Multiple Subdomains in Apache / Tomcat with mod_jk

Question

I am currently trying to setup two subdomains for two separate applications running from one Tomcat server and I am having a hard time getting it going.

Without the subdomains I am able to configure one VirtualHost with two mount points and able to get at the applications that way ( looks like http:// url/confluence ) but this is not optimal.

My set up is as follows:

• Subdomain - youtrack.url.com
• Subdomain - confluence.url.com
• Tomcat7 running two war files with the context paths of /confluence and /youtrack
• Apache 2 running mod_jk against tomcat instance

Here is my httpd.conf setup

JkWorkersFile /etc/httpd/conf/workers.properties
JkLogLevel info

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName youtrack.url.com
    ServerAlias www.youtrack.url.com
    JkMount /youtrack* tomcat
    DocumentRoot /var/www/html/youtrack
</VirtualHost>

<VirtualHost *:80>
    ServerName confluence.url.com
    ServerAlias www.confluence.url.com
    JkMount /confluence* tomcat
    DocumentRoot /var/www/html/confluence
</VirtualHost>

Here is my workers.properties

worker.list=tomcat

worker.tomcat.host=localhost
worker.tomcat.port=8009
worker.tomcat.type=ajp13

What appears to be happening is that I hit the DocumentRoot of each subdomain but when I remove the DocumentRoot it never makes it over to the Tomcat web app.

Looking for some help, Thanks.

Updated - here is the mod_jk log

Add this to your Apache web server config:

<VirtualHost youtrack.url.com:80>
    ServerName youtrack.url.com
    JkMount / tomcat
    JkMount /* tomcat
</VirtualHost>

<VirtualHost confluence.url.com:80>
    ServerName confluence.url.com
    JkMount / tomcat
    JkMount /* tomcat
</VirtualHost>

And this to your Tomcats server.xml:

For a single webapps directory (applications deployed with their domain names, see "docbase"):

<Host name="youtrack.url.com" appBase="webapps">
    <Context path="" docBase="youtrack"/>
</Host>

<Host name="confluence.url.com" appBase="webapps">
    <Context path="" docBase="confluence"/>
</Host>

For separate webapps directories (applications deployed as "ROOT"):

<Host name="youtrack.url.com" appBase="ABSOLUTE_PATH\youtrack-webapps" autoDeploy="true" unpackWARs="true" />
<Host name="confluence.url.com" appBase="ABSOLUTE_PATH\confluence-webapps" autoDeploy="true" unpackWARs="true" />
