需要 rrtool 支持 
yum install rrdtool gd gd-devel php-gd

(1)安装 
#tar -zxvf php4nagios-*.tar.gz 
#cd php4nagios 
#./configure –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) 
#service httpd restart

(2)配置
pnp4nagios有5种模式，配置方法分别如下

• Synchronous Mode: (不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)
• Bulk Mode:(不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)
• Bulk Mode with NPCD：（我使用这种模式）
  
• Bulk Mode with NPCD and npcdmod(不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)
  
• Gearman Mode(不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)

Bulk Mode with NPCD模式的详细配置过程

1. vim /usr/local/nagios/etc/nagios.cfg
   
   • 修改内容
     

     •  process_performance_data=0

       为
       

        process_performance_data=1

   • 增加内容
     

     ## service performance data#service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdataservice_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=aservice_perfdata_file_processing_interval=15service_perfdata_file_processing_command=process-service-perfdata-file## host performance data starting with Nagios 3.0# host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdatahost_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$host_perfdata_file_mode=ahost_perfdata_file_processing_interval=15host_perfdata_file_processing_command=process-host-perfdata-file

2. vim /usr/local/nagios/etc/objects/commands.cfg
   
   增加command
   

   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.$TIMET$}

3. 启动npcd
   
   

   /usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg

4. 重启nagios
   
   

   systemctl restart nagios

5. 检查数据文件是否存在
   
   

   ls -la /usr/local/pnp4nagios/var/service-perfdata

6. 下载verify_pnp_config
   
   

   wget http://verify.pnp4nagios.org/verify_pnp_config

7. 检查pnp4nagios 在bulk+npcd模式下 是否配置正确
   
   

   perl /home/nagios/verify_pnp_config --mode bulk+npcd --config=/usr/local/nagios/etc/nagios.cfg --pnpcfg=/usr/local/pnp4nagios/etc输出内容：[root@nagios_server objects]# perl

(3)集成到nagios的web页面中

• 在/usr/local/nagios/etc/objects/templates.cfg 模板中加入
  

  define host{        name   host-pnp        register   0        action_url    /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_        }

• 在被监控主机对应的cfg文件中，在define host use 一下模板中定于的 host-pnp 就会 在web上显示一个图表的标记

例如：

vim /usr/local/nagios/etc/objects/oa_server.cfg 

define host{ use    windows-server,host-pnp; Inherit default values from a template， host-pnp 就是调用在templates.cfg 中定于的显示图像的功能 ...}

(4)配置apache

pnp4nagios4.10版本apache至此不需要做任何配置，直接就可以访问了，升级到0.6后发现必须rewrite了

安装pnp4nagios 时使用make install-webconf
这个会在/etc/httpd/ conf.d/中生成pnp4nagios.conf文件将其引入到/usr/local/apach2/conf/http.conf文件中

# 使用 pnp4nagiosInclude /etc/httpd/conf.d/pnp4nagios.conf

访问http://server_ip/pnp4nagios  (所有红色的内容都要修正成绿色)
