您需要文件模块。要创建目录，您需要指定选项状态:directory:

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

你可以在https://docs.ansible.com/ansible/latest/collections/ansible/builtin/file_module.html上看到其他选项

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).

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

您甚至可以扩展文件模块，甚至可以通过它设置所有者、组和权限。(参考:Ansible文件文档)

- name: Creates directory
  file:
    path: /src/www
    state: directory
    owner: www-data
    group: www-data
    mode: 0775

甚至，你可以递归地创建目录:

- name: Creates directory
  file:
    path: /src/www
    state: directory
    owner: www-data
    group: www-data
    mode: 0775
    recurse: yes

这样，如果这两个目录不存在，它将创建它们。

这里有一个更简单的方法。

—name:创建dir mkdir -p dir dir/a dir/b

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。
