Nominatim is an open-source tool that helps in searching and reverse-geocoding geographical locations based on OpenStreetMap data. In this tutorial, we will discuss the steps to install Nominatim on Fedora CoreOS latest.

Prerequisites

• Machine or Virtual Machine with the latest version of Fedora CoreOS installed.
• Root access.
• At least 10GB of free disk space.

Steps to Install Nominatim

Step 1: Install Required Packages

Firstly, update the system and install the required packages using the following command:

sudo dnf update -y && sudo dnf install -y postgresql-server postgis proj-devel geos-devel osmium-tool bzip2 unzip planet.osm

Step 2: Set Up PostgreSQL Database

Next, create a new PostgreSQL database cluster and initialize it using the following command:

sudo postgresql-setup --initdb

After setting up the database, start the PostgreSQL service using the following command:

sudo systemctl start postgresql

Step 3: Install Nominatim

Download Nominatim by using the following command:

sudo git clone --recursive https://github.com/openstreetmap/Nominatim.git /opt/Nominatim

Navigate to the Nominatim directory:

cd /opt/Nominatim

Compile and install Nominatim:

sudo mk/build.sh
sudo make install

Step 4: Import OpenStreetMap Data

Download OpenStreetMap data of your preferred region or country using the following command:

sudo osm2pgsql -c -d nominatim -U postgres --slim --hstore --exclude-invalid-polygon -S /opt/Nominatim/src/pgsimple.style <region/country>-latest.osm.pbf

This command will import the OpenStreetMap data to the Nominatim database.

Step 5: Configure Nominatim

Create a custom configuration file for Nominatim using the following command:

sudo cp /opt/Nominatim/build/settings/local.php.sample /opt/Nominatim/build/settings/local.php

Edit the local.php file using the following command:

sudo nano /opt/Nominatim/build/settings/local.php

Update the following lines with your PostgreSQL and OpenStreetMap data details:

// Database connection settings
@define('CONST_Database_DSN', 'pgsql://username:password@localhost/nominatim');
@define('CONST_Database_ReadOnly_DSN', 'pgsql://username:password@localhost/nominatim');

...

// Email address for error reports
@define('CONST_Website_AdminEmail', '[email protected]');

Save and close the file.

Step 6: Start Nominatim Service

Start the Nominatim service using the following command:

sudo systemctl start nominatim

Step 7: Test Nominatim Installation

To test the Nominatim installation, run the following command:

sudo nominatim -v -s 'Country/City' 'Location'
