在 RHEL 7 Linux 服务器上安装 Docker 的问题

Question

我最近越来越多地遇到这个问题，最后需要一些帮助，因为我完全陷入困境。

我刚刚访问了 RHEL EC2 Linux 服务器，并且只是尝试安装 Docker。这个过程最近非常痛苦。尝试遵循网上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，您只需运行以下两个命令之一即可：

• sudo amazon-linux-extras 安装 docker
• sudo yum 安装 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列表：

第一次尝试（回复：如何在 Amazon Linux2 上安装 docker）

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

运行时

curl https://get.docker.com | bash

，这也不起作用

第三次尝试：https://computingforgeeks.com/install-docker-ce-on-rhel-7-linux/

本文的部分内容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

任何帮助将不胜感激。此时安装 docker 似乎几乎是不可能的。

Answer 1

运行以下命令，这有效：

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

Answer 2

从互联网下载这 3 个软件包的最新版本并

[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 一定会成功的。如果没有，请分享您的错误。
