nagios如何修改Apache？首先安装Apache安装完成后，修改服务apache增加配置文件nagios访问此目录需要身份验证。(注:如果不设置身份验证，则在httpd.conf ***注释添加的内容“加粗字体”部分)
vi /usr/local/apache/conf/httpd.conf

/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.zhaohang zhaohang
# /usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.admin admin
查看认证文件的内容：
less /usr/local/nagios/etc/htpasswd.zhaohang
