尝试添加 epel，然后通过 ansible 在 amazon-linux-2 服务器上进行 yum 更新。我使用的 URL 基于：https ://aws.amazon.com/premiumsupport/knowledge-center/ec2-enable-epel/

我的ansible脚本是：

---
- hosts: all
  remote_user: cloud_user

  tasks:

  - name: 01 add epel
    yum_repository:
      name: epel
      description: EPEL YUM repo
      baseurl: https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
    become: yes

  - name: 02 yum update 
    yum: name=* state=latest
    become: yes

我的错误是在任务 02 上（任务 01 有一个“更改”通知）：

     FAILED! => {"changed": false, "msg": "https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm/repodata/repomd.xml: 
[Errno 14] HTTPS Error 404 - Not Found\nTrying other mirror.\n\n\n One of the configured repositories failed (EPEL YUM repo),\n and yum doesn't have enough cached data to continue. At this point the only\n safe thing yum can do is fail. There are a few ways to work \"fix\" this:\n\n     
1. Contact the upstream for the repository and get them to fix the problem.\n\n     
2. Reconfigure the baseurl/etc. for the repository, to point to a working\n        upstream. This is most often useful if you are using a newer\n        distribution release than is supported by the repository (and the\n        packages for the previous distribution release still work).\n\n     
3. Run the command with the repository temporarily disabled\n            yum --disablerepo=epel ...\n\n     
4. Disable the repository permanently, so yum won't use it by default. Yum\n        
will then just ignore the repository until you permanently enable it\n        again or use --enablerepo for temporary usage:\n\n            
yum-config-manager --disable epel\n        
or\n            
subscription-manager repos --disable=epel\n\n     
5. Configure the failing repository to be skipped, if it is unavailable.\n        Note that yum will try to contact the repo. when it runs most commands,\n        
so will have to try and fail each time (and thus. yum will be be much\n        
slower). If it is a very temporary problem though, this is often a nice\n        
compromise:\n\n            yum-config-manager --save --setopt=epel.skip_if_unavailable=true\n\nfailure: repodata/repomd.xml from epel:
 [Errno 256] No more mirrors to try.\nhttps://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm/repodata/repomd.xml: 
[Errno 14] HTTPS Error 404 - Not Found\n", "rc": 1, "results": []}

任何指导或帮助都会很棒。

https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm不是 yum 存储库，它是一个 yum 包。

正如您在要链接的文档中看到的那样，他们做了一个yum install：

sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

然后他们通过命令启用它yum-config-manager

sudo yum-config-manager --enable epel

另一方面，https://dl.fedoraproject.org/pub/epel/$releasever/$basearch/是一个 yum 存储库 URL。

所以你的第一个任务应该是

- name: 01 add epel
    yum_repository:
      name: epel
      description: EPEL YUM repo
      baseurl: https://dl.fedoraproject.org/pub/epel/$releasever/$basearch/
    become: yes

您的错误实际上显示了它：

https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm/repodata/repomd.xml

看看它是如何尝试获取文件夹repodata和文件的repomd.xml？

现在，如果您浏览https://dl.fedoraproject.org/pub/epel/并查看文件夹下的7示例，然后在任何子文件夹下，您将找到那个确切的repodata文件夹和那个确切的repomd.xml文件。

注意：有关变量的额外信息，$releasever可以$basearch找到：点击此链接

此外，由于您的知识文章指导您使用版本 7（参见 7 中的epel-release-latest-7.noarch.rpm），您可以做的就是将其作为属性传递给您的yum任务。 

- name: 02 yum update 
  yum: 
    name: '*' 
    state: latest
    releasever: 7
  become: yes

注意：我还更改了您的语法，我会说在同一剧本中混合使用 attribute=value 和 YAML 语法是个坏主意。

感谢所有的投入。不确定它是否是 amazon-linux-2 的东西，但我唯一的工作是使用银河角色，代码如下：

  roles:
    - role: geerlingguy.repo-epel
      vars:
        epel_repo_url: "https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm"
        epel_repo_gpg_key_url: "/etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7"
      become: yes

epel-release要安装 EPEL，只需从基础 repo安装软件包就足够了。此外，考虑到建议尽可能不要使用shell或模块，我们可以通过直接更新其配置文件来启用 repo。command所以我建议如下：

- name: Install EPEL repository
  yum:
    name: epel-release
    state: present

- name: Ensure EPEL repo is enabled
  ini_file:
    dest: /etc/yum.repos.d/epel.repo
    section: epel
    option: enabled
    value: '1'

- name: Conduct yum update 
  yum: 
    name: * 
    state: latest
    become: True
    update_cache: True
