基于学习的目的，演示使用ansible往远程linux服务器上部署nginx。

创建playbook相关目录和文件

mkdir ansible-studymkdir -p ansible-study/filesmkdir -p ansible-study/templatestouch ansible-study/hoststouch ansible-study/web-notls.yml

创建主部署文件web-notls.yml

文件路径：./playbook/ansible-nginx

- name: Configure webserver with nginx  hosts: webservers  sudo: True  tasks:  - name: Nginx Install rpm    yum:       name: http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm  - name: Nginx install nginx    yum:       name: nginx       state: latest  - name: copy nginx config file    copy: src=files/nginx.conf dest=/etc/nginx/sites-available/default  - name: copy index.html    template:        src: templates/index.html.j2       dest: /usr/share/nginx/html/index.html       mode: 0644  - name: restart nginx    service: name=nginx state=restarted

编辑一个nginx配置文件

运行Playbook之前，它还需要2个额外的文件，首先，需要定义个nginx的配置文件
通常来讲，Ansible会将一般文件放在名为files的子目录中，将Jinja2模版文件放在名为templates的子目录中。
文件路径：./playbook/ansible-nginx/files

server {    listen 80 default_server;    listen [::]:80 default_server ipv6only=on;    root /usr/share/nginx/html    index index.html index.htm;    server_name localhost;    location / {        try_files $uri $uri/ = 404;    }}

创建一个定制的首页

添加一个定制的首页，用来测试Nginx的服务正常与否。
文件路径：./playbook/ansible-nginx/templates

<html>    <head>        <title>Welcome to ansible</title>    </head>    <body>        <h1>nginx,configured by Ansible</h1>        <p>If you can see this,Ansible successfully installed nginx.</p>        <p>{{ ansible_managed }}</p>    </body></html>

运行playbook，部署nginx

执行playbook需要使用ansible-playbook命令，按照如下方法运行playbook

LS-MacBook-Pro:ansible-study wangzhen$ ansible-playbook web-notls.yml[DEPRECATION WARNING]: Instead of sudo/sudo_user, use become/become_user and make sure become_method is 'sudo' (default).This feature will be removed in a future release.
