批量安装软件包

[root@manager ~]# cat f7.yml
---
- hosts: all
  remote_user: root
  tasks:
    - name: Installed Pkg
      yum: name={{ item }} state=present
      with_items:
        - wget
        - tree
        - lrzsz

标准循环使用场景-批量创建用户

[root@manager ~]# cat f7.yml
- hosts: all
  remote_user: root
  tasks:
    - name: Add Users
      user: name={{ item.name }} groups={{ item.groups }} state=present
      with_items:
        - { name: 'testuser1', groups: 'bin' }
        - { name: 'testuser2', groups: 'root' }

标准循环使用场景-拷贝多个目录

[root@manager ~]# cat f7.yml
- hosts: all
  remote_user: root
  tasks:
    - name: Configure Rsync Server
      copy: src={{ item.src }} dest=/etc/{{ item.dest }} mode={{ item.mode }}
      with_items:
        - {src: "rsyncd.conf", dest: "rsyncd.conf", mode: "0644"}
        - {src: "rsync.passwd", dest: "rsync.passwd", mode: "0600"}
