ansible第一次使用模块报错

报错信息：
[root@localhost ansible]# ansible -i /etc/ansible/hosts web-servers -m ping

  "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."

解决办法：
1、如果主机和被控制端第一次通讯，需要先添加指纹信息

ping 192.168.75.129

[root@localhost ansible]# ping 192.128.75.129
PING 192.128.75.129 (192.128.75.129) 56(84) bytes of data.

[root@localhost ansible]# ansible -i /etc/ansible/hosts web-servers -m ping
[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details
192.168.75.129 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}

2、如果多台机器第一次的情况下，可以开启ansible中的 host_key_checking = False

[root@localhost ansible ~]# vim /etc/ansible/ansible.cfg 
host_key_checking = False
