Ansible and FileBeta

使用Ansible通过ssh批量读取和修改Client设备

1. 安装ansible工具

apt-get install ansible

2. 添加需要访问的client信息

ansible配置文件如下

/etc/ansible/ansible.cfg
/etc/ansible/hosts

首先放开ansible.cfg中指定的hosts路径，然后编辑hosts如下：

[client]
x.x.x.x ansible_ssh_user="user_name" ansible_ssh_pass="user_pwd" ansible_ssh_port=

3. 安装sshpass

apt-get install sshpass

4. 执行命令

ansible client -m command -a "ls /root"

5. 用python在IP后添加ssh自动验证

#_*_coding:utf-8_*_

with open('client') as f_input:
    lines=f_input.readlines()
with open('client_aaron', 'w') as f_output:
    for line in lines:
        f_output.write(line.replace(b'\n',b' ansible_ssh_user="usr_name" ansible_ssh_pass="usr_pwd" ansible_ssh_port=22\n'))

f_input.close()
f_output.close()

问题：

1. 首次登陆需要对ssh进行校验，会导致上述命令报错如下

ERROR: 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.
