使用apache管理puppet

puppet可以独立工作，但当在一个成百上千台服务器的大规模集群中部署 Puppet 环境后，各个 Agent 节点与 Master 之间的同步、检查、通讯就会成为瓶颈，会频繁出现连接超时、读取失败等错误。究其原因，由于 Puppet Master 默认使用的 WEBrick 是一个简单的单进程的 WEB SERVER 服务（类似原始的 CGI），因而在大访问量、高并发的情况下就不适用了。所以，要使用性能更好的 Web Server 来提供 Puppet Rails 应用。在实际应用中，通常将其与apache或者nginx结合使用，以解决高并发的问题。

在此，我通过apache借助passenger模块的方式来实现apache和puppet的整合。

puppet master的安装方法在此略过。需要puppet master成功启动过一次，这样会生成相应的证书，方便apache管理。

1.安装ruby环境

yum -y install ruby ruby-devel ruby-irb ruby-rdoc ruby-ri ruby-libs ruby-rdoc openssl-devel

2.安装apache

yum install -y httpd httpd-devel

3.安装rubygems

wget http://rubyforge.org/frs/download.php/76729/rubygems-1.8.25.tgz

tar xf rubygems-1.8.25.tgz

cd rubygems-1.8.25

ruby setup.rb

4.安装passenger

gem install passenger

5.创建apache passenger模块：

passenger-install-apache2-module

6.修改apache主配置文件，按照安装passenger-install-apache2-module模块时给出的提示添加如下内容：

LoadModule passenger_module /usr/lib64/ruby/gems/1.8/gems/passenger-4.0.17/buildout/apache2/mod_passenger.so

PassengerRoot /usr/lib64/ruby/gems/1.8/gems/passenger-4.0.17

PassengerDefaultRuby /usr/bin/ruby

PassengerHighPerformance on

#PassengerUseGlobalQueue on

PassengerMaxPoolSize 3

PassengerMaxRequests 4000

#关闭空闲超过1800秒的passenger实例

PassengerPoolIdleTime 1800

Include conf/extra/puppetmaster.conf #将puppetmaster.conf配置文件载入

7.将puppet源码包中给出的apache的配置文件apache2.conf复制到apache的子配置文件目录中，并重名为puppetmaster.conf

cp /root/puppet-3.2.2/ext/rack/files/apache2.conf /usr/local/apache2/conf/extra/puppetmaster.conf

8.修改puppetmaster.conf文件，如下：

# you probably want to tune these settings

PassengerHighPerformance on

PassengerMaxPoolSize 12

PassengerPoolIdleTime 1500

PassengerMaxRequests 4000

PassengerStatThrottleRate 120

#RackAutoDetect Off

#RailsAutoDetect Off

Listen 8140

SSLEngine on

SSLProtocol -ALL +SSLv3 +TLSv1

SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

SSLCertificateFile /var/lib/puppet/ssl/certs/puppet-master.cmmobi-wh.com.pem

SSLCertificateKeyFile /var/lib/puppet/ssl/private_keys/puppet-master.cmmobi-wh.com.pem

SSLCertificateChainFile /var/lib/puppet/ssl/ca/ca_crt.pem

SSLCACertificateFile /var/lib/puppet/ssl/ca/ca_crt.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/ca/ca_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

</Directory>

</VirtualHost>

9.创建/etc/puppet/rack/public目录，并将puppet源码包自带的config.ru文件复制到/etc/puppet/rack目录下

mkdir -p /etc/puppet/rack/public

cp /root/puppet-3.2.2/ext/rack/files/config.ru /etc/puppet/rack

cp /usr/lib64/ruby/gems/1.8/gems/passenger-4.0.17/test/stub/rails_apps/1.2/empty/public/* /etc/puppet/rack/public/

注：如果是以puppet用户身份来运行puppet，需要将config.ru的属主和属组改成puppet

10.关闭puppet master,启动apache，并检查监听端口，然后用客户端测试

service puppetmaster stop

service httpd start

netstat -ntlp | grep httpd
