# Configure environment slash... ps=\ on NT and / on UNIX ps=/ # Define workers using ajp13 worker.list=tomcat_a0_worker # Set properties for worker worker.tomcat_a0_worker.type=ajp13 worker.tomcat_a0_worker.host=localhost worker.tomcat_a0_worker.port=8009 worker.tomcat_a0_worker.lbfactor=1 |
In the above case are creating a worker called tomcat_a0_worker for a web application to connect to TomcatA which will run in the www.krypton.com virtualhost. Notice the host=localhost line in yellow. This should point to the server that Tomcat is running on. In this case, we are have Apache and Tomcat on the same server so we use localhost.

The load balancing uses weighted round-robin with sticky sessions. The lower the lbfactor number the less weight and as such the less work done by the worker. In our example, since both TomcatA and TomcatB have a factor of 1 the load balance is split about 50/50.

Note that examples is written twice, the reason for this is so that it will recognize the command the same if the person enters /examples or /examples/etc

The above example uses tomcat_a0_worker for the name of the worker. This name depends on what value was used in workers.properties file for worker.list. In this article we had two other examples, |
