在 ansible.cfg 文件中使用 verbosity 而不是 default_verbosity 如下:

Use verbosity instead of default_verbosity in ansible.cfg file as:

$ cat ansible.cfg
[defaults]
verbosity = 1

verbosity 可以是 0|1|2|3|4 表示 None|-v|-vv|-vvv|-vvvv.

假设，配置文件保存在 特定位置 ansible 调查.

Assuming, the config file is kept under specific locations ansible looks into.

ansible-config list 也可以用来列出所有可用的配置文件设置.

ansible-config list can also be used to list all the available configuration file settings.
