Reference: workers.properties
Apache httpd Server worker nodes are Servlet containers that are mapped to the mod_jk load balancer.
The worker nodes are defined in HTTPD_DIST/conf/workers.properties. This file specifies where
the different Servlet containers are located, and how calls should be load-balanced across them.
The workers.properties file contains two sections:
Global Properties
This section contains directives that apply to all workers.
Worker Prope rties
This section contains directives that apply to each individual worker.
Each node is defined using the Worker Properties naming convention. The worker name can only
contain alphanumeric characters, limited to [a-z][A-Z ][0-9][_\-].
The structure of a Worker Property is worker.worker_name.directive.
worker
The constant prefix for all worker properties.
worker_name
The arbitrary name given to the worker. For example: node1, node_01, Node_1.
directive
The specific directive required.
The main directives required to configure worker nodes are described below.
Note
