naigos實現監控 短信報警

一、nagios在服務端的安裝

# vim nagios-install

#!/bin/bash

#### nagios客戶端安裝請注釋了install nagios這段###

##install nagios

tar zxvf nagios-3.0.6.tar.gz cd nagios-3.0.6 ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios

make all

make install

make install-init

make install-config

make install-commandmode

make install-webconf

cd ..

##install nagios-plugins

tar zxvf nagios-plugins-1.4.13.tar.gz cd nagios-plugins-1.4.13 ./configure --prefix=/usr/local/nagios

make

make install

cd ..

##install nrpe

tar zxvf nrpe-2.12.tar.gz cd nrpe-2.12 ./configure --enable-ssl --enable-command-args

make all

mkdir -p /usr/local/nagios/etc

mkdir -p /usr/local/nagios/bin

cp sample-config/nrpe.cfg /usr/local/nagios/etc/

cp src/nrpe /usr/local/nagios/bin/

sed -i 's/127.0.0.1/127.0.0.1,192.168.1.253/' /usr/local/nagios/etc/nrpe.cfg sed -i 's/usr\/local/nagios/g' /usr/local/nagios/etc/nrpe.cfg

二、啟動nrpe

# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d如需重啟nrpe，先killall -9 nrpe再執行啟動

三、配置nagios

Nagios安裝成功後，在/usr/local/nagios下有幾個目錄，分別是：

bin etc libexec sbin share var

1、在/usr/local/nagios/etc 下建立一個linux的目錄，並建立一個hosts.cfg文件。

這個文件裡面的內容，是分三大塊：(1)、定義主機，即host (2)、定義監控組，即 hostgroup (3)、定義監控主機的服務，即server

例：

# Define webgroup host for the testers machine ##定義主機

define host{

host_name web01

alias web01.com address 192.168.1.10

check_command check-host-alive

max_check_attempts 10

check_period 24x7

notification_interval 20

notification_period 24x7

notification_options d,r

 

; contact_groups admins

name web01

}

define host{

host_name web02

alias web02.com address 192.168.1.20

check_command check-host-alive

max_check_attempts 10

check_period 24x7

notification_interval 20

notification_period 24x7

notification_options d,r

contact_groups admins

name web02

}

define host{

host_name web03

alias web03.com address 192.168.1.20

check_command check-host-alive

max_check_attempts 10

check_period 24x7

notification_interval 20

notification_period 24x7

notification_options d,r

contact_groups admins

name web02

}

##----------------------------------------------------------------------------------------##

### Define all hostgroup for the whole machine ##定義監控組

# Define web group

define hostgroup{

hostgroup_name Web01 Server

alias webserver

members web01,web02 #監控多個機器用逗號隔開

define hostgroup{

hostgroup_name Web02 Server

alias webserver

members web03 #監控多個機器用逗號隔開

##----------------------------------------------------------------------------------------##

#########定義監控主機的服務###########

define service{

host_name web01,web02,web03

&n

bsp; service_description check-procs

is_volatile 0

check_period 24x7

max_check_attempts 1

normal_check_interval 1

retry_check_interval 1

notification_options w,u,c,r

notification_interval 1

notification_period 24x7

check_command check_nrpe!check_total_procs

contact_groups admins #聯系人組

notifications_enabled 1 #此處設定為0，則不報警

}

define service{

host_name web01,web02,web03

service_description check-swap

is_volatile 0

check_period 24x7

max_check_attempts 1

normal_check_interval 1

retry_check_interval 1

notification_options w,u,c,r

notification_interval 1

notification_period 24x7

check_command check_nrpe!check_swap

contact_groups admins

notifications_enabled 1

}

(4)、配置nagios.cfg文件

# cd /usr/local/nagios/etc

# vim nagios.cfg找到cfg_file=/usr/local/nagios/etc/objects/localhost.cfg 這行，並把它注釋

添加cfg_dir=/usr/local/nagios/etc/linux

(5)、配置commands.cfg命令配置文件

# cd /usr/local/nagios/etc/objects

# vim commands.cfg,在文件最後添加

define command {

command_name service-notify-by-fei

command_line /usr/local/fetion/fetion --mobile=1381137*** --pwd=***** --to=$CONTACTPAGER$ --msg-utf8="$HOSTNAME$ $SERVICEDESC$ is $SERVICESTATE$ on $TIME$ resu

lt is $SERVICEOUTPUT$" $CONTACTPAGER$

}

define command {

command_name host-notify-by-fei

command_line &nbs

p; /usr/local/fetion/fetion --mobile=1381137**** --pwd=**** --to=$CONTACTPAGER$ --msg-utf8="Host $HOSTSTATE$ alert for $HOSTNAME$! on '$LO
