Ansible报错“Using a SSH password instead of a key is not possible because Host Key checking is enable”

执行报错

[root@centos ansible]# ansible host4 -m ping
192.168.13.123 | FAILED! => {
    "msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this.  Please add this host's fingerprint to your known_hosts file to manage this host."
}

hosts文件

[root@centos ansible]# pwd
/etc/ansible
[root@centos ansible]# vim hosts

报错原因

主机第一次进行ssh连接，需要输入一个yes将key字符串加入到 ~/.ssh/known_hosts 文件中

解决方法有两种

• 第一种

###手动进行一次ssh连接即可
[root@centos ansible]# ssh 192.168.13.123
The authenticity of host '192.168.13.123 (192.168.13.123)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes

###执行完之后 就可以执行ansible命令 比较繁琐

• 第二种取消检查key

###ansible的配置文件
[root@centos ansible]# pwd
/etc/ansible
[root@centos ansible]# vim ansible.cfg
host_key_checking = False #设置是否检查SSH主机的密钥，值为True/False。关闭后第一次连接不会提示配置实例

###重新执行 成功
[root@centos ansible]# ansible host4 -m ping
