Web server port
Each web server requires exclusive use of one communication port. By default, web server communication is enabled over SSL.
Important: You can optionally disable SSL communication for a non-production
environment. Enabling SSL communication is highly recommended when integrity and confidentiality of
data transmission is essential.
The web servers are accessible on the following default ports:
| Web server | With SSL | Without SSL |
|---|---|---|
| Web server for the cluster management console | 8443 | 8080 |
| REST web server, which hosts the RESTful APIs for resource management and package deployment | 8543 | 8180 |
| ascd web server, which hosts the RESTful APIs for instance group and application
instance management. Note: If you change the ascd port, update
the value of the ASCD_REST_URL environment variable, which is used by the
SparkCleanup service. The ASCD_REST_URL variable defines the
base URL for the ascd web server and is specified in the
SparkCleanup service profile. For periodic cleanup of instance groups in your
cluster, ensure that this value is defined correctly.

8643 | 8280 |
Check for port conflicts to ensure that the specified ports are free. Since the web server might run on any management host in the cluster, the web server port must be free on all management hosts.
