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。

有关file_module的更多信息，您可以查看官方文档

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).

- file:
    path: /etc/some_directory
    state: directory
    mode: 0755
    owner: someone
    group: somegroup

这也是设置权限，所有者和组的方法。最后三个参数不是必须的。

在本例中，您可以使用"file"模块，其中有许多参数可以传递给新创建的目录，如所有者、组、位置、模式等.....

关于文件模块的详细说明请参考本文档…

https://docs.ansible.com/ansible/latest/modules/file_module.html#file-module

记住这个模块不仅仅是用来创建目录的!!

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

enter code here 
- name: creating directory in ansible
  file:
   path: /src/www
   state: directory
   owner: foo
