<IfModule dir_module> 
　　DirectoryIndex index.html index.php 
</IfModule> 

# 修改3：修改添加调用php模块
AddType application/x-httpd-php .php 

2、修改Apche主配置文件 /usr/local/apache2/conf/httpd.conf，添加虚拟主机、用户验证

# 配置文件底行加入如下配置
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/sbin">
     AuthType Basic
     Options ExecCGI
     AllowOverride None
     Order allow,deny 
     Allow from all 
     AuthName "Nagios Access"
     AuthUserFile /usr/local/nagios/etc/htpasswd
     Require valid-user
</Directory>
<Directory "/usr/local/nagios/share">
