14.2 Performing a Silent Installation

The silent or unattended installation is useful if you need to install more than one Sentinel server, Collector Manager, or Correlation Engine in your deployment. You can record the installation parameters during the interactive installation and then run the recorded files on other systems.

NOTE:For Collector Manager and Correlation Engine, use the configuration file to connect Collector Manager and Correlation Engine to a different Sentinel server than the one recorded in the response file. Update this file with the relevant Sentinel server details and use it along with the response file during unattended installation.

To enable FIPS 140-2 mode, ensure that the response file includes the following parameters:

  • ENABLE_FIPS_MODE

  • NSS_DB_PASSWORD

To perform a silent installation:

  1. Download the installation files from the Downloads website.

  2. Log in as root to the server where you want to install Sentinel or Collector manager or Correlation engine.

  3. Specify the following command to extract the install files from the tar file:

    tar -zxvf <install_filename>

    Replace <install_filename> with the actual name of the install file.

  4. (Conditional) To install Sentinel server in silent mode, specify the following command:

    ./install-sentinel -u <response_filename>

    The installation proceeds with the values stored in the response file.

    If you installed a Sentinel server, it might take few minutes for all services to start after installation, because the system performs a one-time initialization. Wait until the installation finishes before you log in to the server.

  5. (Conditional) To install Collector Managers, specify the following command:

    • To use the response file:

      ./install-cm -u <response_filename>
    • To use the response file and the configuration file:

      ./install-cm -u <response_filename> -i <configuration_filename>
  6. (Conditional) To install Correlation Engines, specify the following command:

    • To use the response file:

      ./install-ce -u <response_file>
    • To use the response file and the configuration file:

      ./install-ce -u <response_filename> -i <configuration_filename>
  7. (Conditional) If you chose to enable FIPS 140-2 mode for the Sentinel server, complete the FIPS 140-2 mode configuration by following the tasks mentioned in Section 24.0, Operating Sentinel in FIPS 140-2 Mode.
