# Install Cortex XSOAR Offline

Install Cortex XSOAR 6.15 without internet access.

You need to download the required Cortex XSOAR dependencies, installer, license files, and Docker images from an internet-connected machine. Then transfer the files to the offline server and install the dependencies, Cortex XSOAR, and Docker images.

If you are deploying a signed installer:

* You need to import the public key into the operating system. Open a [ticket](https://support.paloaltonetworks.com/Support/Index) with Palo Alto Networks support to get the public key. It is valid for six months.
* If you are using engines or hosts in a multi-tenant environment, you need to install `makeself`.

{% hint style="info" %}

* Download the latest dependencies for your Cortex XSOAR release before installation. Dependencies can change between releases.
* The steps vary by operating system.
* Docker/Podman runs Python scripts in an isolated container.
* After installation, you need to [Add a License](/cortex-xsoar-6-installation-guides/6.15/cortex-xsoar-installation-guide/post-installation-checklist/add-a-license.md).
  {% endhint %}

### Prerequisites for installing Cortex XSOAR

Verify the following requirements before you install Cortex XSOAR:

* You have a Customer Support Portal account.

  Set up your account. For more information, see [How to Create Your CSP User Account](https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClNVCA0).

{% step %}

### Download the required dependencies

1. On a machine with internet access, download the [Dependencies for Offline Installation](/cortex-xsoar-6-installation-guides/6.15/cortex-xsoar-installation-guide/single-server-installation/install-cortex-xsoar-offline/dependencies-for-offline-installation.md) for your deployment type.
   * **Ubuntu/Debian:** Run `sudo apt-get install --download-only <package>`, which saves the package and its dependencies in `/var/cache/apt/archives`.

     If the latest package version is already installed, run `sudo apt-get download <package>`. The command saves the package in your current directory. You can also use `sudo apt-get download` on Ubuntu.
   * **RHEL/Rocky/Oracle/Amazon:** Run `sudo yumdownloader --resolve <package>` or `sudo yum install --downloadonly <package>`.
2. Copy all `.deb` files to a folder on the offline machine.
   {% endstep %}

{% step %}

### Download the installation files

On a machine with internet access, do the following:

1. Log in to [Cortex Gateway](https://cortex-gateway.paloaltonetworks.com/accounts).
2. Locate the activation card for your license.

   By default, the **Production-Standalone** license is selected. You can also select **Dev**. To use production and development tenants with a private remote repository, select **Dev**. You can install a development tenant later.
3. Select **Download On Prem**.
4. Select **Next**.
5. Under **Choose Download Option**, select **Installer**.
6. Select the checkbox to agree to the license terms and conditions. Then select **Download**.

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p>In Google Chrome, configure <strong>Settings</strong> → <strong>Privacy and security</strong> → <strong>Site settings</strong> → <strong>Additional permissions</strong> → <strong>Automatic downloads</strong>. Select <strong>Sites can ask to automatically download multiple files</strong>.</p></div>

   The installer file, `demistoserver-xxxxx.sh`, and a zipped JSON license file download.

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p>Copy the download link from your browser's <strong>Downloads</strong> section. The link contains the token needed for downloading Docker images.</p></div>
7. If you use a signed installer, import the provided GPG public key. Open a [support ticket](https://support.paloaltonetworks.com/Support/Index) to get the public key.

   For example, run `rpm --import public.key` to import the key into the local GPG keyring. Follow the requirements for your operating system.
8. If you use a signed installer, install `makeself` when required. For example, run `yum install makeself`.
   {% endstep %}

{% step %}

### Download Docker images

The Cortex XSOAR installer sets up Docker automatically. It does not include the images required to run integrations. On a machine with internet access, use one of the following methods:

* **Targeted download (recommended):** Use the `download_packs_and_docker_images.py` script to download Docker images for the content pack integrations you plan to use, such as AWS-ILM, Cybereason, and EWS.

  The script is in the `Utils` folder in the Git content repository. If you cannot access the repository, download the script [here](https://raw.githubusercontent.com/demisto/content/master/Utils/download_packs_and_docker_images.py). For details, see [download packs offline](https://xsoar.pan.dev/docs/reference/articles/download-packs-offline).
* **Full library download:** Append `downloadName=dockerimages` to the installer download URL. For example, `https://download.demisto.com/download-params?token=xxxxxxx email=user@paloaltonetworks.com downloadName=dockerimages eula=accept`.

  The Docker images file is approximately 75 GB.
  {% endstep %}

{% step %}

### Transfer and verify downloaded files

1. Transfer the files downloaded in steps 1 to 3 to the offline machine.
2. Install all dependencies:
   * **Ubuntu/Debian:** `sudo dpkg -i *`
   * **RHEL/Rocky/Oracle/Amazon Linux:** `sudo yum localinstall *`
     {% endstep %}

{% step %}

### Install Cortex XSOAR

The Cortex XSOAR shell installer automatically installs and configures the container runtime using the dependencies you installed in the previous step.

{% hint style="warning" %}
For Oracle Linux and Amazon Linux 2, install Docker before running the installer.
{% endhint %}

Run the following commands:

* `chmod +x demisto.sh`
* `sudo ./demisto.sh -- -tools=false -do-not-start-server=true`

  For multi-tenant deployments, also include the `-multi-tenant` flag.
  {% endstep %}

{% step %}

### Load Docker images

* **Ubuntu, Oracle, and Amazon Linux 2/2023 (Docker):** Run `sudo docker load -i <YOUR_DOCKER_FILE>.tar`.
* **Red Hat v8+ and Rocky Linux 9+ (Podman):** Do the following:
  1. Ensure the file is owned by the `demisto` user: `sudo chown demisto:demisto <FILENAME>.tar`.
  2. Ensure that you are in the root directory: `cd /`.
  3. Run `sudo -su demisto podman load -i <PATH TO FILE>/<FILENAME>.tar`.
  4. To verify that images can run, use `podman images`. To validate specific images and identify issues, use `podman images -q "demisto/python:1.3-alpine"`.
     {% endstep %}

{% step %}

### Start Cortex XSOAR

Run the following command:

`sudo systemctl start demisto`
{% endstep %}

{% step %}

### Verify the installation

1. Confirm that the Cortex XSOAR server status is active. Run `systemctl status demisto`.
2. For Ubuntu, Oracle, and Amazon Linux 2/2023, confirm that the Docker service status is active. Run `systemctl status docker`.
3. In a web browser, go to `https://serverURL:port` to verify that Cortex XSOAR was successfully installed.

   When you open Cortex XSOAR for the first time, add the license.
   {% endstep %}
   {% endstepper %}

### Troubleshoot offline installation

If you receive the following message, ensure that you use a version of Podman that supports archives with multiple images.

`Error: error pulling "": unable to pull dir:./xsoar_docker_images.tar: error determining pull goal for image "dir:./xsoar_docker_images.tar": error parsing dest reference name "localhost/./xsoar_docker_images.tar": error parsing named reference "localhost/./xsoar_docker_images.tar": invalid reference format`

### Next steps

After you successfully complete your Cortex XSOAR offline installation, you might need to:

* Turn off Marketplace synchronization.
* Download content packs offline.

  For more information, see [Download Content Packs and Docker Images Offline](https://xsoar.pan.dev/docs/reference/articles/download-packs-offline).

  Watch this video for information about installing content in an air-gapped environment: [Install XSOAR Content in Air-Gapped Environments](https://www.youtube.com/watch?v=sTvSUFeZI3I).
* Do custom configuration for your use case, such as customizing playbooks, sub-playbooks, or custom indicators.
* Install an engine offline.
* Set relevant server configurations.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsoar-6-installation-guides/6.15/cortex-xsoar-installation-guide/single-server-installation/install-cortex-xsoar-offline.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
