
我通过编辑/etc/yum.repos.d/docker-ce.repo 修复了它。用硬编码 7 替换 $releasever 有效。默认情况下变量 $releasever = 7Server。
例子:
baseurl=https://download.docker.com/linux/centos/7/$basearch/stable
