How do I change the default port that Flow components use to communicate with each other?

In some cases, you might need to look at changing the default communication ports.

By default, The Flow Bootstrap communicates with the configuration tool and other Flow components by port 4501. Notice under the Systems Properties the particular port number used by your Flow system:

If required (by Firewalls or other IT policies), this port can be changed to a port that has access through your Firewalls to other Flow components. This will only change the “listening” port of the config tool. To set the port being used by the Flow Bootstrap service, please follow steps below:

  1. Browse to the location where the Flow Bootstrap is installed (default location is C:\Program Files (x86)\Flow Software\Flow\Bootstrap).
  2. Create a file called “Bootstrap.settings” in the Bootstrap folder. The extension of the file is “.settings”
  3. Edit the file with a text editor and add the following line to the file: {"port":"80"}. See example below:

  1. Change the port number to the required port that will have access through you firewall.
  2. Save the file and restart your Bootstrap service.
  3. The Bootstrap will now communicate with the port details as specified in the file.
  4. Deploy your Platform.

Note: These port settings must be the same for all Flow components especially running in a multi-platform environment
