wget http://download.geofabrik.de/asia/maldives-latest.osm.pbf
./utils/setup.php --osm-file maldives-latest.osm.pbf --all --osm2pgsql-cache 18000 2>&1 | tee setup.log
exit

Step 7: Configure Nginx

Now you need to configure Nginx for Nominatim. Type the following command in your terminal:

sudo apt install nginx -y
sudo nano /etc/nginx/sites-available/nominatim.conf

Add the following code to the conf file:

server {
        listen 8080;
        server_name localhost;

        location / {
                proxy_pass http://localhost:8085;
                proxy_set_header Host $http_host;

sudo ln -s /etc/nginx/sites-available/nominatim.conf /etc/nginx/sites-enabled/

Restart nginx service:

sudo systemctl restart nginx

Step 8: Start Nominatim

Finally, you can start Nominatim. Type the following command in your terminal:

sudo su - nominatim -s /bin/bash
./Nominatim/nominatim -p 8085 --osm2pgsql-cache 18000
