Linux批量修改主机密码

Posted 2022-05-16 herlly

1、配置hosts

vi /etc/ansible/hosts
[ssh]
192.168.94.1[38:39]

[ssh:vars]
ansible_ssh_pass=Asdf1234

2、编写playbook

vi change_passwd.yaml
- hosts: ssh
  gather_facts: false #省去 facts 采集这一步以提高 playbook 效率
  remote_user: root
  tasks:
  - name: change user passwd
    user: name= item.name  password= item.passwd | password_hash(sha512)   update_password=always
    with_items:
         -  name: root, passwd: Asdf1234 
         -  name: dev, passwd: Asdf1234 
         
 运行
 ansible-playbook change_passwd.yaml

3、根据IP条件去修改主机密码

vi change_passwd.yaml
- hosts: ssh
  remote_user: root
  tasks:
  - name: change password
    shell: echo  item.password  |passwd --stdin root
    when: ansible_ens32.ipv4.address  ==  item.ip 
    with_items:
    -  ip: "192.168.94.138", password: Asdf1234 
    -  ip: "192.168.94.139", password: Asdf1234 
     
运行
ansible-playbook change_passwd.yaml
