How to install Exadel CompreFace on NetBSD

Exadel CompreFace is a facial recognition technology used for security and identification purposes. In this tutorial, we will be going through the steps to install CompreFace on NetBSD, a free and open-source Unix-like operating system.

Prerequisites

Before we begin with the installation process, make sure you have the following prerequisites:

  • NetBSD operating system installed on your system
  • Root access to your NetBSD machine
  • Internet connection to download CompreFace

Step 1: Download CompreFace

Go to the Exadel CompreFace website and click on the "Download" button. Choose the appropriate version for NetBSD architecture and download the package.

Step 2: Install Dependencies

Exadel CompreFace requires Java SDK and PostgreSQL database to be installed on your machine. Since NetBSD uses the pkgsrc package manager, you can install these dependencies using the following commands:

$ pkgin update
$ pkgin install openjdk11 postgresql96-server

Step 3: Set up PostgreSQL

Start the PostgreSQL server using the following command:

$ /usr/pkg/bin/pg_ctl -D /var/postgresql/data96 start

Create a new user and database for CompreFace using the following commands:

$ su - postgres
$ createuser compreface
$ createdb -O compreface compreface

Step 4: Install CompreFace

Extract the downloaded CompreFace package using the following command:

$ tar xvf compreface-<version>-netbsd.tgz

Copy the extracted files to the desired directory, such as /opt/compreface using:

$ cp -R compreface-<version> /opt/compreface

Step 5: Configure CompreFace

Navigate to the conf directory within CompreFace, and edit the application.yml file to configure CompreFace:

$ cd /opt/compreface/conf
$ vi application.yml

Change the PostgreSQL configuration to match the following, replacing <PASSWORD> with the password for your compreface user:

spring:
  datasource:
    url: jdbc:postgresql://localhost:5432/compreface
    username: compreface
    password: <PASSWORD>

Save and exit the file.

Step 6: Start CompreFace

You can now start CompreFace using the following command:

$ /opt/compreface/bin/start.sh

CompreFace can be accessed at http://localhost:8000 in your web browser.

Conclusion

Congratulations! You have successfully installed Exadel CompreFace on NetBSD. You can now use facial recognition technology for your security and identification needs.
