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
