共计 2438 个字符，预计需要花费 7 分钟才能阅读完成。

一：安装前准备

nagios server：192.168.1.10

nagios client：192.168.1.11

本文安装 Nagios 只使用 Nagios 邮件报警功能，如需画图另外安装 cacti，或其他插件。

二：安装服务

在 nagios server 上操作：

安装 Apache+php

yum install httpd httpd-devel php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml gcc glibc glibc-common gd gd-devel openssl openssl-devel

groupadd nagios

useradd nagios

useradd -G nagios nagios

usermod -G nagios apache

wget http://sourceforge.net/projects/nagios/?source=directory

tar zxvf nagios-3.2.0.tar.gz

cd nagios-3.2.0

./configure –prefix=/usr/local/nagios –with-command-group=nagios

make all

make install

make install-init

make install-config

make install-commandmode

make install-webconf

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

service httpd restart

nagios-plugins 下载地址：www.nagios.org

tar zxvf nagios-plugins-1.4.14.tar.gz

cd nagios-plugins-1.4.14

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

make && make install

wget http://sourceforge.net/projects/nagios-cn/files/latest/download

tar -xjf nagios-cn-3.2.3.tar.bz2

cd nagios-cn-3.2.3

 ./configure

make all

make install

http://sourceforge.net/projects/nagios/files/nrpe-2.x/

tar zxvf nrpe-2.13.tar.gz

cd nrpe-2.13

./configure

make all

make install-plugin

vi /usr/local/nagios/etc/objects/commands.cfg 在最后添加

define command {

    command_name check_nrpe

    command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$

}

检查配置文件是否正确

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

在被监控主机上操作：

useradd -s /sbin/nologin nagios

tar zxvf nagios-plugins-1.4.14.tar.gz

cd nagios-plugins-1.4.14

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

make && make install

tar zxvf nrpe-2.13.tar.gz

cd nrpe-2.13

./configure

make all

make install-plugin

make install-daemon

make install-daemon-config

make install-xinetd

yum install xinetd

vim /etc/xinetd.d/nrpe

将 only_from = 后面加上监控端的地址：192.168.1.10

确保 /etc/services 有 nrpe 5666/tcp #NRPE 这一行，没有则添加

重启 xinetd 服务，至此被监控端配置完毕

/usr/local/nagios/libexec/check_nrpe -H 被监控端的地址

如能显示“NRPE v2.12”，表明 NRPE 可以和被监控端正常通信

安装完毕，接下来开始配置。见 http://www.linuxidc.com/Linux/2014-10/108525.htm
