THS does not parse the stuff in the Vhost in the apache configuration file http Apache -- redmine
When I configured apache and redmine, I found the following problems. please help me solve them .. THS
I want to use vhost. map to access redmine.aaa.com.cn
After the experiment, we can find that it is only feasible to use VirtualHost. how can this problem be solved? THS

In the apache configuration file, httpd. conf directly uses the VirtualHost port, can be accessed with the http://redmine.aaa.com.cn, will be normally accessed

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         Allow from all         AllowOverride all      
      
    

However, I use domain name redirection rules, such
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 is as follows:

HTML code

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

The following error occurs:
Application error
Rails application failed to start properly



------ Solution --------------------
Is it necessary to configure to support AllowOverride?
