=> 创建httpd基础模块# mkdir /etc/puppet/modules/httpd/{files,manifests,templates} -pv # tree /etc/puppet/modules/httpd//etc/puppet/modules/httpd/├── files //基础模块所调用的配置文件,agent可以通过puppet协议将files目录所定义的文件下载到本地。├── manifests //主要存放基础模块所使用的类文件及相关资源,如init.pp文件。└── templates//主要存放定义的模板文件,例如虚拟主机的定义等等。3 directories, 0 files=> 存放测试页面或者存放http的配置文件,这里一测试页面为例进行演示。# ls /etc/puppet/modules/httpd/files/index.html=> 定义各资源清单,如package、services、file、init等资源。 manifests主要存放管理代码以及site.pp入口,并根据init.pp定义进行调用资源清单。# cd /etc/puppet/modules/httpd/manifests=> 定义package资源# cat install.ppclass httpd::install {package {'httpd':ensure => installed,allow_virtual => false,require => Class[httpd::file],}}=> 定义file资源,主要用于定义agent获取资源的方式以及属性信息# cat file.ppclass httpd::file {file {"/var/www/html/index.html":ensure => file,owner => root,group => root,source => "puppet:///modules/httpd/index.html"}}=> 定义service资源# cat service.ppclass httpd::service {service {"httpd":ensure => running,enable => true,}}=> 定义init.pp资源主要用于调用manifests所定义的类资源# cat manifests/init.pp class httpd {include httpd::install 调用install资源清单include httpd::service 调用service资源清单include httpd::file 调用文件资源清单}=> 通过正则表达式管理节点 主要用于判断agent所匹配的信息,满足执行相关资源定义,不满足则匹配默认(default)所定义的资源。# cat /etc/puppet/manifests/site.ppnode /^(agent|zabbix)\.gdy\.com$/ { //只有满足主机名为agent.gdy.com和zabbix.gdy.com两台主机,才会加载httpd基础模块,其他则加载default所定义的资源。include httpd}node default { ==> 当agent不满足需求时,则执行通知机制。notify {"Notice error,Not match your node,this is default node":}}=> 通过基础模块的形式部署Apache基本完成,下面我们一起看下测试结果,是否正常安装Apache呢?注意:其他相关组件的安装和定义类似,例如(LNMP/LAMP/tomcat...),大家只需定义相关资源即可。=================> agent端测试:[root@zabbix ~]# hostname zabbix.gdy.com [root@zabbix ~]# rpm -qa | grep httpdhttpd-tools-2.2.15-29.el6_4.x86_64[root@zabbix ~]# puppet agent -tInfo: Retrieving pluginfactsInfo: Retrieving pluginInfo: Caching catalog for zabbix.gdy.comInfo: Applying configuration version '1435386756'Notice: /Stage[main]/Httpd::Install/Package[httpd]/ensure: createdNotice: /Stage[main]/Httpd::Service/Service[httpd]/ensure: ensure changed 'stopped' to 'running'Info: /Stage[main]/Httpd::Service/Service[httpd]: Unscheduling refresh on Service[httpd]Notice: /Stage[main]/Httpd::File/File[/var/www/html/index.html]/ensure: defined content as '{md5}d72717e69f29438790d728bdcad27913'Notice: Finished catalog run in 9.86 seconds[root@zabbix ~]# rpm -qa | grep httpdhttpd-tools-2.2.15-29.el6_4.x86_64httpd-2.2.15-29.el6_4.x86_64[root@zabbix ~]# service httpd statushttpd (pid 1298) is running...[root@zabbix ~]# chkconfig --list httpdhttpd 0:off1:off2:on3:on4:on5:on6:off[root@zabbix ~]# //当前系统主机名为zabbix.gdy.com,满足我们所定义的主机,所以会加载httpd基础模块下的资源。===============================================[root@test01 ~]# hostname test01.gdy.com => 当前主机名为test01.gdy.com,是不满足我们的需求,则会执行default所定义的通知机制。[root@test01 ~]# puppet agent -tInfo: Retrieving pluginfactsInfo: Retrieving pluginInfo: Caching catalog for test01.gdy.comInfo: Applying configuration version '1436147237'Notice: Notice error,Not match your node,this is default nodeNotice: /Stage[main]/Main/Node[default]/Notify[Notice error,Not match your node,this is default node]/message: defined 'message' as 'Notice error,Not match your node,this is default node'Notice: Finished catalog run in 0.05 seconds//当前系统主机名为test01.gdy.com,不满足所定义的主机资源,故执行默认所定义的default资源。=> ok,今天就先到这,谢谢大家
