Avoiding Port Conflicts

If you are installing a CloudBees Flow server and your web server or other application uses the same ports as the CloudBees Flow host, you must take one of the following actions:

  • Select different web server or application ports

  • Uninstall the existing web server or application

  • Disable the existing web server or application

  • Reconfigure the existing web server or application to use another port
