HOWTO run your own map servers.


Debian
======
Using Debian stable (12/bookworm).

Install dependenices:

.. code-block:: sh

  sudo apt install apache2 python3-certbot-apache \
  osm2pgsql postgresql-postgis postgresql-postgis-scripts \
  pkg-config libicu-dev virtualenv python3-pip \
  build-essential python3-dev


Firewall
========
Open ports 80 and 443 for web.

Apache
======
Install and set up Apache.

.. code-block:: sh

  certbot -d maps.libre.is -d map.libre.is
  # remove old apache configs:
  rm /etc/apache2/sites-enabled/000-default*

Add new apache configs to /etc/apache2/sites-available/maps-libre-is.conf:

.. code-block:: apache

  <VirtualHost maps.libre.is:80>
          ServerName maps.libre.is
          ServerAlias map.libre.is
          ServerAdmin webmaster@libre.is
          DocumentRoot /var/www/html/maps-libre-is
          ErrorLog ${APACHE_LOG_DIR}/error-libre-maps-is.log
          CustomLog ${APACHE_LOG_DIR}/access-libre-maps-is.log combined
          RewriteEngine on
          ReWriteCond %{HTTPS} off
          RewriteCond %{SERVER_NAME} =map.libre.is
          RewriteRule ^ https://maps.libre.is%{REQUEST_URI} [END,NE,R=permanent]
          ReWriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
          RewriteCond %{SERVER_NAME} =maps.libre.is
          RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
  </VirtualHost>
  
  <VirtualHost maps.libre.is:443>
          ServerName maps.libre.is
          ServerAlias map.libre.is
          ServerAdmin webmaster@libre.is
          DocumentRoot /var/www/html/maps-libre-is
          ErrorLog ${APACHE_LOG_DIR}/error-ssl-libre-maps-is.log
          CustomLog ${APACHE_LOG_DIR}/access-ssl-libre-maps-is.log combined
          RewriteEngine on
          RewriteCond %{SERVER_NAME} =map.libre.is
          RewriteRule ^ https://maps.libre.is%{REQUEST_URI} [END,NE,R=permanent]
          ReWriteCond %{HTTPS} off [OR]
          ReWriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
          ReWriteRule ^(.*)$ https://%1$1 [L,R=301]
          <Directory /var/www/html/maps-libre-is>
                  Options FollowSymlinks
                  AllowOverride All
                  Require all granted
          </Directory>
          Include /etc/letsencrypt/options-ssl-apache.conf
          SSLCertificateFile /etc/letsencrypt/live/maps.libre.is/fullchain.pem
          SSLCertificateKeyFile /etc/letsencrypt/live/maps.libre.is/privkey.pem
  </VirtualHost>
  # vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Enable new configuration:

.. code-block:: sh

  sudo mkdir -p /var/www/html/maps-libre-is
  echo maps.libre.is | sudo tee /var/www/html/maps-libre-is/index.html
  sudo ln -s /etc/apache2/sites-available/maps-libre-is.conf /etc/apache2/sites-enabled/maps-libre-is.conf
  sudo systemctl restart apache2  



Nominatim
=========
"Nominatim uses OpenStreetMap data to find locations on Earth by name and
address (geocoding).
It can also do the reverse, find an address for any location on the planet."

  `<https://nominatim.org/>`_

  `<https://github.com/osm-search/Nominatim>`_

  `<https://nominatim.org/release-docs/latest/admin/Installation/>`_

The full installation is quite demanding:

* 2GB RAM minimum.

* Full planet import requires 128GB of RAM or more.

* Full planet needs at least 1TB of fast disk.

* Full import of planet takes 2.5 days on NVMe, 4-5 days on SSD.

With the large disk, create a mount in /srv.

Set up Nominatim user and switch to it.

.. code-block:: sh

  sudo useradd -d /srv/nominatim -s /bin/bash -m nominatim
  sudo -u nominatim bash
  export USERNAME=nominatim
  export USERHOME=/srv/nominatim
  chmod a+x $USERHOME


Postgres
========
Postgres is needed by Nominatim.

.. code-block:: sh

  export USERNAME=nominatim
  export USERHOME=/srv/nominatim
  sudo systemctl restart postgresql
  sudo -u postgres createuser -s $USERNAME
  sudo -u postgres createuser www-data


Nominatim Install
=================
As user nominatim.

.. code-block::

  sudo -u nominatim bash
  export USERNAME=nominatim
  export USERHOME=/srv/nominatim
  virtualenv $USERHOME/nominatim-venv
  $USERHOME/nominatim-venv/bin/pip install nominatim-db
  . $USERHOME/nominatim-venv/bin/activate
