Configuring Ports

For security reasons, you may need to change AtScale ports from the default. You can make these configuration changes in atscale.yaml, following the procedure below.

Before You Begin

For the following procedure, you must have an AtScale installation of version 7.4.0 or above.

Procedure

If AtScale is not already running, then as the ATSCALE_USER user (atscale by default), run the installed AtScale's configurator.sh script in --first-time mode.

If you don't want to fully confgure yet, answer 'n' when prompted with 'Do you wish to apply this configuration? (y/N):'. This will generate the /opt/atscale/conf/atscale.yaml file and exit before configuring services.
```
/opt/atscale/current/bin/configurator.sh --first-time
```
Open /opt/atscale/conf/atscale.yaml.

Edit /opt/atscale/conf/atscale.yaml to override port entries that need to be changed in the following sections:

engine.ports
modeler.ports
virtualization.supervisor
virtualization.worker
virtualization.listener.port

The current port defaults are listed in the example below:

engine:
   ports:
       http: "20502"
       remoting: "20507"
modeler:
   ports:
       http: "20500"
       authorization: "20503"
virtualization:
   virtualization_supervisor:
       ui_port: "10530"
       driver_port: "10531"
       manager_port: "10532"
       master_port: "10533"
       master_webui_port: "10534"
   virtualization_worker:
       worker_port: "10535"
       worker_webui_port: "10536"
   virtualization_listener:
       port: "10511"

Run configurator.sh to apply the configuration change:
```
/opt/atscale/current/bin/configurator.sh --apply
```
