Installing a master server

If you install the product on distributed servers, you must install core software, including the parse and index services and the administration console on one computer, which is known as the master server. You can then install additional servers to support crawling, indexing, and search and to provide failover support for these activities.

About this task

After you install the software on this computer, you must add a crawler server and at least one search server.

Procedure

To install the master server for a multiple server installation by using the graphical installation program:

  1. From the product DVD or electronic distribution image, extract the files in the .zip file or .tar file for your operating system and run the appropriate command:
    Option Description
    AIX® or Linux®
    1. Enter: ./install.bin
    2. To view information about prerequisites or any known issues before you install the product, click Prerequisite Information or Release Information.
    3. Click Install Product and then click the action to launch the installation program.
    Windows
    1. Double-click the install.exe file or enter install.exe in a command window.
    2. To view information about prerequisites or any known issues before you install the product, click Prerequisite Information or Release Information.
    3. Click Install Product and then click the action to launch the installation program.
  2. Follow the instructions in the installation program.
    When you specify installation options:
    1. Verify the fully qualified host name of this computer.
      You cannot specify an IPv6 address as the host name of the server.
    2. Accept or change the user name and password for the default Watson Explorer Content Analytics administrator. The administrator ID and password must be the same on all servers.

      To administer the Watson Explorer Content Analytics system, you log in as the master administrator with this user name and password. The default value is esadmin. If you log in with a non-root user ID to start the installation program, you cannot change the user name and you cannot select the check box to create the user. To specify a domain user, use the format username@domain name. The domain user cannot be created by the installation program.

      If you plan to use WebSphere® Application Server instead of the embedded web application server, specify the user name for an administrative user who is registered in the LDAP server registry. Authentication for all administrative and application users that you add to the system is handled through WebSphere Application Server global security.

    3. For the server type, select Master: Distributed server.
  3. Click Install to use the default settings for all other installation options and start installing the software.
  4. Optional: If you want to change the default settings, click Advanced Options instead of clicking Install.
    If you plan to use WebSphere Application Server instead of the embedded web application server, you must click Advanced Options to specify information about your WebSphere Application Server installation.
    1. Use the following guidelines when you specify installation options:
      • On AIX or Linux, if you do not accept the default paths for the installation and data directories, ensure that the paths that you specify do not contain spaces in the path names.
      • Ensure that the default ports do not conflict with any ports that are already assigned to other applications on this computer.
      • If you select the option to use WebSphere Application Server and global security is enabled, you must specify the WebSphere Application Server administrative user name and password.
    2. On the summary page, review the options that you selected and click Install to start installing the software.
  5. On Windows, after the software is installed, restart the computer and log in as the Watson Explorer Content Analytics administrative user before you start Watson Explorer Content Analytics.

    On Windows Server 2008, click Start > All Programs > IBM® Watson Explorer Content Analytics > Start up.

  6. Optional: Verify the installation by running the First Steps program and clicking Start Server. After the server is started, click Verify Installation.
    When you log in as the administrative user, the First Steps program is started automatically.
