Install NodeJS & CartoCSS (Mapnik Stylesheet Compiler)

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo npm install -g carto

Install osm2pgsql

git clone git://github.com/openstreetmap/osm2pgsql.git
cd osm2pgsql
mkdir build && cd build
cmake ..
make
sudo make install

Install mod_tile

sudo mkdir /var/lib/mod_tile
sudo chown $USER /var/lib/mod_tile

git clone git://github.com/SomeoneElseOSM/mod_tile.git
cd mod_tile
./autogen.sh
./configure
make
sudo make install
sudo make install-mod_tile
sudo ldconfig

Create mod_tile module for Apache

Create /etc/apache2/mods-available/tile.load file :

LoadModule tile_module /usr/lib/apache2/modules/mod_tile.so

Create /etc/apache2/mods-available/tile.conf file :

<IfModule tile_module>
   LoadTileConfigFile /usr/local/etc/renderd.conf
   ModTileRenderdSocketName /var/run/renderd/renderd.sock
   # Timeout before giving up for a tile to be rendered
   ModTileRequestTimeout 0
   # Timeout before giving up for a tile to be rendered that is otherwise missing
   ModTileMissingRequestTimeout 30
</IfModule>

Update mod_tile configuration file :

Update needed parameters :

• num_threads : should match the number of (v)CPU
• plugins_dir : use mapnik-config --input-plugins to get the directory where Mapnik plugins are stored

Add following to file /usr/local/etc/renderd.conf :

[osmbe]
URI=/osmbe/
TILEDIR=/var/lib/mod_tile
XML=/home/ubuntu/src/openstreetmap-carto-be/mapnik.xml
HOST=localhost
TILESIZE=256
MAXZOOM=18
CORS=*

[osmbe-fr]
URI=/osmbe-fr/
TILEDIR=/var/lib/mod_tile
XML=/home/ubuntu/src/openstreetmap-carto-be/mapnik-fr.xml
HOST=localhost
TILESIZE=256
MAXZOOM=18
CORS=*

[osmbe-nl]
URI=/osmbe-nl/
TILEDIR=/var/lib/mod_tile
XML=/home/ubuntu/src/openstreetmap-carto-be/mapnik-nl.xml
HOST=localhost
TILESIZE=256
MAXZOOM=18
CORS=*

Enable mod_tile :

sudo a2enmod tile
sudo service apache2 restart

Enable connection to database

Make sure the IP address of the database server is correct in project.mml !

You will need to use ~/.pgpass file to define the password to connect to PostgreSQL : https://www.postgresql.org/docs/current/libpq-pgpass.html.
