ssh首次链接出现yes/no提示和ansible提示

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：
