yum install perl-Time-HiRes rrdtool rrdtool-perl

2、安装pnp4nagios-0.6.24

wget http://jaist.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios-0.6.24.tar.gz

tar zxvf pnp4nagios-0.6.24.tar.gz

cd pnp4nagios-0.6.24

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

make all

make install

make install-webconf

make install-config

make install-init

3、创建配置文件

cd /usr/local/pnp4nagios/etc/

mv misccommands.cfg-sample misccommands.cfg

mv nagios.cfg-sample nagios.cfg

mv rra.cfg-sample rra.cfg

cd pages

mv web_traffic.cfg-sample web_traffic.cfg

cd ../check_commands

mv check_all_local_disks.cfg-sample check_all_local_disks.cfg

mv check_nrpe.cfg-sample check_nrpe.cfg

mv check_nwstat.cfg-sample check_nwstat.cfg

4、重启服务

service npcd restart

5、修改nagios配置档

1）vi /usr/local/nagios/etc/nagios.cfg

将process_performance_data=0 修改为 process_performance_data=1

将以下两项的#去掉

host_perfdata_command=process-host-perfdata

service_perfdata_command=process-service-perfdata

2）vi /usr/local/nagios/etc/objects/commands.cfg 添加以下内容

define command{
       command_name    process-service-perfdata-file
       command_line    /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$
}
define command{
       command_name    process-host-perfdata-file
       command_line    /bin/mv /usr/local/pnp4nagios/var/host-perfdata /usr/local/pnp4nagios/var/spool/host-perfdata.$TIMET$
}

并将原有# 'process-host-perfdata' command definition、# 'process-service-perfdata' command definition注解删除！

3）vi /usr/local/nagios/etc/objetcs/templates.cfg

添加红色字体内容

define service{

name generic-service

active_checks_enabled 1

passive_checks_enabled 1

parallelize_check 1

obsess_over_service 1

check_freshness 0

notifications_enabled 1

event_handler_enabled 1

flap_detection_enabled 1

failure_prediction_enabled 1

process_perf_data 1

retain_status_information 1

retain_nonstatus_information 1

is_volatile 0

check_period 24x7

max_check_attempts 3

normal_check_interval 10

retry_check_interval 2

contact_groups admins

notification_options w,u,c,r

notification_interval 60

notification_period 24x7

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

process_perf_data 1

}

4）vi /usr/local/nagios/etc/nagios.cfg 修改参数如下

# Bulk / NPCD mode
# 

process_performance_data=1

# *** the template definition differs from the one in the original nagios.cfg
#
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file

# *** the template definition differs from the one in the original nagios.cfg
#
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file

6、检查配置是否有误

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

重启服务

service nagios restart

service httpd restart

7、排错

pnp4nagios输入用户名密码始终不正确具体解决方法

是由于在安装pnp4nagios后在/etc/httpd/conf.d里，已经生成pnp4nagios.conf配置文件

vi /etc/httpd/conf.d/pnp4nagios.conf 将AuthUserFile /usr/local/nagios/etc/htpasswd.user修改为 /usr/local/nagios/etc/htpasswd

The requested URL /nagios/pnp4nagios/index.php/graph was not found on this server

开启apache的php功能

vi /usr/local/httpd/conf/httpd.conf

查找字符串AddType，并增加

AddType application/x-httpd-php .php .php3 .htm .phtml .php4

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

查找字符串DirectoryIndex，并修改为

DirectoryIndex index.html index.php3 index.php default.php

将/etc/httpd/conf.d/pnp4nagios.conf所有内容复制到/etc/httpd/conf/httpd.conf后面

service httpd restart

perfdata directory "/usr/local/pnp4nagios/var/perfdata/localhost" for host "does not。。。。

chown -R nagios.nagcmd /usr/local/pnp4nagios/var/
