Confluence runs on port 8090 by default. If this port is already in use, the installer will prompt you to choose a different port.
Synchrony, which is required for collaborative editing, runs on port 8091 by default. If this port is already in use, you will need to change the port that Synchrony runs on after your Confluence installation is complete. See Administering Collaborative Editing to find out how to change the port Synchrony runs on. You won't be able to edit pages until Synchrony has an available port.
See Ports used by Atlassian Applications for a summary of all the ports used.
