无法从/etc/ansible的group_vars文件中加载和获取变量

Question

[admin@ansicontrol newvarsexample]$ ansible --version
ansible 2.9.18
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/admin/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.8/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.8.2 (default, Feb 28 2020, 00:00:00) [GCC 10.0.1 20200216 (Red Hat 10.0.1-0.8)]

Ansible清单文件/etc/Ansible/hosts:

[stack]
192.168.47.130

Ansible Playbookfedoragroupvarfile.yaml:

- hosts: all
  remote_user: admin
  tasks:
    - name: Set OS distribution dependent variables
      include_vars: "os_{{ ansible_facts['distribution'] }}.yaml"
    - debug:
        var: fedcharm

Ansible group_vars文件/etc/Ansible/group_vars/os_fedora.yaml:

fedcharm: "This is Fedora 32 OS variable file"

TASK [Set OS distribution dependent variables] *******************************************************************************
fatal: [192.168.47.130]: FAILED! => {"ansible_facts": {}, "ansible_included_var_files": [], "changed": false, "message": "Could not find or access 'os_Fedora.yaml'\nSearched in:\n\t/home/admin/practiceansible/newvarsexample/vars/os_Fedora.yaml\n\t/home/admin/practiceansible/newvarsexample/os_Fedora.yaml\n\t/home/admin/practiceansible/newvarsexample/vars/os_Fedora.yaml\n\t/home/admin/practiceansible/newvarsexample/os_Fedora.yaml on the Ansible Controller.\nIf you are using a module and expect the file to exist on the remote, see the remote_src option"}

如果不使用-I/path/to/inventory.yaml指定目录，则“默认位置”是ansible查找目录的位置，但是使用include_vars包含的文件不是目录，只包含裸变量。
如果使用相对路径的include_vars，ansible将在相对于playbook/role的位置查找文件（请参阅文档）。
也可以在include_vars中指定绝对路径。例如。/etc/ansible/variables.yaml（文件必须存在）。

但实际上，我不认为那是你想要的。如果变量位于/etc/ansible/group_vars中，如果目录结构正确，则默认情况下将不加载include_vars。检查一下文件。

在/etc/ansible/group_vars/stack.yaml:

fedcharm: "This is Fedora 32 OS variable file"

和fedoragroupvarsfile.yaml应包含以下内容：

- hosts: all
  remote_user: admin
  tasks:
    - debug:
        var: fedcharm

然后像以前一样运行你的剧本。如果所有操作都正确，ansible将从/etc/ansible/group_vars/stack.yaml中加载目录中组堆栈的变量，并显示正确的消息。
