#找一台有apache的服务器，生成nagios页面的验证信息，不然很多页面没有权限访问 ./htpasswd -c nagios.htpasswd nagios New password: nagios Re-type new password: nagios Adding password for user nagios #将该文件放到/usr/local/nagios/etc/nagios.htpasswd #如果没有apache的机器，将如下内容保存为nagios.htpasswd，用户名密码都是nagios，弱口令哦，呵呵

#==============至此，nagios安装完毕 ， 可以访问 试试看了====================
############下面安装的ndoutils组件，可以将nagios的数据写入数据库，然后由Cacti的npc组件在Cacti的页面中展示，即所谓的整合，其实有些坑爹###############
