使用文件模块创建一个目录，并使用命令“ansible-doc file”获取文件模块的详细信息

这里有一个选项“state”解释:

If directory, all immediate subdirectories will be created if they do not exist, since 1.7 they will be created with the supplied permissions. If file, the file will NOT be created if it does not exist, see the [copy] or [template] module if you want that behavior. If link, the symbolic link will be created or changed. Use hard for hardlinks. If absent, directories will be recursively deleted, and files or symlinks will be unlinked. Note that file will not fail if the path does not exist as the state did not change. If touch (new in 1.4), an empty file will be created if the path does not exist, while an existing file or directory will receive updated file access and modification times (similar to the way touch works from the command line).

可以直接执行该命令，使用ansible直接创建

ansible -v targethostname -m shell -a "mkdir /srv/www" -u targetuser

OR

ansible -v targethostname -m file -a "path=/srv/www state=directory" -u targetuser

我们有模块可以在ansible中创建目录，文件

例子

- name: Creates directory
  file:
    path: /src/www
    state: directory

在这种情况下，您需要使用文件模块。下面的剧本，你可以使用你的参考。

    ---
     - hosts: <Your target host group>
       name: play1
       tasks: 
        - name: Create Directory
          files:
           path=/srv/www/
           owner=<Intended User>
           mode=<Intended permission, e.g.: 0750>
           state=directory 

你可以用以下方法之一来做这件事:

例1:如果父目录已经存在:

- name: Create a new directory www at given path 
  ansible.builtin.file:
    path: /srv/www/
    state: directory
    mode: '0755'

例2:父目录不存在:

- name: Create a new directory www at given path recursively
  ansible.builtin.file:
    path: /srv/www/
    state: directory
    mode: '0755'
    recurse: yes

在示例2中，如果两个目录都不存在，它将递归地创建它们。

另外，在很多情况下，您需要创建多个目录，因此使用循环而不是为每个目录创建单独的任务是一个好主意。

- name: creates multiple directories in one task
  file:
    path: "{{ item }}"
    state: directory
  loop:
    - /srv/www
    - /dir/foo
    - /dir/bar
