Puppet扩展(一)：纵向扩展Apache+Passenger

we23213

1、功能说明
  puppet默认使用基于Ruby的WEBRickHTTP来处理HTTPS请求，
  单个服务器使用Apache+Passenger替换掉WEBRickHTTP，
  Passenger是用于将Ruby程序进行嵌入执行的Apache模块，
  在安装前，首先至少要执行一次service puppetmaster start，生成本地证书
  官方配置指南：https://docs.puppetlabs.com/guides/passenger.html
2、安装apache

1	[iyunv@puppet ~]# yum install -y httpd httpd-devel openssl mod_ssl ruby-devel libcurl-devel rubygems gcc

    前面已安装了apache，这里主要安装mod_ssl ruby-devel libcurl-devel三个。

3、安装passenger

1 2	[iyunv@puppet ~]# gem install rack passenger [iyunv@puppet ~]# passenger-install-apache2-module

    直接回车

    默认选择了Ruby，直接回车

    检查需要安装的包，根据提示安装需要的软件包，再重新执行

1	[iyunv@puppet ~]# yum install libcurl-devel

    需要将此段写入passenger.conf中：

1 2 3 4 5 6

[iyunv@puppet ~]# vi /etc/httpd/conf.d/passenger.conf     LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.53/buildout/apache2/mod_passenger.so                    PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.53             PassengerDefaultRuby /usr/bin/ruby

    继续回车完成，可以看到一个虚拟主机的配置样例。


4、配置rack
  config.ru文件会告诉Rack如何生成puppet master进程

1 2 3 4

[iyunv@puppet ~]# cd /usr/share/puppet [iyunv@puppet puppet]# mkdir -p rack/puppetmasterd/{public,tmp} [iyunv@puppet puppet]# cp ext/rack/config.ru rack/puppetmasterd/ [iyunv@puppet puppet]# chown puppet:puppet rack/puppetmasterd/config.ru

5、配置passenger和vhost

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58

[iyunv@puppet puppet]# cp ext/rack/example-passenger-vhost.conf  /etc/httpd/conf.d/puppetmaster.conf [iyunv@puppet puppet]# vi /etc/httpd/conf.d/puppetmaster.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. # you probably want to tune these settings PassengerHighPerformance on PassengerMaxPoolSize 12 PassengerPoolIdleTime 1500 # PassengerMaxRequests 1000 PassengerStatThrottleRate 120 #RackAutoDetect Off             #注释掉这行 #RailsAutoDetect Off            #注释掉这行 Listen 8140         SSLEngine on         SSLProtocol             ALL -SSLv2 -SSLv3         SSLCipherSuite          EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!IDEA:!ECDSA:kEDH:CAMELLIA256-SHA:AES256-SHA:CAMELLIA128-SHA:AES128-SHA         SSLHonorCipherOrder     on         SSLCertificateFile      /var/lib/puppet/ssl/certs/puppet.ewin.com.pem   #修改路径和证书名称         SSLCertificateKeyFile   /var/lib/puppet/ssl/private_keys/puppet.ewin.com.pem  #修改路径和证书名称         SSLCertificateChainFile /var/lib/puppet/ssl/ca/ca_crt.pem  #修改路径         SSLCACertificateFile    /var/lib/puppet/ssl/ca/ca_crt.pem  #修改路径         # 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  #修改路径         # Apache 2.4 introduces the SSLCARevocationCheck directive and sets it to none         # which effectively disables CRL checking; if you are using Apache 2.4+ you must         # specify 'SSLCARevocationCheck chain' to actually use the CRL.         # SSLCARevocationCheck chain         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 /usr/share/puppet/rack/puppetmasterd/public    #修改路径         RackBaseURI /                    #修改路径                 Options None                 AllowOverride None                 Order allow,deny                 allow from all

6、服务

1 2 3 4

[iyunv@puppet ~]# service puppetmaster stop [iyunv@puppet ~]# service httpd restart [iyunv@puppet ~]# chkconfig httpd on [iyunv@puppet ~]# netstat -nlp | grep 8140

7、测试
（1）WEB网页访问测试
    客户端修改IE设置，去掉标黄的勾：

    使用IE浏览https://10.188.1.73:8140/

    出现这一行表示配置成功，下一节配置Dashboard后就有内容了。
（2）linux客户端测试

1	[iyunv@zabbix ~]# puppet agent --server puppet.ewin.com --test

    没有报错，显示配置版本号及完成时间表示成功。
（3）puppet服务端测试

1	[iyunv@puppet ~]# tailf /var/log/httpd/access_log

    10.188.1.172是windows客户机ywzhou-pc：

    10.188.1.103是linux客户机zabbix：

    客户机发出HTTP GET请求，状态码200表示请求成功，再使用PUT请求提交了一个报告
