Installing the Genesys Web Engagement Server

The 8.5 release of Genesys Web Engagement incorporates two major changes in the server architecture:

  • The Web Engagement Frontend Server and Backend Server have been consolidated into a single Web Engagement Server.
  • In order to simplify the configuration process, you must configure a Web Engagement Cluster application object, even if you are only using a single node.

Each of these changes enhances the performance and the simplicity of Web Engagement.

Important
Before using Genesys Web Engagement, you must either create and deploy your own Web Engagement application or deploy the provided sample application. Otherwise, the product will not work.

After Genesys Web Engagement is ready to use, but before you use it, Genesys recommends that you verify the status of your Cassandra cluster and your Elasticsearch cluster.

About the Web Engagement Cluster

Genesys Web Engagement is built on the principles of N+1 architecture. This means that:

  • The cluster combines 1 or more nodes. In other words, you must create and configure at least one node in order to use Web Engagement. And every time you add another node, you need to create and configure it using the same steps you used to create and configure the first one.
  • All nodes are treated as equivalent to each other, so that almost all of the configuration is defined in the cluster application, while the nodes only contain the options required to connect to a particular host and their cluster.
  • All server connections, such as Interaction Server and Chat Server, are defined for the cluster.
    Note: Web Engagement supports a connection to the Interaction Server Proxy as an alternative to a direct connection to Interaction Server.
  • Connections to external clusters, such as a cluster of Chat Servers, must be configured in the cluster application, rather than adding connections to particular nodes. In other words, if you add nodes to the cluster, you don't have to reconfigure the existing nodes and cluster, whether you are migrating from one node to two nodes, or adding a thousand nodes to the system.

These features make it easy to maintain your cluster configuration and help you avoid faulty configuration scenarios.

Configuring the Cluster Application

Note: For more information on how to work with application objects in Genesys Administrator, consult Generic Configuration Procedures.


Prerequisites

Start

  1. If your Cluster application form is not open in Genesys Administrator, navigate to Provisioning > Environment > Applications. Select the application defined for the Web Engagement Cluster and click Edit....
  2. In the Connections section of the Configuration tab, click Add. The Browse for applications panel opens. Select the Genesys application defined for Interaction Server, then click OK.
    Note: Web Engagement supports a connection to the Interaction Server Proxy as an alternative to a direct connection to Interaction Server.

    The port ID is set to the default port.
  3. Repeat the previous step for Stat Server. Optionally, you can also add a connection to Message Server (to apply the network logging option).
  4. Configure a connection to the Chat Server or to a cluster of Chat Servers. If you are using a single Chat Server, you must set your port ID to webapi when specifying your connection to Chat Server. For information on how to connect a cluster of Chat Servers, see Configuring a Connection to a Cluster of Chat Servers (Optional).
  5. Expand the Server Info pane.
  6. In the Tenant section, click Add and select your tenant. For instance, Environment. Click OK.
  7. If your Host is not defined, click the lookup icon to browse to the hostname of your application.
  8. In the Listening Ports section, create the default port by clicking Add. The Port Info dialog opens. Note: You must specify the default port.
    • Enter the Port. For instance, 9081.
    • Choose http for the Connection Protocol.
    • Click OK. The HTTP port with the default identifier appears in the list of Listening ports.

      Default HTTP port
  9. Create the port with the server/data/rules/deploy identifier by clicking Add.
    • Enter server/data/rules/deploy for the ID.
    • Enter the same port value as you did for the default port. For instance, 9081.
    • Select http for the Connection Protocol.
    • Click OK. The HTTP port with server/data/rules/deploy ID appears in the list of Listening ports.
  10. Optionally, you can add a secure listening port for authenticated users, secured connections, and secure chat. Click Add.The Port Info dialog opens.
    • Enter https for the ID field. This specific ID is required in GWE 8.5.
    • Enter the Port. For instance, 9443.
    • Enter https for the Connection Protocol.
    • Choose Secured for the Listening Mode.
    • Click OK.

  11. Ensure the Working Directory and Command Line fields contain "." (period).

    Commands
  12. Click Save.
  13. The Confirmation dialog for changing the application's port opens. Click Yes.
  14. Important: Genesys recommends that you use external Cassandra, which you can configure by following these instructions. However, embedded Cassandra can be a better choice for a lab installation.
    Important: Starting in 8.5.0, Embedded Cassandra mode is deprecated in Web Engagement; support for this mode will be discontinued in 9.0.
    To configure embedded Cassandra, select the Options tab and complete these steps:
    1. Make sure the the enabled option in the [cassandraEmbedded] section is set to true.
    2. Set the clusterName option in the [cassandraEmbedded] section to the name of your Cassandra cluster, which must not contain spaces. For example, My_Cassandra_Cluster.
    3. In the [cassandraEmbedded] section, you can take the default values for all of the options except seedNodes, which requires a comma-separated list of seed nodes, where each seed node is represented by an IP address or fully qualified domain name (FQDN). You must select your seed nodes from one or more of the nodes where Web Engagement Servers are deployed. For more information, see the description of the seedNodes option. Here are two examples of seed node lists:
      • 192.168.0.1,192.168.0.3
      • host1.mydomain.com,host2.mydomain.com.
    4. Make sure that the replicationStrategy option in the [cassandraKeyspace] section is set to NetworkTopologyStrategy.
    5. Make sure that the replicationStrategyParams option in the [cassandraKeyspace] section is specified in accordance with the configuration of your Cassandra cluster.
    6. Edit Web Engagement installation directory/server/resources/cassandra-rackdc.properties.
    7. Edit Web Engagement installation directory/server/resources/es-index.properties.
    8. Verify that the required communication ports are opened.
  15. Click Save & Close. If the Confirmation dialog opens, click Yes.

Configuring a Connection to a Cluster of Chat Servers (Optional)

Note: If you are running Web Engagement in a production environment, Genesys recommends connecting the Web Engagement Cluster to a cluster of Chat Servers rather than to a single instance of Chat Server.


Complete the steps below to configure a cluster of Chat servers for the Cluster.

Start

  1. In Genesys Administrator, create an application with a type of Application Cluster. This example uses an Application Cluster app called Chat Cluster.
  2. Navigate to Provisioning > Environment > Applications, select your Cluster application, and click Edit.
  3. In the Connections section, add a connection to Solution Control Server and an Application Cluster application that has connections to one or more Chat servers.

    The Cluster has a connection to the ChatCluster Application Cluster application.
  4. Click Save & Close
  5. Open your Application Cluster application.
  6. In the Connections section, add connections to one or more Chat Servers, using a port ID of webapi for each connection.

    The ChatCluster application has connections to two Chat servers.
  7. Click Save & Close.

End

End

Adding Nodes to a Cluster

Prerequisites

You completed:

Note: A single-node configuration works well in a lab environment, but in production, you need more than one node, in order to provide high availability. And every time you establish a new node, you must complete the following steps in order to create and configure it.


Start

  1. Follow the instructions above for Creating a Node Application, but use a different name for the new node.
  2. Configure the new node application, as shown above, but point to a different server address.

End


Important: If you use more than one node, you need to set up Load Balancing in your environment.
