知识点：ping模块，用于确认和对象机器之间是否能够ping通，正常情况会返回pong
知识点：setup模块，用于收集对象机器的基本设定信息。
ping使用实例
[root@host31 ansible]# ansible host32 -m pinghost32 | SUCCESS => { "changed": false, "ping": "pong"}[root@host31 ansible]#

setup使用实例
不用option的情况会输出所有相关的对象机器的facts
[root@host31 ~]# ansible host32 -m setuphost32 | SUCCESS => { "ansible_facts": { "ansible_all_ipv4_addresses": [ "192.168.122.1", "172.16.96.1", "172.16.96.0", "192.168.32.32" ],

setup常用Option：filter
比如收集对象机器的环境变量信息
