The following instructions explain how to create a Nominatim database
from an OSM planet file. It is assumed that you have already successfully
-installed the Nominatim software itself. If this is not the case, return to the
+installed the Nominatim software itself and the `nominatim` tool can be found
+in your `PATH`. If this is not the case, return to the
[installation page](Installation.md).
## Creating the project directory
Before you start the import, you should create a project directory for your
new database installation. This directory receives all data that is related
to a single Nominatim setup: configuration, extra data, etc. Create a project
-directory apart from the Nominatim software:
+directory apart from the Nominatim software and change into the directory:
```
mkdir ~/nominatim-planet
+cd ~/nominatim-planet
```
In the following, we refer to the project directory as `$PROJECT_DIR`. To be
The Nominatim tool assumes per default that the current working directory is
the project directory but you may explicitly state a different directory using
-the `--project-dir` parameter. The following instructions assume that you have
-added the Nominatim build directory to your PATH and run all directories from
-the project directory. If you haven't done yet, add the build directory to your
-path and change to the new project directory:
-
-```
-export PATH=~/Nominatim/build:$PATH
-cd $PROJECT_DIR
-```
-
-Of course, you have to replace the path above with the location of your build
-directory.
+the `--project-dir` parameter. The following instructions assume that you run
+all commands from the project directory.

### Configuration setup in `.env`
-The Nominatim server can be customized via a `.env` in the project directory.
-This is a file in [dotenv](https://github.com/theskumar/python-dotenv) format
-which looks the same as variable settings in a standard shell environment.
+The Nominatim server can be customized via an `.env` configuration file in the
+project directory. This is a file in [dotenv](https://github.com/theskumar/python-dotenv)
+format which looks the same as variable settings in a standard shell environment.
You can also set the same configuration via environment variables. All
settings have a `NOMINATIM_` prefix to avoid conflicts with other environment
variables.
There are lots of configuration settings you can tweak. Have a look
-at `settings/env.default` for a full list. Most should have a sensible default.

#### Flatnode files
`nominatim refresh --wiki-data --importance`. Updating importances for
a planet can take a couple of hours.
-### Great Britain, USA postcodes
+### External postcodes
-Nominatim can use postcodes from an external source to improve searches that
-involve a GB or US postcode. This data can be optionally downloaded into the
-project directory:
+Nominatim can use postcodes from an external source to improve searching with
+postcodes. We provide precomputed postcodes sets for the US (using TIGER data)
+and the UK (using the [CodePoint OpenData set](https://osdatahub.os.uk/downloads/open/CodePointOpen).
+This data can be optionally downloaded into the project directory:
cd $PROJECT_DIR
- wget https://www.nominatim.org/data/gb_postcode_data.sql.gz
- wget https://www.nominatim.org/data/us_postcode_data.sql.gz
+ wget https://www.nominatim.org/data/gb_postcodes.csv.gz
+ wget https://www.nominatim.org/data/us_postcodes.csv.gz
+
+You can also add your own custom postcode sources, see
+[Customization of postcodes](Customization.md#external-postcode-data).
## Choosing the data to import
[Geofabrik](https://download.geofabrik.de).
Download the data to import. Then issue the following command
-from the **build directory** to start the import:
+from the **project directory** to start the import:
```sh
nominatim import --osm-file <data file> 2>&1 | tee setup.log
```
+The **project directory** is the one that you have set up at the beginning.
+See [creating the project directory](Import#creating-the-project-directory).

### Notes on full planet imports
Even on a perfectly configured machine
above. If the system starts swapping or you are getting out-of-memory errors,
reduce the cache size or even consider using a flatnode file.
-### Verify the import
+
+### Testing the installation
Run this script to verify all required tables and indices got created successfully.
```sh
-nominatim check-database
+nominatim admin --check-database
```
-### Testing the installation
-
Now you can try out your installation by running:
```sh
-make serve
+nominatim serve
```
This runs a small test server normally used for development. You can use it
`http://localhost:8088/status.php` and you should see the message `OK`.
You can also run a search query, e.g. `http://localhost:8088/search.php?q=Berlin`.
+Note that search query is not supported for reverse-only imports. You can run a
+reverse query, e.g. `http://localhost:8088/reverse.php?lat=27.1750090510034&lon=78.04209025`.
+
To run Nominatim via webservers like Apache or nginx, please read the
[Deployment chapter](Deployment.md).
If you want to be able to search for places by their type through
[special key phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases)
-you also need to enable these key phrases like this:
+you also need to import these key phrases like this:
- nominatim special-phrases --from-wiki > specialphrases.sql
- psql -d nominatim -f specialphrases.sql
+```sh
+nominatim special-phrases --import-from-wiki
+```
Note that this command downloads the phrases from the wiki link above. You
need internet access for the step.

-## Installing Tiger housenumber data for the US
-
-Nominatim is able to use the official [TIGER](https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html)
-address set to complement the OSM house number data in the US. You can add
-TIGER data to your own Nominatim instance by following these steps. The
-entire US adds about 10GB to your database.
-
- 1. Get preprocessed TIGER 2019 data and unpack it into your project
- directory:
-
- cd $PROJECT_DIR
- wget https://nominatim.org/data/tiger2019-nominatim-preprocessed.tar.gz
- tar xf tiger2019-nominatim-preprocessed.tar.gz
-
- 2. Import the data into your Nominatim database:
-
- nominatim add-data --tiger-data tiger
-
- 3. Enable use of the Tiger data in your `.env` by adding:
-
- echo NOMINATIM_USE_US_TIGER_DATA=yes >> .env
-
- 4. Apply the new settings:
-
- nominatim refresh --functions
-
-
-See the [developer's guide](../develop/data-sources.md#us-census-tiger) for more
-information on how the data got preprocessed.
-
+You can also import special phrases from a csv file, for more
+information please read the [Customization chapter](Customization.md).
