標準loops 循環：下面是官方給的參考，參考鏈接 http://docs.ansible.com/ansible/latest/playbooks_loops.html#standard-loops

- name: add several users

user:

name: "{{ item }}"

state: present

groups: "wheel"

with_items:

- testuser1

- testuser2

備註：復制上面的代碼，直接執行是不成功的，剛學loops 循環 直接運行無論如何也不能成功，遇到了很多坑。

需要改寫如下:

---
- hosts: web 
  tasks:  
     - name: add several users
       user: 
          name: "{{ item }}"
          state: present
          groups: "wheel"
       with_items:
          - testuser1
          - testuser2

執行 stands.yml ansible-playbook stands.yml

執行效果如下

查看用戶是否創建成功

ansible web -m shell -a "id tsetuser1"

用戶創建成功

實戰演示： 使用loops 循環安裝PHP

---
- hosts: web
  gather_facts: False
  tasks:
     - name: install php packages
       yum:
          name: "{{ item }}"
          state: latest
       with_items:
          -  gcc-c++
          -  php
          -  php-devel
          -  php-fpm

關於 yum 模塊的其他用法,以httpd 為列

name: 安裝最新版本的apache

yum: name=httpd state=latest

- name: 移除apache

yum: name=httpd state=absent

- name: 安裝一個特殊版本的apache

yum: name=httpd-2.2.29-1.4.amzn1 state=present

- name: 升級所有的軟件包

yum: name=* state=latest

- name: 從一個遠程yum倉庫安裝nginx

yum: name=http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm state=present

- name: 從本地倉庫安裝nginx

yum: name=/usr/local/src/nginx-release-centos-6-0.el6.ngx.noarch.rpm state=present

- name: 安裝整個Development tools相關的軟件包

yum: name="@Development tools" state=present

執行 ansible-playbook yum_install_php.yml

執行過程如下

檢查php 是否安裝成功

ansible web -m shell -a "php -v "

PHP 安裝成功

Ansible-playbook 之 loops 循環一
