Use tomcat webapp as the root path for apache/mod-jk virtualhost

  • 772

I have configured a server where lies several domains, and more than one of them have a ajp13-worker associated to it. The configuration file looks like that:

<VirtualHost *:80>
        ServerAdmin my@email
        ServerName mydomain
        ServerAlias www.domain
        DocumentRoot /home/kleber/www/loja
        JkMount /app* ajp13_worker
        ...
</VirtualHost>

when I deploy some webapps like appOne.war and appTwo.war to my tomcat webapps directory, I can access them using something like that: https://mydomain/appOne and https://mydomain/appTwo.

How I could configure the mod-jk plugin with the tomcat and apache to allow me access some of this webapps as https://mydomain/ only? In a way I could define one webapp per domain using the mod-jk ajp13-worker to be the root path, and allowing me continuing to access the webapps appOne.war and appTwo.war as before.

<VirtualHost *:80>
        ServerAdmin ...
        ServerName ...
        ServerAlias ...
        DocumentRoot /home/kleber/www/loja
        JkMount /app* ajp13_worker

  1. You need an internal rewrite:

    <VirtualHost *:80>
    ServerAdmin my@email
    ServerName loja-de-software.net.br
    ServerAlias www.loja-de-software.net.br
    DocumentRoot /home/kleber/www/loja
    JkMount /app* ajp13_worker

    RewriteEngine  on

    RewriteCond %{HTTP_HOST} loja-de-software.net.br
    RewriteRule /(.*) /appOne/$1 [PT,END]

</VirtualHost>

  2. If you want to make one of the webapp available on the root context, you can rename the war file to ROOT.war and redeploy. That used to work on tomcat8 at least...
