Custom Standalone Install
This section describes the options available when installing a standalone AEM instance. You can also read Storage Elements for more information on choosing the backend storage type after freshly installing AEM 6.
Changing the Port Number by Renaming the File
The default port for AEM is 4502. If that port is not available or already in use, Quickstart automatically configures itself to use the first available port number as follows: 4502, 8080, 8081, 8082, 8083, 8084, 8085, 8888, 9362, <*random*> .
You can also set the port number by renaming the quickstart jar file, so that the file name includes the port number; for example, cq5-publish-p4503.jar or cq5-author-p6754.jar .
