Install Cortex XSOAR on your VM Ensure the following DNS records were added to your DNS server to resolve hostnames to the cluster IP address (only static, DHCP is not supported). These DNS records (for a given tenant) should all point to the same cluster IP address to ensure a single entry point. For MSSP, each tenant must have its own set of **`xsoar.*`**, **`api-*`**, and **`ext-*`** FQDNs pointing to the tenant cluster's single entry point. * **`xsoar..`**: The Cortex XSOAR DNS name for accessing the UI. For example, **`xsoar.mycompany.com`**. * **`api-.`**: The Cortex XSOAR DNS name that is mapped for API access. For example, **`api-xsoar.mycompany.com`**. This should be a CNAME entry pointing to the same cluster IP address. * **`ext-.`**: The Cortex XSOAR DNS name that is mapped to access long running integrations. For example, **`ext-xsoar.mycompany.com`**. This should be a CNAME entry pointing to the same cluster IP address. 1. From the textual UI menu, select Cluster Installation. The virtual machine you use to run the installer will deploy Cortex XSOAR on all virtual machines in a cluster. For a single virtual machine (standalone), configure the settings for a single node. 2. Configure the following settings.

The IPs of all VMs (nodes) in a cluster must be on the same subnet, they currently cannot be split across subnets.

You can only change these field values in the textual UI menu before installing. To change these values after installing, you need to redeploy your cluster and then reinstall. Contact support or engineering for assistance.

| Field | Description | | -------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Cluster Nodes |

A list of IPs of all virtual machines/nodes in the cluster, separated by a space. For example, 10.196.37.10 10.196.37.11 10.196.37.12

Copy the IP of each VM from the Private IPv4 address in the OCI Instance information tab and paste it in this field, separated by a space.

| | Cluster FQDN |

The Cortex XSOAR environment DNS name. For example, \.\.\

Copy the FQDN from the Internal FQDN field in the OCI Instance information tab and paste it in this field.

For a single node: This field value must be registered in your DNS server so the FQDN will be resolved to the IP of the node.

Cortex XSOAR supports only static IP addresses for each virtual machine in the cluster, it does not support a DHCP (dynamic IP) network interface.

| | Installation Mode |

The tenant installation type. Options to select from are:

  • Enterprise (for non-multi-tenant installation, including production and development tenants)
  • (Multi-Tenant) Parent Tenant
  • (Multi-Tenant) Child Tenant
| | Cluster Region | The region the cluster is located in. For example, US. | | Cortex XSOAR Admin Email, Password, and Confirm Password |

Credentials for the first user to log in to Cortex XSOAR.

The password must be at least eight characters long and contain at least:

  • One lower case letter
  • One upper case letter
  • One number, or one of the following special characters: !@#%
| | Migration Mode | Relevant for migration from Cortex XSOAR 6. If checked, the migration wizard starts in the Cortex XSOAR 8 tenant. This cannot be changed at a later stage. | 3. Select Install. Verify all nodes meet the required hardware and network requirements, and select Install again. The virtual machine you use to run the installer will deploy Cortex XSOAR on all virtual machines in a cluster. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cortex-docs.paloaltonetworks.com/cortex-xsoar-8-on-prem/8.12/install-cortex-xsoar/install-cortex-xsoar-on-a-vm-deployed-on-oci/task-7.-install-cortex-xsoar-on-your-vm.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
