NAGIOS服务端安装

一、   主软件包:

1.      nagios-3.0.x.tar.gz                                主程序

2.      nagios-plugins-1.4.x.tar.gz                      插件

3.      nrpe_2.8.x.tar.gz                                  外部构件

4.      pnp -0.4.X                                           图形化工具

二、基本安装:

软件包准备:

 服务端安装:

rpm -q gcc glibc glibc-common gd gd-devel xinetd openssl-devel httpd

安装步骤:

2.1 建立账号:

useradd nagios

passwd nagios

usermod -G nagios nagios

usermod -G nagios apache

2.2 安装nagios-3.0.x.tar.gz

./configure (不用跟参数,默认安装在/usr/local/nagios)

配置完毕按照提示安装

make all

====================

make install

====================

make install-init

====================

make install-config

====================

make install-commandmode

====================

make install-webconf                          #针对rpmapachesourceapache配置见下 ====================

设置收信人地址

vi /usr/local/nagios/etc/objects/contacts.cfg

更改email地址nagiosadmin的联系人定义信息中的EMail信息为你的EMail信息以接收报警内容.

/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd nagiosadmin

输入密码(这一步很重要)

2.3安装Nagios插件

2.3.1    nagios-plugins-1.4.X.tar.gz

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

make

make install

chkconfig --add nagios

chkconfig nagios on

2.3.2    nrpe_2.8.x.tar.gz

./configure

make all

make install-plugins

make install-daemon

make install-daemon-config

make install-xinetd

三、   详细配置:

3.1   主机定义:

vi /usr/local/nagios/etc/objects/hosts.cfg

基本模板:

define host{

            use                     linux-server     # nagios server-name

            host_name              主机名

          alias                   别名

          address                 X.X.X

}

例:

define host {

       host_name                 CentOS

       use                       linux-server,host-pnp

       alias                     nagios server

       address                   192.168.1.44

       contact_groups            nagcmd

       check_command             check-host-alive

       max_check_attempts        5

       notification_interval     10

       notification_period       24x7

       notification_options      d,u,r

       }

      3.2  主机组定义:

           vi /usr/local/nagios/etc/objects/hostgroup.cfg

基本模板:

define hostgroup{

        hostgroup_name  组名

        alias           PAY-web

        members     主机名1, 主机名2     # 须是定义过的

       }

      3.3  服务定义:

           define service{

        use                             generic-service         ; Name of service template to use

        hostgroup_name                  主机组1, 主机组2

        service_description                    Swap Usage

        check_command                  check_nrpe!check_swap

        }

          

例:define service {

        host_name                CentOS

        use                            local-service,srv-pnp

        service_description        CPU

        check_period              24x7

        max_check_attempts      4

        normal_check_interval     1

        retry_check_interval       1

        contact_groups            nagcmd

        notification_interval       10

        notification_period        24x7

        notification_options       w,u,c,r

        check_command          check_nrpe!check_cpu

        }

 

四、   NAGIOS的图形化(PNP

#基于LAMP平台

PNP 是基于PHPPERL,利用rrdtoolNagios采集的数据绘制成图表

软件包列表:

Perl

rrdtool 1.2.*

pnp-0.3.3.tar.gz

4.1 安装rrdtool-1.4.4.*

tar –xvf rrdtool-1.4.4*

./configure    进行配置 –-prefix=/usr/local/rrdtool

make;make install  然后再编译和安装

ls /usr/local/rrdtool-1.4.4.* 查看安装目录是否有

nagios监控服务器_休闲

应该有这些目录才正至此rrdtool安装成功

4.2 安装pnp

tar xzvf pnp-X.r.gz pnp进行解压

cd pnp-X 进入pnp 目录

./configure  --with-rrdtool=/usr/local/rrdtool/bin/rrdtool      --with-perfdata-dir=/usr/local/nagios/share/perfdata/

make all

make install

make install-config

4.2.1  相关设置

首先要将Nagios的主配置文件nagios.cfg中相关的配置修改:

process_performance_data=1

service_perfdata_command=process-service-perfdata  #默认此句被注释掉了

如果想要对某个监控对象做数据图表,则需在所对应的host或者service定义中(一般写在hosts.cfg或者services.cfg文件中),包含如下的定义:

process_perf_data 1

4.3   访问图表

http://IP/nagios/pnp/

这样访问比较麻烦

在服务、主机中添加

1.      object 目录里commands.cfg定义这两个命令:

# 'process-host-perfdata' command definition

define command{

  command_name    process-host-perfdata

#command_line       /usr/bin/printf    "%b"      "$LASTHOSTCHECK$\t$HOSTNAME$\t$HOSTSTATE$\t$HOSTATTEMPT$\t$HOSTSTATETYPE$\t$HOSTEXECUTIONTIME$\t$HOSTOUTPUT$\t$HOSTPERFDATA$\n">>/usr/local/nagios/var/host-perfdata.out

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

        }

# 'process-service-perfdata' command definition

define command{

    command_name    process-service-perfdata

#   command_line   /usr/bin/printf    "%b"      "$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERVICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /usr/local/nagios/var/service-perfdata.out

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

        }

然后在hosts.cfgservices.cfg里面添加host-pnp, srv-pnp


nagios监控服务器_nagios_02


nagios监控服务器_nagios_03

添加之后重启nagios,然后到web下就可以看到
