在执行ansible-playbook example.yml时候，总是提示paramiko: The authenticity of host 'XXXX' can't be established.

paramiko: The authenticity of host '192.168.1.1' can't be established.
The ssh-rsa key fingerprint is eff0743134e86397485685c5c9d84b8e.
Are you sure you want to continue connecting (yes/no)?

比较奇怪的是，其实这台主机是可以ssh登录的，并且已经ssh可以正常登录（并没有提示需要确认主机key）：检查可以看到/etc/ssh/ssh_config配置了

StrictHostKeyChecking no
UserKnownHostsFile /dev/null

所以ssh HOST时候不会报错（即不校验host key）。

但是paramiko是不使用/etc/ssh_config配置，导致ansible还是要校验host key。

参考 Host Key Checking，我们可以在 /etc/ansible/ansible.cfg或~/.ansible.cfg添加

[defaults]
host_key_checking = False

或

export ANSIBLE_HOST_KEY_CHECKING=False
