Install the Harvester on a Linux Server

A two-tier distributed deployment of CA Network Flow Analysis may include one or more Linux Harvester servers. To install the Harvester software on a dedicated Linux server or virtual machine, complete the steps in this topic.

Follow these steps:

1. Verify that the server is prepared as described in Prepare the Linux Servers.
2. Log in to the Harvester server as root.

   You can install the software locally or remotely--for example, by using ssh when you are logged in with root privileges.

   Note: If you do not have root access, use an account with sudo privileges.

3. Open a command prompt window.
4. Run the following command to change the ulimit for the open files limit:

   ulimit -n ulimit_number
   

   Example:

   ulimit -n 65536
   

5. Prepare the installation/upgrade file for execution:
   1. Log in to the Harvester server as root.

      You can install or upgrade the software locally or remotely--for example, by using ssh when you are logged in with root privileges. If you do not have root access, use an account with sudo privileges.

   2. Execute the chmod command on the file in a terminal window:

      chmod u+x NFHarvesterSetup9.2.1.bin
      

   3. (Optional) Execute the list command to verify that the file is executable:

      ls -al
      

      The file permission settings are displayed.

6. Run the installation or upgrade software:

   ./NFHarvesterSetup9.2.1.bin

   The language selection screen opens.

7. Verify that the appropriate language is selected, then click OK.

   The Welcome screen opens.

8. Click Next in the Welcome screen.

   The License Agreement screen opens.

9. Review and accept the license agreement:
   1. Read the license agreement and scroll down.
   2. If you want to continue under the terms of the license agreement, click the option to accept it. This option is activated when you scroll to the bottom.
   3. Click Next.

      Prerequisite tests are run to identify problems on the server. If a problem is found, an error message opens, as described in Troubleshooting.

10. If the Pre-requisite Check Warning message opens, review the test results:
    1. Correct problems now or wait until the program finishes. For more information about the warnings, see the Troubleshooting section.
    2. Click OK to close the message.

       Once the server passes the required checks and you close any noncritical messages, the Choose Install Folder screen opens and displays the default root installation path.

11. Verify or specify the installation directory:
    1. (Optional) Click Choose in the Choose Install Folder screen to change the installation location.

       We recommend that you install CA Network Flow Analysis components on a partition that is dedicated to CA Network Flow Analysis. The NFA console will be installed to the same directory that you choose for the Harvester.

    2. Click Next when the installation path setting is correct.

       The Pre-Installation Summary screen opens.

12. Review the pre-installation information, then click Install.

    The Installing Harvester screen opens, which shows the progress. When the installation is complete, the Install Complete screen opens and reports any errors that occurred.

13. (Optional) If errors occurred during the installation, see the following log for details:

    <install_path>/Harvester_Install_<timestamp>.log (where <timestamp is the time the log was created)

14. Click Done in the Install Complete screen.

    The Harvester installation program closes.

Next: Repeat these steps to install a Harvester on another server or install the console.
