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

playbook安装ruby内容是
[root@puppet ansible]# cat ruby_install.yml
---
- hosts: "`host`"
remote_user: "`user`"
gather_facts: True
roles:
- common
- ruby_install
playbook删除ruby的内容是
[root@puppet ansible]# cat ruby_delete.yml
---
- hosts: "`host`"
remote_user: "`user`"
gather_facts: True
roles:
- ruby_delete
下面是安装与测试过程
1、安装ruby
[root@puppet ansible]# time ansible-playbook ruby_install.yml --extra-vars "host=*** user=root" --private-key=/root/denglei-key.pem

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/ansible-examples/tree/master/ruby_install），然后放到/etc/ansible目录里，下面是内容
