.. _video-worker-installer:

Additional ``findface-video-worker`` deployment on remote hosts
-------------------------------------------------------------------
	
To install only the ``findface-video-worker`` service, do the following:

.. tip::
   Be sure to consult the :ref:`system requirements <requirements>` prior.

.. tip::
   If you have several video cards on your server, see :ref:`video-cards` before deploying ``findface-video-worker-gpu``.

#. Download the installer file ``<findface-security-and-server-xxx>.run``.
#. Put the ``.run`` file into some directory on the designated host (for example, ``/home/username``).
#. From this directory, make the ``.run`` file executable.

   .. code::

      chmod +x <findface-security-and-server-xxx>.run

#. Execute the ``.run`` file.

   .. code::

      sudo ./<findface-security-and-server-xxx>.run

   The installer will ask you a few questions and perform several automated checks to ensure that the host meets the system requirements. Fill out the prompts appropriately once requested. The questions are the following:

   #. Product to install: FindFace Video Worker. 
   #. Type of ``findface-video-worker`` package: CPU or GPU.
   #. The IP address of the FindFace Enterprise Server host.

   After that, the installation process will automatically begin.
 
   .. note::
      The answers will be saved to a file ``/tmp/<findface-installer-*>.json``. You can edit this file and use it to install ``findface-video-worker`` on other hosts without having to answer the questions again. See :ref:`installation-file` for details.

   .. code::

      sudo ./<findface-security-and-server-xxx>.run -f /tmp/<findface-installer-*>.json

.. note::
   If you chose to install ``findface-ntls`` and/or ``findface-video-manager`` on different hosts than that with ``findface-sf-api``, specify their IP addresses in the ``findface-video-worker`` configuration file after the installation.

   .. code::
    
      sudo vi /etc/findface-video-worker-cpu.ini
      sudo vi /etc/findface-video-worker-gpu.ini

   In the ``ntls-addr`` parameter, specify the ``findface-ntls`` host IP address.

   .. code::

      ntls-addr=127.0.0.1:3133

   In the ``mgr-static`` parameter, specify the ``findface-video-manager`` host IP address, which provides ``findface-video-worker`` with settings and the video stream list.

   .. code::
 
      mgr-static=127.0.0.1:18811
