puppet中nagios客户端模块的示例分析

这篇文章主要为大家展示了"puppet中nagios客户端模块的示例分析"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"puppet中nagios客户端模块的示例分析"这篇文章吧。

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
