JSA Software only Installations

A software only installation is a JSA installation on your hardware that uses an RHEL operating system that you provide. You must configure partitions and perform other RHEL preparation before a JSA software only installation.

Important

  • Ensure that your hardware meets the system requirements for JSA deployments.

  • Install no software other than JSA and RHEL on your hardware. Unapproved RPM installations can cause dependency errors when you upgrade JSA software and can also cause performance issues in your deployment.

  • Do not update your operating system or packages before or after JSA installation.

  • It is not possible to do a factory reset from the recovery partition when you do a software only installation.

  • If you are installing JSA on a Unified Extensible Firmware Interface (UEFI) system, secure boot must be disabled.

Complete the following tasks in order:

Prerequisites for Installing JSA on Your Hardware

Hardware

See the tables below for memory, processor, and storage requirements.

Memory and CPU Requirements

If you use hardware not provided by Juniper, ensure that your hardware meets or exceeds the specifications for memory and CPU of the corresponding JSA appliance.

Note:

You can change the memory or the CPU of your appliance by shutting down the appliance and making the changes. When you restart the appliance the system detects the changes and adjusts the performance related configuration. You must maintain the minimum requirements.

Storage requirements

Your appliance must have at least 256 GB of storage available.

The following table shows the storage requirements for installing JSA on your hardware.

Note:

The minimum required storage size varies, based on factors such as event size, events per second (EPS), and retention requirements.

JSA Software node license comes with the default Red Hat entitlement. You can provide your own RHEL, or acquire entitlement to a JSA Software Node. For the vulnerability updates, you must purchase RHEL entitlement from the satellite server.

If there are circumstances where you need install to RHEL separately, proceed with the following instructions.

  1. Map the ISO to a device for your appliance by using the bootable USB flash drive with the ISO.

    For information about creating a bootable USB flash drive, see USB Flash Drive Installations.

  2. Insert the portable storage device into your appliance and restart your appliance.

  3. From the starting menu, do one of the following options:

    • Select the device that you mapped the ISO to, or the USB drive, as the boot option.

    • To install on a system that supports Extensible Firmware Interface (EFI), you must start the system in legacy mode.

  4. When prompted, log in to the system as the root user.

  5. Follow the instructions in the installation wizard to complete the installation:

    1. Set the language to English (US).

    2. Click Date & Time and set the time for your deployment.

    3. Click Software selection and select Minimal Install.

    4. Click Installation Destination and select the I will configure partitioning option.

    5. Select LVM from the list.

    6. Click the Add button to add the mount points and capacities for your partitions, and then click Done. For more information about RHEL7 partitions, see Linux Operating System Partition Properties for JSA Installations on Your Own System.

    7. Click Network & Host Name.

    8. Enter a fully qualified domain name for your appliance host name.

    9. Select the interface in the list, move the switch to the ON position, and click Configure.

    10. On the General tab, select Automatically connect to this network when it is available option.

    11. On the IPv4 Settings tab, select Manual in the Method list.

    12. Click Add to enter the IP address, Netmask, and Gateway for the appliance in the Addresses field.

    13. Add two DNS servers.

    14. Click Save > Done > Begin Installation.

  6. Set the root password, and then click Finish configuration.

  7. After the installation is complete, disable SELinux by modifying the /etc/selinux/config file, and restart the appliance.

    To modify the /etc/selinux/config file, complete the following steps:

    1. Open the /etc/selinux/config file using the following command:

    2. Configure the SELINUX=disabled option:

    3. Save the file and restart the appliance.

Linux Operating System Partition Properties for JSA Installations on Your Own System

If you use your own disk drive hardware, you can delete and re-create partitions on your Red Hat Enterprise Linux operating system rather than modify the default partitions.

Use the values in the following table as a guide when you re-create the partitioning on your Red hat Enterprise Linux Operating system. You must use these partition names. Using other partition names can cause the installation to fail and other issues.

The file system for each partition is XFS.

Installing JSA After the RHEL Installation

Install JSA on your own device after you install RHEL.

A fresh software install erases all data in /store as part of the installation process. If you want to preserve the contents of /store when performing a software install, manually back up the data you want to preserve apart from the host where the software is to be installed.

  1. Copy the JSA ISO to /root or /storetmp directory of the device.

  2. Create the /media/cdrom/ directory by typing the following command:

    mkdir /media/cdrom

  3. Mount the JSA ISO by using the following command:

    mount - o loop <path_to_iso>/<qradar.iso> / media/cdrom

  4. Run the JSA setup by using the following command:

    /media/cdrom/setup

    Note:

    A new kernel might be installed as part of the installation, which requires a system restart. Repeat the commands in steps 3 and 4 after the system restart to continue the installation.

  5. Select the disk drive type:

    Note:

    The software installation menu will not be visible in the installation wizard by default.

    • Software Install

    • High Availability Appliance

  6. Select the disk drive assignment, and then select Next.

  7. If you selected an disk drive for high-availability (HA), select whether the disk drive is a console.

  8. For the type of setup, select Normal Setup (default) or HA Recovery Setup, and set up the time.

  9. If you selected HA Recovery Setup, enter the cluster virtual IP address.

  10. Select the Internet Protocol version.

  11. If you selected ipv6, select manual or auto for the Configuration type.

  12. Select the bonded interface setup, if required.

  13. Select the management interface.

  14. In the wizard, enter a fully qualified domain name in the Hostname field.

    Note:

    The hostname must not contain only numbers.

  15. In the IP address field, enter a static IP address, or use the assigned IP address.

    Note:

    If you are configuring this host as primary host for a high availability (HA) cluster, and you selected Yes for auto-configure, you must record the automatically-generated IP address. The generated IP address is entered during HA configuration.

    For more information, see Juniper Security Analytics High Availability Guide.

  16. If you do not have a email server, enter localhost in the Email server name field.

  17. If you are installing a Console, enter an admin password that meets the following criteria:

    • Contains at least 5 characters

    • Contains no spaces

    • Can include the following special characters: @, #, ^, and *.

  18. Leave the root password as it is.

  19. Click Finish.
