Apache, mod_proxy/mod_jk2, Tomcat: You can use Apache as the front end to all requests then forward certain URLs or virtual hosts to Tomcat. This lets you have some content served by Tomcat (e.g. a whole domain, a certain directory on a domain, or your LUNA instance) and other content (e.g. HTML, PHP pages, other websites, etc) served by Apache.
edit the file:
/etc/apache2/sites-available/000-default.conf
or

Enable mod's proxy_ajp and proxy_http:
a2enmod proxy_ajp
a2enmod proxy_http
(may need sudo for this. e.g.: sudo a2enmod proxy_ajp)
Restat Apache:
service apache2 restart
Now when a request reaches your server for a domain followed by /luna (or any of the sub-directories LUNA uses: /las, /editor, /webadmin, /uploader) it will push it to tomcat. It is unlikely any of the other domains you host will have any of those as sub-directories so it will not affect them.
