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:1.9.3ruby_dir:/usr/localgem_version:1.8.23bundle_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

[root@puppetansible]#treeroles/ruby_*roles/ruby_delete├──files├──handlers├──meta│└──main.yml├──tasks│├──delete.yml│└──main.yml├──templates└──vars└──main.ymlroles/ruby_install├──files│└──ruby-1.9.3.tar.gz├──handlers├──meta│└──main.yml├──tasks│├──copy.yml│├──delete.yml│└──main.yml├──templates└──vars└──main.yml12directories,10files

playbook安装ruby内容是

[root@puppetansible]#catruby_install.yml----hosts:"`host`"remote_user:"`user`"gather_facts:Trueroles:-common-ruby_install

playbook删除ruby的内容是

[root@puppetansible]#catruby_delete.yml----hosts:"`host`"remote_user:"`user`"gather_facts:Trueroles:-ruby_delete

下面是安装与测试过程

1、安装ruby

[root@puppetansible]#timeansible-playbookruby_install.yml--extra-vars"host=***user=root"--private-key=/root/denglei-key.pemPLAY[***]********************************************************************GATHERINGFACTS***************************************************************ok:[117.121.32.107]TASK:[common|Installinitializtionrequiresoftware]***********************changed:[117.121.32.107]TASK:[ruby_install|CopyRubySoftwareToRedhatClient]********************changed:[117.121.32.107]TASK:[ruby_install|UncompressionRubySoftwareToRedhatClient]***********changed:[117.121.32.107]TASK:[ruby_install|CopyRedisConfigToRedhatClient]*********************changed:[117.121.32.107]=>(item=ruby)changed:[117.121.32.107]=>(item=gem)changed:[117.121.32.107]=>(item=bundle)TASK:[ruby_install|DeleteRubycompressionSoftwareInRedhatClient]******changed:[117.121.32.107]PLAYRECAP********************************************************************117.121.32.107:ok=6changed=5unreachable=0failed=0real0m52.274suser0m2.863ssys0m0.308s

2、安装后测试

3、删除ruby

4、删除后测试

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
