Understand moving parts​

Let's first understand what needs to run at a minimum. layline.io consists of three major elements:

Configuration Server​

A process which

  • Serves the Web-based Configuration Center
  • Handles some configuration support services
  • Manages the Project storage

Configuration Center​

A web-based UI which is used for

  • the configuration of layline.io Projects
  • the deployment of Projects to a Reactive Engine / Reactive Engine Cluster
  • the monitoring of one or more Reactive Engine Clusters

Reactive Engine​

A process which

  • executes a Project and Project Workflows
  • is spawned 1..n times on 1..n nodes.

Firewall settings

You may get a firewall warning. Please Allow Access for the Reactive Engine:

Open the Config Center Web UI​

It's time to check if we can start the web-based Configuration Center.

Please note

The Configuration Center is served by the Configuration Server. So make sure that it is up and running.

Open a web browser and enter the url: http://localhost:5841. In case you have installed the Configuration Server on another machine reachable through a different url, then enter the respective url instead of localhost. Should you have changed the port number during installation, you also need to change the port number to what you have set it to.

You should be taken to the login page:

The default login is admin with password admin. Once logged in, you should see this:

Starting issues​

Issues when upgrading from previous version

Should you be upgrading a previously installed version, there is a chance that you may encounter starting issues with the Configuration Server and/or Reactive Engine. The reason being that there are still old configuration elements lingering around. The easiest way to fix the issues would be to follow these steps:

  1. Uninstall layline.io
  2. Locate your layline configuration directory:
C:\Users\<username>\.layline

  1. Delete the above directory (Keep a backup until you know everything runs well post fix)
  2. Reinstall layline.io

The problem should be fixed.
