配置文件
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
