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 http://download.geofabrik.de.
|
|
For the intial import, download the countries you need and merge them.
|
|
See [OSM Help](https://help.openstreetmap.org/questions/48843/merging-two-or-more-geographical-areas-to-import-two-or-more-osm-files-in-nominatim)
|
|
for examples how to do that. Use the resulting single osm file when
|
|
running `setup.php`.
|
|
|
|
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](https://github.com/openstreetmap/Nominatim/issues/60#issuecomment-18679446)
|
|
for a script that runs the updates using osmosis.
|
|
|
|
### My website shows: `XML Parsing Error: XML or text declaration not at start of entity Location</code>.`
|
|
|
|
Make sure there are no spaces at the beginning of your `settings/local.php` file.
|
|
|
|
|
|
Installation
|
|
------------
|
|
|
|
### 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 `-index-noanalyse`.
|
|
|
|
|
|
### 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](http://www.php.net/manual/en/ini.core.php#ini.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
|
|
your `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'
|
|
|
|
Or
|
|
|
|
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 `setup.php --create--functions`
|
|
and check for any errors, e.g. a missing `nominatim.so` file.
|
|
|
|
|
|
### The website shows: `Could not get word tokens`
|
|
|
|
The server cannot access your database. Add `&debug=1` to your URL
|
|
to get the full error message.
|
|
|
|
|
|
### On CentOS the website shows `could not connect to server: No such file or directory`
|
|
|
|
On CentOS v7 the PostgreSQL server is started with `systemd`.
|
|
Check if `/usr/lib/systemd/system/httpd.service` contains a line `PrivateTmp=true`.
|
|
If so then Apache cannot see the `/tmp/.s.PGSQL.5432` file. It's a good security feature,
|
|
so use the [[#PostgreSQL_UNIX_Socket_Location_on_CentOS|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 `DB.php` and
|
|
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.
