Choosing Components to Install
------------------------------

To install |product_name| on a server, you need to choose a component to install on the |product_name| screen:

The following options are available:

- **Management Panel.** Install the web-based user interface for managing |product_name| clusters.

- **Storage.** Turn the server into a node ready to run |product_name| services related to data storage.

- **Management Panel and Storage.** Install both above components at once.

You will need to install **Management Panel** or **Management Panel and Storage** on the first server and **Storage** on all other servers. The detailed instructions are provided in the following sections.

.. note:: The management panel will be installed on the system disk.

.. _Choosing Components to Install on the First Server:

Choosing Components to Install on the First Server
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

On the first server, you will need to install the management panel (with or without storage, as per your plan).

Do the following on the |product_name_bold| screen:

#. Choose **Management Panel** or **Management Panel and Storage**.

#. In the **Management Panel network** drop-down list, select a network interface that will provide access to the management panel.

#. In the **Management network** drop-down list, select a network interface and specify a port for internal management and configuration purposes (the port 8888 is used by default).

#. Create a password for the ``admin`` account of the management panel and confirm it in the corresponding fields.

#. Click **Done**.

After completing the steps above, proceed to :ref:`Selecting Destination Partition`.

.. _Choosing Components to Install on the Second and Other Servers:

Choosing Components to Install on the Second and Other Servers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

On the second and other servers, you will need to install the **Storage** component only. Such servers will run services related to data storage and will be added to the |product_name| infrastructure during installation.

For security reasons, you will need to provide a token that can only be obtained from the management panel you have installed on the first server. A single token can be used to install the storage component on multiple servers in parallel.

To obtain a token:

#. Log in to the |product_name| management panel. On any computer with access to the management panel network, open a web browser and visit the management node IP address on port 8888: https://<management_node_IP_address>:8888. If prompted, add the security certificate to browser's exceptions.

#. In the management panel:

   - If you only installed the management component on the first server, you will see the welcome screen where a token will be shown (you can generate a new one if needed; generating a new token invalidates the old one).

   - If you installed both the **Management** and **Storage** components on the first server, you will see the **NODES** screen where the only node will be shown in the **UNASSIGNED** list.

   Click **ADD NODE** and a screen similar to open a screen similar to the welcome one. On it, a token will be shown (you can generate a new one if needed; generating a new token invalidates the old one).

Having obtained the token, do the following on the |product_name_bold| screen:

#. Choose **Storage**.

#. In the **Management node** field, specify the IP address of the node with the management panel.

#. In the **Token** field, specify the acquired token.

#. Click **Done** and proceed to :ref:`Selecting Destination Partition`.
