ansible-playbook批量修改密码

1. 将服务器ip写到ansible hosts文件中

2. 实现免密登录服务器
    将ansible服务器公钥拷贝到目标服务器用户目录下的.ssh/authorized_keys
    手动连接一次或者自己写脚本

3. 编写playbook
    批量修改多用户密码
    - hosts: test
      gather_facts: false
      tasks:
      - name: change user passwd
        user: name={{ item.name }} password={{ item.chpass | password_hash(‘sha512‘) }}  update_password=always
        with_items:
         - { name: ‘root‘, chpass: ‘123456‘ }
         - { name: ‘liutao‘, chpass: ‘Mlxg2234‘ }

4. 修改单个用户
    - hosts: test
      gather_facts: false
      tasks:
      - name: Change password
        user: name={{ name1 }}  password={{ chpass | password_hash(‘sha512‘) }}  update_password=always
　　　　ansible-playbook play.yml -e "name1=root chpass=123456"
