CENM Management Console

The CENM management console is a web interface that allows you to perform key CENM tasks using a visual UI.

You can use the CENM management console to perform key CENM tasks and access CENM services and network information. With the CENM management console, you can:

• Access the network map.
• Update Network Parameters.
• Review Identity Manager progress for Onboarding and Removing members.

To use the CENM management console, you must install it as a plug-in to your Gateway Service. Once you have installed the plug-in, anyone with the required permissions can access and use the management console from any web browser.

Installation

Requirements

• Auth Service that has been set up with at least one user (ideally an admin user) and running.
• Zone Service running.
• Gateway Service is installed and running.

Install the CENM management console

The CENM management console is accessed via the Gateway Service. Once you have added the plugin binaries to the correct directory on the machine that hosts your Gateway Service, you can access the web service from any browser.

To install the CENM management console:

1. Download the latest Gateway Service binaries from the Customer Hub.
2. Download the CENM management console Gateway Plugin binaries from the Customer Hub.
3. Create a directory called plugins in the same directory as the Gateway Service JAR file (if you do not already have this directory for other plug-ins).
4. Copy the CENM Gateway Plugin JAR file to the plugins directory.
5. Configure the Gateway Service using the auth { } and cenm { } properties. Example configuration:

   auth {
        serverUrl = "https://auth-service:8081/"
        sslConfig = {
            trustStore = "/etc/corda/trust-stores/corda-ssl-trust-store.jks"
            trustStorePassword = "trustpass"
        }
        clientCredentials = {
            clientId = "farm1"
            clientSecret = "secret1"
        }
    }
    cenm {
        zoneHost: "zone-service"
        zonePort: 5063
        ssl = {
            keyStore = {
               keyPassword = "password"
             location = "/etc/corda/key-stores/farm-ssl-keys.jks"
               password = "password"
            }
            trustStore = {
               location = "/etc/corda/trust-stores/corda-ssl-trust-store.jks"
               password = "trustpass"
            }
           }
    }
    server {
        port = 8081
    }
   

6. Launch the Gateway Service.
7. Open your browser and use the Gateway Service’s host and the port property from the configuration (localhost:8081 in the example above).
   Internet Explorer 11 is not supported for this tool.
8. The login page is displayed. Log in using the initial user credentials.
9. You can either open the USER ADMINISTRATION page to manage users, groups, and roles (please note that this requires admin rights), or open the CENM management console to manage your CENM instance.
