How to Install Nominatim on NetBSD

Nominatim is a tool that can be used for geocoding addresses and reverse geocoding coordinates. This tutorial will guide you through the installation process of Nominatim on NetBSD.

Prerequisites

Before we proceed with the installation, make sure that the following prerequisites are met:

NetBSD is installed on your machine
You have a working internet connection
You have administrative privileges on your system

Step 1 - Install Required Dependencies

We need to install the required dependencies for Nominatim to work. Run the following command to install them:

sudo pkgin update
sudo pkgin install build-essential git libxml2 libxml2-dev libgeos libgeos-dev libpqxx libpqxx-dev proj proj-dev proj-bin proj-data curl php php7-pgsql php-fpm pgsql-server

Step 2 - Download Nominatim from Git

Next, we need to download Nominatim from Git. Run the following commands to clone the repository:

cd /usr/local
sudo git clone --recursive https://github.com/openstreetmap/Nominatim.git

Step 3 - Configure and Build Nominatim

In this step, we need to configure and build the Nominatim project. Run the following commands:

cd Nominatim
sudo ./autogen.sh
sudo ./configure --with-postgresql-libraries=/usr/pkg/lib --with-postgresql-includes=/usr/pkg/include/pgsql/server/
sudo make

This process might take some time to complete. Once done, you can verify the build by running the following command:

sudo make install

Step 4 - Configure PostgreSQL

Now, we need to configure PostgreSQL to work with Nominatim. Run the following commands:

sudo su - postgres
createdb nominatim
psql -c "CREATE USER nominatim WITH PASSWORD 'password';"
psql -c "ALTER USER nominatim WITH SUPERUSER;"

Step 5 - Setup Nominatim

In this step, we need to setup Nominatim by creating a configuration file. Navigate to the nominatim directory and run the following command:

cd /usr/local/Nominatim
sudo cp ./local.php.dist ./local.php

Edit the local.php file with your appropriate configurations. Replace the [email protected] with your email address. Also, replace the values as shown below:

@define('CONST_Database_DSN', 'pgsql://nominatim:password@localhost/nominatim');
@define('CONST_Osm2pgsql_Binary', '/usr/local/bin/osm2pgsql');
@define('CONST_Pyosmium_Binary', '/usr/local/bin/pyosmium-get-changes');
@define('CONST_Mapnik2_Binary', '/usr/local/bin/mapnik-render');
@define('CONST_Map_Config_File', '/usr/local/share/maps/style/osm-carto/mapnik.xml');
@define ('CONST_Website_BaseURL', 'http://127.0.0.1/nominatim/');
@define('CONST_MultipleSearchServers', '0');
@define('CONST_Database_ReadOnly', '0');
@define('CONST_Show_Quadtree', 0);

Save and close the file.

Step 6 - Import Data

Finally, we can now import the data. To do this, first download the OSM data for your desired region from Geofabrik and save the .osm.pbf file in /usr/local/share/nominatim/data.

Run the following command to import data:

sudo ./utils/setup.php --osm-file /usr/local/share/nominatim/data/<your_file>.osm.pbf --all --osm2pgsql-cache 20000

This process might take some time to complete. Once done, you can start the Nominatim service:

sudo cp /usr/local/Nominatim/utils/systemd/nominatim.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl start nominatim

Conclusion

You have successfully installed and configured Nominatim on NetBSD. You can now use it to geocode addresses and reverse geocode coordinates.
