1 # Troubleshooting Nominatim Installations
5 ### Can a stopped/killed import process be resumed?
7 "I accidentally killed the import process after it has been running for many hours. Can it be resumed?"
9 It is possible if the import already got to the indexing stage.
10 Check the last line of output that was logged before the process
11 was killed. If it looks like this:
14 Done 844 in 13 @ 64.923080 per second - Rank 26 ETA (seconds): 7.886255
16 then you can resume with the following command:
19 ./utils/setup.php --index --create-search-indices --create-country-names
22 If the reported rank is 26 or higher, you can also safely add `--index-noanalyse`.
25 ### PHP "open_basedir restriction in effect" warnings
27 `PHP Warning: file_get_contents(): open_basedir restriction in effect.`
29 You need to adjust the [open_basedir](http://www.php.net/manual/en/ini.core.php#ini.open-basedir) setting
30 in your PHP configuration (`php.ini file`). By default this setting may look like this:
32 open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/
34 Either add reported directories to the list or disable this setting temporarily by
35 dding ";" at the beginning of the line. Don't forget to enable this setting again
36 once you are done with the PHP command line operations.
39 ### PHP timzeone warnings
41 The Apache log may contain lots of PHP warnings like this:
42 `PHP Warning: date_default_timezone_set() function.`
44 You should set the default time zone as instructed in the warning in
45 your `php.ini` file. Find the entry about timezone and set it to
48 ; Defines the default timezone used by the date functions
49 ; http://php.net/date.timezone
50 date.timezone = 'America/Denver'
55 echo "date.timezone = 'America/Denver'" > /etc/php.d/timezone.ini
58 ### nominatim.so version mismatch
60 When running the import you may get a version mismatch:
61 `COPY_END for place failed: ERROR: incompatible library "/srv/Nominatim/nominatim/build/module/nominatim.so": version mismatch`
63 pg_config seems to use bad includes sometimes when multiple versions
64 of PostgreSQL are available in the system. Make sure you remove the
65 server development libraries (`postgresql-server-dev-9.5` on Ubuntu)
66 and recompile (`cmake .. && make`).
69 ### I see the error: "function transliteration(text) does not exist"
71 Reinstall the nominatim functions with `setup.php --create--functions`
72 and check for any errors, e.g. a missing `nominatim.so` file.
75 ### The website shows: "Could not get word tokens"
77 The server cannot access your database. Add `&debug=1` to your URL
78 to get the full error message.
81 ### On CentOS the website shows "Could not connect to server"
83 `could not connect to server: No such file or directory`
85 On CentOS v7 the PostgreSQL server is started with `systemd`.
86 Check if `/usr/lib/systemd/system/httpd.service` contains a line `PrivateTmp=true`.
87 If so then Apache cannot see the `/tmp/.s.PGSQL.5432` file. It's a good security feature,
88 so use the [preferred solution](../appendix/Install-on-Centos-7/#adding-selinux-security-settings).
90 However, you can solve this the quick and dirty way by commenting out that line and then run
92 sudo systemctl daemon-reload
93 sudo systemctl restart httpd
96 ### "must be an array or an object that implements Countable" warning in /usr/share/pear/DB.php
98 As reported starting PHP 7.2. This external DB library is no longer maintained and will be replaced in future Nominatim versions. In the meantime you'd have to manually change the line near 774 from
99 `if (!count($dsn)) {` to `if (!$dsn && !count($dsn))`. [More details](https://github.com/openstreetmap/Nominatim/issues/1184)
104 ### Website reports "DB Error: insufficient permissions"
106 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`.
108 1. Repeat the `createuser` step of the installation instructions.
110 2. Give the user permission to existing tables
113 GRANT usage ON SCHEMA public TO "www-data";
114 GRANT SELECT ON ALL TABLES IN SCHEMA public TO "www-data";
117 ### Website reports "Could not load library "nominatim.so"
119 Example error message
122 SELECT make_standard_name('3039 E MEADOWLARK LN') [nativecode=ERROR: could not
123 load library "/srv/nominatim/Nominatim-3.1.0/build/module/nominatim.so":
124 /srv/nominatim/Nominatim-3.1.0/build/module/nominatim.so: cannot open shared
125 object file: Permission denied
126 CONTEXT: PL/pgSQL function make_standard_name(text) line 5 at assignment]
129 The Postgresql database, i.e. user postgres, needs to have access to that file.
131 The permission need to be read & executable by everybody, e.g.
134 -rwxr-xr-x 1 nominatim nominatim 297984 build/module/nominatim.so
137 Try `chmod a+r nominatim.so; chmod a+x nominatim.so`.
139 When running SELinux, make sure that the
140 [context is set up correctly](../appendix/Install-on-Centos-7/#adding-selinux-security-settings).
142 ### Setup.php fails with "DB Error: extension not found"
144 Make sure you have the Postgres extensions hstore and postgis installed.
145 See the installation instruction for a full list of required packages.
148 ### Setup.php reports "Cannot redeclare getDB()"
150 `Cannot redeclare getDB() (previously declared in /your/path/Nominatim/lib/db.php:4)`
152 The message is a bit misleading as PHP needs to load the file `DB.php` and
153 instead re-loads Nominatim's `db.php`. To solve this make sure you
154 have the [Pear module 'DB'](http://pear.php.net/package/DB/) installed.
158 ### I forgot to delete the flatnodes file before starting an import.
160 That's fine. For each import the flatnodes file get overwritten.
161 See [https://help.openstreetmap.org/questions/52419/nominatim-flatnode-storage]()
162 for more information.
165 ## Running your own instance
167 ### Can I import multiple countries and keep them up to date?
169 You should use the extracts and updates from https://download.geofabrik.de.
170 For the initial import, download the countries you need and merge them.
171 See [OSM Help](https://help.openstreetmap.org/questions/48843/merging-two-or-more-geographical-areas-to-import-two-or-more-osm-files-in-nominatim)
172 for examples how to do that. Use the resulting single osm file when
175 For updates you need to download the change files for each country
176 once per day and apply them **separately** using
178 ./utils/update.php --import-diff <filename> --index
180 See [this issue](https://github.com/openstreetmap/Nominatim/issues/60#issuecomment-18679446)
181 for a script that runs the updates using osmosis.
183 ### Can I import negative OSM ids into Nominatim?
185 See [this question of Stackoverflow](https://help.openstreetmap.org/questions/64662/nominatim-flatnode-with-negative-id).
187 ### Missing XML or text declaration
189 The website might show: `XML Parsing Error: XML or text declaration not at start of entity Location.`
191 Make sure there are no spaces at the beginning of your `settings/local.php` file.
