在剧本中设置循环信息
vim test04.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‘ }

vim test05.yml

• hosts: all
  remote_user: root
  tasks:
  • name: Installed Pkg
    yum: name={{ item }} state=present
    with_items:
    - wget
    - tree
    - lrzsz

实践配置：
[root@m01 ansible_playbook]# cat test_循环功能.yaml

• hosts: 172.16.1.7
  tasks:

  - name: 创建多个用户

  user: name={{ item.name }} shell={{ item.shell }} create_home={{ item.create_home }}

  with_items:

  - { name: ‘oldboy01‘, shell: ‘/sbin/nologin‘, create_home: ‘no‘ }

  - { name: ‘oldboy02‘, shell: ‘/sbin/nologin‘, create_home: ‘yes‘ }

  - { name: ‘oldboy03‘, shell: ‘/bin/bash‘, create_home: ‘yes‘ }

  • name: 创建多个用户
    user: name={{ item }} shell=/sbin/nologin create_home=no
    with_items:
    • oldboy04
    • oldboy05
    • oldboy06

扩展说明：单独加载指定主机清单文件
ansible-playbook nfs_auto.yaml -i ./nfs_hosts
-i 指定加载主机清单
在剧本中设置忽略错误
默认playbook会检查命令和模块的返回状态，如遇到错误就中断playbook的执行
可以加入ignore_errors: yes忽略错误
vim test06.yml
- hosts: all
remote_user: root
tasks:
- name: Ignore False
command: /bin/false
ignore_errors: yes
- name: touch new file
file: path=/tmp/oldboy_ignore state=touch

实践配置： 
[root@m01 ansible_playbook]# cat test_忽略错误.yaml 
- hosts: 172.16.1.7
  tasks:
    - name: create user
      shell: useradd oldboy01 -s /sbin/nologin -M
      ignore_errors: yes
    - name: create dir
      shell: mkdir /oldboy
      ignore_errors: yes
    - name: create file
      shell: touch /etc/oldboy.txt
