# Advanced installations
|
||
|
||
This page contains instructions for setting up multiple countries in
|
||
your Nominatim database. It is assumed that you have already successfully
|
||
installed the Nominatim software itself, if not return to the
|
||
[installation page](Installation.md).
|
||
|
||
## Importing multiple regions
|
||
|
||
To import multiple regions in your database, you need to configure and run `utils/import_multiple_regions.sh` file. This script will set up the update directory which has the following structure:
|
||
|
||
```bash
|
||
update
|
||
├── europe
|
||
│ ├── andorra
|
||
│ │ └── sequence.state
|
||
│ └── monaco
|
||
│ └── sequence.state
|
||
└── tmp
|
||
├── combined.osm.pbf
|
||
└── europe
|
||
├── andorra-latest.osm.pbf
|
||
└── monaco-latest.osm.pbf
|
||
|
||
|
||
```
|
||
|
||
The `sequence.state` files will contain the sequence ID, which will be used by pyosmium to get updates. The tmp folder is used for import dump.
|
||
|
||
### Configuring multiple regions
|
||
|
||
The file `import_multiple_regions.sh` needs to be edited as per your requirement:
|
||
|
||
1. List of countries. eg:
|
||
|
||
COUNTRIES="europe/monaco europe/andorra"
|
||
|
||
2. Path to Build directory. eg:
|
||
|
||
NOMINATIMBUILD="/srv/nominatim/build"
|
||
|
||
3. Path to Update directory. eg:
|
||
|
||
UPDATEDIR="/srv/nominatim/update"
|
||
|
||
4. Replication URL. eg:
|
||
|
||
BASEURL="https://download.geofabrik.de"
|
||
DOWNCOUNTRYPOSTFIX="-latest.osm.pbf"
|
||
|
||
!!! tip
|
||
If your database already exists and you want to add more countries, replace the setting up part
|
||
`${SETUPFILE} --osm-file ${UPDATEDIR}/tmp/combined.osm.pbf --all 2>&1`
|
||
with `${UPDATEFILE} --import-file ${UPDATEDIR}/tmp/combined.osm.pbf 2>&1`.
|
||
|
||
### Setting up multiple regions
|
||
|
||
Run the following command from your Nominatim directory after configuring the file.
|
||
|
||
bash ./utils/import_multiple_regions.sh
|
||
|
||
!!! danger "Important"
|
||
This file uses osmium-tool. It must be installed before executing the import script.
|
||
Installation instructions can be found [here](https://osmcode.org/osmium-tool/manual.html#installation).
|
||
|
||
## Updating multiple regions
|
||
|
||
To import multiple regions in your database, you need to configure and run ```utils/update_database.sh```.
|
||
This uses the update directory set up while setting up the DB.
|
||
|
||
### Configuring multiple regions
|
||
|
||
The file `update_database.sh` needs to be edited as per your requirement:
|
||
|
||
1. List of countries. eg:
|
||
|
||
COUNTRIES="europe/monaco europe/andorra"
|
||
|
||
2. Path to Build directory. eg:
|
||
|
||
NOMINATIMBUILD="/srv/nominatim/build"
|
||
|
||
3. Path to Update directory. eg:
|
||
|
||
UPDATEDIR="/srv/nominatim/update"
|
||
|
||
4. Replication URL. eg:
|
||
|
||
BASEURL="https://download.geofabrik.de"
|
||
DOWNCOUNTRYPOSTFIX="-updates"
|
||
|
||
5. Followup can be set according to your installation. eg: For Photon,
|
||
|
||
FOLLOWUP="curl http://localhost:2322/nominatim-update"
|
||
|
||
will handle the indexing.
|
||
|
||
### Updating the database
|
||
|
||
Run the following command from your Nominatim directory after configuring the file.
|
||
|
||
bash ./utils/update_database.sh
|
||
|
||
This will get diffs from the replication server, import diffs and index the database. The default replication server in the script([Geofabrik](https://download.geofabrik.de)) provides daily updates.
