Apache2 connector installation
I only installed the Apache2 Tomcat connector, since Apache2 is already installed on my server (I use it with Torrentflux):
sudo apt-get install libapache2-mod-jkI then prepared Apache workers configuration file
sudo vim /etc/apache2/workers.properties
workers.tomcat_home=/opt/tomcat
workers.java_home=/usr/lib/jvm/java-6-sun
ps=/
worker.list=default
worker.default.port=8009
worker.default.host=localhost
worker.default.type=ajp13
worker.default.lbfactor=1
