Note: these installation instructions are also available in executable form for use with vagrant under vagrant/Install-on-Ubuntu-16.sh.
Installing the Required Software
These instructions expect that you have a freshly installed Ubuntu 16.04.
Make sure all packages are are up-to-date by running:
sudo apt-get update -qq
Now you can install all packages needed for Nominatim:
sudo apt-get install -y build-essential cmake g++ libboost-dev libboost-system-dev \ libboost-filesystem-dev libexpat1-dev zlib1g-dev libxml2-dev\ libbz2-dev libpq-dev libgeos-dev libgeos++-dev libproj-dev \ postgresql-server-dev-9.5 postgresql-9.5-postgis-2.2 postgresql-contrib-9.5 \ apache2 php php-pgsql libapache2-mod-php php-pear php-db \ php-intl git
If you want to run the test suite, you need to install the following additional packages:
sudo apt-get install -y python3-dev python3-pip python3-psycopg2 python3-tidylib phpunit pip3 install --user behave nose # urllib3 sudo pear install PHP_CodeSniffer
The following steps are meant to configure a fresh Ubuntu installation for use with Nominatim. You may skip some of the steps if you have your OS already configured.
Creating Dedicated User Accounts
Nominatim will run as a global service on your machine. It is therefore best to install it under its own separate user account. In the following we assume this user is called nominatim and the installation will be in /srv/nominatim. To create the user and directory run:
sudo useradd -d /srv/nominatim -s /bin/bash -m nominatim
You may find a more suitable location if you wish.
To be able to copy and paste instructions from this manual, export user name and home directory now like this:
export USERNAME=nominatim export USERHOME=/srv/nominatim
Never, ever run the installation as a root user. You have been warned.
Make sure that system servers can read from the home directory:
chmod a+x $USERHOME
Setting up PostgreSQL
Tune the postgresql configuration, which is located in
/etc/postgresql/9.5/main/postgresql.conf. See section Postgres Tuning in
the installation page for the parameters to change.
Restart the postgresql service after updating this config file.
sudo systemctl restart postgresql
Finally, we need to add two postgres users: one for the user that does the import and another for the webserver which should access the database for reading only:
sudo -u postgres createuser -s $USERNAME sudo -u postgres createuser www-data
Setting up the Apache Webserver
You need to create an alias to the website directory in your apache configuration. Add a separate nominatim configuration to your webserver:
sudo tee /etc/apache2/conf-available/nominatim.conf << EOFAPACHECONF <Directory "$USERHOME/Nominatim/build/website"> Options FollowSymLinks MultiViews AddType text/html .php DirectoryIndex search.php Require all granted </Directory> Alias /nominatim $USERHOME/Nominatim/build/website EOFAPACHECONF
Then enable the configuration and restart apache
sudo a2enconf nominatim sudo systemctl restart apache2
Building and Configuration
Get the source code package of the realese, unpack it and change into the source directory
cd $USERHOME wget http://www.nominatim.org/release/Nominatim-3.0.0.tar.bz2 tar xf Nominatim-3.0.0.tar.bz2 cd Nominatim-3.0.0
The code must be built in a separate directory. Create this directory, then configure and build Nominatim in there:
mkdir build cd build cmake .. make
You need to create a minimal configuration file that tells nominatim where it is located on the webserver:
tee settings/local.php << EOF <?php @define('CONST_Website_BaseURL', '/nominatim/'); EOF
Nominatim is now ready to use. Continue with importing a database from OSM data.
