Question

我在Ubuntu Vagrant机器上尝试使用Ansible剧本进行了一些实验。我写了一个名为exampleyum.yml的简单剧本如下：

---
- hosts: local

  tasks:
    - name: Installing packages
      yum: name=httpd state=latest
      sudo: yes

当我跑步时

ansible-playbook -i ~/inventory.ini exampleyum.yml

我收到以下错误：

任务执行期间发生异常。看到满满的回溯，使用-vvv。错误是：ImportError：没有名为yum的模块致命：[localhost]：失败！ =＆GT; {“已更改”：false，“failed”：true， “module_stderr”：“Traceback（最近一次调用最后一次）：\ n文件 \“/ tmp / ansible_qeXrGO / ansible_module_yum.py \”，第25行，\ n import yum \ nImportError：没有名为yum \ n“，”module_stdout“：”“的模块， “msg”：“MODULE FAILURE”}

它会导致一些导入错误和模块故障。我在某处读到Yum是核心模块

因此它应该正常工作，但事实并非如此。任何帮助，将不胜感激。我对Ansible很新。

Answer 1

我在Ubuntu Vagrant机器上运行Ansible。

那么为什么首先使用yum而不是apt模块？

如果由于某种原因仍需要yum模块，请确保托管主机上安装了yum python软件包。

Answer 2

使用包而不是yum模块，如剧本中的How to unify package installation tasks in ansible?所示。

当我阅读并阅读一本基于CentOS / RedHat编写的书时，我遇到了同样的错误。问题本身可以避免如下，但如果继续在Ubuntu上使用YUM，则会导致进一步的问题。
