Ansible yum：无法正确循环本地文件的项目

问题描述 投票：0回答：3

执行此类任务以安装本地软件包时（ala yum localinstall）：

- name: Install local packages
  yum:
    name="/my/path/{{ item }}"
    state=installed
  with_items: list_of_packages

list_of_packages 在 vars/main.yml 中定义为：

---
list_of_packages:
  - package1.rpm
  - package2.rpm
  ...

Yum 尝试变得聪明，将所有项目放入一个命令中，但最终仅添加第一个包的路径：

REMOTE_MODULE yum name="/my/path/package1.rpm,package2.rpm" state=已安装

显然找不到第二个包裹

我尝试在里面添加路径，例如：

{{ "/my/path/"+item }}
并继续执行相同的操作。

除了复制“list_of_packages”并添加基本路径之外，还有其他方法吗？ （我正在使用的解决方法）

编辑：详细的测试手册（ansible版本1.9.2）：

# cat playbooks/testlocalinstall.yml
---
- hosts: all:!localhost

  vars:

    list_of_packages:
      - oracleasmlib-2.0.4-1.el6.x86_64.rpm
      - oracleasm-support-2.1.8-1.el6.x86_64.rpm


  tasks:

    - name: Install Packages
      yum: name=/software/{{ item }} state=installed
      with_items: list_of_packages

结果：

# ansible-playbook playbooks/testlocalinstall.yml -i inventory/myinv -vvv

添加列表中每个包的路径效果很好

我无法重现此问题：

  • 使用 
    --downloadonly
    yum 选项下载 3 个软件包（link）
  • Ansible 详细模式显示相同的结果 - 只有第一个包具有路径前缀，但安装有效。

请尝试这个：

  1. 检查 Ansible 版本 - 1.9.2 之前的版本（我正在测试的版本）中可能存在错误

  2. Yum 找不到您提供的软件包列表的依赖项 - 确保使用 

    yum --downloadonly
    下载的所有软件包都在列表中。它们应该与目标包一起明确说明。

  3. 作为解决方法，您可以使用模板模块创建本地 yum 存储库，该模块指向同一文件夹

    /my/path/
    。默认情况下应禁用此存储库。仅在 
    yum
    任务期间使用 
    enablerepo
    ( link )

    4. 启用此存储库

这是我的剧本：

为了使用 

with_items
我相信它需要一个 yaml 列表，而不是逗号分隔的列表。

 name: install local packages   
 yum: name="/my/path/{{ item }}" state=installed  
 with_items:
      - package1.rpm
      - package2.rpm
      - package3.rpm

Ansible 文档不建议在包管理模块中使用循环（

with_items
也是循环），包括
yum
:

与 

loop:
一起使用时，每个包将被单独处理，将列表直接传递给 
name
选项会更有效。

对于最初的问题，模块文档包含以下解释：

在 1.9.2 之前的版本中，此模块单独安装和删除提供给 yum 模块的每个包。当文件名或 url 指定的包必须一起安装或删除时，这会导致问题。在 1.9.2 中，这一问题已得到修复，以便将软件包安装在一个 yum 事务中。但是，如果其中一个软件包添加了其他软件包来自的新 yum 存储库（例如 epel-release），则需要在单独的任务中安装该软件包。这模仿了 yum 的命令行行为。
