使用Apache+Passenger部署高性能PuppetMaster

前言:

创新互联于2013年成立,先为贵德等服务建站,贵德等地企业,进行企业商务咨询服务。为贵德企业网站制作PC+手机+微官网三网同步一站式服务解决您的所有建站问题。

最近在服务器系统上安装了最新的Puppet客户端,发现跟老版本的PuppetMaster做同步时出现了一些问题,警告类的信息很好解决,注释掉配置文件templatedir该行即可,后来又对PuppetMaster做了次升级,直接升为最新的3.6.1,随后发现PuppetMaster默认安装的WEBrick的web服务器性能较低且最新版本3.6.1存在bug以至于无法同时接受多台Agent客户端请求,因此使用Apache+Passenger方案替代原WEBrick,提高并发性能,同时解决bug带来的问题

环境:

Ubuntu 12.04 64-LTS

PuppetMaster: 3.6.1(升级前版本为3.4.3)

PuppetAgent: 3.6.1

1、安装Apache2

$ sudo apt-get install apache2 ruby1.8-dev rubygems
$ sudo a2enmod ssl
$ sudo a2enmod headers

2、安装Rack/Passenger

$ sudo gem install rack passenger
$ sudo passenger-install-apache2-module
# 按提示解决软件依赖关系后,再次运行命令安装passenger模块
Please edit your Apache configuration file, and add these lines:

LoadModule passenger_module /var/lib/gems/1.8/gems/passenger-4.0.44/buildout/apache2/mod_passenger.so

  PassengerRoot /var/lib/gems/1.8/gems/passenger-4.0.44
  PassengerDefaultRuby /usr/bin/ruby1.8


$ sudo mkdir /etc/puppet/rack
$ sudo mkdir /etc/puppet/rack/{public,tmp}
$ sudo scp /usr/share/puppet/ext/rack/config.ru /etc/puppet/rack/
$ sudo chown -R puppet:root /etc/puppet/rack

3、配置Puppet虚拟主机文件

$ sudo cp /usr/share/puppet/ext/rack/example-passenger-vhost.conf /etc/apache2/sites-available/puppet.conf
$ sudo vim /etc/apache2/sites-available/puppet.conf
# 按之前的提示添加如下内容
LoadModule passenger_module /var/lib/gems/1.8/gems/passenger-4.0.44/buildout/apache2/mod_passenger.so

  PassengerRoot /var/lib/gems/1.8/gems/passenger-4.0.44
  PassengerDefaultRuby /usr/bin/ruby1.8
  PassengerHighPerformance on
  PassengerMaxPoolSize 12
  PassengerPoolIdleTime 1500
# PassengerMaxRequests 1000
  PassengerStatThrottleRate 120
# RackAutoDetect Off                 # 注释该行
# RailsAutoDetect Off                # 注释该行


Listen 8140


        SSLEngine on
        SSLProtocol             ALL -SSLv2
        SSLCipherSuite          ALL:!aNULL:!eNULL:!DES:!3DES:!IDEA:!SEED:!DSS:!PSK:!RC4:!MD5:+HIGH:+MEDIUM:!LOW:!SSLv2:!EXP
        SSLHonorCipherOrder     on
        # 修改为SSL实际路径及文件名
        SSLCertificateFile      /var/lib/puppet/ssl/certs/test.cominggo.com.pem
        SSLCertificateKeyFile   /var/lib/puppet/ssl/private_keys/test.cominggo.com.pem
        SSLCertificateChainFile /var/lib/puppet/ssl/certs/ca.pem
        SSLCACertificateFile    /var/lib/puppet/ssl/certs/ca.pem
        # If Apache complains about invalid signatures on the CRL, you can try disabling
        # CRL checking by commenting the next line, but this is not recommended.
        SSLCARevocationFile     /var/lib/puppet/ssl/crl.pem
        SSLVerifyClient optional
        SSLVerifyDepth  1
        # The `ExportCertData` option is needed for agent certificate expiration warnings
        SSLOptions +StdEnvVars +ExportCertData

        # This header needs to be set if using a loadbalancer or proxy
        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/public/
        RackBaseURI /
        
                Options None
                AllowOverride None
                Order allow,deny
                allow from all
        
        ## Logging        # 设置Puppet访问日志(可选,默认日志为other_vhosts_access.log)
        ErrorLog "/var/log/apache2/puppet_error.log"
        ServerSignature Off
        CustomLog "/var/log/apache2/puppet_access.log" combined


$ cd /etc/apache2/sites-available/
$ sudo a2ensite puppet.conf

4、移除WEBrick服务(puppetmaster),并重启Apache服务

$ sudo /etc/init.d/puppetmaster stop
$ sudo update-rc.d -f puppetmaster remove
$ sudo /etc/init.d/apache2 restart
$ sudo ss -talnp | grep apache2
LISTEN     0      128      *:8140         *:*      users:(("apache2",30037,5),("apache2",29472,5),("apache2",29467,5))
LISTEN     0      128      *:80           *:*      users:(("apache2",30037,3),("apache2",29472,3),("apache2",29467,3))
LISTEN     0      128      *:443          *:*      users:(("apache2",30037,4),("apache2",29472,4),("apache2",29467,4))

5、验证是否部署成功

1)访问HTTPS服务

# 访问页面:https://test.cominggo.com:8140/
The environment must be purely alphanumeric, not ''

2)PuppetAgent节点运行测试

# PuppetAgent:
$ sudo puppet agent -t

# PuppetMaster:查看apache访问日志是否有200状态请求
$ sudo tail /var/log/apache2/puppet_access.log
