Ubuntu下nagios安装pnp4nagios插件：

# apt-get install rrdtool

# apt-get install librrds-perl

# apt-get install php5 php5-gd

# tar zxvf  pnp4nagios-0.6.6.tar.gz

# cd pnp4nagios-0.6.6 # /configure --with-nagios-user=nagios --with-nagios-group=nagios # make all # make install # make install-config # make install-init

# mv sample-config/httpd.conf sample-config/nagiosweb.conf

# cp sample-config/nagiosweb.conf /etc/apache2/conf.d/ # vi /etc/apache2/conf.d/nagiosweb.conf

AuthType /usr/local/nagios/etc/htpasswd   (原为AuthType /usr/local/nagios/etc/htpasswd.users)

:wq

# service apache2 restart

# 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

启动npcd服务

# service npcd start

# vi /usr/local/nagios/etc/nagios.cfg  (把前面的注释符"#"去掉)

process_performance_data=1 (原为process_performance_data=0)

host_perfdata_command=process-host-perfdata service_perfdata_command=process-service-perfdata

:wq

# vi /usr/local/nagios/etc/objects/commands.cfg

# 'process-host-perfdata' command definition

define command{        command_name    process-host-perfdata        command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl         } # 'process-service-perfdata' command definition define command{        command_name    process-service-perfdata        command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl        }

:wq

注：要注释掉原有对process-service-perfdata和process-host-perfdata的定义

为主机添加小太阳图标

# vi /usr/local/nagios/etc/objects/yang.cfg

define host { use       linux-server host_name    yang address      192.168.1.10 action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$ }

:wq

为单个服务添加小太阳图标

# vi /usr/local/nagios/etc/objects/yang.cfg

define service {

use        generic-service host_name   yang service_description      check_load check_command       check_nrpe!check_load normal_check_interval     2 action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$

}

:wq

重启 nagios 服务

# service nagios restart

# mv /usr/local/pnp4nagios/share/install.php  /usr/local/pnp4nagios/share/install2.php   (或者直接删除)

注：点击小太阳图标后会出现个测试页面，各项要求都PASS了，会提示你重命名或删除install.php文件，原因不详

# ls /usr/local/pnp4nagios/var/perfdata  (看下面有没有nagios中定义的主机名目录以及目录下面有没有对应服务的rrd文件和xml文件)

注：nagio图像（pnp4nagios）只能显示nagios插件中的服务，以脚本监控的服务不显示图像
