I want to Configure the Jira-Acces over APJ-Proxy. I proceeded as follows (Following this howto: http://confluence.atlassian.com/display/JIRA/Configuring+Apache+Reverse+Proxy+Using+the+AJP+Protocol) :

1) In the server.xml I activate the AJP:

2) Edit VHOST Konfiguration:

   # Load Proxy-Modules
   LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
   LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so

   # Load AJP-Modules
   LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so


   # Proxy Configuration

   <IfModule proxy_http_module>
      ProxyRequests Off
      ProxyPreserveHost On

      # Basic AuthType configuration
      <Proxy *>
         AuthType Basic
         AuthName Bamboo-Server
         AuthUserFile /var/www/userdb
         Require valid-user

         AddDefaultCharset off
         Order deny,allow
         Deny from all
         Allow from 192.168.0.1
         satisfy any
      </Proxy>

      ProxyPass        /bamboo http://localhost:8085/bamboo
      ProxyPassReverse /bamboo http://localhost:8085/bamboo

      ProxyPass        /jira ajp://localhost:8009/
      ProxyPassReverse /jira ajp://localhost:8009/
   </IfModule>

EDIT:

In the logs if found follow:

//localhost:8080/

But It dosen´t work. Somebody have an idea?
