<pre>



ansible在使用配置文件时按照以下顺序优先配置：

export ANSIBLE_CONFIG

./ansible.cfg

~/.ansible.cfg

/etc/ansible/ansible.cfg

如果以上顺序没有找到配置文件ansible会自动使用默认配置

可以去github上把默认配置拿下来：

https://raw.githubusercontent.com/ansible/ansible/devel/examples/ansible.cfg
# To generate an example config file (a "disabled" one with all default settings, commented out):
#               $ ansible-config init --disabled > ansible.cfg

# Also you can now have a more complete file by including existing plugins:
# ansible-config init --disabled -t all > ansible.cfg

把它放到/etc/ansible/目录
