Starting Control Center for the first time

Use this procedure to start the Control Center service (serviced) on a master host after installing and configuring it. This procedure is valid for single-host and multi-host deployments, whether the deployment has internet access or not, and is only performed once.
  1. Log in to the master host as root, or as a user with superuser privileges.
  2. Verify the configuration settings.
    grep -E '^\b*SERVICED' /etc/default/serviced
  3. Start the Control Center service.
    systemctl start serviced
    To monitor progress, enter the following command:
    journalctl -flu serviced -o cat

    On hosts with internet access, the serviced daemon invokes docker to pull its internal services images from Docker Hub. The Control Center browser and command-line interfaces are unavailable until the images are installed and tagged, and the services are started. The process takes about 5 minutes.

    On hosts without internet access, the serviced daemon tags images in the local registry and starts its internal services. The Control Center browser and command-line interfaces are unavailable for about 3 minutes.

    When the message Host Master successfully started is displayed, Control Center is ready for the next procedure.
