[root@nagios nagios-4.0.7]#htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin [root@nagios nagios-4.0.7]#service httpd restart
3、安装nagios-plugins

所有插件命令将被安装到/usr/local/nagios/libexec 目录下
4、其他设置
检查nagios的配置:
[root@nagios ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
添加自动动项:

5、遇到的问题
点击页面左侧的MAP和History报错：
The requested URL /nagios/sbin/statusmap.cgi was not found on this server. The requested URL /nagios/sbin/histogram.cgi was not found on this server.
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
