9.2. Installing the headless Decision Manager controller

You can install the headless Decision Manager controller and use the REST API or the KIE Server Java Client API to interact with it.

Prerequisites

  • A backed-up Red Hat JBoss EAP installation version 7.3 is available. The base directory of the Red Hat JBoss EAP installation is referred to as EAP_HOME.
  • Sufficient user permissions to complete the installation are granted.

Procedure

  1. Navigate to the Software Downloads page in the Red Hat Customer Portal (login required), and select the product and version from the drop-down options:

    • Product: Decision Manager
    • Version: 7.10
  2. Download Red Hat Decision Manager 7.10.0 Add Ons (the rhdm-7.10.0-add-ons.zip file).
  3. Extract the rhdm-7.10.0-add-ons.zip file. The rhdm-7.10.0-controller-ee7.zip file is in the extracted directory.
  4. Extract the rhdm-7.10.0-controller-ee7 archive to a temporary directory. In the following examples this directory is called TEMP_DIR.

  5. Copy the TEMP_DIR/rhdm-7.10.0-controller-ee7/controller.war directory to EAP_HOME/standalone/deployments/.

    警告

    Ensure that the names of the headless Decision Manager controller deployments you copy do not conflict with your existing deployments in the Red Hat JBoss EAP instance.

  6. Copy the contents of the TEMP_DIR/rhdm-7.10.0-controller-ee7/SecurityPolicy/ directory to EAP_HOME/bin.
  7. When prompted to overwrite files, select Yes.
  8. In the EAP_HOME/standalone/deployments/ directory, create an empty file named controller.war.dodeploy. This file ensures that the headless Decision Manager controller is automatically deployed when the server starts.

9.2.1. Creating a headless Decision Manager controller user
リンクのコピー

Before you can use the headless Decision Manager controller, you must create a user that has the kie-server role.

Prerequisites

  • The headless Decision Manager controller is installed in the base directory of the Red Hat JBoss EAP installation (EAP_HOME).

Procedure

  1. In a terminal application, navigate to the EAP_HOME/bin directory.

  2. Enter the following command and replace <USER_NAME> and <PASSWORD> with the user name and password of your choice. 

    $ ./add-user.sh -a --user <username> --password <password> --role kie-server
    注記

    Make sure that the specified user name is not the same as an existing user, role, or group. For example, do not create a user with the user name admin.

    The password must have at least eight characters and must contain at least one number and one non-alphanumeric character, but not & (ampersand).

  3. Make a note of your user name and password.

9.2.2. Configuring KIE Server and the headless Decision Manager controller
リンクのコピー

If KIE Server will be managed by the headless Decision Manager controller, you must edit the standalone-full.xml file in KIE Server installation and the standalone.xml file in the headless Decision Manager controller installation.

Prerequisites

  • KIE Server is installed in an EAP_HOME.

  • The headless Decision Manager controller is installed in an EAP_HOME.

    注記

    You should install KIE Server and the headless Decision Manager controller on different servers in production environments. However, if you install KIE Server and the headless Decision Manager controller on the same server, for example in a development environment, make these changes in the shared standalone-full.xml file.

  • On KIE Server nodes, a user with the kie-server role exists.

  • On the server nodes, a user with the kie-server role exists.

    Procedure

    1. In the EAP_HOME/standalone/configuration/standalone-full.xml file, add the following properties to the <system-properties> section and replace <USERNAME> and <USER_PWD> with the credentials of a user with the kie-server role: 

         <property name="org.kie.server.user" value="<USERNAME>"/>
   <property name="org.kie.server.pwd" value="<USER_PWD>"/>

    2. In the KIE Server EAP_HOME/standalone/configuration/standalone-full.xml file, add the following properties to the <system-properties> section: 

        <property name="org.kie.server.controller.user" value="<CONTROLLER_USER>"/>
  <property name="org.kie.server.controller.pwd" value="<CONTROLLER_PWD>"/>
  <property name="org.kie.server.id" value="<KIE_SERVER_ID>"/>
  <property name="org.kie.server.location" value="http://<HOST>:<PORT>/kie-server/services/rest/server"/>
  <property name="org.kie.server.controller" value="<CONTROLLER_URL>"/>
    3. In this file, replace the following values:
  • Replace <CONTROLLER_USER> and <CONTROLLER_PWD> with the credentials of a user with the kie-server role.
  • Replace <KIE_SERVER_ID> with the ID or name of the KIE Server installation, for example, rhdm-7.10.0-kie-server-1.
  • Replace <HOST> with the ID or name of the KIE Server host, for example, localhost or 192.7.8.9.

  • Replace <PORT> with the port of the KIE Server host, for example, 8080.

    注記

    The org.kie.server.location property specifies the location of KIE Server.

  • Replace <CONTROLLER_URL> with the URL of the headless Decision Manager controller. KIE Server connects to this URL during startup.
