1、項目背景
公司最近在生產環境上線內網dns服務器，開源組件選的是powerdns。其中客戶端要安裝powerdns-recursor，那麼疑問來了，線上有100多臺server，如何高效快速安裝，就得我們運維考慮啦。由於線上之前有部署ansible來批量管理服務器，於是我這的方案就是ansible+定製好的rmp包powerdns-recursor+ansible-doc yum模塊。
2、構建本地yum倉庫
因爲我沒找到ansible安裝rpm包的模塊，所有隻能用yum模塊，因此先要構造本地yum倉庫，詳細參考我的另外一篇博客http://hanyun.blog.51cto.com/1060170/1660078
3、構建定製rpm包，後面找時間補上這塊的內容
4、前3步準備好以後，接下來安裝就很容易。
