puppet系列之nagios客户端模块

   为了方便与puppet结合着用，所以接下去原本用源码编译的，统统改成用rpmbuild打包完，在放进自己建的源里面，本文也将说明本地源如何创建。

   文中软件包nrpe，和nagios-plugins均由上篇文章的spec生成。

   老规矩，先上架构图(ps:其实都差不多- -)：

   

1.init.pp

import "*"

 

2.web.pp

class nagios::web (
  $nagiospluginsversion="1.4.16-10",
  $nrpeversion="2.13-10"
){
        file {"sa":
          path    => "/root/sa",
          ensure  => directory,
        }

        package {"xinetd":
          ensure  => present,
        }

        package {"nagios-plugins":
          ensure  => $nagiospluginsversion,
        }

        package {"nrpe":
          ensure  => $nrpeversion,
          require => Package["nagios-plugins"],
        }

        file {"nrpe.cfg":
          mode      => 0644,
          owner     => nagios,
          group     => nagios,
          path      => "/usr/local/nagios/etc/nrpe.cfg",
          require   => Package["nrpe"],
          content   => template('nagios/web-nrpe.erb'),
          notify    => Service['xinetd'],
        }

        file {"nrpe":
          mode      => 0644,
          owner     => root,
          group     => root,
          path      => "/etc/xinetd.d/nrpe",
          content   => template('nagios/nrpe.erb'),
          require   => Package["nrpe"],
          notify    => Service['xinetd'],
        }

        service {"xinetd":
          ensure    => running,
          enable    => true,
          subscribe => File["nrpe","nrpe.cfg"],
        }
}

 

3,nrpe.erb

# default: on
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
        flags           = REUSE
        socket_type     = stream
          port              = 5666
        wait            = no
        user            = nagios
          group             = nagios
        server          = /usr/local/nagios/bin/nrpe
        server_args     = -c /usr/local/nagios/etc/nrpe.cfg --inetd
        log_on_failure  += USERID
        disable         = no
          only_from       = 127.0.0.1 <%= nagios_server %>
}

4,nrpe-web.erb

里面就是源码编译出来的nrpe.cfg的内容

5，site.pp 

########################   for module nagios ########################
$nagios_server      = "192.168.10.211"

设置了nagios_server变量的值

6，node调用

(1),modules.pp

import "nagios"

(2),site.pp

node /^redis\.\w+\.com$/ {
    include nagios::web
}

当然也可以写进nodes.pp里面设置的节点里

7，创建本地源

我使用的是ftp来做

(1)yum install vsftpd -y
(2)yum install createrep -y

然后把nrpe,nagios-plugins软件包复制到/var/ftp/pub下，生成依赖关系

createrepo /var/ftp/pub

创建ftp.repo

[ftp]
name=base
baseurl=ftp://192.168.10.211/pub
enabled=1
gpgcheck=0

最后在

yum makecache

别忘了防火墙开启ftp端口
