+# Troubleshooting Nominatim Installations
-### Can I import multiple countries and 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](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.

-See [https://help.openstreetmap.org/questions/64662/nominatim-flatnode-with-negative-id]()
-
-### Missing XML or text declaration
-
-The website might show: `XML Parsing Error: XML or text declaration not at start of entity Location.`
-
-Make sure there are no spaces at the beginning of your `settings/local.php` file.

-# Installation
+## Installation Issues
### Can a stopped/killed import process be resumed?
then you can resume with the following command:
```sh
-./utils/setup.php --index --create-search-indices --create-country-names
+nominatim import --continue indexing
```
If the reported rank is 26 or higher, you can also safely add `--index-noanalyse`.
+### PostgreSQL crashed "invalid page in block"
+
+Usually serious problem, can be a hardware issue, not all data written to disc
+for example. Check PostgreSQL log file and search PostgreSQL issues/mailing
+list for hints.
+
+If it happened during index creation you can try rerunning the step with
+
+```sh
+nominatim import --continue indexing
+```
+
+Otherwise it's best to start the full setup from the beginning.

### PHP "open_basedir restriction in effect" warnings
- `PHP Warning: file_get_contents(): open_basedir restriction in effect.`
+ 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:

-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.

-### PHP timzeone warnings
+### PHP timezeone warnings
The Apache log may contain 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
+ ; https://php.net/date.timezone
date.timezone = 'America/Denver'
Or
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-9.5` on Ubuntu)
+server development libraries (`postgresql-server-dev-13` on Ubuntu)
and recompile (`cmake .. && make`).
-### I see the error: "function transliteration(text) does not exist"
+### I see the error "ERROR: permission denied for language c"
-Reinstall the nominatim functions with `setup.php --create--functions`
-and check for any errors, e.g. a missing `nominatim.so` file.
+`nominatim.so`, written in C, is required to be installed on the database
+server. Some managed database (cloud) services like Amazon RDS do not allow
+this. There is currently no work-around other than installing a database
+on a non-managed machine.
-### The website shows: "Could not get word tokens"
+### I see the error: "function transliteration(text) does not exist"
-The server cannot access your database. Add `&debug=1` to your URL
-to get the full error message.
+Reinstall the nominatim functions with `nominatim refresh --functions`
+and check for any errors, e.g. a missing `nominatim.so` file.
+
+### I see the error: "ERROR: mmap (remap) failed"
+This may be a simple out-of-memory error. Try reducing the memory used
+for `--osm2pgsql-cache`. Also make sure that overcommitting memory is
+allowed: `cat /proc/sys/vm/overcommit_memory` should print 0 or 1.
-### On CentOS the website shows "Could not connect to server"
+If you are using a flatnode file, then it may also be that the underlying
+filesystem does not fully support 'mmap'. A notable candidate is virtualbox's
+vboxfs.
-`could not connect to server: No such file or directory`
+### nominatim UPDATE failed: ERROR: buffer 179261 is not owned by resource owner Portal
-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 [preferred solution](../appendix/Install-on-Centos-7/#adding-selinux-security-settings).
+Several users [reported this](https://github.com/openstreetmap/Nominatim/issues/1168)
+during the initial import of the database. It's
+something PostgreSQL internal Nominatim doesn't control. And PostgreSQL forums
+suggest it's threading related but definitely some kind of crash of a process.
+Users reported either rebooting the server, different hardware or just trying
+the import again worked.
-However, you can solve this the quick and dirty way by commenting out that line and then run
+### The website shows: "Could not get word tokens"
- sudo systemctl daemon-reload
- sudo systemctl restart httpd
+The server cannot access your database. Add `&debug=1` to your URL
+to get the full error message.
### Website reports "DB Error: insufficient permissions"
-The user the webserver, e.g. Apache, runs under needs to have access to the Nominatim database. You can find the user like [this](https://serverfault.com/questions/125865/finding-out-what-user-apache-is-running-as), for default Ubuntu operating system for example it's `www-data`.

Try `chmod a+r nominatim.so; chmod a+x nominatim.so`.
-### Setup.php fails with "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 you recently updated your operating system, updated PostgreSQL to
+a new version or moved files (e.g. the build directory) you should
+recreate `nominatim.so`. Try
-### Setup.php reports "Cannot redeclare getDB()"
+```
+ cd build
+ rm -r module/
+ cmake $main_Nominatim_path && make
+```
-`Cannot redeclare getDB() (previously declared in /your/path/Nominatim/lib/db.php:4)`
+### Setup.php fails with "DB Error: extension not found"
-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 [Pear module 'DB'](http://pear.php.net/package/DB/) installed.
+Make sure you have the PostgreSQL extensions "hstore" and "postgis" installed.
+See the installation instructions for a full list of required packages.
- 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.
