        register 0

        }

define service {

        name srv-pnp

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

        register 0

        }

或者在在generic-service服务模板中添加下面一句

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

也在local-service模板中添加下面一句

action_url                    /pnp4nagios/index.php?host=$HOSTNAME$

<Directory"/usr/local/pnp4nagios/share">

        AllowOverride None

        Order allow,deny

        Allow from all

        </IfModule>

</Directory>

检查http配置

apachectl -t

重启服务

/etc/init.d/httpd restart

/etc/init.d/nagiosrestart

访问naigos页面，点击Current Load 后面的rrd绘图的图标

提示绿色字体，说明成功，提示重名文件

重命名以下文件

cd/usr/local/pnp4nagios/share

mv install.phpinstall.php.bak

再次刷新页面就正常了。

如果出现红色方框，那就说明没有安装字体

yum install -y  dejavu-lgc-sans-fonts

再次刷新就可以了

如果在网页执行操作时，提示

Could not open command file/usr/local/nagios/var/rw/nagiosNaNd’ for update

解决方法如下:

usermod -a -G nagiosapache

chmod 666/usr/local/nagios/var/rw/nagiosNaNd

chown nagios.nagcmd/usr/local/nagios/var/rw

chmod u+rwx /usr/local/nagios/var/rw

chmod g+rwx/usr/local/nagios/var/rw 

chmod g+s/usr/local/nagios/var/rw
