从网上找到批量修改Linux服务器root密码的playbook。
使用方法：
1、输入要修改的inventory组
2、按需要，在playbook中输入要修改的IP、新密码，如下：
- hosts: production
remote_user: root
tasks:
- name: change password for root
shell: echo '{{ item.password }}' |passwd --stdin root
when: ansible_eth0.ipv4.address == '{{ item.ip }}'
with_items:
- { ip: "ip1", password: 'password1' }
- { ip: "ip2", password: 'password2' }
- { ip: "ip3", password: 'password3' }
3、执行playbook
ansible-playbook change_passwd.yml
