　　NAGIOS插件pnp4nagios安装
注：nagios版本nagios4.0.8
　　1.下载安装 pnp4nagios-0.6.25.tar.gz
wget http://sourceforge.net/projects/pnp4nagios/files/PNP-0.6/pnp4nagios-0.6.25.tar.gz
yum -y install rrdtool   perl-Time-HiRes  perl-File-Tail  rrdtool rrdtool-perl php-gd
tar zxvf  pnp4nagios-0.6.25.tar.gz
cd pnp4nagios-0.6.25
　　#perl -MRRDs -le 'print q(ok!)'
如果返回值是ok!，则可以进行pnp4nagios配置和安装
#./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/bin/rrdtool --with-perl_lib_path=/usr/lib64/perl5/vendor_perl/auto/RRDs
#make all
#make  install
#make  install-webconf
#make install-config
#make install-init
　　2.创建配置文件
cd /usr/local/pnp4nagios/etc
mv misccommands.cfg-sample  misccommands.cfg
mv nagios.cfg-sample  nagios.cfg
mv npcd.cfg-sample npcd.cfg
mv process_perfdata.cfg-sample  process_perfdata.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

• 重启服务/etc/init.d/npcd restart
  　　echo “/etc/init.d/npcd start”>>/etc/rc.local
  4.修改 nagios 的配置文件.打开performance_data
  cd /usr/local/nagios/etc
  vim nagios.cfg
  　　#打开注释项：
  process_performance_data=1
  host_perfdata_command=process-host-perfdata
  service_perfdata_command=process-service-perfdata
  #######################添加如下内容####################################
  service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
  service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICEC::HECKCOMMAND::$SERVICECHECKCOMMAND$\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
  host performancedata starting with Nagios 3.0
  　　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
  ###########################################################
  5.修改 commands.cfg
  cd /usr/local/nagios/etc/objects
  vim commands.cfg
  　　##添加
  #################################################################
  define command{
  command_name process-service-perfdata
  command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata
  }
  

　　define command{
command_name process-host-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/host-perfdata
}

• 添加小太阳模版，镶嵌在nagios页面上。vim templates.cfg
  在最后添加
  　　define host {
  name       host-pnp
  action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=HOST
  register   0
  }
  define service {
  name       srv-pnp
  action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
  register   0
  }
  7，修改 hosts.cfg 和services.cfg
  cd /usr/local/nagios/etc/objects
  　　#修改hosts.cfg
  vim hosts.cfg
  　　define host{
          use                      linux-server,host-pnp  
          host_name                  wwwserver
          alias                     wwwserver
          address                   10.10.10.111
          }
  

修改 services.cfg
　　define service{
        use                          local-service,srv-pnp      
        host_name                    wwwserver
        service_description          PING
        check_command                check_ping!100.0,20%!500.0,60%
}
其他的主机和服务以此类推
检查配置文件正确与否
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
　　返回值如上图片，则重启nagios
8.重启 nagios 服务
#/etc/init.d/nagios restart
效果图：

这时点击小太阳会出现如下提示：The requested URL /pnp4nagios/graph was not found on this server.
解决方法如下：
原因，当你在pnp4nagios安装的时候执行了make install-webconf，注意它生成了一个apache的配置文件。
你把这个文件：/etc/httpd/conf.d/pnp4nagios.conf 中的所有内容全部添加到apache的httpd.conf文件最后，再重新启动nagios和apache就应该可以啦。
　　[root@monitor etc]# find / -name pnp4nagios.conf
/etc/httpd/conf.d/pnp4nagios.conf
[root@monitor etc]# vim /etc/httpd/conf.d/pnp4nagios.conf
[root@monitor etc]# cat /etc/httpd/conf.d/pnp4nagios.conf>>/usr/local/apache/conf/httpd.conf
#service httpd restart
#service Nagios restart
这时再点击小太阳，会出现pnp4nagios的测试页，结果如下：
　　告诉要删掉或重命名/usr/local/pnp4nagios/share/install.php
故障2：
安装测试：
http://monitor.dreamlive.tv//pnp4nagios/index.php
　　#cd /usr/local/pnp4nagios/share
#mv install.php install.php.bak
在此测试：显示如下：
　　没有图像出现，主要原因就是：导致
解决方法：
　　改为：
　　重启httpd
结果就正常了
　　报如下错误
　　Yum -y install pango pango-devel
然后重启系统
