YugabyteDB universes use a set of default ports to manage access to services.
When deploying a universe, YugabyteDB Anywhere allows you to customize these ports.
On the Create Universe > Primary Cluster page, under Advanced Configuration, enable the Override Deployment Ports option, as shown in the following illustration:
Replace the default values with the values identifying the port that each process should use. Any value from
65535 is valid, as long as this value does not conflict with anything else running on nodes to be provisioned.
After deployment, you can modify the YCQL API and admin UI endpoint ports. To change ports, navigate to your universe, click Actions, choose Edit YCQL Configuration, and select the Override YCQL Default Ports option.
If you change the YCQL API endpoint on an active universe, be sure to update your applications as appropriate.
