Ansible 无法访问 group_vars

Question

我无法访问我的 group_vars。

我的库存文件所在的当前目录

[ansible@akashd1c inventory]$ pwd
/home/ansible/inventory

在清单中创建了 group_vars 目录

[ansible@akashd1c inventory]$ ls
group_vars  inventory

在 group_vars

中创建了 labservers 文件

[ansible@akashd1c group_vars]$ vi labservers

添加变量内容

[ansible@akashd1c inventory]$ cat group_vars/labservers
opt_dir: /opt

使用 ping 测试 --- 工作正常

[ansible@akashd1c inventory]$ ansible akashd2c.mylabserver.com -i inventory -m ping
 akashd2c.mylabserver.com | SUCCESS => {
"ansible_facts": {
    "discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}

现在运行使用变量 - 获取错误

[ansible@akashd1c inventory]$ ansible akashd2c.mylabserver.com -i inventory -a "ls -l {{opt_dir}}"
akashd2c.mylabserver.com | FAILED | rc=-1 >>
The task includes an option with an undefined variable. The error was: 'opt_dir' is undefined

我尝试更改 ansible.cfg 库存日志 - 仍然不起作用。

#inventory = /home/ansible/inventory/inventory

将文件更新为 yml 文件

[ansible@akashd1c group_vars]$ ls
labservers.yml
[ansible@akashd1c group_vars]$ cat labservers.yml 
 ---
 opt_dir: /opt

库存

 [ansible@akashd1c inventory]$ cat inventory 
 akashd2c ansible_host=akashd2c.mylabserver.com
 [labserver]
 akashd2c.mylabserver.com
 akashd3c.mylabserver.com

您的清单中的组是 labserver，但 group_vars 文件名是 labservers.yml，复数

换一个来匹配

将来，您可以非常轻松地使用 ansible-inventory -i ./inventory --list 来验证 ansible 看到的关于主机及其解析的变量的内容：

$ echo 'opt_dir: /opt' > inventory/group_vars/labservers.yml
$ ansible-inventory -i ./inventory --list
{
    "_meta": {
        "hostvars": {
            "akashd2c": {
                "ansible_host": "akashd2c.mylabserver.com"
            }
        }

$ echo 'opt_dir: /opt' > inventory/group_vars/labserver.yml
$ ansible-inventory -i ./inventory --list
{
    "_meta": {
        "hostvars": {
            "akashd2c": {
                "ansible_host": "akashd2c.mylabserver.com"
            },
            "akashd2c.mylabserver.com": {
                "opt_dir": "/opt"
