Nagios http://sourceforge.net/projects/nagios/files/nagios-3.x/nagios-3.2.1/nagios-3.2.1.tar.gz

Nagios-plugins http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.15.tar.gz Pnp4nagios http://sourceforge.net/projects/pnp4nagios/files/PNP-0.6/pnp4nagios-0.6.6.tar.gz/download

Nrpe http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.12.tar.gz

注释（以后可能会遇到一下相关包找不到等）： 可能yum安装会有些问题找不到包，可添加yum源：如：rpmforge源和epel源

wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

rpm -ivh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/x86_64/epel-release-6-5.noarch.rpm

php的一些扩展包找不到就需要添加这两个源：rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm和上面的epel-release-6-5.noarch.rpm

如：php扩展mcrypt就需要epel源；而php的扩展bitset就需要用哦感到rpmforge源。。。

一，安装pnp4nagios

！！！此时安装pnp4nagios就用到了需要的epel源，如果没有epel源

请参考：1、安装epel
# cat /etc/issue
CentOS release 6.2 (Final)
Kernel \r on an \m
# rpm -ivh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/x86_64/epel-release-6-5.noarch.rpm 这里应该对应你服务器的版本

[root@master ~]#yum install pnp4nagios rrdtool

或者源码：安装:

在这之前安装rrdtool和pnp4nagios需要如下包：

yum install -y perl-devel perl-CPAN perl-Time-HiRes

#tar -zxvf pnp4nagios-*.tar.gz
#cd php4nagios-*
#./configure --prefix=/usr/local/pnpnagios --with-nagios-user=nagios --with-nagios-group=nagios （如果单独编译安装的rrdtoool，则使用--with-rrdtool=/usr/local/rrdtool-1.2.xx/bin/rrdtool这样的形式）

#make all
#make install
#make install-webconf
#make install-config
#make install-init

#make fullinstall

(使用这条命令替换所有的make命令， make fullinstall)

还需要：复制所有的pnp4nagios 目录下etc下的*.cfg.simple 复制为*.cfg

cd /usr/local/pnpnagios-*/etc/
88. mv misccommands.cfg-sample misccommands.cfg
89. mv nagios.cfg-sample nagios.cfg
90. mv rra.cfg-sample rra.cfg
91. cd pages/
92. mv web_traffic.cfg-sample web_traffic.cfg
93. cd ../check_commands/
94. mv check_all_local_disks.cfg-sample check_all_local_disks.cfg
95. mv check_nrpe.cfg-sample check_nrpe.cfg
96. mv check_nwstat.cfg-sample check_nwstat.cfg

二，配置nagios

1、修改nagios.cfg

[root@master ~]# vim /etc/nagios/nagios.cfg //修改以下内容

process_performance_data=1 //由0改为1

host_perfdata_command=process-host-perfdata //前面的注释拿掉

service_perfdata_command=process-service-perfdata //注释拿掉

enable_environment_macros=1 //如果有注释拿掉

2、修改commands.cfg

注释掉原有对process-host-perfdata和process-service-perfdata，重新定义：

[root@master ~]# vim /etc/nagios/objects/commands.cfg

define command {

command_name process-service-perfdata

command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl

}

define command {

command_name process-host-perfdata

command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA

}

3、修改配置文件templates.cfg

添加以下内容

[root@master ~]# vim /etc/nagios/objects/templates.cfg

define host {

name hosts-pnp

register 0

action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_

process_perf_data 1

}

define service {

name srv-pnp

register 0

action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$

process_perf_data 1

}

4、修改服务器配置文件cisco_3650.cfg

[root@master ~]# vim /etc/nagios/objects/cisco_3650.cfg

###### define hosts ##########################

define host{

use generic-switch,hosts-pnp

host_name BJ3560G-48

address 172.16.1.1

contact_groups admins

}

##### define services ############

define service{

use generic-service,srv-pnp

host_name BJ3560G-48

service_description PING

check_command check_ping!200.0,20%!600.0,60%

contact_groups admins

}

三、配置apache

修改Apache的配置文件httpd.conf：

[root@master ~]# vim /usr/local/apache/conf/httpd.conf

在AddType application/x-gzip .gz .tgz下，添加下面的配置项：

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

[root@master ~]# /etc/init.d/httpd restart 重启apache服务

可以直接拷贝下面到vim /etc/httpd/conf.d/pnp4nagios.conf

[root@lvs-save conf.d]# cat /etc/httpd/conf.d/pnp4nagios.conf

# SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER

Alias /pnpnagios "/usr/local/pnpnagios/share"

<Directory "/usr/local/pnpnagios/share">

AllowOverride None

Order allow,deny

Allow from all

#

# Use the same value as defined in nagios.conf

#

AuthName "Nagios Access"

AuthType Basic

AuthUserFile /usr/local/nagios/etc/htpasswd

Require valid-user

<IfModule mod_rewrite.c>

# Turn on URL rewriting

RewriteEngine On

Options FollowSymLinks

# Installation directory

RewriteBase /pnpnagios/

# Protect application and system files from being viewed

RewriteRule ^(application|modules|system) - [F,L]

# Allow any files or directories that exist to be displayed directly

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

# Rewrite all other URLs to index.php/URL

RewriteRule .* index.php/$0 [PT,L]

</IfModule>

</Directory>

四、如果访问图不出提示：

TherequestedURL/pnp4nagios/index.php/graphwasnotfoundonthisserver.

那么可能是相关php包没安装：

方法：yum install php*

即可解解以上报错出图问题。

五、如果访问http://IP/pnpnagios需要提供认证而用nagios登录的也不行，那么就执行下一下在生成一个用户进行登录即可！

#htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin 第一次使用htpasswd是用参数-c表示创建目录/usr/local/nagios/etc/htpasswd.users 用于存放用户nagiosadmin 信息！

htpasswd -m /usr/local/nagios/etc/htpasswd.users nagios 这个-m 参数表示在这个文件里面多加一个用户！

注意如果上面配置后在/usr/local/pnpnagios/var/perfdata/ 这么目录下有数据 但是点击游览器访问出图数据时候报错说什么找不到主机图，那么一般是http配置问题！看看pnp4nagios和pnpnagios区别的别名问题！
