1 # Install Nominatim in a virtual machine for development and testing
3 This document describes how you can install Nominatim inside a Ubuntu 16
4 virtual machine on your desktop/laptop (host machine). The goal is to give
5 you a development environment to easily edit code and run the test suite
6 without affecting the rest of your system.
8 The installation can run largely unsupervised. You should expect 1h from
9 start to finish depending on how fast your computer and download speed
14 1. [Virtualbox](https://www.virtualbox.org/wiki/Downloads)
16 2. [Vagrant](https://www.vagrantup.com/downloads.html)
20 git clone --recursive https://github.com/openstreetmap/Nominatim.git
22 If you forgot `--recursive`, it you can later load the submodules using
31 1. Start the virtual machine
35 2. Log into the virtual machine
39 3. Import a small country (Monaco)
41 See the FAQ how to skip this step and point Nominatim to an existing database.
44 # inside the virtual machine:
46 wget --no-verbose --output-document=/tmp/dump.osm.pbf http://download.geofabrik.de/europe/monaco-latest.osm.pbf
47 cd /nominatim && nominatim import --osm-file /tmp/dump.osm.pbf
50 To repeat an import you'd need to delete the database first
52 dropdb --if-exists nominatim
58 Vagrant maps the virtual machine's port 8089 to your host machine. Thus you can
59 see Nominatim in action on [locahost:8089](http://localhost:8089/nominatim/).
61 You edit code on your host machine in any editor you like. There is no need to
62 restart any software: just refresh your browser window.
64 Note that the webserver uses files from the /build directory. If you change
65 files in Nominatim/website or Nominatim/utils for example you first need to
66 copy them into the /build directory by running the `cmake` step from the
69 PHP errors are written to `/var/log/apache2/error.log`.
71 With `echo` and `var_dump()` you write into the output (HTML/XML/JSON) when
72 you either add `&debug=1` to the URL (preferred) or set
73 `@define('CONST_Debug', true);` in `settings/local.php`.
75 In the Python BDD test you can use `logger.info()` for temporary debug
82 cd ~/Nominatim/tests/php
86 ## Running PHP code style tests
92 ## Running functional tests
94 Tests in `test/bdd/db` and `test/bdd/osm2pgsql` have to pass 100%. Other
95 tests might require full planet-wide data. Sadly even if you have your own
96 planet-wide data there will be enough differences to the openstreetmap.org
97 installation to cause false positives in the other tests (see FAQ).
99 To run the full test suite
101 cd ~/Nominatim/test/bdd
102 behave -DBUILDDIR=/home/vagrant/build/ db osm2pgsql
106 behave -DBUILDDIR=/home/vagrant/build/ api/lookup/simple.feature
108 Or a single test by line number
110 behave -DBUILDDIR=/home/vagrant/build/ api/lookup/simple.feature:34
112 To run specific groups of tests you can add tags just before the `Scenario line`, e.g.
115 Scenario: address lookup for non-existing or invalid node, way, relation
119 behave -DBUILDDIR=/home/vagrant/build/ --tags @bug-34
128 ##### Will it run on Windows?
130 Yes, Vagrant and Virtualbox can be installed on MS Windows just fine. You need a 64bit
134 ##### Why Monaco, can I use another country?
136 Of course! The Monaco import takes less than 30 minutes and works with 2GB RAM.
138 ##### Will the results be the same as those from nominatim.openstreetmap.org?
140 No. Long running Nominatim installations will differ once new import features (or
141 bug fixes) get added since those usually only get applied to new/changed data.
143 Also this document skips the optional Wikipedia data import which affects ranking
144 of search results. See [Nominatim installation](https://nominatim.org/release-docs/latest/admin/Installation) for details.
146 ##### Why Ubuntu? Can I test CentOS/Fedora/CoreOS/FreeBSD?
148 There is a Vagrant script for CentOS available, but the Nominatim directory
149 isn't symlinked/mounted to the host which makes development trickier. We used
150 it mainly for debugging installation with SELinux.
152 In general Nominatim will run in the other environments. The installation steps
153 are slightly different, e.g. the name of the package manager, Apache2 package
154 name, location of files. We chose Ubuntu because that is closest to the
155 nominatim.openstreetmap.org production environment.
157 You can configure/download other Vagrant boxes from [https://app.vagrantup.com/boxes/search](https://app.vagrantup.com/boxes/search).
159 ##### How can I connect to an existing database?
161 Let's say you have a Postgres database named `nominatim_it` on server `your-server.com` and port `5432`. The Postgres username is `postgres`. You can edit `settings/local.php` and point Nominatim to it.
163 pgsql:host=your-server.com;port=5432;user=postgres;dbname=nominatim_it
165 No data import or restarting necessary.
167 If the Postgres installation is behind a firewall, you can try
169 ssh -L 9999:localhost:5432 your-username@your-server.com
171 inside the virtual machine. It will map the port to `localhost:9999` and then
172 you edit `settings/local.php` with
174 @define('CONST_Database_DSN', 'pgsql:host=localhost;port=9999;user=postgres;dbname=nominatim_it');
176 To access postgres directly remember to specify the hostname, e.g. `psql --host localhost --port 9999 nominatim_it`
179 ##### My computer is slow and the import takes too long. Can I start the virtual machine "in the cloud"?
181 Yes. It's possible to start the virtual machine on [Amazon AWS (plugin)](https://github.com/mitchellh/vagrant-aws)
182 or [DigitalOcean (plugin)](https://github.com/smdahlen/vagrant-digitalocean).
