   [deyu1@kvm19 ansible]$ ansible dev -m setup -a "filter=ansible_default_ipv4"
   kvm11 | SUCCESS => {
       "ansible_facts": {
           "ansible_default_ipv4": {
               "address": "192.168.122.11",
               "alias": "ens3",
               "broadcast": "192.168.122.255",

           "discovered_interpreter_python": "/usr/libexec/platform-python"
       },
       "changed": false
   }
   

3. setup 模組列印 ansible_facts 變數，增加參數 filter=ansible_fqdn，取得其內容。

   [deyu1@kvm19 ansible]$ ansible dev -m setup -a "filter=ansible_fqdn"
   kvm11 | SUCCESS => {
       "ansible_facts": {
           "ansible_fqdn": "kvm11.deyu.wang",
           "discovered_interpreter_python": "/usr/libexec/platform-python"
       },
       "changed": false
   }
   

4. setup 模組列印 ansible_facts 變數，增加參數 filter=ansible_hostname，取得其內容。

   [deyu1@kvm19 ansible]$ ansible dev -m setup -a "filter=ansible_hostname"
   kvm11 | SUCCESS => {
       "ansible_facts": {
           "ansible_hostname": "kvm11",
           "discovered_interpreter_python": "/usr/libexec/platform-python"
