15.2 Installing the Vibe Software on Multiple Servers

  1. Update your existing Novell Vibe server to participate in a multi-server configuration:

    1. Stop Vibe.

    2. Start the Vibe Installation program.

      For information on how to start the installation program, see Section 4.1.3, Running the Linux Vibe Installation Program or Section 4.2.2, Running the Windows Vibe Installation Program.

    3. On the Installation Settings page, select Reconfigure Settings, then click Next.

    4. On the Choose Installation Type page, select Advanced, then click Next.

    5. Click Next to proceed through the installation pages where no changes are needed.

    6. (Conditional) If you do not have the Basic Vibe Installation Summary Sheet and Advanced Vibe Installation Summary Sheet from the initial Vibe server installation, record the configuration of the initial Vibe server as you proceed through the installation pages.

      Subsequent Vibe servers in the multi-server configuration must be installed with the same configuration settings as the initial Vibe server.

    7. On the Vibe Cluster Configuration page, specify the following information:

      Enable clustered environment: Select this option to enable your environment for a multi-server configuration.

      Selecting this option configures Ehcache for your Vibe cluster.

      Network interface for distributed cache service: Specify the IP address or hostname of the distributed cache service.

      Multicast Group Address: (Optional) Specify the common multicast group IP address. Each clustered node recognizes other nodes in the cluster by means of this IP address.

      IMPORTANT:Make sure you specify the same IP address on all Vibe nodes in the cluster. After you have set this IP address for each Vibe node, restart each node in succession, allowing each node to initialize before restarting the next.

      The default multicast group IP address is 232.0.0.1. If you have more than one clustered Vibe system (for example, one in the lab and one in production), or if you have another software product that is already using the default multicast group IP address, you must update this field for one installation so that it uses an IP address other than the default.

      Use an IP address in the range of 224.0.0.1 to 239.255.255.255.

      Multicast Group Port: (Optional) Specify the port number through which the Vibe nodes will communicate.

    8. On the Ready to Install page, click Install.

    9. On the Installation Complete page, click Finish.

  2. Install the Vibe software on each additional server, using the same installation settings that you used for the initial Vibe server.

  3. On each Linux server where you installed the Vibe software, set the multicast route to enable the servers to function as a cluster:

    1. Use the following command on the command line to immediately set the multicast route for the server:

      route add -net 232.0.0.0/8 dev eth0

    2. To run this command each time the server reboots, add the command to the following file on each server:

      /etc/init.d/boot.local

  4. Start Vibe on each server, as described for the platform where you are installing Vibe:

  5. Continue with Configuring a Web Application to Provide High Availability Functionality for Your Vibe Site.
