关于puppet的扩展APACHE2 + PASSENGER
前言：本篇博客参考了<puppet实战>这本书，测试环境为OpenSuSe13.2+ruby2.1+Apache2.4+Puppet3.7.1 master,Puppet agent为2.7的版本
在领略了puppet种种神奇后，由于puppet通过catalog来更新内容，期间还可能下载插件，下载file，同步file的内容等，这必然要消耗掉master的诸多性能，在获取的过程中master和agent说白了是https的通信，agent通过ruby内置的Webrick服务器获得catalog，而现在流行的webserver肯定对于静态内容效率与效果要更好，于是对master的扩展的一种方式演变为webserver的升级

检查语法错误,下面错误不是重点就不管了
httpd2 -t
AH00558: httpd2: Could not reliably determine the server's fully qualified domain name, using 172.16.236.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK
systemctl start apache2
netstat -tnlp|grep 8140
tcp 0 0 :::8140 :::* LISTEN 11371/httpd2-prefor
这是apache端已经配置好，还要启动master才行，否则会报500的错误

puppet master start
回到我们的agent端进行测试

就实现了nginx辅助进行catalog的传递这个过程
