host_vars 无法在 Ansible 中工作

我需要host_vars在我的ansible文件中使用在远程主机上安装一个包，我试图 package从host_vars文件所在的目录中按名称拉取一个变量ansi2，该文件是远程计算机的主机名....

---
 - hosts: all
   become: yes
   ignore_errors: yes
   gather_facts: no
   tasks:

   - name: install vim
     yum: name={{ package }} state=present

目录结构：

[root@ansi1 ansible]# pwd
/etc/ansible
[root@ansi1 ansible]#
[root@ansi1 ansible]# ls -l ansi2/host_vars/
total 4
-rw-r--r-- 1 root root 19 Jun 13 08:15 ansi2
[root@ansi1 ansible]#


[root@ansi1 ansible]# cat ansi2/host_vars/ansi2
---
package: "vim"

错误：

TASK [install vim] *************************************************************
task path: /etc/ansible/service.yml:7
fatal: [ansi2.example.com]: FAILED! => {
    "failed": true,
    "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'package' is undefined\n\nThe error appears to have been in '/etc/ansible/service.yml': line 7, column 6, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n   tasks:\n   - name: install vim\n     ^ here\n"
}
...ignoring

答案1

在您的情况下，我假设目录的顶层应包含如下文件和目录：

/etc
+-- ansible/
    +-- host_vars/
        +-- ansi2.example.com.yml
    +-- service.yml

答案2

您的库存可能存在什么问题，里面有什么？

.yml 文件的名称应与主机文件中的名称相同。

/etc/ansible/ansi2/主机

[webdb]
127.0.0.1 ansible_user=root

/etc/ansible/ansi2/host_vars/webdb.yml

---
some_var: "temp"

/etc/ansible/service.yml

   ---
   - hosts: all
     become: yes
     ignore_errors: yes
     gather_facts: no
     tasks:

   - name: install vim
     yum: name={{ package }} state=present
