ansible facts 获取硬件信息
facts 指的是 ansible_facts 变量，ansible 中使用 setup 模块来获取，包含系统的大部分基础硬件信息，
[root@10_1_162_39 host_vars]# ll
total
-rw-r--r-- root root May : hosts
-rw-r--r-- root root May : test1.yaml
-rw-r--r-- root root May : test.playbook
获取所有变量的命令如下，其中的变量可以在 playbook 入口 yaml 文件中使用，本文在 test.playbook 中引用
[root@10_1_162_39 host_vars]# ansible 10.1.162.18 -m setup -i hosts
