檔案管理 - file 模組

1. file 模組可以做檔案管理，完整文件可用 ansible-doc 查詢 file 模組文件。

   [deyu1@kvm19  ansible]$ ansible-doc file
   

2. file 模組檔案管理範例：
   1. 修改檔案的屬性

      -m file -a "dest=~/foo mode=600"
      

   2. 修改檔案的擁有者、所屬群組

      -m file -a "dest=~/foo owner=user1 group=shgrp"
      

   3. 建立目錄，並設定目錄屬性、擁有者、所屬群組。

      -m file -a "dest=~/c mode=755 owner=user1 group=shgrp state=directory"
      

   4. 刪除目錄

      -m file -a "dest=~/c state=absent"
      

3. 使用 file 模組修改檔案 /home/deyu1/adhoc.txt 的屬性成 660，擁有者及群組皆為 deyu1。

   [deyu1@kvm19 ansible]$ ansible prod -m file -a "dest=/home/deyu1/adhoc.txt \
   mode=660 owner=deyu1 group=deyu1"

       "ansible_facts": {
           "discovered_interpreter_python": "/usr/libexec/platform-python"
       },
       "changed": true,
       "gid": 1000,
       "group": "deyu1",
       "mode": "0660",
       "owner": "deyu1",
       "path": "/home/deyu1/adhoc.txt",
       "secontext": "unconfined_u:object_r:user_home_t:s0",
       "size": 21,
       "state": "file",
       "uid": 1000
   }
   kvm14 | CHANGED => {
       "ansible_facts": {
           "discovered_interpreter_python": "/usr/libexec/platform-python"
       },
       "changed": true,
       "gid": 1000,
       "group": "deyu1",
       "mode": "0660",
       "owner": "deyu1",
       "path": "/home/deyu1/adhoc.txt",
       "secontext": "unconfined_u:object_r:user_home_t:s0",
       "size": 21,
       "state": "file",
       "uid": 1000
   }
   

4. 使用 shell 模組查看 prod 群組裡所有主機，adhoc.txt 的屬性已改成 660，擁有者及群組也都改成 deyu1 了。

   [deyu1@kvm19 ansible]$ ansible prod -m shell -a "ls -l /home/deyu1/adhoc.txt"
