使用 puppet-apache 安装 apache 服务器。
简介
puppet-apache模块是由puppetlabs公司维护的官方模块，提供完善的apache管理能力
WARNING: Configurations not managed by Puppet will be purged.
如果你之前使用手工配置了Apache服务，想要尝试使用puppet-apache模块管理，请额外小心该模块默认情况下会清理掉所有没有被puppet管理的配置文件！
RPM 安装
yum install puppet-apache -y
安装 Apache
在终端下输入：
puppet apply --debug --modulepath /usr/share/openstack-puppet/modules -ve "include ::apache"
或者创建并编辑一个文件test.pp，并输入：
class { 'apache': }
在终端下输入:
puppet apply --modulepath /usr/share/openstack-puppet/modules /root/test.pp
在约1分钟内（取决于你的网速和虚拟机的性能），你就已经完成了Apache服务的安装，配置和启动了。
安装过程如下：
[root@xiexianbin-cn ~]# puppet apply --modulepath /usr/share/openstack-puppet/modules /root/test.pp
