nagios安装好后，网页访问出现如下错误：

无权查看任何主机的信息。

请检查HTTP服务器关于该CGI的访问权限设置。

解决办法：

vi /usr/local/nagios/etc/cgi.cfg

将use_authentication的值改为0.

use_authentication=0

然后重启nagios服务

service nagios restart

还有可能：

配置文件中的hostname和service_description使用了中文。

建议hostname和service_description 不要使用中文

}

/usr/local/nagios/bin/nagios -v /usr/locals/nagios/etc/nagios.cfg

/etc/init.d/nagios  reload 这样就可以在图形中监控另外一台主机的根分区，登录用户等信息了。
