5、遇到的问题

点击页面左侧的MAP和History报错：

TherequestedURL/nagios/sbin/statusmap.cgiwasnotfoundonthisserver.TherequestedURL/nagios/sbin/histogram.cgiwasnotfoundonthisserver.

原因一：因为gd-devel php-gd没有安装的问题，造成NAGIOS在编译时不生成这statusmap.cgi

原因二：nagios编译在前， gd-devel安装在后，造成不生成这statusmap.cgi

解决方法：yum安装gd-devel php-gd，再重新编译安装nagios
