Running Your Own Instance
Can I import only a few countries and also keep them up to date?
You should use the extracts and updates from https://download.geofabrik.de.
For the initial import, download the countries you need and merge them.
See OSM Help
for examples how to do that. Use the resulting single osm file when
For updates you need to download the change files for each country once per day and apply them separately using
./utils/update.php --import-diff <filename> --index
See this issue for a script that runs the updates using osmosis.

I accidentally killed the import process after it has been running for many hours. Can it be resumed?
It is possible if the import already got to the indexing stage. Check the last line of output that was logged before the process was killed. If it looks like this:
Done 844 in 13 @ 64.923080 per second - Rank 26 ETA (seconds): 7.886255
then you can resume with the following command:
./utils/setup.php --index --create-search-indices --create-country-names
If the reported rank is 26 or higher, you can also safely add
When running the setup.php script I get a warning:
`PHP Warning: file_get_contents(): open_basedir restriction in effect.`
You need to adjust the open_basedir setting in your PHP configuration (php.ini file). By default this setting may look like this:
open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/
Either add reported directories to the list or disable this setting temporarily by dding ";" at the beginning of the line. Don't forget to enable this setting again once you are done with the PHP command line operations.
The Apache log contains lots of PHP warnings like this:
`PHP Warning: date_default_timezone_set() function.`
You should set the default time zone as instructed in the warning in
php.ini file. Find the entry about timezone and set it to
something like this:
; Defines the default timezone used by the date functions ; http://php.net/date.timezone date.timezone = 'America/Denver'
echo "date.timezone = 'America/Denver'" > /etc/php.d/timezone.ini
When running the import I get a version mismatch:
`COPY_END for place failed: ERROR: incompatible library "/opt/Nominatim/module/nominatim.so": version mismatch`
pg_config seems to use bad includes sometimes when multiple versions
of PostgreSQL are available in the system. Make sure you remove the
server development libraries (
postgresql-server-dev-9.1 on Ubuntu)
and recompile (
cmake .. && make).
I see the error:
function transliteration(text) does not exist
Reinstall the nominatim functions with

If so then Apache cannot see the
/tmp/.s.PGSQL.5432 file. It's a good security feature,
so use the preferred solution.
However, you can solve this the quick and dirty way by commenting out that line and then run
sudo systemctl daemon-reload sudo systemctl restart httpd
Setup.php fails with the message:
DB Error: extension not found
Make sure you have the Postgres extensions hstore and postgis installed. See the installation instruction for a full list of required packages.
When running the setup.php script I get a error:
`Cannot redeclare getDB() (previously declared in /your/path/Nominatim/lib/db.php:4)`
The message is a bit misleading as PHP needs to load the file
instead re-loads Nominatim's
db.php. To solve this make sure you
have the [http://pear.php.net/package/DB/ Pear module 'DB'] installed.
sudo pear install DB
I forgot to delete the flatnodes file before starting an import.
That's fine. For each import the flatnodes file get overwritten. See https://help.openstreetmap.org/questions/52419/nominatim-flatnode-storage for more information.
