运维自动化之ansible playbook安装ruby环境
本来不想打算写安装ruby的，但看几个puppet的群里有人对安装ruby比较茫然，所以这里简单介绍一下如何安装ruby。ps：话说现在也就gitlab、capistrano、puppet等软件使用ruby，最新2010年的软件好的都是python了，比如ansible、salt等。
下面是安装ruby的信息：

ruby_version: 1.9.3
ruby_dir: /usr/local
gem_version: 1.8.23
bundle_version: 1.6.3
可以看到ruby的版本是1.9.3
备注：此playbook仅能对centos或者redhat的6.x版本进行安装。下面是安装ruby的playbook结构

如果大家想使用我的例子，可以从github里下载（地址是https://github.com/dl528888/ansi ... master/ruby_install），然后放到/etc/ansible目录里，下面是内容
