puppet使用SSL(https)协议来进行通讯，默认情况下，puppet server端使用基于Ruby的WEBRick HTTP服务器。由于WEBRick HTTP服务器在处理agent端的性能方面并不是很强劲，因此需要扩展puppet，搭建Apache或者其他web服务器来处理客户的https请求。
Passenger是一个将Ruby程序嵌入执行的apache的一个模块,它可以让你运行Rails,即Rack应用内的一个Web服务器.能够自动增减集群进程的数量.能提高性能并增加Master和agent之间的并发连接数量。
工作原理如下:
安装好apache和passenger,然后配置apache处理puppet agent的SSL验证请求,最后将apache连接到puppet master.在处理SSL验证请求时,apache会验证puppet agent的证书是否由puppet CA签发,apache 会先验证请求.如果授权通过,则调用master.同时,apache会提供给puppet agent一个证书用于验证服务器的真实性,再将SSL证书存放在适当的位置.打开passenger模块并为puppet master服务创建一个虚拟主机来配置apache.
下面来配置一番:
1.安装apache等相关组件
yum install httpd httpd-devel mod_ssl ruby-devel rubygems libcurl-devel
2.使用ruby gem安装passenger
更换gem镜像 使用淘宝源:
gem sources --remove http://rubygems.org/ gem sources -a http://ruby.taobao.org/ gem sources -l *** CURRENT SOURCES *** http://ruby.taobao.org/
gem install rack passenger #安装passenger passenger-install-apache2-module #整合apache和passenger 按照相关提示解决依赖关系 安装过程会提示配置apache虚拟主机时需要增加passenger模块配置文件 LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.55/buildout/apache2/mod_passenger.so <IfModule mod_passenger.c> PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.55 PassengerDefaultRuby /usr/bin/ruby </IfModule> 查看passengeroot目录. [email protected]:~# passenger-config --root /usr/lib/ruby/gems/1.8/gems/passenger-4.0.55
3.配置apache和passenger
需要在puppet master创建rack应用,创建一个目录用来存放config.ru配置文件,并创建一个虚拟主机配置文件.rack为web服务器提供了用来和puppet服务交换请求和响应的一些常用API.Rack适用于Ruby类的HTTP服务,可以用于多台服务器之间部署服务.
创建rack框架目录,拷贝配置文件,赋予puppet权限.
mkdir -p /etc/puppet/rack/puppetmaster/{public,tmp}
cp /usr/share/puppet/ext/rack/config.ru /etc/puppet/rack/puppetmaster/
chown puppet. /etc/puppet/rack/puppetmaster/config.ru
配置apache虚拟主机文件:
cp /usr/share/puppet/ext/rack/example-passenger-vhost.conf /etc/httpd/conf.d/puppet.domain.com.conf
vim /etc/httpd/conf.d/puppet.domain.com.conf
# This Apache 2 virtual host config shows how to use Puppet as a Rack
# application via Passenger. See
# http://docs.puppetlabs.com/guides/passenger.html for more information.
# You can also use the included config.ru file to run Puppet with other Rack
# servers instead of Passenger.
