Puppet--自动化管理postfix

Puppet自动化管理postfix
　　创建postfix模块对应的文件和目录
　　

• [root@master ~]# mkdir -p /etc/puppet/modules/postfix/{files,manifests,templates}
  
• 
  
• [root@master ~]# touch /etc/puppet/modules/postfix/manifests/{init.pp,install.pp,config.pp,service.pp}
  
• 
  
• [root@master ~]# touch /etc/puppet/modules/postfix/files/master.cf
  
• 
  
• [root@master ~]# touch /etc/puppet/modules/postfix/templates/main.cf.erb
  

　　

　　配置install.pp
　　

• [root@master ~]# vim /etc/puppet/modules/postfix/manifests/install.pp
  
• 
  
• 
  
• 
  
•    class postfix::install {
  
• 
  
•        package{["postfix","mailx"]:
  
• 
  
•            ensure=>present,
  
• 
  
•        }
  
• 
  
•    }
  

　　

　　配置config.pp
　　

• [root@master ~]# vim /etc/puppet/modules/postfix/manifests/config.pp
  
• 
  
•    class postfix::config{
  
• 
  
•        File{
  
• 
  
•            owner=>"postfix",
  
• 
  
•            group=>"postfix",
  
• 
  
•            mode=>0644,
  
• 
  
•        }
  
• 
  
•        file{"/etc/postfix/master.cf":
  
• 
  
•            ensure=>present,
  
• 
  
•            source=>"puppet://$puppetserver/modules/postfix/master.cf",
  
• 
  
•           require=>Class["postfix::install"],
  
• 
  
•           notify=>Class["postfix::service"],
  
• 
  
•       }
  
• 
  
•       file{"/etc/postfix/main.cf":
  
• 
  
•           ensure=>present,
  
• 
  
•           content=>template("postfix/main.cf.erb"),
  
• 
  
•           require=>Class["postfix::install"],
  
• 
  
•           notify=>Class["postfix::service"],
  
• 
  
•       }
  
• 
  
•   }
  

　　

　　配置postfix模板文件
　　

• [root@master ~]# vim /etc/puppet/modules/postfix/templates/main.cf.erb
  
• 
  
•    soft_bounce = no
  
• 
  
•    command_directory = /usr/sbin
  
• 
  
•    daemon_directory = /usr/libexec/postfix
  
• 
  
•    mail_owner = postfix
  
• 
  
•    myhostname = <%= hostname %>
  
• 
  
•    mydomain = <%= domain %>
  
• 
  
•    myorigin = $mydomain
  
• 
  
•    mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
  
• 
  
•   unknown_local_recipient_reject_code = 550
  
• 
  
•   relay_domains = $mydestination
  
• 
  
•   smtpd_reject_unlisted_recipient = yes
  
• 
  
•   unverified_recipient_reject_code = 550
  
• 
  
•   smtpd_banner = $myhostname ESMTP
  
• 
  
• setgid_group = postdrop
  

　　

　　配置service.pp文件
　　

• [root@master ~]# vim /etc/puppet/modules/postfix/manifests/service.pp
  
• 
  
•    class postfix::service{
  
• 
  
•        service {&quot;postfix&quot;:
  
• 
  
•            ensure=>running,
  
• 
  
•            hasstatus=>true,
  
• 
  
•            hasrestart=>true,
  
• 
  
•            enable=>true,
  
• 
  
•            require=>Class[&quot;postfix::config&quot;],
  
• 
  
•        }
  
• 
  
•    }
  

　　

　　最后编辑init.pp
　　

• [root@master ~]# vim /etc/puppet/modules/postfix/manifests/init.pp
  
• 
  
•    class postfix{
  
• 
  
•        include postfix::install,postfix::config,postfix::service
  
• 
  
•    }
  

　　

　　Postfix的模板配置完成，接下来需要将该模板应用到节点
　　

• [root@master ~]# vim /etc/puppet/manifests/nodes.pp
  
• 
  
•   class base {
  
• 
  
•        include sudo,ssh
  
• 
  
•    }
  
• 
  
• 
  
• 
  
•    node 'client1.centos' {
  
• 
  
•        include base
  
• 
  
•        include postfix
  
• 
  
•    }
  

　　

　　到节点上检查模块的配置是否生效
　　

• [root@client1 ~]# puppetd   --server  master.puppet --test

　　查看postfix服务状态
　　

• [root@client1 ~]# service postfix status
  
• 
  
• master (pid  30794) 正在运行...
