puppet杂记（3）

puppet模板模块

puppet类

1、定义类

vim：从当前行至倒数第一行，在非空白字符行前面加空格
:.,$-1s/^[^[:space:]]/   &/g


声明类
[root@master1 manifests]# vim test13.pp 

class nginx {
   $webserver=nginx
   package{$webserver:
        ensure  =>  latest,
   }

   file{'/etc/nginx/nginx.conf':
        ensure  => file,
        source  => '/root/modules/nginx/files/nginx.conf',
        require => Package['nginx'],
        notify  => Service['nginx'],
   }

   service{'nginx':
        ensure  =>  running,
        enable  =>  true,
        hasrestart  =>  true,
        hasstatus   =>  true,
   #    restart =>  'systemctl reload nginx.service',
        require =>  [ Package['nginx'],File['/etc/nginx/nginx.conf'] ]
   }
}

[root@master1 manifests]# puppet apply -v test13.pp 
Notice: Compiled catalog for master1.master1.com in environment production in 0.07 seconds
Info: Applying configuration version '1513291848'
Notice: Finished catalog run in 0.13 seconds

2、声明类（include）

[root@master1 manifests]# vim test13.pp

class nginx {
   $webserver=nginx
   package{$webserver:
        ensure  =>  latest,
   }

   file{'/etc/nginx/nginx.conf':
        ensure  => file,
        source  => '/root/modules/nginx/files/nginx.conf',
        require => Package['nginx'],
        notify  => Service['nginx'],
   }

   service{'nginx':
        ensure  =>  running,
        enable  =>  true,
        hasrestart  =>  true,
        hasstatus   =>  true,
   #    restart =>  'systemctl reload nginx.service',
        require =>  [ Package['nginx'],File['/etc/nginx/nginx.conf'] ]
   }
}

include nginx


测试：
[root@master1 manifests]# puppet apply -v test13.pp 
Notice: Compiled catalog for master1.master1.com in environment production in 2.10 seconds
Info: Applying configuration version '1513293247'
Notice: /Stage[main]/Nginx/Package[nginx]/ensure: created
Info: Computing checksum on file /etc/nginx/nginx.conf
Info: FileBucket got a duplicate file {md5}93bc8e01bfd45e7e18b23acc178ae25b
Info: /Stage[main]/Nginx/File[/etc/nginx/nginx.conf]: Filebucketed /etc/nginx/nginx.conf to puppet with sum 93bc8e01bfd45e7e18b23acc178ae25b
Notice: /Stage[main]/Nginx/File[/etc/nginx/nginx.conf]/content: content changed '{md5}93bc8e01bfd45e7e18b23acc178ae25b' to '{md5}9b2cf71797e8ad03e9812f314ad6b198'
Info: /Stage[main]/Nginx/File[/etc/nginx/nginx.conf]: Scheduling refresh of Service[nginx]
Notice: /Stage[main]/Nginx/Service[nginx]/ensure: ensure changed 'stopped' to 'running'
Info: /Stage[main]/Nginx/Service[nginx]: Unscheduling refresh on Service[nginx]
Notice: Finished catalog run in 21.68 seconds

3、声明类，变量定义参数

[root@master1 manifests]# vim test14.pp 

class nginx($webserver='nginx') {

   package{$webserver:
        ensure  =>  latest,
   }

   file{'/etc/nginx/nginx.conf':
        ensure  => file,
        source  => '/root/modules/nginx/files/nginx.conf',
        require => Package['nginx'],
        notify  => Service['nginx'],
   }

   service{'nginx':
        ensure  =>  running,
        enable  =>  true,
        hasrestart  =>  true,
        hasstatus   =>  true,
   #    restart =>  'systemctl reload nginx.service',
        require =>  [ Package['nginx'],File['/etc/nginx/nginx.conf'] ]
   }
}

include nginx

4、声明变量方式（2）

class nginx($webserver='nginx') {

   package{$webserver:
        ensure  =>  latest,
   }

   file{'/etc/nginx/nginx.conf':
        ensure  => file,
        source  => '/root/modules/nginx/files/nginx.conf',
        require => Package['nginx'],
        notify  => Service['nginx'],
   }

   service{'nginx':
        ensure  =>  running,
        enable  =>  true,
        hasrestart  =>  true,
        hasstatus   =>  true,
   #    restart =>  'systemctl reload nginx.service',
        require =>  [ Package['nginx'],File['/etc/nginx/nginx.conf'] ]
   }
}

class{'nginx':
    webserver => 'tengine',
}

5、类继承

root@master1 manifests]# vim test15.pp

class nginx {
        package{'nginx':
            ensure => latest,
        } ->

        service{'nginx':
            enable => true,
            ensure => running,
            hasrestart => true,
            hasstatus => true,
            restart => 'service nginx reload',
        }
}

class nginx::webserver inherits nginx {
        file{'/etc/nginx/nginx.conf':
                source => '/root/modules/nginx/files/nginx_web.conf',
                ensure => file,
                notify => Service['nginx'],
        }
}

class nginx::proxy inherits nginx {
        file{'/etc/nginx/nginx.conf':
                source => '/root/modules/nginx/files/nginx_proxy.conf',
                ensure => file,
                notify => Service['nginx'],
        }
}

include nginx::webserver


[root@master1 manifests]# puppet apply -v test15.pp 
Notice: Compiled catalog for master1.master1.com in environment production in 2.05 seconds
Info: Applying configuration version '1513353078'
Notice: Finished catalog run in 12.43 seconds
[root@master1 manifests]# 


切换成反代模式：

修改配置文件，类声明
include nginx::proxy


[root@master1 manifests]# puppet apply -v test15.pp 
Notice: Compiled catalog for master1.master1.com in environment production in 1.92 seconds
Info: Applying configuration version '1513353772'
Info: Computing checksum on file /etc/nginx/nginx.conf
Info: /Stage[main]/Nginx::Proxy/File[/etc/nginx/nginx.conf]: Filebucketed /etc/nginx/nginx.conf to puppet with sum 9b2cf71797e8ad03e9812f314ad6b198
Notice: /Stage[main]/Nginx::Proxy/File[/etc/nginx/nginx.conf]/content: content changed '{md5}9b2cf71797e8ad03e9812f314ad6b198' to '{md5}0ba0cf9c84b56c8a0db3bffb55da5002'
Info: /Stage[main]/Nginx::Proxy/File[/etc/nginx/nginx.conf]: Scheduling refresh of Service[nginx]
Notice: /Stage[main]/Nginx/Service[nginx]: Triggered 'refresh' from 1 events
Notice: Finished catalog run in 3.95 seconds

6、覆盖父类属性，父类安装nginx，但是子类想安装t-nginx

[root@master1 manifests]# vim test16.pp 

class nginx {
        package{'nginx':
            ensure => latest,
        } ->

class nginx {
        package{'nginx':
            ensure => latest,
            name => nginx,
        } ->

        service{'nginx':
            enable => true,
            ensure => running,
            hasrestart => true,
            hasstatus => true,
            restart => 'service nginx reload',
        }
}

class nginx::webserver inherits nginx {
        Package['nginx'] {
                name => tengine,
        }

    file{'/etc/nginx/nginx.conf':
            source => '/root/modules/nginx/files/nginx_web.conf',
            ensure => file,
            notify => Service['nginx'],
    }

}

没有tengine报错：
[root@master1 manifests]# puppet apply -v test16.pp 
Notice: Compiled catalog for master1.master1.com in environment production in 1.71 seconds
Info: Applying configuration version '1513355751'

PS； name +> tengine, #原来的nginx之外，额外装个tengine

7、puppet模板，content

修改参数：
[root@master1 files]# vim nginx_proxy.conf 

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes <%= @processorcount %>;


[root@master1 files]# facter -p | grep processorc
physicalprocessorcount => 1
processorcount => 1
[root@master1 files]# 


[root@master1 manifests]# vim test17.pp 

            hasstatus => true,
            restart => 'service nginx reload',
        }
}

class nginx::webserver inherits nginx {
        Package['nginx'] {
                name +> varnish,
        }

        file{'/etc/nginx/nginx.conf':
                source => '/root/modules/nginx/files/nginx_web.conf',
                ensure => file,
                notify => Service['nginx'],
        }
}

class nginx::proxy inherits nginx {
        file{'/etc/nginx/nginx.conf':
                content => template('/root/modules/nginx/files/nginx_proxy.conf'),
                ensure => file,
                notify => Service['nginx'],
        }
}
    
include nginx::proxy


[root@master1 manifests]# puppet apply -v test17.pp 
Notice: Compiled catalog for master1.master1.com in environment production in 1.69 seconds

验证配置文件：
[root@master1 nginx]# vim /etc/nginx/nginx.conf

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes 1;

8、模块

[root@master1 nginx]# puppet module list
/etc/puppet/modules (no modules installed)
/usr/share/puppet/modules (no modules installed)

8.2 创建模块

[root@master1 manifests]# mkdir -pv /etc/puppet/modules/nginx/{manifests,files,templates,tests,lib,spec}mkdir: created directory ‘/etc/puppet/modules/nginx’

	        }
	}
	
	class nginx::proxy inherits nginx {

	                content => template('nginx/nginx_proxy.conf.erb'),
	                ensure => file,
	                notify => Service['nginx'],
	        }
	}
