（一）要求剧本名/etc/ansible/play/play1.yaml，在被控节点实现初始化操作，例如创建一个demo用户，uid是3450，家目录是/tmp/demo，登录shell是/bin/bash，设置用户的密码为demo，要求这个demo用户可以使用sudo提权，并且控制节点可以实现免密登录到主机的demo用户
- name: play1
hosts: all
tasks:
- name: creat user
user:
name: demo
uid: 3450
home: /tmp/demo
shell: /bin/bash
- name: create passwd
shell: 'echo "demo" | passwd --stdin demo'
- name: sudo
shell: 'echo "demo ALL=(ALL) NOPASSWD:ALL >> /etc/sudoers"'
- name: mkdir /tmp/demo/.ssh
file:
path: /tmp/demo/.ssh
state: directory
owner: demo
group: demo
mode: '0700'
- name: ssh_nopasswd
copy:
src: /root/.ssh/id_rsa.pub
dest: /tmp/demo/.ssh/authorized_keys
（二）要求剧本名/etc/ansible/play/play2.yaml，在所有的被控节点上执行，要求配置本地YUM仓库，然后实现httpd软件的安装，并且最终在控制节点上使用curl命令访问被控节点主机名的时候，访问node1则输出的是node1内容，访问node2则输出的是node2内容
- name: play02
hosts: all
tasks:
- name: mount /dev/sr0
shell: "mount /dev/sr0 /iso"
ignore_errors: yes ##这个ignore_errors是task指令和模块同级作用：忽略这个play的错误
