Linux: Preparing the Installation Manager

The IBM® Installation Manager is used to install installation packages such as IBM WebSphere® Portal and IBM WebSphere Application Server.

Prerequisites
Linux: Preparing your operating system

Procedure

If you have an existing Installation Manager, start it and go to File > Preferences. Then, click Updates. Click the Search for Installation Manager updates check box. This box enables the Installation Manager to search for updates the next time you run an installation or update.

If you do not have an existing Installation Manager, then complete the following procedure:

  1. Start all servers and applications that require a port number to avoid port conflicts when installing WebSphere Portal.
  2. Type ping yourserver.yourcompany.com on a command line to verify that your fully qualified host name is properly configured.
  3. Type ping localhost on a command line to verify that your network is properly configured.
  4. If you are installing on a server with a firewall, antivirus, screen saver, or desktop search engine that is enabled, disable them before you install. If you do not disable them and the installation program detects them, a warning message displays during the installation or the installation might fail.
  5. Optional: Complete the following steps to install as a non-root user:
    1. Log in to the operating system as the root user.
    2. Open a command line.
    3. Use the appropriate system commands to create the following items:
      • Non-root user, including password
      • Group
      • Directory, used when you install IBM Installation Manager and WebSphere Portal
    4. Set the user profile for the number of open files. Set the value to ulimit -n 10240.
    5. Add the non-root user to the new group.
    6. Run the following task to change the owner of the directory to the non-root user: 
      chown user:group /directory
    7. Run the following task to change permissions for the directory: 
      chmod 755 /directory
    8. Log in as the non-root user.
    9. Use the following command to install IBM Installation Manager: 
      ./userinst

      Set the IBM Installation Manager installation location to /directory/IBM/InstallationManager.

  6. Run the following task from the IIM directory: ./install
  7. Run the following task from the Portal Setup disk if you want to start the launchpad to complete all necessary installation steps: ./setup.sh
    Attention: The launchpad requires Firefox ESR 45 or earlier.
    Launchpad tip: On the Launchpad: Install Portal panel, you have the following options:
    Install IBM WebSphere Portal from media
    Choose this option if you are installing directly from the DVD.
    Install IBM WebSphere Portal from network
    Choose this option if you downloaded the electronic images.
    Install IBM Installation Manager only
    Choose this option if you want to install multiple IBM products, or if you want to install WebSphere Portal directly from IBM Passport Advantage, and a previous version of Installation Manager is not already installed on your system.
    Restriction: If you have a previously installed 32-bit version of Installation Manager, then you cannot proceed with this option. You must manually install the 64-bit version of Installation Manager that is specific to your operating system using the Setup disc before you proceed with the WebSphere Portal installation.
    Tip: Add the LaunchPadLocale language_code to the setup task to change the display to your user locale or to another language.
    Note: If the language is not currently supported for the user interface, you might see the English version. For details on supported languages and the language codes for all of the WebSphere Portal user interfaces, see Supported languages.

    After you complete all necessary steps from the launchpad, verify that your installation was successful.
