Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,pas

通过ansible命令直接ping多台机器的网络状态，提示报错：

 

 192.168.0.103 | UNREACHABLE! => {

    "changed": false, 

    "msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).\r\n", 

    "unreachable": true

}

 

解决方式：单向的ssh验证

ssh-keygen一路回车,主要是用来免密通信的

ssh-copy-id 192.168.0.103 需要输入对应主节的root密码

 

 再次验证，成功：
