在RHEL 7 Linux服务器上安装Docker时出现的问题

最近我不断地遇到这个问题，最后需要一些帮助，因为我完全被卡住了

我刚刚访问了RHEL EC2 Linux服务器，我只是想安装Docker。这个过程最近非常痛苦。在尝试遵循在线提到的流程时，大量404HTTP未发现错误

根据，您只需运行以下两个命令之一：

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

• sudo amazon linux附加安装docker
• sudo yum安装docker

但是，这两个命令都不起作用，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]#

[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]# 

以下是我尝试过做的事情列表：

第一次尝试（回复：）

第二个答案是，您只需运行以下命令：

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]# 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]#

[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

运行

curl时https://get.docker.com |bash

，这也不起作用

第三次尝试：

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.

 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

任何帮助都将不胜感激。此时似乎几乎不可能安装docker。

运行了以下命令，这就成功了：

yum install -y https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
yum install -y https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm

从internet和internet下载这3个软件包的最新版本

[root@test_hostame docker19.03_rpm]# ll
total 93904
-rw-r--r-- 1 root root 30381608 Jan 20 18:19 containerd.io-1.3.9-3.1.el7.x86_64.rpm
-rw-r--r-- 1 root root 25519432 Jan 20 18:19 docker-ce-19.03.14-3.el7.x86_64.rpm
-rw-r--r-- 1 root root 40247412 Jan 20 18:19 docker-ce-cli-19.03.14-3.el7.x86_64.rpm

在仅存在这3个包的文件夹中运行命令

yum localinstall *rpm

这肯定会奏效的。如果没有，请分享您的错误。
