Deploy Step-by-Step from Repository

This section will guide you through the FindFace Multi step-by-step deployment process. Follow the instructions below minding the sequence.

In this section:

Install APT Repository

First of all, install the FindFace apt repository as follows:

  1. Download the installer file

  2. Put the .run file into some directory on the designated host (for example, /home/username).

  3. From this directory, make the .run file executable.

    chmod +x
  4. Execute the .run file.

    sudo ./

    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 and answers are the following:

    1. Product to install: FindFace Multi.

    2. Installation type: repo: Don't install anything, just set up the APT repository.

    3. Neural network models to install if necessary. To select a model(s), deselect all those on the list by entering -* in the command line, then select the required models by entering their sequence numbers (keyword): for example, 1 3 4. Enter done to save your selection and proceed to another step.


      You must install at least one face biometry model.

    After that, the FindFace apt repository will be automatically installed.


FindFace Multi requires such third-party software as PostgreSQL, Pgbouncer, NATS, etcd, and memcached. Do the following:

  1. Install the prerequisite packages as such:

    sudo apt update
    sudo apt install -y postgresql-10 nats-server etcd memcached pgbouncer
  2. Open the /etc/memcached.conf configuration file. Set the maximum memory in megabytes to use for memcached items: -m 1024. Set the maximum item size: -I 16m. If one or both of these parameters are absent, add them to the file.

    sudo vi /etc/memcached.conf
    -m 1024
    -I 16m
  3. Give a strong password to the ntech user (9T3g1nXy9yx3y8MIGm9fbef3dia8UTc3 in the example below). Output the credentials to the pgbouncer user list.

    echo '"ntech" "9T3g1nXy9yx3y8MIGm9fbef3dia8UTc3"' | sudo tee -a /etc/pgbouncer/userlist.txt
  4. Configure pgbouncer. In /etc/pgbouncer/pgbouncer.ini, add the ffsecurity database to the databases section. Configure named parameters, as shown in the example below. Parameters other than those must be commented out.

    sudo vi /etc/pgbouncer/pgbouncer.ini
    ffsecurity = dbname=ffsecurity host=localhost port=5432 user=ntech
    pidfile = /var/run/postgresql/
    listen_addr =
    listen_port = 5439
    unix_socket_dir = /var/run/postgresql
    auth_type = plain
    auth_file = /etc/pgbouncer/userlist.txt
    pool_mode = transaction
    server_reset_query = DISCARD ALL
    max_client_conn = 16384
    default_pool_size = 20
    syslog = 1
  5. Enable the prerequisite services autostart and launch the services:

    sudo systemctl enable postgresql@10-main.service nats-server etcd.service memcached.service pgbouncer.service
    sudo systemctl restart postgresql@10-main.service nats-server etcd.service memcached.service pgbouncer.service

Provide Licensing


See Licensing Info to learn about the NtechLab licensing policy.

To provide the FindFace Multi licensing, deploy findface-ntls, license server in the FindFace core.


There must be only one findface-ntls instance in each FindFace Multi installation.

sudo apt update
sudo apt install -y findface-ntls
sudo systemctl enable findface-ntls.service && sudo systemctl start findface-ntls.service

Deploy Main Database

In FindFace Multi, the main system database is based on PostgreSQL. To deploy the main database, do the following:

  1. Open the pgbouncer list of users /etc/pgbouncer/userlist.txt. Copy the ntech user’s password (9T3g1nXy9yx3y8MIGm9fbef3dia8UTc3 in the example below).

    sudo cat /etc/pgbouncer/userlist.txt
    "ntech" "9T3g1nXy9yx3y8MIGm9fbef3dia8UTc3"
  2. Using the PostgreSQL console, create a new user ntech with the copied password, and databases ffsecurity and ffcounter in PostgreSQL.

    sudo -u postgres psql
    postgres=# CREATE ROLE ntech WITH LOGIN PASSWORD '9T3g1nXy9yx3y8MIGm9fbef3dia8UTc3';
    postgres=# CREATE DATABASE ffsecurity WITH OWNER ntech ENCODING 'UTF-8' LC_COLLATE='en_US.UTF-8' LC_CTYPE='en_US.UTF-8' TEMPLATE template0;
    postgres=# CREATE DATABASE ffcounter WITH OWNER ntech ENCODING 'UTF-8' LC_COLLATE='C.UTF-8' LC_CTYPE='C.UTF-8' TEMPLATE template0;


    To quit from the PostgreSQL console, type \q and press Enter.

  3. Allow authentication by UID of a socket client in PostgreSQL. Restart PostgreSQL.

    echo 'local all ntech peer' | sudo tee -a /etc/postgresql/10/main/pg_hba.conf
    sudo systemctl restart postgresql@10-main.service

Deploy FindFace Core

To deploy the FindFace core, do the following:


You can find the description of the FindFace core components and their configuration parameters in Architecture and Components in Depth.

  1. For FindFace Multi on GPU, install NVIDIA drivers.


    Be sure the restart the server after the NVIDIA drivers installation is complete. Otherwise, the subsequent installation of the GPU-based components experiences a failure.

  2. Install the FindFace core components:

    sudo apt update
    sudo apt install -y findface-tarantool-server findface-extraction-api findface-sf-api findface-upload findface-video-manager findface-video-worker-cpu findface-liveness-api


    To install the GPU-accelerated findface-extraction-api component, use findface-extraction-api-gpu instead of findface-extraction-api in the command.


    To install the GPU-accelerated findface-video-worker component, use findface-video-worker-gpu instead of findface-video-worker-cpu in the command. If you have several video cards on your server, see Multiple Video Cards Usage.


    Be sure to manually install neural network models on the host(s) with findface-extraction-api.

  3. In the /etc/findface-sf-api.ini configuration file, enable the allow-return-facen parameter.

    sudo vi /etc/findface-sf-api.ini
      allow-return-facen: true
  4. Open the /etc/findface-video-worker-cpu.ini (/etc/findface-video-worker-gpu.ini) configuration file. Specify the following parameters:

    • 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.

    • In the capacity parameter, specify the maximum number of video streams to be processed by findface-video-worker.

    • In the streamer section, specify the IP address and port to access the Video Wall. The streamer port must be set to 18999. Set tracks = true to improve how the object bboxes are displayed on the Video Wall.

    sudo vi /etc/findface-video-worker-cpu.ini
    sudo vi /etc/findface-video-worker-gpu.ini
    ## streamer/shots webserver port, 0=disabled
    ## type:number env:CFG_STREAMER_PORT longopt:--streamer-port
    port = 18999
    ## streamer url - how to access this worker on streamer_port
    ## type:string env:CFG_STREAMER_URL longopt:--streamer-url
    url =
    ## use tracks instead detects for streamer
    ## type:bool env:CFG_STREAMER_TRACKS longopt:--streamer-tracks
    tracks = true
  5. Enable the FindFace core services autostart and launch the services.

    sudo systemctl enable findface-extraction-api findface-sf-api findface-video-manager findface-video-worker-cpu findface-liveness-api
    sudo systemctl start findface-extraction-api findface-sf-api findface-video-manager findface-video-worker-cpu findface-liveness-api

Deploy FindFace Multi Application Module and Feature Vector Database

To deploy the FindFace Multi application module, do the following:

  1. Install the findface-security, findface-security-ui, and findface-counter components. Enable the findface-counter autostart and launch the service.

    sudo apt update
    sudo apt install -y findface-security findface-security-ui findface-counter
    sudo systemctl enable findface-counter && sudo systemctl start findface-counter
  2. Migrate the database architecture from FindFace Multi to PostgreSQL, create user groups with predefined rights and the first user with administrator rights (a.k.a. Super Administrator).


    Super Administrator cannot be deprived of its rights, whatever the role.

    sudo findface-security migrate
    sudo findface-security create_groups
    sudo findface-security create_default_user
  3. Create a structure of the Tarantool-based feature vector database by executing the command below.

    sudo findface-security make_tnt_schema | sudo tee /etc/findface-security/tnt_schema.lua
  4. Open the /etc/tarantool/instances.available/FindFace.lua configuration file. Check whether it contains the dofile command, meta_indexes and meta_scheme definitions, as in the example below.

    sudo vi /etc/tarantool/instances.available/FindFace.lua
    -- host:port to bind, HTTP API
    FindFace = require("FindFace")
    FindFace.start("", 8101, {
        meta_scheme = meta_scheme


    The IP address and port number specified in the shards section of the /etc/findface-sf-api.ini configuration file must be identical to those in the FindFace.start section.

    sudo vi /etc/tarantool/instances.available/FindFace.lua
    FindFace.start("", 8101...)
    sudo vi /etc/findface-sf-api.ini
      - master:


    If you change the /etc/findface-sf-api.ini configuration file, be sure to restart the findface-sf-api service:

    sudo systemctl restart findface-sf-api.service
  5. Enable the findface-tarantool-server service autostart and launch the service.

    sudo systemctl enable tarantool@FindFace.service && sudo systemctl start tarantool@FindFace.service
  6. Open the /etc/findface-security/ configuration file. Specify the following parameters:


    You can find the /etc/findface-security/ default version here.

    • SERVICE_EXTERNAL_ADDRESS: FindFace Multi IP address or URL prioritized for the Genetec integration and webhooks. If this parameter is not specified, the system will be using EXTERNAL_ADDRESS for these purposes.


      To use Genetec and webhooks, be sure to specify at least one of these parameters: SERVICE_EXTERNAL_ADDRESS/EXTERNAL_ADDRESS.

    • EXTERNAL_ADDRESS: (Optional) IP address or URL used to access the FindFace Multi web interface. If this parameter is not manually set, the system auto-detects it as the external IP address of the host.


      To access FindFace Multi, you can use both the auto-detected and manually set IP addresses.

    • VIDEO_DETECTOR_TOKEN: to authorize the video object detection module, come up with a token and specify it here.

    • VIDEO_MANAGER_ADDRESS: IP address of the findface-video-manager host.

    • NTLS_HTTP_URL: IP address of the findface-ntls host.

    • ROUTER_URL: IP address of the findface-security host that will receive detected objects from the findface-video-worker instance(s). Specify either external or internal IP address, subject to the network through which findface-video-worker interacts with findface-security. Change the default port, subject to the redirect settings from HTTP to HTTPS, or omit it leaving only the IP address.

    • SF_API_ADDRESS: IP address of the findface-sf-api host.

    • DATABASES (section): fill it in as such: 'PORT': 5439, 'USER': 'ntech', 'PASSWORD': '<password from /etc/pgbouncer/userlist.txt>' (see Prerequisites).


    If necessary, ensure data security by enabling SSL.


    If necessary, set ’IGNORE_UNMATCHED’: True to disable logging events for the objects that have no match with the dossiers (negative verification result). Enable this option if the system has to process a large number of objects.

  7. Generate a signature key for the session encryption (used by Django) by executing the command below. Specify this key as SECRET_KEY.

    pwgen -sncy 50 1|tr "'" "."
  8. Start the services.

    sudo systemctl enable findface-security
    sudo systemctl start findface-security
  9. Disable the default nginx server and add the findface-security server to the list of enabled servers. Restart nginx.

    sudo rm /etc/nginx/sites-enabled/default
    sudo ln -s /etc/nginx/sites-available/ffsecurity-nginx.conf /etc/nginx/sites-enabled/
    sudo nginx -s reload
  10. Provide licensing:


    To log in for the first time, use the default Super Administrator account admin:admin.


To create more users or change the Super Administrator password, refer to User Management.


To preserve the FindFace Multi compatibility with the installation environment, we highly recommend you to disable the Ubuntu automatic update. In this case, you will be able to update your OS manually, fully controlling which packages to update.

To disable the Ubuntu automatic update, execute the following commands:

sudo apt-get remove unattended-upgrades
sudo systemctl stop apt-daily.timer
sudo systemctl disable apt-daily.timer
sudo systemctl disable apt-daily.service
sudo systemctl daemon-reload


The FindFace Multi services log a large amount of data, which can eventually lead to disc overload. To prevent this from happening, we advise you to disable rsyslog due to its suboptimal log rotation scheme and use the appropriately configured systemd-journal service instead. See Service Logs for the step-by-step instructions.
