1 使用Ruby Gem安装Passenger
[root@puppetserver etc]# yum install ruby-devel ruby-libs rubygems libcurl-devel [root@puppetserver etc]# yum install httpd httpd-devel apr-util-devel apr-devel mod_ssl [root@puppetserver repos]# gem install --local passenger-4.0.19.gem #自动解决依赖关系,进入gem包目录进行安装 Building native extensions. This could take a while... Successfully installed rake-10.0.1 Successfully installed daemon_controller-1.1.5 Successfully installed rack-1.5.2 Successfully installed passenger-4.0.19
2 整合Apache和Passenger
[root@puppetserver rpms]# yum install gcc-c++ gcc openssl-devel #源码包编译安装(安装需要apache gcc gcc-c++ openssl-devel开发包的支持) [root@puppetserver etc]# passenger-install-apache2-module #按照相关提示解决依赖关系,安装完成之后会显示 … The Apache 2 module was successfully installed. Please edit your Apache configuration file, and add these lines: LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/buildout/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19 PassengerDefaultRuby /usr/bin/ruby After you restart Apache, you are ready to deploy any number of Ruby on Rails applications on Apache, without any further Ruby on Rails-specific configuration! …
3 配置Apache和Passenger
创建虚拟主机并加载passenger相关模块,注意证书路径要和puppet实际证书路径对应。虚拟主机配置Apache以监听在8140端口,并且使用SSL和Puppet Master生成的证书对所有通讯进行加密。同时还将配置Passenger来使系统的Ruby解释器并且提供Rack配置文件config.ru
的路径
[root@puppetserver conf.d]# vim passenger.conf LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/buildout/apache2/mod_passenger.so <IfModule mod_passenger.c> PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19 PassengerRuby /usr/bin/ruby PassengerHighPerformance on PassengerMaxPoolSize 12 PassengerPoolIdleTime 1500 PassengerStatThrottleRate 120 # RailsAutoDetect On </IfModule> Listen 8140 #监听TCP 8140端口,这是PuppetMaster服务器的标准端口 <VirtualHost *:8140> SSLEngine on #开始ssl加密 SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP #开启ssl加密 SSLCertificateFile /var/lib/puppet/ssl/certs/puppetserver.kisspuppet.com.pem SSLCertificateKeyFile /var/lib/puppet/ssl/private_keys/puppetserver.kisspuppet.com.pem SSLCertificateChainFile /var/lib/puppet/ssl/ca/ca_crt.pem SSLCACertificateFile /var/lib/puppet/ssl/ca/ca_crt.pem SSLCARevocationFile /var/lib/puppet/ssl/ca/ca_crt.pem #打开证书撤销功能,当我们颁发或撤销Puppet agent的证书时,Puppet cert命令会自动更关心ca_crl.pem文件 SSLVerifyClient optional SSLVerifyDepth 1 SSLOptions +StdEnvVars #配置Apache来验证Puppet agent证书的真实性。验证的结果会被保存在这个环境变量中,运行在Passenger中的Puppet master进程会使用这个变量来认证Puppet agent。 #Puppet agent证书验证的结果会以客户端请求头的形式存放在标准环境中。 RequestHeader unset X-Forwarded-For RequestHeader set X-SSL-Subject %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-DN %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-Verify %{SSL_CLIENT_VERIFY}e DocumentRoot /etc/puppet/rack/puppetmaster/public/ RackBaseURI / #Rack为Web服务器提供了用来和Puppet这样的Ruby HTTP服务交换请求和响应的一些常用API。Rack经常被用于在多台Web服务器上部署如Puppet Dashboad这样的web程序。 <Directory /etc/puppet/rack/puppetmaster/> #虚拟主机部分 Options None AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost>
[root@c1.inanu.net]# service httpd configtest #检查apache配置语法是否正确 Warning: DocumentRoot [/etc/puppet/rack/puppetmaster/public/] does not exist Syntax OK
备注:有关puppet虚拟主机配置可参考默认配置
/usr/share/puppet/ext/rack/files/apache2.conf
4 准备config.ru配置文件
[root@puppetserver rack]# mkdir -p /etc/puppet/rack/puppetmaster/{public,tmp} #为Rack和Puppet master的rack程序实例创建框架目录。 [root@puppetserver rack]# cp /usr/share/puppet/ext/rack/files/config.ru /etc/puppet/rack/puppetmaster/ [root@puppetserver rack]# vim /etc/puppet/rack/puppetmaster/config.ru #默认即可 # a config.ru, for use with every rack-compatible webserver. # SSL needs to be handled outside this, though. # if puppet is not in your RUBYLIB: # $:.unshift('/opt/puppet/lib') $0 = "master" # if you want debugging: # ARGV << "--debug" ARGV << "--rack" require 'puppet/application/master' # we're usually running inside a Rack::Builder.new {} block, # therefore we need to call run *here*. run Puppet::Application[:master].run
备注: 如果需要最新的Rack配置文件,可以在Puppet最新发行版的ext目录找到。也可以在https://github.com/puppetlabs/puppet/tree/master/ext/rack/files找到。
[root@puppetserver rack]# chown puppet. /etc/puppet/rack/puppetmaster/config.ru #Rack配置文件config.ru的用户和组应该是puppet。当Apache启动时,Passenger会检查这个文件的所有者,并将其使用的账号从root切换到权限较低的puppet账户。
5 在Apache中测试PuppetMaster
[root@puppetserver ~]# /etc/rc.d/init.d/puppetmaster stop #停止puppetmaster进程 [root@puppetserver ~]# chkconfig puppetmaster off #防止开机自动启动 [root@puppetserver ~]# /etc/rc.d/init.d/httpd start #启动apache服务 [root@puppetserver ~]# chkconfig httpd off #设置开机自动启动 [root@puppetserver ~]# netstat -nlp | grep 8140 #监听8140端口 tcp 0 0 :::8140 :::* LISTEN 4162/httpd
测试一:通过浏览器(IE版本<9)访问https://172.16.200.100:8140/,出现以下信息,说明配置正确
测试二:在节点上运行puppet程序,在服务器端通过apache访问日志查看是否有puppet的请求,如果返回状态吗“200”
表明这次请求时成功的。
[root@puppetserver conf.d]# tailf /var/log/httpd/access_log 172.16.200.101 - - [22/Jul/2013:10:30:34 +0800] "GET /production/file_metadata/modules/mysql/etc/my.cnf?
