Add additional host

Use this procedure to add another host to the grid. By adding a new host to the grid, applications may scale out to this new host or new applications may be installed there.

Service User Requirements:

  • Windows: local or domain account with the ability to log on and run as a service with CRUD access to the file system where the grid will be installed

  • Linux: local service account with CRUD access to the file system where the grid will be installed

  1. In the Configuration Manager, click the Grid Configuration link.
  2. Click the Hosts link.
  3. Click Add Host.
  4. Enter the following information:
    Host FQDN

    The fully qualified domain name (FQDN) for the host.

    Host Name

    A name for the host (optional). This is an alias used to identify the host within the grid. By default, the FQDN will be truncated and the first part will become the host name.

    Agent Port

    Change the agent port if required. Note that the same port will be suggested as used on the primary (registry) host. Verify that this port is free on the new host and, if it is not, select an alternative port.

    Initial State

    Change the initial state if required. The default is true, which means that when the bootstrap installer package is executed on the new host, it will immediately start the grid on that host.

    Set as Secondary Registry Host

    Change the "Set as Secondary Registry Host" if required. The default is true if there is not currently a secondary registry configured within the grid. See Configure Secondary Registry Host in LifeCycle Manager if Grid is administered through LCM.

    Applications

    Change the applications if required. All applications which can be auto-scaled to new hosts will appear in the list and if chosen by the developer they will be automatically selected.

  5. Click OK.
  6. Download the bootstrap installation package by clicking on the save symbol. If you do not carry out this process from the new host directly, transfer the package to the new host.
    Note: The bootstrap installation package contains keystore and keystore password files which permit access to the Grid. Care should be taken to ensure that the bootstrap package integrity is maintained and that it is removed from the file system following installation of the additional host(s).
  7. Execute the package and follow the prompts.
