Here is an examples of how to configure tomcat-apache connector.

You forgot JkWorkersFile directive. Add this line:

  JkWorkersFile /path/workers.properties

where path is where you saved your workers.properties file.

The port defined by:

  worker.worker1.port=8080

is the port where is listening Tomcat. Check tomcat configuration, usually is 8009.
