CycleCloud uses the cycle_server.properties file, located under the /opt/cycle_server/config/ directory on Linux systems, to pass the configuration parameters to the CycleServer application and Tomcat application server. The most common reason for updating this file is to configure SSL for the application server. For more information, see the SSL Configuration How-to Guide.
Important
When editing the cycle_server.properties file, first look for preexisting key-value definitions. If the file contains more than one definition, the last one is in effect.
