Apache subdomain name establishment

The apache subdomain name sets the local environment. the root directory set in the apache configuration file is d:/AppServ/www/. the configuration of the subdomain name is as follows, put it in the configuration file and start NameVirtualHost & nbsp; *: 80 & lt; VirtualHost & nbsp; *: 80 & gt; & nbsp; apache subdomain name settings
In the local environment, the root directory set in the apache configuration file is d:/AppServ/www/. the configuration of the sub-domain name is as follows:

NameVirtualHost *:80


 
  
    ServerName localhost
  
    ServerAlias localhost
  
    DocumentRoot D:/AppServ/www/
  
 
  
    
  
  
#AllowOverride FileInfo Options
  
Options None
  
Order allow,deny
  
Allow from all
  
    
  

  

  

  
   
    ServerName dede
   
    ServerAlias dede
   
    DocumentRoot D:/AppServ/www/Dede/
   
 
   
    
   
   
#AllowOverride FileInfo Options
   
Options None
   
Order allow,deny
   
Allow from all
   
    
   

   

   

   
    
    ServerName ikaihui
    
    ServerAlias ikaihui
    
    DocumentRoot D:/AppServ/www/ikaihui/
    
 
    
    
    
    
#AllowOverride FileInfo Options
    
Options None
    
Order allow,deny
    
Allow from all
    
    
    

    

   
  
 

The current situation is: both dede and ikaihui are displayed normally. if localhost is input, chrome will report this error:

Error 103 (net: ERR_CONNECTION_ABORTED): Unknown error.

IE cannot be opened.
If you delete the localhost section, the dede page will be displayed when you enter localhost. now I want to enter localhost to display index. php under the www folder normally. how can I configure it?
------ Solution --------------------
Check whether it is caused by your anti-virus or firewall.

Your statement is correct.
Clear the browser buffer.
That's what I wrote.

NameVirtualHost *:80


 
  
ServerName localhost
  
DocumentRoot /AMP/web
  

  

  

  
   
ServerName www.a.net
   
DocumentRoot /AMP/web/www.a.net
   

   

   

   
    
ServerName www.b.net
    
DocumentRoot /AMP/web/www.b.net
    

    

   
  
 

------ Solution --------------------
Then you can remove the Directory section.

------ Solution --------------------
Add this.
