实战ansible批量安装定制好的rpm包
1、项目背景公司最近在生产环境上线内网dns服务器，开源组件选的是powerdns。其中客户端要安装powerdns-recursor，那么疑问来了，线上有100多台server，如何高效快速安装，就得我们运维考虑啦。由于线上之前有部署ansible来批量管理服务器，于是我这的方案就是ansible+定制好的rmp包powerdns-recursor+ansible-doc yum模块。
2、构建本地yum仓库
因为我没找到ansible安装rpm包的模块，所有只能用yum模块，因此先要构造本地yum仓库，详细参考我的另外一篇博客http://hanyun.blog.51cto.com/1060170/1660078
3、构建定制rpm包，后面找时间补上这块的内容
4、前3步准备好以后，接下来安装就很容易。
ansible ttp_www -m yum -a 'name=http://172.16.1.211:81/powerdns-recursor-3.7.3-0.el6.x86_64.rpm state=installed' --sudo
