一、Nagios安装

1，安装基础支持套件

yuninstall -y gcc glibc glibc-common gd gd-devel xinetd openssl-devel httpd php*

 

2，创建nagios用户和用户组

 

useradd-s /sbin/nologin nagios

mkdir/usr/local/nagios

chown-R nagios.nagios /usr/local/nagios

 

3，编译安装Nagios

 

 wgethttp://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.5.0.tar.gz

 

 tarzxvf nagios-3.5.0.tar.gz

 

 cdnagios

 

 ./configure--prefix=/usr/local/nagios

 

makeall

 

makeinstall

 

makeinstall-init

 

makeinstall-config

 

makeinstall-commandmode

 

makeinstall-webconf

 

 

 

验证程序是否被正确安装

 

切换目录到安装路径（这里是/usr/local/nagios），看是否存在etc、bin、sbin、share、var这五个目录，如果存在则可以表明程序被正确的安装到系统了。Nagios各个目录用途说明如下：

 

binNagios可执行程序所在目录

etc  Nagios配置文件所在目录

sbin      NagiosCGI文件所在目录，也就是执行外部命令所需文件所在的目录

share    Nagios网页文件所在的目录

libexecNagios外部插件所在目录

var  Nagios日志文件、lock等文件所在的目录

var/archives      Nagios日志自动归档目录

var/rw  用来存放外部命令文件的目录

 

4，安装Nagios plugins

 

 wgethttp://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-2.0.2.tar.gz

 

 tarzxvf nagios-plugins-2.0.2.tar.gz

 

 cdnagios-plugins-2.0.2

 

 ./configure--prefix=/usr/local/nagios -with-nagios-user=nagios --with-nagios-group=nagios

 

 make&& make install

 

 

5，安装NRPE 

 

wgethttp://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.15.tar.gz

 

tarzxvf nrpe-2.15.tar.gz

 

cdnrpe-2.15

 

./configure

 

makeall

 

makeinstall-plugin

 

makeinstall-daemon

 

makeinstall-daemon-config

 

 

6,创建nagios web登陆账号

 

htpasswd-c /usr/local/nagios/etc/htpasswd.users test

 

 

7,检查其主配置文件的语法是否正确：

 

/usr/local/nagios/bin/nagios-v /usr/local/nagios/etc/nagios.cfg

 

 

 

 

二、安装 rrdtool+pnp4nagios

 

1，rrdtool安装

 

yum-y install http://support.mathias-kettner.de/1.2.2b4/omd-1.2.2b4.dmmk-rh70-30.x86_64.rpm

 

yum-y install perl-rrdtool rrdtool 

 

yuminstall libxml2 libxml2-devel

 

 

2，查看http配置

 

greprewrite /etc/httpd/conf/httpd.conf 

 

LoadModulerewrite_module modules/mod_rewrite.so 

 

3，下载安装pnp4nagios

 

wgethttp://cdnetworks-kr-1.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios-0.6.22.tar.gz

 

tarzxvf  pnp4nagios-0.6.22.tar.gz

 

cdpnp4nagios-0.6.22

 

./configure--with-nagios-user=nagios --with-nagios-group=nagcmd

 

makeall

 

makeinstall

 

makeinstall-webconf

 

makeinstall-init

 

4，创建配置文件

cd/usr/local/pnp4nagios/etc

 

mvmisccommands.cfg-sample  misccommands.cfg

 

mvnagios.cfg-sample  nagios.cfg

 

mvnpcd.cfg-sample npcd.cfg

 

mvprocess_perfdata.cfg-sample  process_perfdata.cfg

 

mvrra.cfg-sample rra.cfg

 

cdpages

 

mvweb_traffic.cfg-sample web_traffic.cfg

 

cd../check_commands

 

mvcheck_all_local_disks.cfg-sample  check_all_local_disks.cfg

 

mvcheck_nrpe.cfg-sample  check_nrpe.cfg

 

mvcheck_nwstat.cfg-sample  check_nwstat.cfg

 

5，重启服务

 

/etc/init.d/npcdrestart

 

6，修改 nagios的配置文件

 

cd/usr/local/nagios/etc

 

vimnagios.cfg

 

打开注视项：

 

process_performance_data=1

 

host_perfdata_command=process-host-perfdata

 

service_perfdata_command=process-service-perfdata

 

修改 commands.cfg

cd/usr/local/nagios/etc/objects

 

vimcommands.cfg

 

添加

 

'process-host-perfdata'command definition

definecommand{

       command_name    process-host-perfdata

       command_line   /usr/local/pnp4nagios/libexec/process_perfdata.pl

       }

 

 'process-service-perfdata'command definition

definecommand{

       command_name    process-service-perfdata

       command_line   /usr/local/pnp4nagios/libexec/process_perfdata.pl

       }

 

添加小太阳模版

 

nagios$> vim templates.cfg

 

在最后添加

 

definehost {

name      host-pnp

action_url/pnp4nagios/graph?host=$HOSTNAME$&srv

register  0

}

defineservice {

name      srv-pnp

action_url/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$

register  0

}

 

 

7，修改 hosts.cfg和 services.cfg
