Puppet单台架构扩展（nginx/apache + passenger）
系统环境：rhel6.5，puppet 3.7.4Master server1.example.com(192.168.88.128)
Agent server2.example.com(192.168.88.129)
原理：使用apache或nginx代替puppet原生态的Webrick以提升master的吞吐量，在master上启webserver以负责监听8140端口并处理客户端的请求、file文件以及验证的客户端请求，将编译部分代理转发到后端的master。极大扩展master能够管理的节点的数量。
Apache+passenger；
一．安装apache和passenger：
yum install httpd httpd-develmod_sslgcc gcc-c++ ruby-devel rubygems
安装passenger
gem installrack passenger（安装过程较慢）#rack 用来让webserver和puppet交换请求和相应的一些 常用API
passenger-install-apache2-module #安装apache模版
#有时gem安装失败，基本是网络原因，更换gem仓库
gem sources –-remove https://rubygems.org/
gem sources -ahttp://ruby.taobao.org/ #淘宝的gem镜像源
二．配置apache
# pwd
/usr/share/puppet/ext/rack #配置文件模板位置
# passenger-config --root #passengerroot 目录
/usr/lib/ruby/gems/1.8/gems/passenger-5.0.6
mkdir /etc/puppet/rack/
cd /etc/puppet/rack
cp example-passenger-vhost.conf/etc/httpd/conf.d/passenger.conf
cp config.ru /etc/puppet/rack/

查看passenger状态：passenger-status
Nginx+passenger
yum install -y gcc gcc-c++ curl-devel zlib-devel openssl-develruby-devel
gem install rack passenger
passenger-install-nginx-module
脚本会自动安装nginx支持，按提示操作，基本就是一路回车。(中间选1自动下载安装，选2为安装本地nginx包)
