Apache does not parse vhost inside the East-redmine, how to solve

Apache does not parse vhost inside the East--redmine
When I configured Apache and redmine, I found the following problems, please also understand to help solve it. THS
I want to achieve access redmine.aaa.com.cn with Vhost.map
Can experiment after found only with virtualhost feasible, this is how to return ah, THS

In the Apache configuration file httpd.conf directly with the VirtualHost port, with http://redmine.aaa.com.cn can access, will normally access to

HTML Code

  
   Redmine
  
   
    
           ServerName redmine.aaa.com.cn         ServerAdmin webmaster@aaa.com.cn         documentroot/usr/ Local/redmine/redmine-1.0/public      
   
    
     
            Options Indexes execcgi followsymlinks         Order allow,deny         allowoverride      
   
       
  
    All  

But I use domain redirection rules, such as
httpd.conf

HTML Code

  
   Rewritecond%{http_host}! (redmine.aaa.com.cn) [Nc]rewritecond%{http_host}! (www.aaa.com.cn) [Nc]rewritemap lowercase int:tolowerrewritemap vhost txt:/usr/local/apache2/conf/ Vhost.maprewritecond ${lowercase:%{server_name}} ^ (. +) $RewriteCond ${vhost:%1} ^ (/.*) $RewriteRule ^/(. *) $%1/$1

Vhost.map as follows:

HTML Code

  
   #redmineredmine. aaa.com.cn/usr/local/redmine/redmine-1.0/public#aaawww.aaa.com/var/www/aaa

The following error occurred:
