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 } 6. 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
