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

/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

cd/usr/local/nagios/etc/
