上面在cacti 安装配置中已经安装,这里就不再进行安装了

centos 7 yum 安装nagios

yum install nagios

yum install nagios-plugins-all


1、tar -zxvf nagios ...tar.gz

#useradd nagios

#passwd nagios

#cd nagios..

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

#make all

#make install

#make install-init

# make install-commandmode

#make install-config

#make install-webconf安装到了Apache目录下conf.d目录了

#make install-exfoliation

#make install-classicui

#修改httpd.conf里的UserGroupnagios 改了之后cacti注意,能不能使用cacti了


2、编译安装nagios-plugins-2.0 #./configure --prefix=/usr/local/nagios

#make&&make install

3、安装nrpe#tar �Czxvf nrpe-2.9.tar.gz

#./configure �Cprefix=/usr/local/nagios

#make all

#make install-pluhin

#make install-daemon

#make install-daemon-config

#chown�CR nagios:nagios /usr/local/nagios

#更改/usr/local/nagios/etc/cgi.cfg 里面nagiosadmin 改成nagios

#service nagios start

#service httpd start

#service MysqL start

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

#vim nagios/etc/objects/command.cfg 添加

define command{

command_name check_nrpe

command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -t 30

}

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

#/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

被监控主机配置:

4、安装nrpe

#./configure --prefix=/usr/loca/nagios

#make all && make install-plugin && make install-daemon && make install-daemon-conig

#vim /usr/local/nagios/etc/nrpe.conf 添加监控服务器IP

allowed_hosts=127.0.0.1,10.1.13.176

#/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.conf -d 开启的端口是5666

#安装nagios-plugin

5、添加需要监控的插件和程序

#vim nrpe.conf ##例:

command[check_swap]=/usr/local/nagios/libexec/check_swap -w 50% -c 20%

6、yum installnet-snmp-libs net-snmp-utils net-snmp


监控主机配置nrpe service


#mkdir server

#vim nagios.conf 添加 cfg_dir=/usr/local/nagios/etc/server

#vim/usr/local/nagios/etc/server/group.cfg

define hostgroup{

hostgroup_name Servers ; The name of the hostgroup

alias Servers ; Long name of the group

}

define hostgroup{

hostgroup_name backup ; The name of the hostgroup

alias backup ; Long name of the group

}


#cd /usr/local/nagios/etc/server && vim 10.1.13.213.cfg



define host{

use linux-server ; Name of host template to use

; This host definition will inherit all variables that are defined

hostgroups Servers

; in (or inherited by) the linux-server host template definition.

host_name 10.1.13.213

alias backup

address 10.1.13.213

}

define service{

use generic-service

service_description Ping

check_command check_ping!100.0,20%!150.0,60%

define service{

use generic-service ; Name of service template to u se

host_name 10.1.13.213

service_description Root Partition

check_command check_nrpe!check_sda1

service_description Current Users

check_command check_nrpe!check_users

service_description Total Processes

check_command check_nrpe!check_total_procs

service_description Current Load

check_command check_nrpe!check_load

service_description Swap Usage

check_command check_nrpe!check_swap

service_description SSH

check_command check_ssh!-p 2222!10.1.13.213

define service{

service_description HTTP

check_command check_nrpe!check_http

host_name 10.1.13.213

service_description zombie_proces

check_command check_nrpe!check_zombie_procs

}


#上面的红色字体,在被监控主机的nrpe.conf 的command 中要定义

监控MysqL

#cd check_MysqL_health

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

#make && make install

#./usr/local/nagios/libexec/check_MysqL_health 出现Can't locate Time/HiRes.pm in @INC 的perl 错误解决办法:安装

#yum install -y perl-Time-HiRes

#vim 10.1.1.13.213.cfg

define service{

use local-service

host_name 10.1.13.213

service_description MysqL

check_command check_nrpe!check_MysqL_health

}

在被监控的主机上:#vim nrpe.conf 添加command[check_MysqL_health]=/var/www/nagios/libexec/check_MysqL_health--hostnamelocalhost--usernameroot--port3306--password910218--modethreads-connected

#MysqL -u root -p

>grant all privileges on *.* to 'root'@'%' identified by '910218';

>flush privileges;

>quit

在主监控服务器上测试被监控机上的MysqL连接:MysqL -u root -p 10.1.13.213

定义时间段和联系人

#vim timeperiods.cfg

define timeperiod{

name workday

timeperiod_name workday

alias workday

monday 00:00-24:00

tuesday 00:00-24:00

wednesday 00:00-24:00

thursday 00:00-24:00

friday 00:00-24:00

define timeperiod {

name weekends

timeperiod_name weekends

alias weekends

saturday 00:00-24:00

sunday 00:00-24:00

#vim templates.cfg

define contact{

name kobe

service_notification_period workday

host_notification_period workday

service_notification_options w,u,r,f,s

host_notification_options d,255);"> host_notification_commands notify-service-by-email

service_notification_commands notify-service-by-email

#vim contacts.cfg

definecontact{
contact_namekobe
usekobe
aliasbryant
host_notification_periodworkday
service_notification_periodworkday
emailroot@localhost
}

#service group 服务组

#vim object/servicegroup.cfg

define servicegroup{

servicegroup_name kobeservicegroup

alias kobeservicegroup

}

servicegroup_name bryantservicegroup

alias bryantservicegroup

}

#vim conf.d/10.1.13.213.cfg 添加servicegroups 名字
