实际应用- 安装nginx
cd /etc/ansible
mkdir nginx_install
mkdir -p nginx_install/roles/{common,delete,install}/{handlers,files,meta,tasks,templates,vars}
说明：roles目录下有三个角色，common为一些准备操作，delete为删除nginx的操作，install为安装nginx的操作
每个角色下面又有几个目录，handlers下面是当发生改变时要执行的操作，通常用在配置文件发生改变，重启服务。files为安装时用到的一些文件，meta为说明信息，说明角色依赖等信息，tasks里面是核心的配置文件，templates通常存一些配置文件，启动脚本等模板文件，vars下为定义的变量
cd nginx_install/roles
vim ./common/tasks/main.yml //内容如下
- name: Install initializtion require software
yum: name={{ item }} state=installed
with_items:
- gcc
- zlib-devel
- pcre-devel
vim ./install/vars/main.yml
nginx_user: www
nginx_port: 80
nginx_web_dir: /data/www
nginx_version: 1.4.3
ls ./install/files/
nginx-1.4.3.tar.gz
说明： 我们需要把源码包放到 files目录里面
ls ./install/templates
index.html index.php install_nginx.sh nginx nginx.conf vhost.conf
说明： 需要再templates下面准备好 默认页、安装nginx的shell脚本、nginx启动脚本、nginx配置文件以及虚拟主机配置文件
vim ./install/tasks/copy.yml

when: ansible_os_family == "RedHat" and ansible_distribution_version|int >=6
- name: Uncompression Nginx Software To Redhat Client

说明： 首先把压缩包拷贝到/tmp/目录下，然后解压到/usr/local/下，再拷贝启动脚本到/etc/init.d/下，再拷贝nginx.conf以及vhost.conf
