修改文件： /etc/ssh/ssh_config
在文件中添加如下信息：StrictHostKeyChecking no
改本机的/etc/ssh/ssh_config文件中的"# StrictHostKeyChecking ask" 为 "StrictHostKeyChecking no"，
如何去除ssh无交互式添加 known_hosts
配置文件/etc/ansible/ansible.cfg的[defaults]中
打开注释
# uncomment this to disable SSH key host checking
host_key_checking = False
ansible自动下发ssh密钥：
