1 # Install Nominatim in a virtual machine for development and testing
3 This document describes how you can install Nominatim inside a Ubuntu 24
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 https://github.com/openstreetmap/Nominatim.git
24 1. Start the virtual machine
26 vagrant up ubuntu24-nginx
28 2. Log into the virtual machine
30 vagrant ssh ubuntu24-nginx
32 3. Import a small country (Monaco)
34 See the FAQ how to skip this step and point Nominatim to an existing database.
37 # inside the virtual machine:
39 wget --no-verbose --output-document=monaco.osm.pbf http://download.geofabrik.de/europe/monaco-latest.osm.pbf
40 nominatim import --osm-file monaco.osm.pbf 2>&1 | tee monaco.$$.log
43 To repeat an import you'd need to delete the database first
45 dropdb --if-exists nominatim
51 Vagrant maps the virtual machine's port 8089 to your host machine. Thus you can
52 see Nominatim in action on [localhost:8089](http://localhost:8089/nominatim/).
54 You edit code on your host machine in any editor you like. There is no need to
55 restart any software: just refresh your browser window.
57 Use the functions of the `log()` object to create temporary debug output.
58 Add `&debug=1` to the URL to see the output.
60 In the Python BDD test you can use `logger.info()` for temporary debug

69 ##### Will it run on Windows?
71 Yes, Vagrant and Virtualbox can be installed on MS Windows just fine. You need
72 a 64bit version of Windows.
74 ##### Will it run on Apple Silicon?
76 You might need to replace Virtualbox with [Parallels](https://www.parallels.com/products/desktop/).
77 There is no free/open source version of Parallels.
79 ##### Why Monaco, can I use another country?
81 Of course! The Monaco import takes less than 10 minutes and works with 2GB RAM.
83 ##### Will the results be the same as those from nominatim.openstreetmap.org?
85 No. Long-running Nominatim installations will differ once new import features (or
86 bug fixes) get added since those usually only get applied to new/changed data.
88 Also this document skips the optional Wikipedia data import which affects ranking
89 of search results. See [Nominatim installation](https://nominatim.org/release-docs/latest/admin/Installation)
92 ##### Why Ubuntu? Can I test CentOS/Fedora/CoreOS/FreeBSD?
94 There used to be a Vagrant script for CentOS available, but the Nominatim directory
95 isn't symlinked/mounted to the host which makes development trickier. We used
96 it mainly for debugging installation with SELinux.
98 In general Nominatim will run in the other environments. The installation steps
99 are slightly different, e.g. the name of the package manager, Apache2 package
100 name, location of files. We chose Ubuntu because that is closest to the
101 nominatim.openstreetmap.org production environment.
103 You can configure/download other Vagrant boxes from
104 [https://app.vagrantup.com/boxes/search](https://app.vagrantup.com/boxes/search).
106 ##### How can I connect to an existing database?
108 Let's say you have a Postgres database named `nominatim_it` on server `your-server.com`
109 and port `5432`. The Postgres username is `postgres`. You can edit the `.env` in your
110 project directory and point Nominatim to it.
112 NOMINATIM_DATABASE_DSN="pgsql:host=your-server.com;port=5432;user=postgres;dbname=nominatim_it
114 No data import or restarting necessary.
116 If the Postgres installation is behind a firewall, you can try
118 ssh -L 9999:localhost:5432 your-username@your-server.com
120 inside the virtual machine. It will map the port to `localhost:9999` and then
121 you edit `.env` file with
123 NOMINATIM_DATABASE_DSN="pgsql:host=localhost;port=9999;user=postgres;dbname=nominatim_it"
125 To access postgres directly remember to specify the hostname,
126 e.g. `psql --host localhost --port 9999 nominatim_it`
129 ##### My computer is slow and the import takes too long. Can I start the virtual machine "in the cloud"?
131 Yes. It's possible to start the virtual machine on [Amazon AWS (plugin)](https://github.com/mitchellh/vagrant-aws)
132 or [DigitalOcean (plugin)](https://github.com/smdahlen/vagrant-digitalocean).
