Install Splunk Phantom on a system with limited internet access

Use a tar file to install Splunk Phantom without an internet connection.

Prerequisites

Contact Phantom support to get this installation file. You can open a support case at Splunk Support and Services or by calling +1(855)SPLUNK-S or +1(855)775-8657. International Splunk Support numbers are found in the Contact Us section of the Splunk website.

Supported operating systems for this method:

• Red Hat Enterprise Linux 7.6 through 7.9
• CentOS 7.6 through 7.9

On Red Hat Enterprise Linux, you must either create a satellite server or local YUM repository for operating system packages and other dependencies. See the Red Hat Knowledgebase article How can we regularly update a disconnected system (A system without internet connection)?

Operating System	Repositories
CentOS 7.6 through 7.9	os updates
Red Hat Enterprise Linux 7.6 through 7.9	rhel-7-server-rpms rhel-7-server-optional-rpms rhel-server-rhscl-7-rpms
Red Hat Enterprise Linux on AWS	rhui-<region>-rhel-server-optional

Update the operating system and dependencies

Do these tasks with root permissions, either by logging in as root or as a user with sudo permission.

1. Contact Splunk Phantom Support to get access to the offline installer tar file. Once access has been granted, you can download the file from the Splunk Phantom community website.
2. Clear YUM's caches.
   yum clean all
3. Update the operating system and all installed packages.
   yum update
4. Restart the operating system.
   shutdown -r now

Install Splunk Phantom from the tar file

1. Make a directory for the tar file.
   mkdir /usr/local/src/upgrade-<version>
2. Change to the created directory.
   cd /usr/local/src/upgrade-<version>
3. Download or copy the tar file to the directory.
4. Extract the tar file.
   tar -xvzf phantom_offline_setup_<OS>-<version>.tgz
5. Change to the directory phantom_offline_setup:
   cd phantom_offline_setup_<OS><version>
6. Run the installation script.
   ./phantom_offline_setup_<OS>.sh install

   To install without apps, add --without-apps to the command:

   ./phantom_offline_setup_<OS>.sh install --without-apps

Next step: log in to verify the installation

You can log in to the Splunk Phantom web interface after the setup script completes to configure user accounts and additional settings. See Log in to the Splunk Phantom web interface.
