ansible密码认证，为新系统添加key

1、在文件/etc/ansible/hosts中定义变量

示例：

[HOSTGROUP]

web[1:9].fun.com

[HOSTGROUP:vars]

ansible_ssh_user="fun"

ansible_ssh_pass="funpass"

2、添加认证key

ansible HOSTGROUP -m authorized-key -a "user=fun key={{ lookup('file', '~/.ssh/id_rsa.pub') }}"

错误：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.

1、安装sshpass模块：sudo yum install sshpass -y

2、修改配置文件：/etc/ansible/ansible.cfg

host_key_checking = False

ask_pass = True
